The output indicates that port channel 1 is trunking, which means it is configured to be an Inter-Switch Link (ISL). ISLs are used in Fibre Channel networks to connect switches and maintain the fabric topology. The “port mode is F” in the output also confirms that it’s an ISL, as F-ports are used for Fabric (switch) ports connecting to N-ports on another switch or node.

To facilitate communication between the APIC controller and an OpenStack OpFlex agent, it’s necessary to enable the Infra VLAN on the Attachable Access Entity Profile (AAEP). The AAEP is used in Cisco ACI to group interfaces that share common policies and extending the Infra VLAN to these interfaces allows the OpFlex agent, which is part of the Cisco Application Centric Infrastructure (ACI), to communicate with the APIC controller. This setup is crucial for the OpFlex agent to function correctly, as it relies on the Infra VLAN for communication with the APIC controller1.

 Terraform is an infrastructure as code (IaC) tool that allows users to define both cloud and on-premises resources in human-readable configuration files that can be versioned, reused, and shared. In the context of Cisco Data Center Core Technologies, Terraform can be used to enforce the desired state of the network by automatically managing, updating, and reverting configurations as needed to maintain consistency. It supports a wide range of Cisco products and can be extended to manage server infrastructure in the future.

References: The Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course provides insights into the essentials of automation and security in data centers, including the use of IaC tools like Terraform for enforcing desired state configuration1. Additionally, the Implementing Automation for Cisco Data Center Solutions (DCAUI) course further explores the implementation of automation solutions, including Terraform, in Cisco data centers2

 In Cisco UCS Central, user privileges are managed through roles and locales. When a user moves departments, their access privileges need to be updated to reflect their new role. By creating a new locale for the Admin department and adding the user to this locale, the user’s access privileges are updated to include the Admin department’s data and applications. The old Finance locale should be deleted, or the user should be removed from it, to revoke the previous access privileges1.

 The command aaa authentication login default group ISE local configures the Cisco Nexus Series Switch to use TACACS+ for authentication by default and specifies a fallback to local authentication if the TACACS+ server becomes unavailable. This ensures that users are authenticated against the TACACS+ server when it is available, but allows them to use local switch credentials if the server cannot be reached, meeting the requirement for failover to local account1.

References :=

• Cisco documentation on configuring TACACS+ for Cisco Nexus Series Switches provides detailed steps and explanations for setting up authentication and ensuring failover to local accounts

 When storm control is applied to an interface with a zero percent value, it means that the switch will not tolerate any traffic that exceeds the bandwidth of the interfaces during a streaming window. The switch monitors the levels of incoming broadcast, multicast, and unicast traffic over a 1-second interval. When the configured threshold level is reached, further traffic in this category is dropped until the level falls below the threshold.

EIGRP authentication is used to prevent unauthorized devices from forming neighbor relationships. The correct CLI commands to establish EIGRP neighborship with authentication on Cisco Nexus switches involve configuring the interface with EIGRP, setting the EIGRP autonomous system number, and specifying the authentication key and key-chain. The commands in Option A are consistent with these requirements, hence it is the verified answer.

References: = For further details, you can refer to the official Cisco documentation on EIGRP authentication and configuration for Nexus switches available on the Cisco website.

 To configure a Fibre Channel device alias named TEST for a device attached to port fc1/9 on a Cisco Nexus Series Switch, the correct command set is found in Option A. The commands should be entered in configuration mode, starting with accessing the device-alias database, creating the device-alias named TEST with the specified pwwn, and committing the changes to the database123.

References := The process for configuring a Fibre Channel device alias on a Cisco Nexus Series Switch is detailed in the Cisco Nexus 9000 Series NX-OS SAN Switching Configuration Guide and other Cisco documentation related to SAN switching and device aliases

To implement traffic monitoring for a server vNIC with fabric failover enabled, ensuring that traffic is sent to an analyzer even during a fabric interconnect failure, the correct configuration is to create two traffic monitoring sessions with different names, one per fabric, and connect an analyzer on each FI as the destination for the monitoring session local to the FI. This setup allows continuous monitoring because if one fabric interconnect fails, the other can still send traffic to its connected analyzer2.

References := Cisco Community Discussion on Understanding Fabric Failure and Failover in UCS

The configuration in option C, which includes commands such as switchport port-security, switchport port-security violation restrict, and switchport port-security mac-address sticky, meets the security requirements specified. This configuration secures the end-user ports by limiting the number of MAC addresses allowed on the port, logs security breaches without shutting down the port (restrict mode), and retains the MAC address configuration even if the device restarts (sticky option).

The attribute that must be selected to implement microsegmentation of endpoints within the same IP subnet using a network-based attribute that allows IP subnet independence is the Tag attribute. The Tag attribute is a user-defined attribute that can be assigned to endpoints based on any criteria, such as location, function, or security level. The Tag attribute can be used to create microsegmentation policies in ACI, which define the rules for communication between endpoints within the same or different bridge domains. The Tag attribute enables IP subnet independence, which means that the microsegmentation policies are not tied to the IP subnet of the endpoints, and can be applied across different subnets or even different fabrics. The Tag attribute also simplifies the management and scalability of microsegmentation policies, as it does not require the use of IP addresses or MAC addresses to identify endpoints. References :=

The ip ospf passive-interface command is used to prevent OSPF adjacency and routing updates from being sent or received on a specific interface, while still advertising the interface subnet via OSPF. This command is useful for stub networks or loopback interfaces that do not need to form OSPF neighbor relationships. The other commands either enable OSPF adjacency by default, change the OSPF network type, or disable OSPF passive mode. References:

The vsan bind interface command is used to statically assign VSAN membership to a virtual Fibre Channel interface. This command overrides the VSAN membership that is derived from the physical interface or the default VSAN. The other commands are either invalid or do not apply to virtual Fibre Channel interfaces. References:

 The configuration in Option D is a scheduler configuration for creating backup jobs. It specifies a schedule name, job name, and the command to copy configurations to a server in the operations VRF using TFTP protocol. The time start and repeat options are used to schedule two backup jobs per day.

 Configuring an IP helper address on interface VLAN 10 of the management switch is the correct action to meet the requirements. This configuration allows the management switch to forward DHCP requests from the new switches in different VLANs to the DCNM server, which can then use the zero-touch POAP feature to facilitate fabric creation.

The command rollback running-config checkpoint system-fm-pim-best-effort is used to restore the configuration changes made by disabling the PIM feature and skipping any errors. In Cisco Data Center Core Technologies, it’s essential to understand that rollback is a feature that allows administrators to take a snapshot of the configuration before making changes, so they can quickly roll back if needed. The system-fm-pim-best-effort option ensures that the rollback occurs even if there are errors encountered during the process, ensuring that as much of the previous state is restored as possible.

By default, Cisco UCS Manager excludes local disks from a host firmware package to avoid data loss or corruption during firmware upgrades. The host firmware package contains firmware for other components like network interface controllers, storage controllers, etc., but excludes local disks as they might contain sensitive data.

One of the benefits of independent resource scaling in Cisco HyperFlex hybrid architecture is the flexible expansion of compute, caching, and capacity. This allows for the addition of resources in the required ratios without being constrained by the limitations of traditional converged infrastructure3.

The statement that applies to a Cisco Nexus 5600 Series switch when performing a rollback is that errors are skipped when an atomic rollback type is triggered. An atomic rollback is a type of rollback that implements the checkpoint configuration only if no errors occur during the process. If any errors are encountered, the rollback is aborted and the running configuration is restored to its previous state. This ensures that the switch does not end up in a partially configured or inconsistent state. The other statements are not true because:

• A user who is assigned to the network-operator user role cannot perform a rollback. The network-operator user role has read-only access to the switch and cannot modify the configuration. To perform a rollback, the user must have the network-admin or vdc-admin user role.
• The configuration rollback functionality is not disabled when FCoE is enabled. The rollback feature is supported on all Cisco Nexus 5600 Series switches regardless of the FCoE configuration. However, some FCoE-related commands may not be rolled back due to dependencies or conflicts with other features.
• A system checkpoint is not generated automatically when the running configuration is saved to NVRAM. A system checkpoint is a predefined checkpoint that contains the last saved configuration of the switch. A system checkpoint is created or updated only when the user explicitly saves the running configuration to the startup configuration using the copy running-config startup-config command or its alias, copy run start. References: For more details on how to configure and use the rollback feature on a Cisco Nexus 5600 Series switch, please refer to the following resources:

 The HA NOT READY status on a Cisco Fabric Interconnect typically indicates that the system is not in a state to provide High Availability due to certain connectivity issues. In this case, the status message “No device connected to this Fabric Interconnect” suggests that there is no connectivity through the management ports. Establishing a connection through these ports is essential for the Fabric Interconnect to communicate with other devices in the network and form a High Availability cluster. Once the management ports are connected and properly configured, the HA NOT READY status should be resolved.

References := This explanation is based on standard procedures for addressing High Availability issues in Cisco Data Center environments, as outlined in Cisco’s technical documentation and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials

Platform as a Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. Public cloud services are offered over the internet and are available to anyone who wants to purchase or use them. They are ideal for an engineer with a small budget and limited technical knowledge because they provide a cost-effective, scalable infrastructure that can grow with customer demand2.

Option A is the correct command set to configure an extra keyring in Cisco UCS Manager. The commands create a keyring named “extra” with a modulus of 4096 bits, which provides a high level of encryption. The commands also generate a self-signed certificate for the keyring, which enables secure authentication when users use the web interface. References:

 Before enabling a Cisco UCS Manager domain for Cisco Intersight connectivity, you must configure the DNS servers and the NTP servers for the domain. The DNS servers are required to resolve the hostname of the Cisco Intersight service (svc.intersight.com) and the NTP servers are required to synchronize the time between the Cisco UCS Manager and the Cisco Intersight service. These settings ensure that the Cisco UCS Manager can establish a secure and reliable connection with the Cisco Intersight service and register the domain with the Cisco Intersight account.

 The command “alert-group Inventory user-def-cmd show logging last 100” is used to configure the Smart Call Home feature to generate an email with the last 100 lines of the log when new hardware is inserted. This command specifies the alert group ‘Inventory’ and the user-defined command to show the last 100 lines of the logging buffer

Option A is the correct configuration to meet the requirements of configuring system logging on the MDS switch. The commands set the console logging level to 5, which corresponds to the severity level of “warning” and above, and set the exec-timeout to 300 seconds, which means that the users will be logged out of the console after 5 minutes of inactivity. The other options are either incorrect or incomplete for the task. References:

Ansible is known for its agentless architecture, which means it does not require a software agent to be installed on the target nodes it manages. This contrasts with tools like Puppet and Chef, which typically require an agent to be installed on each node. Ansible uses SSH or WinRM to communicate with the nodes, making it simpler and more secure as it reduces the attack surface and the overhead of managing agents.

The configuration set in Option C is designed to invoke a Python script when the router becomes unreachable. It uses an event scheduler to track the state of the router and, if it is not up, it triggers the Python script “routerdown.py” at specified intervals. This setup ensures that the operations team is alerted promptly when the router DC-RTR-1 becomes unreachable, allowing for quick response and troubleshooting.

To set access to Cisco IMC (Integrated Management Controller) and allow logging onto the https://datacenter.local  web page, the correct set of commands is found in option C. These commands will configure the network settings on the Cisco UCS C240 Series Server to enable web access to the Cisco IMC interface. The configuration typically involves setting the correct IP address, gateway, and other network parameters that align with the data center’s network design.

 Option C is the correct configuration to apply a power redundancy policy on a Cisco UCS C-Series Rack Server that supports two power sources. The power redundancy policy determines how the server uses the available power supplies to optimize power usage. The grid option means that the server uses power from both power supplies simultaneously. If one power supply fails, the server continues to operate with the remaining power supply. The other options are not suitable for this requirement. The n+1 option means that the server uses one fewer power supply than the number of power supplies that are installed. If a power supply fails, the server uses the extra power supply. The non-redundant option means that the server uses only one power supply, regardless of the number of power supplies that are installed. If the power supply fails, the server shuts down. The ps-redundant option means that the server uses power from the most efficient power supply. If the power supply fails, the server switches to another power supply. References:

The Python code snippet provided imports the json module and loads a JSON file into a variable named var1. Since JSON files inherently represent object data as dictionaries in Python, the resulting data structure is a dictionary. This is evident from the output shown, which displays a dictionary with nested dictionaries and lists, containing keys like ‘bd’, ‘ap’, ‘name’, etc., and corresponding values.

References := The explanation is based on standard Python data structures and JSON file handling as described in Python documentation and typical Python programming resources. JSON objects are represented as dictionaries in Python, which is a fundamental concept in working with JSON data in the language.

To create a VSAN on the network, the engineer needs to select Fabric A from the drop-down menu. This will allow the engineer to assign a VSAN ID and a name to the new VSAN, and to add members to the VSAN. The other options are not relevant for creating a VSAN. Fabric B is the other fabric interconnect, FC Zoning Enabled is a feature that allows traffic isolation within a VSAN, and Common/Global is a default VSAN that cannot be modified. References:

In Cisco UCS, modifying user accounts involves several considerations. Disabling a user account does indeed maintain all the data in the Cisco UCS Fabric Interconnect, which means that the user’s settings and privileges are retained even though the account is inactive (A). Local user accounts have precedence over remote authentication server accounts. This means that if a user account exists both locally and on a remote server like TACACS, RADIUS, or LDAP, the local account settings will take priority (D).

References := Managing User Accounts - Cisco1.

 The QoS policy that controls only vHBA traffic is the Fibre Channel policy. In Cisco UCS, the Fibre Channel policy is specifically designed to manage the quality of service for traffic related to virtual Host Bus Adapters (vHBAs), which are used for Fibre Channel over Ethernet (FCoE) storage networking. This policy ensures that the storage traffic is appropriately prioritized and managed within the system.

References:

• Cisco UCS Manager GUI Configuration Guide, which provides details on configuring QoS policies for vHBA traffic.
• Cisco Data Center Core Technologies (DCCOR) study materials, which cover the concepts of QoS and vHBA configuration in a Cisco data center environment.

 Embedded Event Manager (EEM) is a powerful tool used in Cisco devices, including MDS switches, to automate tasks and create custom scripts that react to network events. For an administrator needing to configure an automated policy to shut down a link when a threshold is exceeded, EEM is the appropriate feature to use. It allows the creation of event-driven automation scripts that can be triggered when certain conditions are met, such as a link exceeding a specified threshold.

References: Cisco Data Center Core Technologies (DCCOR) training materials and Cisco’s official documentation on EEM.

To enable port security on all Cisco MDS series switches in the fabric and avoid the extensive manual configuration of the switch ports, the network engineer must activate the CFS (Cisco Fabric Services) distribution and enable the auto-learning port security feature on a per-VSAN basis. CFS is a protocol that allows the switches to distribute and synchronize configuration information across the fabric. By activating the CFS distribution for port security, the network engineer can propagate the port security configuration to all the switches in the fabric automatically, without having to configure each switch individually. The auto-learning port security feature allows the switches to learn and store the port security information of the devices that are already logged in and authorized on the ports, and prevent any unauthorized devices from logging in. The auto-learning port security feature can be enabled on a per-VSAN basis, which means that the port security information is specific to each VSAN and does not affect other VSANs. This provides more flexibility and granularity for the port security configuration. References :=

Option A is the correct order of reloading components during the process of upgrading the EPLDs of the fabric modules for a Cisco MDS director-class switch. The EPLD upgrade is performed on one fabric module at a time, and the fabric module is reloaded after the upgrade. The other fabric modules and the switching platform are not reloaded during the process. References:

The question involves an engineer configuring a Cisco MDS 9000 Series Switch and noticing that the name server with IP 192.168.10.11 is missing from the configuration. The correct action to complete the configuration is option C, “Enter yes at step 21 to edit the configuration. Add the line dns-server 192.168.10.11.” This step allows the engineer to modify the initial setup process’s outcome by adding the missing DNS server information directly into the configuration before saving it.

A strict CoPP (Control Plane Policing) policy is designed to manage the traffic flow of control plane packets to protect the control plane of routers and switches from being overwhelmed by unnecessary or malicious traffic. When a ping sweep, which involves sending ICMP echo requests to multiple hosts to identify live devices on a network, is performed on a network connected through a switch with a strict CoPP policy, excess ICMP packets can be dropped to prevent them from consuming excessive resources. References: Cisco Data Center Core Technologies source documents or study guide

The Cisco UCS firmware Auto Sync Server policy includes several configuration settings that determine how and when firmware on servers is synchronized. The two available settings from the options provided are ‘User Acknowledge’ and ‘No Action’. ‘User Acknowledge’ requires an administrator to manually acknowledge firmware upgrades in the Pending Activities dialog box before they are applied. ‘No Action’ means no firmware upgrade is initiated on the server. These settings allow administrators to control the firmware synchronization process according to their operational policies and procedures.

The ‘Full State’ backup type in Cisco UCS Manager is designed to capture a snapshot of the entire system, which includes all configuration settings, system logs, and the operating system. This comprehensive backup can be used to fully restore the system in the event of a disaster recovery scenario. The ‘Full State’ backup is the only option that provides a complete system snapshot, making it the ideal choice for disaster recovery purposes.

References: The information regarding backup types and their purposes can be found in the Cisco Data Center Core Technologies source book, specifically in the section discussing system maintenance and backups within the Cisco UCS Manager platform.

POAP is an automatic provisioning and zero-touch deployment feature that assists device owners in the

initial deployment and configuration of Nexus switches.

The feature works by checking for a local configuration script. If the script has been deleted, the switch has

been reset to factory settings, or this is the first boot-up, the POAP daemon will connect to a preset list of

servers to download an initial configuration file.

To perform this operation, the switch must first obtain an IP address from a local DHCP server. POAP

configuration settings can also be passed through the DHCP response.

Which conditions should be verified, so they need to be TRUE. Like no startup (A) and bootup (B). C means

that it needs to miss a license file and E means it needs to miss an NX-OS image.

The correct configuration to capture traffic only from the server with the IP address of 198.19.1.19/24 is option C. This configuration uses an IP access list to match packets from the specific IP address with a subnet mask of 255.255.255.255, which indicates a single host. The monitor session command is then used to apply this access list to a SPAN session, ensuring that only traffic from the specified server is captured.

The src-dst-port load balancing method ensures that frames in the same flow (identified by the source and destination ports) follow the same links in a port channel. This method is effective in environments with Cisco MDS 9000 Series Switches because it maintains the order of frame delivery within a flow, which is crucial for storage traffic. Subsequent flows can use different links, allowing for efficient utilization of the port channel bandwidth. References: Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials.

Two statements that are true about the process of performing an EPLD upgrade on a Cisco MDS 9000 series Switch are:

• If an upgrade is interrupted, the upgrade continues after a connection is restored. This means that the EPLD upgrade process is resilient to network or power failures and can resume from where it left off once the connection is reestablished.
• The upgrade can be performed from the standby supervisor module. This allows the active supervisor module to continue to provide management and control functions while the EPLD upgrade is in progress. The standby supervisor module can also take over the active role if needed during the upgrade.

The other statements are not true because:

• The active supervisor cannot be upgraded. The EPLD upgrade process requires the supervisor module to be in standby mode before it can be upgraded. The active supervisor module must be switched to standby mode manually or automatically before the upgrade can begin.
• Modules do not need to be online to be upgraded. The EPLD upgrade process can upgrade modules that are offline or powered down as well as modules that are online. The offline modules are upgraded when they are brought online or powered up.
• The upgrade process disrupts all modules that are being upgraded. The EPLD upgrade process requires a module reload for each module that is being upgraded, which causes a temporary disruption of traffic and services on that module. The disruption can be minimized by using hitless or non-disruptive EPLD upgrade modes, which preserve the forwarding state and configuration of the module during the reload. References: For more details on how to perform an EPLD upgrade on a Cisco MDS 9000 series Switch, please refer to the following resources:

To monitor all LAN traffic on Fabric A from a blade server, the source should be configured as all uplink Ethernet ports in the test-span monitor session. This configuration allows the engineer to capture all LAN traffic that traverses the uplink Ethernet ports, providing a comprehensive view of the network activity related to Fabric A. By monitoring these ports, the engineer can analyze traffic patterns, detect anomalies, and ensure the proper functioning of the network.

To complete the PowerOn Auto Provisioning (POAP) operation on a Cisco Nexus 9000 Series Switch, the script must include the necessary network information such as the interface IP address, gateway, and DNS server IP addresses. Option C likely contains this information, which is essential for the switch to locate a DHCP server, bootstrap itself, and download the configuration script for software image installation and configuration

 PowerOn Auto Provisioning (POAP) on Cisco Nexus 9000 Series Switches automates the process of upgrading software images and installing configuration files on devices being deployed for the first time. When a device with POAP boots without a startup configuration, it enters POAP mode, locates a DHCP server, and bootstraps itself with its interface IP address, gateway, and DNS server IP addresses. The device also obtains the IP address of a TFTP server and downloads a configuration script that enables the switch to download and install the appropriate software image and configuration file. Since only UDP is permitted between the Nexus 9000 switch and the server hosting the Cisco NX-OS system images, the TFTP transfer protocol, which uses UDP, must be defined1.

• Cisco Nexus 9000 Series NX-OS Fundamentals Configuration Guide, which details the use of POAP and the requirements for network infrastructure including a DHCP server and a TFTP server

 Changing the boot order during setup and applying new requirements multiple times can be achieved by setting the boot configuration directly through the BIOS. This allows the engineer to modify the boot order as needed, separate from the configured boot order in Cisco IMC. References: The DCCOR course discusses server boot order configuration and the use of BIOS settings for such purposes.

 Option B and E are the correct configuration sets that must be used to meet the requirements. Option B enables the user role distribution in DC1 by setting the role distribution policy to enabled and the role distribution scope to global. Option E constrains the NTP and call home features to DC2 by setting the NTP and call home policies to local and assigning them to the DC2 fabric interconnects. References:

 PowerOn Auto Provisioning (POAP) is a feature that automates the process of upgrading software images and installing configuration files on Cisco devices that are deployed in a network for the first time. It is particularly useful for scenarios where multiple switches need to be provisioned without manual intervention. When a switch with POAP boots up and does not find a startup configuration, it enters the POAP mode, locates a DHCP server, and bootstraps itself with its interface IP address, gateway, and DNS server IP address. It then obtains the IP address or URL of a TFTP server and downloads the necessary scripts and software images to configure the device12.

References: More information about POAP and its configuration can be found in Cisco’s official documentation

The data interchange format presented in the output is JSON (JavaScript Object Notation), which is commonly used for transmitting data in web applications and for configuration files. It is easily readable both by humans and machines.

For detailed explanations and references, it’s best to consult the official Cisco documentation or the Cisco Data Center Core Technologies study guide.

Option C and E are the correct requirements when planning a Cisco HyperFlex All Flash standard cluster installation using three HX240c M5 servers. Option C states that if the Jumbo MTU option in the HyperFlex installer is enabled, then jumbo frames must also be enabled on the upstream switches, which is true for optimal performance and compatibility. Option E states that the servers must be discovered, unassociated, and connected to each fabric interconnect, which is also true for the cluster installation process. The other options are either false or not applicable for the scenario. References:

DTLS (Datagram Transport Layer Security) is designed to provide security for datagram-based applications by allowing them to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. It is suitable for securing JSON encoded telemetry data sent to an external collector1.

 Including EPG-2, EPG-3, and EPG-4 in the preferred group allows these EPGs to communicate with each other without requiring any contracts. This is because the preferred group feature in Cisco ACI allows EPGs within the same VRF to communicate by default. However, since the secure server in EPG-1 must provide services to EPG-2, a contract is required between EPG-1 and EPG-2 to facilitate this communication while maintaining the security and policies necessary for the server.

References := For more detailed information on configuring EPGs and contracts in Cisco ACI, you can refer to the Cisco Data Center Core Technologies (DCCOR) study materials and official Cisco documentation. These resources provide comprehensive guidance on the implementation and management of EPGs, contracts, and preferred groups within a Cisco ACI environment.

 The correct answer is option C. The fabric binding configuration in option C matches the output required for the Cisco MDS 9000 Series Switch. Fabric binding enhances the security of the SAN fabric by allowing only authorized switches to join the fabric. The configuration includes specifying the switch world wide name (swwn), domain ID, and member world wide node name (nwwn) to ensure that only the specified devices can participate in the fabric.

References: For more information on fabric binding and its configuration, you can refer to the Cisco MDS 9000 Series Fabric Switches Configuration Guide and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) study materials.

 The auditor requires read-only access to perform the configuration review. The permit command show * grants the auditor access to all show commands, which are typically used to view configurations and statuses without making changes, thus maintaining the read-only requirement. References: This is aligned with the best practices for role-based access control (RBAC) in Cisco Nexus switches, as detailed in the DCCOR course materials.

 SSH (Secure Shell) is the protocol that allows secure remote login from one computer to another. It provides strong authentication and secure communications over unsecured channels. This protocol is preferred for automated onboarding of devices like Cisco Nexus 9000 Series Switches because it supports strong encryption and credential-based authentication, which aligns with the requirement for minimal connection methods and security. SSH is commonly used in network automation for secure command execution and file transfers1.

References := For more information on configuring Cisco Nexus 9000 Series Switches for automation and integration with systems like Cisco UCS Director, you can refer to the Cisco Nexus 9000 Series NX-OS Programmability Guide, which details the supported manageability features and advanced automation capabilities, including Power On Auto Provisioning (POAP) and integration with automation frameworks

The system will automatically revert to the backup image version if the endpoint fails to boot from the new firmware image. This is a feature of the Fabric Interconnects that ensures high availability and reliability. The GOLD firmware image is used for diagnostics and troubleshooting, not for normal operation. The kickstart image is used for booting the Nexus switches, not the Fabric Interconnects. References:

 Promiscuous mode (D) allows a virtual machine to observe all traffic on the virtual switch, which is necessary for the virtual machine to receive all frames. VLAN (E) is used to map the frames to a specific Layer 2 network. These settings ensure that the virtual machine receives all traffic for the specified VLAN, fulfilling the requirements stated in the question1.

References: The configuration details and the role of these settings can be found in the Cisco documentation related to VDS port group parameters managed by APIC

The FCoE Initialization Protocol (FIP) uses a 24-bit FC-MAP and concatenates a 24-bit Fibre Channel ID to create a fabric-provided MAC address. This is part of the FIP’s role in establishing and maintaining the virtual links between an E-Node and the Fibre Channel Forwarder (FCF). The MAC address is essential for the E-Node to participate in FCoE communications within the fabric. The process ensures that each E-Node has a unique address on the Ethernet network, which encapsulates the Fibre Channel frames for transport. References := Cisco MDS 9000 Series FCoE Configuration Guide, Release 9.x

 A full state backup is the appropriate choice when an engineer needs to perform a backup and restore in Cisco UCS for disaster recovery purposes. This type of backup includes a snapshot of the entire system and is saved as a binary file. Importantly, full state backups are encrypted, ensuring that passwords and other sensitive information are not stored as clear text12. While TFTP (Trivial File Transfer Protocol) is not secure by itself, the encryption of the full state backup file provides the necessary security for the passwords within the backup.

In OSPF, the router with the highest priority on a network becomes the Designated Router (DR), responsible for generating LSAs for the network. By default, all Cisco routers have an OSPF priority of 1. To ensure that SW2 becomes the DR and controls the LSA floods, its priority needs to be the highest in the OSPFv2 area. The command in option A sets the OSPF priority to the maximum value of 255, which will make SW2 the most likely candidate to be elected as the DR, provided that no other router has a higher priority or a higher router ID if priorities are equal.

References := This explanation is based on the OSPF election process as described in Cisco’s OSPF design guide and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials. For detailed information, please refer to these resources.

 The solution that meets the requirements for implementing an automation solution to allow the backup of the configuration of Cisco Nexus series switches to a centralized location is the Guest Shell. The Guest Shell is a Linux-based container that runs on the Cisco Nexus operating system and provides a secure environment for running Python scripts and custom applications. The Guest Shell supports the RPM packaging format, which allows the team-developed custom monitoring scripts to be easily installed and managed. The Guest Shell is isolated from the underlying Cisco Nexus operating system, which means that it has no impact on the operating system if the resource contention occurs. The Guest Shell also allows the use of Python to expand the existing automation framework, such as using the NX-API or the Cisco Nexus Python SDK to interact with the switch configuration and state. References :=

A logical configuration backup in Cisco UCS Manager includes the AAA and RBAC settings and is stored in a human-readable format. This backup type is suitable for backing up configurations that need to be easily reviewed and audited.

Cisco CloudCenter is the appropriate orchestration solution for the customer’s requirements. It supports the CI/CD model, which is essential for streamlining operations and optimizing costs. Cisco CloudCenter can integrate with Cisco ACI networking and Cisco UCS servers, providing a unified management platform. It also offers on-premises Kubernetes support and AppDynamics performance monitoring without the need to install local clients on managed products, aligning with the customer’s security requirements. References: Cisco CloudCenter documentation and Cisco Data Center Core Technologies study guide.

Cisco HyperFlex All-Flash Stretched clusters provide a higher number of Input/Output Operations Per Second (IOPS) compared to All-HDD Stretched clusters. This is due to the faster data access speeds of flash storage, which results in better performance and lower latency for applications, especially those requiring high throughput and fast processing2

 To meet the requirement of collecting show command data every 30 seconds and sending it to receivers, the command must specify the sample interval in milliseconds. Therefore, the correct command is Snsr-grp 200 sample-interval 30000, which sets the sample interval to 30,000 milliseconds (equivalent to 30 seconds).

References := The configuration details for streaming telemetry on a Cisco MDS 9000 series switch can be found in the Cisco MDS 9000 Series SAN Analytics and SAN Telemetry Streaming Configuration Guide1.

• Setting the RADIUS source interface to be mgmt0 for group RAD1 and VLAN 22 for group RAD2 © ensures that login requests from the console and SSH are sourced from the correct interfaces and reach the appropriate RADIUS server.
• Configuring the authentication login to use group RAD1 for console and group RAD2 for remote access (D) directs the switch to use the specified RADIUS server groups for the respective login methods, aligning with the user’s requirements.

These configurations ensure that management access via console and SSH is authenticated through the designated RADIUS servers as intended. It’s important to apply these settings correctly in the switch’s configuration to achieve the desired access control.

 Enabling the DHCP relay agent on a switch allows it to forward DHCP BOOTREQUEST packets from clients to a DHCP server, even if they are not on the same physical subnet. This is crucial for clients to obtain an IP address and other network configuration parameters from a DHCP server that is not locally present on the subnet.

References: Detailed information on DHCP relay agents can be found in the Cisco Data Center Core Technologies (DCCOR) study guide or source documents, particularly in the chapters discussing DHCP configuration and management in network environments.

To test connectivity from the guest shell of the NX-OS, the command that should be used is ping vrf management [IP address]. This command sends ICMP Echo requests to the specified IP address within the management VRF, which is useful for verifying network connectivity from the guest shell environment.

References := For more detailed procedures and explanations, one would refer to the Cisco Data Center Core Technologies (DCCOR) study materials, which provide in-depth knowledge on managing and operating Cisco Nexus switches and their features, including the use of the guest shell for network connectivity tests.

 In an FCoE environment, the PAUSE mechanism is used to provide lossless behavior for Fibre Channel traffic over Ethernet. The PAUSE mechanism allows a receiver to send a PAUSE frame to a sender when its ingress buffer is full or close to full, instructing the sender to stop transmitting for a specified period of time. This prevents packet loss due to buffer overflow at the receiver. However, the PAUSE mechanism also introduces latency and jitter, which can affect the performance of FCoE applications. Therefore, the receiver must provision sufficient ingress buffer to accommodate the following two sets of data12:

• Frames that were processed and transmitted by the transmitter before the PAUSE frame left the sender. These frames are already on the wire and cannot be stopped by the PAUSE frame. They will arrive at the receiver and consume ingress buffer space.
• Frames that were sent on the link but not yet received. These frames are also on the wire and will arrive at the receiver after the PAUSE frame. They will also consume ingress buffer space.

The amount of ingress buffer required depends on the link speed, the link distance, and the PAUSE duration. The receiver must ensure that the ingress buffer can hold at least twice the link distance worth of data, plus some margin for safety3. For example, if the link speed is 10 Gbps, the link distance is 10 km, and the PAUSE duration is 100 microseconds, the receiver must have at least 25 MB of ingress buffer for each FCoE virtual lane4.

Two capabilities of the Cisco Network Assurance Engine are that it validates that devices comply with network security policies and that it predicts the impact of changes to the network. The Cisco Network Assurance Engine is a software solution that uses mathematical modeling and verification techniques to continuously analyze the state and configuration of the data center network. It can validate that the network devices are compliant with the intended security policies, such as access control lists, firewall rules, and encryption standards. It can also predict the impact of planned or unplanned changes to the network, such as software upgrades, configuration changes, or device failures, and provide proactive recommendations to avoid or resolve issues. The Cisco Network Assurance Engine helps to ensure that the network is always operating as intended and aligned with the business objectives. References :=

FCoE (Fibre Channel over Ethernet) is a technology that allows Fibre Channel traffic to be encapsulated and transported over Ethernet networks. FCoE requires the use of FCFs (Fibre Channel Forwarders), which are devices that act as bridges between the FCoE and Fibre Channel domains. FCFs can be configured with a priority value that determines their preference for connecting to CNAs (Converged Network Adapters), which are devices that support both Ethernet and Fibre Channel protocols. The priority value ranges from 0 to 1024, with 0 being the lowest and 1024 being the highest. To configure an MDS switch as the best switch to connect by the CNAs in the fabric, the fcoe fcf-priority 1024 command should be applied. This gives the switch the highest priority and makes it the most preferred FCF for the CNAs.

 Option D and C are the correct policies that must be configured to meet the requirements. A Maintenance Policy specifies how the changes are applied when a service profile is associated or disassociated with a server or when an updated service profile is applied to a server. A Power Control Policy allows users to select how Cisco UCS Manager should restore power to the servers in a chassis after the chassis loses power. References:

 Option D is the correct statement about the Deployment Immediacy for VMM domains associated to EPGs when the APIC EPG Resolution Immediacy is set to “Immediate”. This means that the policy is pushed to the hardware as soon as the leaf switch is booted, regardless of whether there are any VMs in the EPG or not. This ensures that the policy is ready to be enforced as soon as a VM is created or moved into the EPG. References:

 When a VLAN is added to a trunk and it does not appear on the vNIC of an associated server, it typically indicates that the vNIC template is not updating as it should to reflect changes. By changing the template type of Trunk-A to an updating template, any changes made to the trunk configuration, such as adding a new VLAN, will be dynamically applied to all vNICs associated with that template. This action will allow the newly added VLAN to be included in the vNIC configuration without the need to manually update each vNIC or recreate the templates.

References := This recommendation aligns with best practices for managing vNIC templates in Cisco UCS environments, where updating templates are used to ensure changes propagate automatically to all associated instances

The command checkpoint file before_maintenance is used to create a checkpoint of the current running configuration with the specified file name. The command rollback running-config file before_maintenance atomic ensures that the rollback of the checkpoint to the running configuration only occurs if there are no errors during the process. This is essential for maintaining the stability of the switch during maintenance operations.

Ansible is known for its agentless architecture, which means it does not require any software to be installed on the target devices. It can manage the devices using SSH, which is typically available on most Linux servers. This makes it suitable for scenarios where the operations team needs to update configurations across a large number of devices without direct access1.

References := For more information on how Ansible works and its capabilities for network automation, you can refer to the official Ansible documentation and resources available on the Ansible website1. These resources provide detailed guidance on using Ansible for network automation tasks, including configuration updates and management.

The import function is available for all configuration, system configuration, and logical configuration files. You can perform an import while the system is up and running. An import operation modifies information on the management plane only. Some modifications caused by an import operation, such as a change to a vNIC assigned to a server, can cause a server reboot or other operations that disrupt traffic. https://www.cisco.com/en/US/docs/unified_computi ng/ucs/sw/gui/config/guide/141/UCSM_GUI_Configuration_Guide_141_chapter43.html#concept_D789E16C90724AEFB99D565574E45AD5

 In the provided configuration, the commands are used to configure a Fibre Channel interface on a Cisco Nexus 5000 Series switch. The “interface fc2/3” command is used to enter the interface configuration mode for the specified Fibre Channel interface. The “switchport mode sd” command configures the Fibre Channel interface for synchronization distribution (SD). SD is a feature that allows the distribution of clocking information through the network to synchronize different parts of a system.

References: The Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course provides detailed information on configuring Fibre Channel interfaces, including synchronization distribution12. Additional resources can be found in Cisco’s data center certification materials3

Option C meets the security requirements for the Cisco UCS C-Series Server. It disables unencrypted communication by enabling HTTPS, sets the session timeout to 900 seconds (15 minutes), redirects HTTP to HTTPS to divert unencrypted traffic, and changes the SSH port to a nondefault value (2022), which is essential for CLI-based management.

References := For further details on securing Cisco UCS C-Series Servers, refer to the Cisco UCS C-Series Servers Integrated Management Controller CLI Configuration Guide, which provides instructions on configuring service profiles, security settings, and management access.

The command ‘aaa authentication login default fallback error local’ is used to ensure that if RADIUS servers are unreachable, the system will fall back to using the local user database for SSH access to the Cisco MDS 9000 Series Switch.

A full state configuration backup in Cisco UCS Manager includes a snapshot of the entire system, which is stored as a binary file. This backup type is ideal for disaster recovery as it can restore or rebuild the configuration on the original fabric interconnect or recreate the configuration on a different fabric interconnect. It is important to note that this backup type cannot be used for an import but is specifically designed for system restoration.

Options D and E are the correct firmware packages that are included in the Cisco UCS C-Series Rack-Mount UCS-Managed Server Software bundle. The bundle contains the firmware for the CIMC (Cisco Integrated Management Controller) and the BIOS (Basic Input/Output System) of the server. The other options are either not part of the bundle or not applicable for the server. References:

 To establish adjacency to the remote peer by using multicast, the engineer needs to configure the otv data-group command with a multicast address range that is unique for each site. This command specifies the multicast group that is used to send and receive OTV data traffic. To enable OTV advertisements for VLAN 100 to the other site, the engineer needs to configure the otv extend-vlan command with the VLAN number. This command specifies which VLANs are extended across the overlay network. References:

 To make a capture task persistent after a reboot, the command sequence in Option C should be used. This typically involves enabling the service to start at boot time using systemctl enable and then starting the service with systemctl start. This ensures that the capture task will automatically resume after the system is rebooted4

The last packet indicates a DHCP Release message, which is sent by the client to the DHCP server to release the assigned IP address. This is typically done when the client no longer requires the IP address, or before the client shuts down to ensure the IP address can be reassigned. The packet capture showing a DHCP Release message confirms that the client is informing the DHCP server that it is releasing its current IP address.

References := For further understanding of DHCP operations and troubleshooting connectivity issues, the Cisco Data Center Core Technologies source book provides detailed explanations. Additionally, Cisco’s official documentation and resources on their website offer extensive guidance on managing and troubleshooting DHCP in Cisco environments. These materials are essential for network engineers working with Cisco Nexus series switches and dealing with DHCP-related issues.

 The command that completes the EEM script configuration for saving a copy of the running configuration to bootflash on a Cisco Nexus 9000 Series Switch is running-config. This command is used in the EEM applet to specify the source of the configuration file that needs to be copied. The complete command in the EEM applet would be action 1.0 cli command "copy running-config bootflash:/current-config.txt". This command will save the running configuration to a file named current-config.txt in the bootflash when the specified event occurs, which is when a user saves the configuration.

Graphical user interface, text, application Description automatically generated

 Option A is the correct configuration set to create an EEM script that saves a copy of the running configuration on bootflash and writes a message to syslog when a user saves the configuration to a Cisco Nexus switch. The EEM script uses the event manager applet command to define the applet name and the event that triggers the script. In this case, the event is the CLI pattern “copy running-config startup-config” which matches the command that a user would use to save the configuration. The action commands specify the commands that the script will execute when the event occurs. In this case, the script will copy the running configuration to bootflash, write a message to syslog, and exit. The other options have incorrect commands or syntax errors. For example, option B uses the wrong event keyword, option C uses the wrong action keyword, and option D uses the wrong file name. References:

 IP ARP suppression (D) is used in VXLAN EVPN environments to minimize flooding. When enabled, it allows the local switch to respond to ARP requests for known hosts, thus preventing the need to flood these requests across the entire network segment1. This feature is particularly useful in scenarios where there is a large amount of ARP traffic that could potentially lead to flooding, as it reduces unnecessary broadcast traffic by handling ARP resolution within the control plane2.

References: The role and configuration of IP ARP suppression in VXLAN EVPN environments are detailed in Cisco’s documentation and best practice guides for VXLAN BGP EVPN

The ‘best-effort’ command is used when implementing a configuration checkpoint on a Cisco Nexus 9000 Series Switch to ensure that the process skips any existing vPC configuration errors and completes even if there are other configuration errors. This command is suitable for scenarios where it’s critical to proceed with the checkpoint despite errors, allowing the engineer to create a rollback point and address issues without disrupting the entire process.

 The two components that support specific power limits on a Cisco UCS C-Series rack server are the processor and the graphic card. The processor and the graphic card are the two components that consume the most power on a server, and they can be configured to have specific power limits to control the power usage and performance of the server. The power limits can be set using the Cisco Integrated Management Controller (CIMC) web interface or CLI, or using the Cisco UCS Manager if the server is integrated with a Cisco UCS domain. The power limits can be applied to individual processors or graphic cards, or to the entire server. The power limits can help to optimize the power efficiency and thermal management of the server, as well as to prevent power capping or throttling issues. References :=

To meet the deployment requirements for implementing VSANs on a Cisco MDS 9000 Series Switch, the correct steps are to create VSAN 10 in the VSAN database and bind it to the interface fc1/1. This assigns the host on port fc1/1 to VSAN 10. Additionally, enabling VSAN trunking on the Inter-Switch Link (ISL) and allowing VSAN 10 on the ISL ensures that the port channel 10 can pass multiple VSANs, including VSAN 10. This configuration allows for the segregation of traffic and maintains the isolation of different VSANs while still permitting communication across the shared physical infrastructure12.

The network administrator role in Cisco UCS Manager is designed to allow configuration of network-related settings, which includes vHBAs, vNICs, and server port types. This role provides the necessary privileges to manage these components

An ISSU upgrade on the Cisco MDS 9000 Series Switch allows for software updates with minimal impact on the switch’s operation. The control plane remains up during the upgrade, ensuring continuous network operations and service availability. The process is carefully designed to prevent any significant downtime, and any brief disruption is kept well under the 120-second mark1.

The DCNM performance monitoring configuration parameter that must be implemented to achieve the result of triggering events when monitored traffic exceeds the configured percent utilization threshold is the Util% parameter. This parameter allows the administrator to set a utilization threshold as a percentage, which, when exceeded, triggers an event. The requirement to configure a maximum limit of 39860437 bytes directly relates to the statistics collected as a ratio of the total link capacity, which is effectively managed by setting the Util% parameter. This parameter is part of the Performance Manager Configuration Wizard in DCNM, which provides the ability to set up two thresholds that trigger events when the monitored traffic exceeds the percent utilization configured. These thresholds can be set as either Critical or Warning events that are reported on the DCNM-SAN web client Events browser page1.

The Bash script is designed to loop through the available namespaces and output all registered interfaces within the Cisco NX-OS Guest Shell. The correct code snippet to complete the script is option C, ifconfig "$ns". This command will display the network configuration for each namespace, allowing the engineer to view all registered interfaces.

References: The use of ifconfig in conjunction with namespace variables is a common practice in network scripting to retrieve interface information. For more detailed information on scripting in Cisco NX-OS, you can refer to the Cisco Nexus 9000 Series NX-OS Programmability Guide.

Option C is the correct choice. The commands copy sftp://admin@192.168.10.100/backup.cfg bootflash:///backup.cfg vrf management followed by configure replace bootflash:///backup.cfg will copy the backup configuration file from the SFTP server to the switch’s bootflash and then replace the running configuration with the backup file without requiring a restart of the switch. This process is known as configuration replace and is a feature that allows for the replacement of the entire running configuration with a new one provided by the user1.

References: The procedure for performing a configuration replace on Cisco Nexus 9000 Series Switches can be found in the Cisco documentation1. It is important to ensure that the backup configuration file is a valid running configuration file and that the switch has connectivity to the SFTP server through the mgmt0 interface. The configure replace command intelligently calculates the difference between the current running configuration and the user-provided configuration, applying only the necessary changes

 The correct configuration for a unified I/O link that supports both LAN and SAN traffic using a single Ethernet transport is to configure the interface as a trunk port. This allows multiple VLANs (for LAN traffic) and VSANs (for SAN traffic) to coexist on the same physical link. The auto qos trust dscp command ensures that the Quality of Service (QoS) markings are preserved, which is essential for maintaining traffic prioritization across the network.

These resources provide comprehensive guidance on configuring and managing Cisco Nexus and MDS switches in a data center environment.

 During the Install Server Firmware stage of a Firmware Auto Install upgrade through Cisco UCS Manager, the components that are upgraded include the Cisco UCS C-Series Rack-Mount Servers and the Cisco UCS B-Series Blade Servers. This stage uses host firmware packages to upgrade all servers and their components in the Cisco UCS domain. All servers whose service profiles include the selected host firmware packages are upgraded to the firmware versions in the selected software bundles1.

 The configuration in Cisco UCS Manager needs to specify the source of the traffic for the SPAN session. Since the requirement is to monitor the traffic from VSAN 11, selecting VSAN 11 as the source will direct the traffic to the monitoring session. This is consistent with the SPAN session’s purpose, which is to create a copy of the traffic for analysis or monitoring.

References := For more information on configuring SPAN sessions in Cisco UCS Manager, you can refer to the Cisco Data Center Core Technologies study materials and official documentation, which provide guidelines on setting up traffic monitoring solutions within a Cisco data center environment. These resources will offer detailed instructions and best practices for implementing SPAN sessions to monitor VSAN traffic.

 To ensure that vPC and non-vPC switches receive the same STP bridge ID from the upstream vPC switch peers, the engineer must implement the peer-switch feature on the vPC domain. The peer-switch feature allows the two vPC peer switches to act as a single logical switch for STP purposes, and to use the same bridge ID and priority. This way, the downstream switches will see the vPC peer switches as a single STP root, and will not have any STP loops or inconsistencies. The peer-switch feature also improves the convergence time and reduces the number of STP instances required in the network. References :=

Placing all EPGs in the preferred group within a VRF allows for communication between them without the need for additional contracts. This is because the preferred group feature in Cisco ACI allows EPGs within the same VRF to communicate with each other by default, bypassing the need to provide and consume contracts1. This simplifies the configuration process when new EPGs and bridge domains are added, as they inherit this communication capability by being part of the preferred group1.

References := For more information on the implementation of VRFs and the use of the preferred group feature in Cisco ACI, you can refer to the Cisco documentation on “Use vzAny to Automatically Apply Communication Rules to all EPGs in a VRF” and other related resources1. These documents provide detailed guidance on how to configure VRFs and EPGs to achieve seamless communication within the network infrastructure.

Cisco Data Center Network Manager (DCNM) is designed to help manage all NX-OS network deployments, which includes LAN fabrics, SAN fabrics, and IP Fabric for Media (IPFM) networking in the data center. DCNM provides prebuilt templates that can be used to customize fabric deployments, allowing for a more streamlined and efficient setup process. These templates include best-practice policy templates for Easy Fabric Mode and support for Python scripting for more complex policy templates, facilitating the customization and automation of fabric deployments.

Cisco HyperFlex uses the Network File System (NFS) protocol for sharing data among nodes in a VMware vSphere environment. NFS is a distributed file system protocol that allows a user on a client computer to access files over a network in a manner similar to how local storage is accessed. This protocol is commonly used in virtualized environments for ease of data sharing and management12.

References: The use of NFS in Cisco HyperFlex environments is documented in Cisco’s official installation guides and design documents

Option C is the correct command to make an XML backup of Cisco UCS Manager. The command creates a backup file named “all-config9.bak” that contains all system and service profiles configuration. The command also specifies the protocol as SCP (Secure Copy Protocol), which transfers the backup file using an authenticated and encrypted tunnel. References:

The correct command set is Option C, which includes the command fcdomain fcid persistent vsan 120. This command ensures that the Fibre Channel IDs (fcid) are saved across reboots for VSAN 120, meeting the requirement for persistent Fibre Channel IDs. The other commands in Option C are used to set the WWN and fcid as per the given requirements.

References: For a comprehensive explanation, please refer to the “Implementing and Operating Cisco Data Center Core Technologies (DCCOR)” course, which covers the skills and technologies needed to implement data center compute, LAN, and SAN infrastructure, including the management of Fibre Channel IDs

The command in Option D correctly uses a loop to iterate over the range {1…5}, which represents the first five interfaces. The dohost command is used to send commands to the host Cisco Nexus switch from the Guest Shell. The syntax interface eth1/$x and description Server$x within the loop sets the description for each interface eth1/1 to eth1/5 to “Server1” to “Server5” respectively.

Here’s the command from Option D formatted for clarity:

[guestshell@guestshell ~]$ for x in {1..5}; do

dohost "conf t" ;

interface eth1/$x;

description Server$x;

done

This command will configure the description for each of the first five Ethernet interfaces with the respective server number as part of the description.

Network-attached storage (NAS) is a solution that provides remote and direct file-level access to users and systems. NAS devices are connected to the network and offer shared storage space for files and data. Users and systems can access the files using standard protocols such as NFS or SMB. NAS devices can also offer features such as backup, replication, and security.

In Cisco ACI, a virtual Port Channel (vPC) allows links that are physically connected to two different ACI leaf nodes to appear as a single port channel to a third device. When configuring vPCs in ACI, you do not need to create multiple interface policy groups for each vPC. Instead, you create a single vPC interface policy group that can be applied to multiple vPCs. This is because the fabric itself serves as the multi-chassis trunk (MCT), and peer reachability is managed through the fabric, not through physical peer-links. Therefore, for the scenario described, where two vPCs are created from leaf switches A and B, only one vPC interface policy group is required.

 Option C is the correct attribute to use to assign the servers to different microsegments based on their VM names. By doing this, IT security can enforce policies that isolate production from development database servers existing in the same EPG and IP subnet. This can be achieved by using the microsegmentation feature of Cisco ACI, which allows granular control over the communication between endpoints within an EPG. References:

The method that a network engineer must use to upgrade the BIOS firmware of a Cisco UCS standalone C-Series rack-mount server is to use the Cisco host upgrade utility. The Cisco host upgrade utility is a tool that allows the network engineer to upgrade the firmware of various components of the server, such as the BIOS, the CIMC, the RAID controller, and the network adapter. The Cisco host upgrade utility can be downloaded from the Cisco website and run from a bootable USB drive or CD-ROM. The Cisco host upgrade utility provides a graphical user interface that guides the network engineer through the firmware upgrade process, and allows the network engineer to select the firmware versions and the components to be upgraded. References :=

When deploying a Cisco HyperFlex edge with a pair of switches, the minimum number of interfaces in trunk mode required on each HX node is two 10/25GE ports3. References := Cisco HyperFlex Edge Deployment Guide, Release 5.0(x)3.

 To allow Layer 2 connectivity between Host 1 in VLAN 100 located in DataCenter 1 and Host 2 in VLAN 200 located in DataCenter 2, the correct OTV VLAN mapping configuration is option C. This configuration involves mapping VLAN 100 to VLAN 200 across the OTV overlay so that hosts in these separate VLANs can communicate as if they were in the same Layer 2 domain. The VLAN mapping is achieved by configuring the OTV edge devices in both data centers to associate the VLANs with each other.
