The highlighted component on the Cisco I/O module is the chassisconnections LED, which indicates the status of connectivity between the I/O module and the chassis.

In the exhibit, the orange arrow points to asmall rectangular LED indicatorlocated to the left side of the I/O module (Cisco UCS-IOM-2304). This specific LED isnot aligned with the ports, fans, or screws, which helps identify it correctly.

Chassis connections LED (B)is responsible for indicating thestatus of uplink/downlink communicationbetween the I/O module and the chassis.

Greenusually indicates a healthy link.

Amberoroffmay indicate a problem or no connection.

Why the other answers are incorrect:

A. Captive screw→ These are at the far corners, not where the arrow points.

C. Fan module LED→ This IOM doesn’t have user-visible fan LEDs atthe front face.

D. Fixed port→ These are the large rectangular SFP ports clearly visible in the middle, not near the arrow.

This identification is important whentroubleshooting chassis-to-IOM connectivityor verifyingmodule status LEDsduring field maintenance.

In theInfrastructure as a Service (IaaS)model, the cloud provider is responsible for managing and maintaining the underlying infrastructure components, including:

Networking: The cloud provider handles all aspects of network configuration, hardware, and virtual networking.

Storage: The cloud provider supplies and manages the physical and virtual storage infrastructure required to support the consumer’s data needs.

The customer is responsible for managing:

Operating Systems

Applications

Data

This model offers flexibility while shifting infrastructure maintenance responsibilities to the service provider.

Bundle modesimplifies the installation and operation of Cisco IOS XE Software by using a monolithic image file. In thismode, the switch runs directly from the bundled image, eliminating the need to manage individual software packages. This approach is straightforward and reduces complexity, making it suitable for environments where simplicity is a priority.​

However, it's important to note that:​

Bundle mode may result in slower boot times compared to Install mode.

It does not support the independent installation or upgrade of individual packages.

Thepackages.conffile is not utilized in Bundle mode; it's specific toInstall mode.​

Asubnet maskis a 32-bit number used in IP networking to divide an IP address into network and host portions. This division is crucial for routing traffic within and between networks. The subnet mask works in tandem with the IP address to identify which part of the address refers to the network and which part refers to the host. This distinction allows for efficient IP address allocation and routing.​

For example, in the IP address 192.168.1.10 with a subnet mask of 255.255.255.0, the first three octets (192.168.1) represent the network portion, while the last octet (10) identifies the specific host within that network.​

Cisco NX-OSis the operating system specifically developed forCisco Nexus series switches, which are widely used in modern data centers. NX-OS is optimized forscalability, high availability, and virtualization features.

It differs from IOS and IOS XE (used in traditional routers and switches) and IOS XR (used in carrier-grade platforms). NX-OS includes advanced features such as Virtual Port Channels (vPC), FabricPath, and integrated Layer 2/3 capabilities tailored for data center networks.

Apre-service checklistis a procedural step followed before replacing an endpoint. Its primary purpose is toconfirm that all resources, tools,documentation, and personnel are in placeto execute the replacement efficiently and without delays.

It helps avoid service interruptions and ensures a smooth replacement by ensuring that every necessary component and action is accounted for ahead of time.

In a Cisco Nexus switch withdual power supplies, the recommended method is toconnect each power supply to a separate power source(Option C). This ensures power redundancy and fault tolerance.

If one power source fails (e.g., due to a power outage or circuit failure), the switch can continue operating uninterrupted using the second power source. Connecting both to a single source (Option D) defeats the purpose of redundancy.

TheUCS Fabric Interconnectis the central management and communication hub of theCisco UCS (Unified Computing System)environment. It integrates compute, network, and storage access into a unified system.

Fabric Interconnects:

Manage all servers and I/O modules connected to the UCS domain

Provide connectivity and are the point of integration with the Cisco UCSManager

Offer high-availability and centralized policy management

Other options like the Nexus or MDS switches do not serve this unified management function in a UCS deployment.
