H13-511_V5.5 Exam Dumps - HCIA-Cloud Computing V5.5 Exam

According to the Huawei HCIA-Cloud Computing training materials, the statement is FALSE. In a Distributed Virtual Switch (DVS), a port group is a management object used to define common attributes for a collection of virtual ports. These attributes include VLAN settings, security policies, and Quality of Service (QoS) parameters. When an administrator configures a priority (such as an 802.1p priority tag) within a port group, that configuration applies to the entire port group, meaning all VMs connected to that group share the same policy.

The system does not allow for the setting of individual "priorities" for each specific member port (VM port) directly within the port group configuration. Instead, the port group ensures consistency across the virtual network. If different VMs required different priorities, they would typically be placed into different port groups, each with its own specific QoS and VLAN configuration.

It is important to distinguish this fromUplink Groups. In an uplink group (which connects the DVS to physical network cards), administratorscanset priorities or active/standby states for physical member ports (NICs) to control traffic flow and redundancy. However, for the virtual ports used by VMs within a standard port group, the logic is based on uniform policy enforcement. Huawei's documentation emphasizes that port groups are designed to simplify management by allowing the administrator to configure a policy once and have it apply to all associated VM NICs, thereby reducing the risk of manual configuration errors on a per-port basis.

In Huawei FusionAccess, user authentication and authorization for Windows desktops are typically integrated withActive Directory (AD). During VM template creation, the option“Configure user login”is used to specify who is allowed to log in to the virtual desktop.

According to the HCIA–Cloud Computing FusionAccess service provisioning process, this option is selected whenAD group membersare intended to access the VM. FusionAccess then uses AD-based authentication to control desktop login permissions, ensuring centralized identity management and consistent security policies.

Therefore, the correct word shown on the GUI and required to complete the sentence isAD.

In HCIA–Cloud Computing (Operating System Basics), Linux network interface configuration is a foundational skill, and openEuler follows the standard Red Hat–style network configuration syntax.

To configure a static IP address, the parameter BOOTPROTO must be set to static. This tells the operating system not to request an IP address from a DHCP server and instead use the manually configured values such as IPADDR and NETMASK.

To ensure that the NIC is automatically activated when the system boots, the parameter ONBOOT must be set to yes. If ONBOOT is set to no, the interface will remain down after boot and must be manually started.

Therefore, the completed and correct configuration is:

BOOTPROTO=static

ONBOOT=yes

BOOTPROTO=static → Uses a fixed IP address

ONBOOT=yes → Enables automatic startup at system boot

This configuration exactly matches HCIA–Cloud Computing requirements for static IP configuration on openEuler.

This statement is TRUE and covers two fundamental concepts within the Huawei HCIA-Cloud Computing curriculum: resource locality and High Availability (HA).

First, the statement addresses the constraint ofresource locality. In the current architecture of Huawei FusionCompute (and most mainstream virtualization platforms), a single Virtual Machine (VM) cannot "span" its core compute resources (vCPU and RAM) across multiple physical hosts simultaneously. For instance, if a physical host has 128GB of RAM, you cannot create a single VM with 256GB of RAM, because that VM’s memory address space must be mapped to the physical DIMMs of a single physical server to maintain performance and synchronization. Therefore, the maximum specifications of a VM are always bounded by the physical hardware limits of a single host within the cluster.

Second, the statement accurately describes theHigh Availability (HA)function. While a running VM is tied to one host, cloud computing overcomes this physical dependency through cluster-level management. When theVRM (Virtual Resource Management)node detects that a physical host has malfunctioned (via heartbeat loss), it triggers the HA policy. Since the VM’s disk files are stored on shared storage (like a SAN or NAS), the system "assigns" the VM to a different healthy host in the same cluster. The VM is then automatically restarted on that new host, which provides the necessary CPU and memory resources to resume services.

This combination of strict host-level resource allocation for execution and cluster-level flexibility for recovery is what allows Huawei’s cloud solutions to provide stable, enterprise-grade infrastructure. Understanding that compute resources are provided by a "single host" at runtime, but protected by the "cluster" during a failure, is a core objective of the HCIA-Cloud Computing certification.

In OpenStack:

Swiftprovidesobject storage, designed for storing unstructured data such as images, videos, and backups.

Cinderprovidesblock storage, which is used by virtual machines as virtual disks.

Since Swift doesnotprovide block storage, the statement isFALSE.

RAID 0

âž¡Multiple disks are combined to form a large-capacity storage device. This RAID level supports data striping to improve read and write speed, but does not provide data verification or redundancy backup.

RAID 1

âž¡Data on one disk is mirrored to another disk to provide complete redundancy backup.

RAID 5

âž¡Parity data is distributed on all disks in the array. Write operations can be performed on different disks at the same time.

RAID 10

âž¡Mirror backup is performed for each disk, and then the disks are combined to form a storage device, providing high read and write performance in addition to redundancy backup.

In the official Huawei HCIA-Cloud Computing curriculum, specifically in the module "Huawei Virtualization Platform Management and Usage," the process for connecting hosts to storage is strictly defined. For storage types that rely on an Ethernet network (IP-based storage), such as IP SAN (iSCSI), NAS (NFS), and Huawei Distributed Block Storage (FusionStorage), the system requires the configuration of "Storage Ports" on each host. A storage port is a logical interface created on a physical NIC or a bond of NICs on a CNA (Computing Node Agent) node.

The reason this step is mandatory is that these storage protocols require an IP address to establish a session between the host (Initiator) and the storage device (Target). Without adding a storage port and assigning it a valid IP address within the storage network's segment, the host cannot communicate with the storage controllers. For IP SAN, this port is used to discover LUNs; for NAS, it is used to mount shared folders; and for Distributed Block Storage, it is used by the VNA (Virtual Node Agent) to communicate with the storage pool.

In contrast, forFC SANstorage, "storage ports" in the IP sense are not required because the Fibre Channel protocol uses World Wide Names (WWNs) on the Host Bus Adapters (HBAs) for identification. The Huawei documentation emphasizes that the storage network (Storage Plane) should be logically or physically isolated from the management and service planes to ensure high performance and security. Therefore, configuring storage ports with dedicated IPs is a prerequisite for creating a datastore on any IP-based storage backend in FusionCompute.
