Pass the Huawei HCIA-Cloud Computing H13-511_V5.5 Questions and answers with CertsForce

According to the HCIA–Cloud Computing documentation forFusionCompute installation, theVirtual Resource Management (VRM)node plays a critical role in managing virtualization resources such as hosts, virtual machines, and clusters.

Huawei recommends deploying theVRM system disk on local storage. The main reasons are reliability and independence. Local storage ensures that VRM can still start and function even if shared storage services (such as SAN or NAS) encounter issues. This improves management plane stability and reduces dependency on external storage systems.

Although IP SAN, FC SAN, and NAS are commonly used for VM data storage, they arenot recommended for VRM system deployment. HCIA materials clearly emphasize that VRM should rely onlocal disksto guarantee management availability.

Therefore, the correct answer isLocal storage.

In the Huawei FusionCompute architecture, network traffic is logically divided into specialized "planes" to ensure security, isolation, and optimal performance. TheBMC plane(Baseboard Management Controller) is dedicated to hardware-level management. It utilizes a dedicated network port on the physical host toenable remote access to the BMC system, allowing administrators to perform out-of-band tasks such as power control, BIOS configuration, and hardware health monitoring regardless of the OS state.

TheManagement planeis the communication backbone for the virtualization platform. It is used by the Virtual Resource Management (VRM) and Computing Node Agent (CNA) tomanage all nodes in a unified manner. All nodes in the cluster communicate on this plane to report resource status and receive management instructions. TheStorage planeis specifically reserved for data transmission between the compute hosts and the back-end storage infrastructure. This is theplane on which hosts communicate with storage units(such as LUNs or shared folders) to handle VM disk I/O.

TheService planeis the network segmentused by user VMsfor their actual service traffic. It carries the data produced and consumed by the applications running inside the virtual machines. Huawei documentation mandates the isolation of these planes—typically via VLANs—to prevent a "broadcast storm" or high data load in one plane (like Storage) from impacting the accessibility of the Management plane or the performance of user services.

In FusionAccess architecture:

HDC (Huawei Desktop Controller) is responsible for desktop lifecycle management, including provisioning logic, policy enforcement, and resource validation.

During VM creation, HDC verifies whether the specified VM group and desktop group exist and whether configurations are valid.

Other components:

GaussDB stores metadata.

HDA runs inside desktops.

HDP is a display protocol.

Thus, the correct answer is HDC.

From the HCIA–Cloud Computing learning scope, the core advantages of using cloud services (including Huawei Cloud) are typically tied toagility, elasticity, and cost efficiency.

Quick service deployment and rollout (A)is a standard cloud advantage because cloud providers offer ready-to-use services, templates, and automated provisioning. This allows businesses—especially startups—to launch environments in minutes instead of purchasing, shipping, installing, and configuring physical infrastructure.

Flexible resource scaling (B)is one of the most emphasized cloud characteristics. Cloud resources can be scaledup/downbased on demand (elasticity), helping companies handle traffic spikes or reduce capacity during off-peak times without long procurement cycles.

Reduced hardware costs (D)is also a common advantage because the company avoids large upfront capital expenses (CapEx) for servers, storage, and networking. Instead, cloud typically follows apay-as-you-gomodel (OpEx), which is ideal for early-stage businesses with uncertain growth.

However,Higher hardware performance with the same configuration (C)isnotan inherent cloud advantage. If the virtual machine configuration (CPU, memory, disk type) is the same, cloud does not automatically guarantee higher performance than equivalent hardware elsewhere. Performance depends on factors such as underlying physical host load, storage type, network conditions, and service class—so “higher performance with the same configuration” is not a guaranteed benefit and therefore is the incorrect “advantage.”

Important note (transparency):I can format and answer based onHCIA domain concepts, but Icannot provide “exact extracts” from Huawei official copyrighted documentsin a verbatim way.

In the "Virtualization Basics" section of the Huawei HCIA-Cloud Computing training material, the taxonomy of virtualization components is strictly defined. Statement C is FALSE because the virtualization software layer is technically called the Hypervisor or Virtual Machine Monitor (VMM), not the "Host OS." While a "Host OS" exists in Type-2 (hosted) virtualization (where the hypervisor runs as an application on top of an existing OS like Windows or Linux), the software layer that actually performs the resource abstraction and logical partitioning is the Hypervisor itself.

The other definitions are central to Huawei's technical documentation. AGuest OS(Statement A) is indeed the operating system—such as Windows Server or Ubuntu—that is installed inside a Virtual Machine. It is "unaware" that it is running on virtual hardware. TheHost Machine(Statement B) refers to the underlying physical server (e.g., a Huawei FusionServer Pro) that provides the actual CPU, RAM, and physical NICs. Finally, aGuest Machine(Statement D) is a synonym for a Virtual Machine (VM), representing the logical container that houses the Guest OS and applications.

In a Type-1 virtualization architecture (like HuaweiFusionCompute), the Hypervisor (CNA) sits directly on the hardware. In this scenario, there is no "Host OS" at all, further proving why statement C is incorrect. The Hypervisor is responsible for trapping "privileged instructions" from the Guest OS and translating them into actions on the physical hardware. Correctly identifying these roles—Host Machine, Hypervisor, and Guest VM—is a prerequisite for understanding more advanced cloud features like Resource Clusters and Distributed Resource Scheduling (DRS).

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.

====================

FusionAccess defines clear behaviors for desktop service adjustment:

Bis true. After reassignment, the systemautomatically starts the desktop, and a short wait time is required before user login.

Dis true. When a desktop assigned to a single user is unassigned, the systemautomatically shuts it downto save resources.

Ais false. Desktops assigned to multiple users or desktop groupscan be reassignedafter being unassigned.

Cis false. After unassignment, a desktop can beassigned to a different user, not only the original one.

Thus, the correct answers areB and D.

Virtualization Technology

Description

KVM

Does not perform any hardware simulation.

Xen

Domain0 is the first VM to start on the host.

QEMU

Can simulate the implementation of an entire VM, including the CPU, memory, I/O device, USB, and NIC.

Libvirt

Can manage multiple virtualization platforms.

Huawei's technical materials differentiate between these technologies based on their specific roles within the virtualization ecosystem.KVM (Kernel-based Virtual Machine)is an open-source module within the Linux kernel. While it provides the core virtualization capabilities for CPU and memory, it is defined in the HCIA curriculum as a technology thatdoes not perform hardware simulationitself. Instead, it typically relies on hardware-assisted virtualization or integrates with other tools to handle I/O operations.

Xenis a Type-1 hypervisor that operates directly on the hardware. A unique feature of the Xen architecture isDomain0, which is a privileged virtual machine that starts first and provides the management environment and drivers for other guest VMs (DomainU). In contrast,QEMUis a pure software-based emulator. It is powerful because itcan simulate an entire VM, including all peripherals like the CPU, NIC, and USB. However, because it relies on software simulation, its performance is lower than hardware-assisted technologies unless it is used as a backend for KVM.

Finally,Libvirtserves as the universal management layer. It is a set of open-source library functions and APIs that allow administrators tomanage multiple virtualization platforms(including KVM, Xen, and VMware) using a standardized command set. It provides transparency to upper-layer management software by abstracting the complexities of the underlying hypervisor. Understanding how these technologies interact—such as KVM utilizing Libvirt for management and QEMU for I/O—is a critical learning objective for candidates preparing for the Huawei H13-511 exam.

RAID 0

➡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

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

RAID 5

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

RAID 10

➡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 documentation, the core definition of virtualization centers on the abstraction of physical resources. The essence of virtualization technology is precisely the transformation of physical, hardware-based resources—such as CPUs, memory, network interface cards, and storage disks—into virtualized, logical entities. This process is facilitated by a software layer known as the Hypervisor or Virtual Machine Monitor (VMM). By creating this abstraction layer, virtualization effectively achieves the "decoupling" of the software environment (the Operating System and applications) from the underlying physical hardware.

This decoupling is a revolutionary shift from traditional computing architectures where an Operating System was tied to specific hardware drivers and physical configurations. In a virtualized environment, a Virtual Machine (VM) perceives a set of standardized, logical hardware components provided by the Hypervisor. Because the software is no longer bound to the physical machine, it gains significant mobility and flexibility. For example, in Huawei’s FusionCompute platform, this decoupling allows for features such as Live Migration, where a running VM can be moved from one physical host to another without any service interruption. This is possible because the VM's "logical" hardware remains consistent even as the "physical" host changes.

Furthermore, this transformation from physical to logical enables better resource utilization through overcommitment and sharing. Multiple logical servers can run on a single physical server, each isolated from the others. This fundamental shift is what provides the agility, scalability, and efficiency required for Cloud Computing. Without the decoupling provided by virtualization, the rapid provisioning and elastic resource scaling that define cloud services would be impossible to achieve. Therefore, virtualization serves as the indispensable technical foundation upon which all other cloud services and management layers are built within the Huawei ICT ecosystem.
