H13-511_V5.5 Exam Questions & Answers

Comprehensive and Detailed Explanation (HCIA--Cloud Computing aligned):

In FusionCompute architecture, the host OS refers to the operating system running on the physical compute node.

The Compute Node Agent (CNA) is the component deployed on the physical server. It integrates the host operating system and hypervisor, directly managing hardware resources and providing virtualization services.

Linux VM (A) refers to the guest OS running inside a virtual machine.

VRM (B) is the centralized management component.

VNA (C) is responsible for virtual networking services.

Therefore, the host OS runs within the CNA, making D the correct answer.

Comprehensive and Detailed Explanation (HCIA--Cloud Computing aligned):

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

Huawei recommends deploying the VRM 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 are not recommended for VRM system deployment. HCIA materials clearly emphasize that VRM should rely on local disks to guarantee management availability.

Therefore, the correct answer is Local storage.

Comprehensive and Detailed Explanation (HCIA--Cloud Computing aligned):

Huawei FusionCompute provides a comprehensive virtualization platform with advanced management and scheduling capabilities.

A is true. FusionCompute supports dynamic resource adjustment, including CPU and memory scaling, helping applications adapt to workload changes.

B is true. FusionCompute supports x86 and Arm architectures, multiple storage backends, and mainstream operating systems such as Linux and Windows, ensuring broad application compatibility.

C is true. SLA policies allow administrators to define priorities for virtual machines, ensuring that critical applications receive sufficient resources.

D is true. FusionCompute supports automatic VM migration (such as DRS-like features) based on predefined policies to balance workloads and optimize system performance.

All listed statements correctly describe FusionCompute capabilities.

Comprehensive and Detailed Explanation (HCIA--Cloud Computing aligned):

All four statements accurately describe key initialization and configuration principles of FusionAccess:

A is true: When Windows AD is interconnected and local authentication is disabled, AD authentication has higher priority than LiteAS.

B is true: vAG/vLB deployment requires proper WI cluster configuration to enable access services.

C is true: To avoid backup data loss caused by infrastructure failures, external FTP backup servers are recommended in production networks.

D is true: When a License supports multiple charging modes, administrators must explicitly choose User Count or Concurrent User Count.

Thus, all options are correct.

Comprehensive and Detailed Explanation (HCIA--Cloud Computing aligned):

Huawei FusionCompute leverages hardware-assisted virtualization technologies such as Intel VT-x, EPT, and AMD-V, which significantly reduce the overhead associated with CPU and memory virtualization.

Memory virtualization traditionally involved complex software-based address translation, which introduced performance overhead. With hardware-assisted features such as Extended Page Tables (EPT), memory mapping is handled directly by the CPU, improving efficiency and performance.

This approach is explicitly highlighted in HCIA--Cloud Computing materials as a key reason why FusionCompute delivers near-native performance for virtual machines.

Therefore, the statement is TRUE.
