Huawei HCIA-Cloud Computing V5.5 H13-511_V5.5 Exam Questions

Answer : A

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

According to the HCIA--Cloud Computing curriculum under Server Basics, the CPU is defined as the core component responsible for computation and control within a computer system. The CPU executes program instructions and coordinates the operation of all other hardware components.

The CPU is primarily composed of two main functional units:

Arithmetic Logic Unit (ALU): Responsible for performing arithmetic operations (such as addition and subtraction) and logical operations (such as comparisons and logical AND/OR).

Control Unit (Controller): Responsible for fetching instructions from memory, decoding them, and controlling the execution process by issuing control signals to other components.

The CPU operates based on the fetch--decode--execute cycle, which is a fundamental concept emphasized in HCIA learning materials. During this process, the CPU reads instructions and related data from memory, processes them, and produces results according to the instruction set architecture.

Because the statement accurately describes the role, composition, and working principle of the CPU as defined in Huawei's HCIA--Cloud Computing documentation, it is correct.

Answer : B

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

In FusionAccess deployment, vAG (Virtual Access Gateway) and vLB (Virtual Load Balancer) rely on internal account authentication and synchronization to maintain high availability (HA) status.

Changing the following passwords can directly affect HA synchronization:

root password for vAG/vLB (D)

gandalf account password for vAG/vLB (C)

root password for HDC (A), which may disrupt management communication

However, the ITA portal login password (B) is related only to user or administrator portal access and does not participate in HA synchronization mechanisms.

Therefore, changing the ITA portal login password is not a cause of abnormal HA status.

Answer : A, B

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

Bare VM creation rules in FusionAccess are strict to ensure template consistency and successful provisioning:

A is true: The system disk must use Common configuration mode, not thin provisioning.

B is true: For linked-clone bare VMs, NICs are added after template creation, during desktop provisioning.

C is false: Bare VMs should use management-plane networking, not user service-plane DVS/port groups.

D is false: Thin provisioning is not allowed for the system disk of a bare VM.

Therefore, the correct answers are A and B.

Answer : A

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

Huawei Desktop Protocol (HDP) is a proprietary protocol optimized for cloud desktop scenarios and is a key topic in the FusionAccess learning scope.

HDP uses intelligent bitmap classification:

Text and fine details use lossless compression to ensure clarity and readability.

Images, videos, and nonsensitive graphics use lossy compression, which significantly reduces bandwidth consumption while maintaining acceptable visual quality.

This adaptive compression strategy allows FusionAccess to deliver smooth user experience even in limited bandwidth environments, which is a highlighted advantage in HCIA materials.

Therefore, the statement is TRUE.

Answer : A, B

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

In AD, OUs and user groups are both used for organizing and managing resources, but they differ in function.

A is true. Both OUs and user groups are AD objects.

B is true. An OU can contain multiple types of AD objects, including users, computers, printers, and shared resources.

C is false. Group policies cannot be directly applied to user groups; they are applied to domains, sites, or OUs.

D is false. A user group can contain users, computers, and even other groups, not only user accounts.

Thus, the correct answers are A and B.

Answer : B

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

Huawei FusionAccess is a mature cloud desktop (VDI) solution with broad access capabilities and architecture support.

Options A, C, and D are all correct according to HCIA--Cloud Computing materials.

Option B is false. Although FusionAccess uses HDP (Huawei Desktop Protocol) and supports high-resolution displays (including 4K), HDP is not open source. It is a Huawei proprietary protocol optimized for cloud desktop scenarios.

Therefore, the false statement is B.

Answer : B

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

This statement is incorrect based on HCIA--Cloud Computing virtualization concepts.

First, KVM is not a pure paravirtualization technology. It is a hardware-assisted full virtualization solution that relies on CPU virtualization extensions. While KVM can use paravirtualized drivers (such as Virtio) to improve performance, its core architecture is hardware-assisted virtualization.

Second, KVM supports device I/O virtualization. Using technologies such as Virtio, KVM provides efficient virtual network and storage devices. This allows virtual machines to achieve near-native I/O performance, which is a key feature emphasized in HCIA training.

Because the statement incorrectly classifies KVM and wrongly claims that it cannot virtualize device I/O, the correct answer is FALSE.
