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

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

VLAN technology is a fundamental topic in HCIA–Cloud Computing, especially for cloud network isolation and segmentation.

Option A is false. A trunk link is designed to carry traffic from multiple VLANs using VLAN tags (802.1Q). Untagged traffic typically belongs to a native VLAN, not multiple VLANs.

Option B is false. A hybrid interface can be used to connect a switch to a server. Hybrid interfaces support both tagged and untagged VLAN traffic and are commonly used in server and virtualization scenarios.

Option C is true. Trunk interfaces are primarily used to connect switch-to-switch links, allowing multiple VLANs to pass between switches.

Option D is false. Access interfaces are designed to connect end devices (such as PCs or printers) and carry traffic for only one VLAN, not for switch interconnections.

Therefore, the false statements are A, B, and D.

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

FusionAccess supports different desktop pool types, each with specific provisioning rules:

Static Pool supports both linked clone and full copy desktops → A is true.

Quick provisioning allows flexible desktop assignment strategies → B is true.

VM grouping is finalized during desktop assignment → C is true.

Dynamic Pool typically supports linked clone desktops only, because desktops are created and destroyed dynamically.

Therefore, statement D is false.

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.

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

In Active Directory (AD), domains and organizational units (OUs) serve different purposes.

A is true. Both domains and OUs can contain AD objects such as users, computers, and groups.

B is true. Authentication is performed at the domain level. Users log in to a domain, not to an OU.

C is true. Group Policy Objects (GPOs) can be applied at both the domain level and the OU level.

D is false. An OU can exist inside a domain, but a domain cannot exist inside an OU. Domains are top-level logical boundaries.

Therefore, the correct answers are A, B, and C.

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

In FusionAccess, full copy desktops are created by completely copying the template into an independent virtual machine. After the VM is created, it no longer depends on the template.

According to HCIA–Cloud Computing materials:

Modifying or deleting a full copy template does not affect already provisioned desktops.

Only linked clone desktops depend on the template and snapshot chain.

Therefore, the statement is FALSE.

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

RAID technology is a key topic in the Storage Technology Basics domain of HCIA–Cloud Computing. Different RAID levels provide varying balances of performance, capacity, and fault tolerance.

RAID 0 (A) uses data striping across multiple disks to improve read/write performance but provides no data redundancy. This statement is correct.

RAID 1 (C) uses disk mirroring, where identical data is written to two disks, ensuring high data reliability. This statement is correct.

RAID 5 (D) uses distributed parity across disks, allowing data recovery if one disk fails. This is also correct.

RAID 6 (B) is the false statement. RAID 6 does not use mirroring. Instead, it uses dual parity, allowing the system to tolerate the failure of two disks simultaneously.

Therefore, option B is incorrect and is the false statement.

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

The HCIA–Cloud Computing syllabus defines clear terminology for virtualization components.

The Guest OS is the operating system installed and running inside a virtual machine. It operates as if it were running on physical hardware, but all hardware access is abstracted by the hypervisor.

The hypervisor (A) is the virtualization layer that manages physical resources and virtual machines.

The host OS (B) is the operating system running on the physical server (in hosted virtualization models).

The host machine (D) refers to the physical server itself.

Therefore, the correct answer is Guest OS.

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

CPU virtualization is a fundamental concept in HCIA–Cloud Computing and includes multiple implementation methods.

Option A is correct. CPU virtualization is commonly categorized into full virtualization, paravirtualization, and hardware-assisted virtualization.

Option B is correct. Full virtualization allows guest operating systems to run without modification, which ensures high compatibility and portability across different platforms.

Option C is correct in the HCIA context. Paravirtualization requires modifications to the guest OS kernel, which historically limited support primarily to open-source operating systems.

Option D is false. Hardware-assisted virtualization explicitly requires CPU support, such as Intel VT-x or AMD-V. Without these features, hardware-assisted virtualization cannot function.

Therefore, the false statement is D.

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

FusionAccess consists of multiple components, each with different roles and data persistence requirements.

WI (Web Interface) stores configuration and user access information and supports backup.

VLB (Virtual Load Balancer) maintains configuration data that can be backed up.

vAG (Virtual Access Gateway) also stores configuration-related data that supports backup and recovery.

The License component, however, is not backed up as configuration or system data. Licensing information is typically re-imported or reactivated during recovery rather than restored from backup.

Therefore, the component that does not have backup data is License.

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

In FusionCompute architecture, CNA and VRM have clearly defined deployment models.

Option A is false. CNA is deployed only on physical servers (compute nodes). It is responsible for interacting directly with hardware resources and cannot run inside a VM.

Option B is true. When VRM is deployed on physical servers, active and standby VRM nodes must be installed on separate physical servers to ensure high availability.

Option C is true. When VRM is deployed on virtual machines, the active and standby VRM VMs must be placed on different hosts within the management cluster to avoid single points of failure.

Option D is true. VRM supports deployment on either physical servers or virtual machines, providing flexible management options.

Therefore, the correct answers are B, C, and D.
