NEW QUESTION # 69
The Central Processing Unit (CPU) is the computer's computing and control core. Mainly composed of an arithmetic logic unit (ALU) and a controller, it reads and executes data according to instructions.
- A. TRUE
- B. FALSE
Answer: A
Explanation:
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.

NEW QUESTION # 75
On FusionAccess, when creating a full copy, QuickPrep, or linked clone template, the template must be added to a domain.
- A. FALSE
- B. TRUE
Answer: A
Explanation:
Comprehensive and Detailed Explanation (HCIA-Cloud Computing aligned):
In FusionAccess, templates must not be joined to a domain.
HCIA-Cloud Computing materials specify that:
* Templates are created in a workgroup environment.
* Domain joining is performed during desktop provisioning, not at the template stage.
* Joining a template to a domain can cause conflicts such as duplicate computer accounts.
Therefore, the statement is FALSE.
NEW QUESTION # 76
There are two types of virtual switches. FusionCompute uses ___, which can be distributed on different physical hosts and configured in a unified manner using the virtualization management tool. (Enter the abbreviation.)
Answer:
Explanation:
DVS
According to the Huawei HCIA-Cloud Computing curriculum, specifically the "Network Technology Basics" and "FusionCompute Network Virtualization" modules, there are two primary types of virtual switches in a virtualized environment:
the standard virtual switch and the Distributed Virtual Switch (DVS).
The DVS is the advanced switching model used within Huawei's FusionCompute to provide a consistent and simplified networking environment for Virtual Machines (VMs) across a cluster of physical hosts.The statement correctly identifies the DVS as the component that can be distributed across multiple physical hosts.
In a traditional setup, each host would have its own local virtual switch that must be managed independently, leading to configuration inconsistencies and operational complexity as the data center scales. However, the DVS functions as a single, logical switch that spans all the hosts within a cluster. This allows administrators to perform "unified configuration" from theVRM (Virtual Resource Management)portal. When a port group or a VLAN is configured on a DVS, that configuration is automatically pushed to all theCNA (Computing Node Agent)nodes associated with that switch.This architecture is essential for advanced cloud features likeVM Live Migration. Because the DVS maintains a consistent network state (such as port IDs, VLAN tags, and security policies) across different physical servers, a VM can move from one host to another without losing its network connection or requiring a reconfiguration of its virtual NIC. The DVS effectively decouples the virtual network from the physical network hardware, allowing the logical network to "follow" the VM wherever it goes. In the Huawei ecosystem, the DVS is the cornerstone of Software-Defined Networking (SDN) at the computing layer, ensuring that large-scale virtualized networks are both manageable and resilient.

Answer: B
NEW QUESTION # 86
In Huawei FusionCompute, which of the following functions enables virtual machines (VMs) to be migrated between CNA hosts with different CPU models?
- A. Cluster Guest NUMA policy
- B. Cluster I/O ring adaptation
- C. Cluster HANA optimization
- D. Cluster IMC policy
Answer: D
Explanation:
In FusionCompute, VM live migration between hosts withdifferent CPU modelsrequires CPU instruction compatibility. Huawei provides theIMC (Instruction Masking Compatibility) policyat the cluster level to address this issue.
TheCluster IMC policymasks advanced CPU instruction sets so that VMs only see a common subset of CPU features supported by all hosts in the cluster. This ensures that a VM can migrate safely between CNA hosts with different CPU generations or models without encountering instruction incompatibility errors.
Other options are unrelated:
* I/O ring adaptationfocuses on I/O optimization.
* HANA optimizationis specific to SAP HANA workloads.
* Guest NUMA policyoptimizes memory access, not CPU compatibility.
Therefore, the correct answer isCluster IMC policy.
NEW QUESTION # 87
Data packets in the cloud computing virtual network need to be routed and forwarded through routers in the physical network.
- A. False
- B. True
Answer: A
NEW QUESTION # 88
FusionCompute adopts hardware-assisted virtualization technology to reduce memory virtualization overhead.
- A. TRUE
- B. FALSE
Answer: A
Explanation:
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.
