H13-511_V5.5 Exam Dumps - Huawei HCIA-Cloud Computing Questions and Answers

In the HCIA–Cloud Computing virtualization domain, the hypervisor is the core software layer responsible for abstracting and managing physical compute resources and enabling multiple virtual machines to run on a single physical host.

A hypervisor is also commonly referred to as a Virtual Machine Monitor (VMM). The VMM directly manages CPU scheduling, memory allocation, and virtual device access for guest operating systems.

The other options are not equivalent to a hypervisor:

VRM (Virtual Resource Management) refers to centralized management components used in platforms like FusionCompute.

VNM (Virtual Network Management) relates to virtual networking control.

VPM (Virtual Power or Performance Management) is not a hypervisor concept in HCIA materials.

Therefore, the correct answer is VMM.

In the Huawei HCIA-Cloud Computing curriculum, specifically within the "Storage Technology Basics" module, the comparison between centralized and distributed storage is a fundamental topic. Statement A is FALSE because it incorrectly suggests that reading data from multiple independent devices simultaneously has a negative impact on read efficiency. According to the official technical documentation, the opposite is true: distributed storage utilizes a parallel I/O architecture. When a data request is made in a distributed system (such as Huawei FusionStorage), the system retrieves data blocks from multiple nodes at once. This concurrency significantly improves the overall throughput and read/write speed of the system rather than "affecting" it negatively.

The other statements are technically accurate according to Huawei standards. Centralized storage (Statement B) is indeed known for its simpler deployment and reliance on traditional RAID levels (0, 1, 5, 6, 10) to protect against disk failures within a single controller or enclosure. Statement C correctly outlines the taxonomy of centralized storage, distinguishing between file-level NAS and block-level SAN (which includes both FC and IP variants). Statement D accurately describes the core value proposition of distributed storage: its ability to scale out by adding more commodity hardware nodes. By spreading the storage load across a cluster, distributed storage eliminates the performance bottlenecks often found in centralized controllers and enhances system reliability through multi-replica or erasure coding mechanisms. In Huawei’s cloud solutions, distributed storage is the preferred architecture for large-scale resource pools because it ensures that performance scales linearly with capacity, providing the high availability and efficiency required for modern virtualized data centers.

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.

1-D, 2-C, 3-B, 4-A

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.

As defined in the "Network Technology Basics" module of the HCIA-Cloud Computing training, a router is a Layer 3 (Network Layer) device responsible for interconnecting different network segments and selecting the optimal path for data packets. To perform this function, the router maintains and manages a Routing Table. This table is the "map" of the network that the router uses to make forwarding decisions. Every entry in the routing table typically includes several key parameters: the destination network address, the subnet mask, the protocol (how the route was learned, such as Static, OSPF, or BGP), the preference value, the cost (metric), and the next-hop address or outbound interface.

When a router receives an IP packet, it examines the destination IP address and performs a lookup in its routing table to find the most specific match (longest match rule). If a matching entry is found, the router encapsulates the packet into a new frame and sends it toward the next hop. If no match is found and no default route exists, the packet is discarded. This process is fundamental to the operation of a Cloud Data Center where multiple Virtual Private Clouds (VPCs) and subnets must communicate through virtual or physical routers.

While a switch manages a MAC address table to forward frames at Layer 2, and a host manages an ARP table to map IP addresses to MAC addresses, only the routing table provides the cross-network path intelligence required for routing. In Huawei’s virtualization solutions, virtual routers within the software-defined networking (SDN) layer use these same logic principles to ensure that traffic between virtual machines in different subnets is directed efficiently to the correct destination. Proper management of the routing table is therefore the cornerstone of network reachability in cloud environments.

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

FusionAccess OA security architecture adoptszone-based isolation(red, yellow, green zones).

Each zone islogically and physically isolated

Each zone has itsown FusionAccess system

Data is not allowed to flow freely between zones

OptionBis false because it incorrectly states that data can be transmitted between zones. The other statements correctly reflect FusionAccess OA security and integration characteristics.

In the HCIA–Cloud Computing syllabus, Linux command-line operations are part of theOperating System Basicsdomain. Viewing file contents is one of the most common Linux administration tasks.

Theless (A)command is used to view file contents page by page. It supports forward and backward scrolling and searching, making it suitable for viewing large files. HCIA materials often recommend less as a preferred file-viewing tool.

Themore (B)command is an earlier paging command that displays file contents one screen at a time. Although it has fewer features than less, it is still a valid file-viewing command.

Thecat (D)command is used to display the entire content of a file directly to standard output. It is commonly used for viewing small files or concatenating files.

Thevim (C)command is primarily atext editor, not a file-viewing command. While it can open and display files, its main purpose is editing rather than viewing, which is how HCIA differentiates it.

Therefore, the correct answers areA, B, and D.

According to the HCIA–Cloud Computing FusionAccess module, different desktop types are designed for different business workloads.

New media operationstypically involve tasks such as video editing, image processing, animation rendering, and real-time previewing. These workloads aregraphics-intensiveand require high-performance GPU acceleration.

Design-oriented GPU graphics cloud desktopsare specifically designed to support:

GPU pass-through or vGPU acceleration

High-resolution displays

Graphics rendering and multimedia processing

Professional applications used in media, design, and creative industries

Secure office desktops focus on data protection rather than performance. General office desktops target routine tasks such as documents and emails. Public terminal desktops are designed for shared access and lightweight workloads.

Therefore, the most suitable desktop type for new media operations isDesign-oriented GPU graphics cloud desktops.

In the official Huawei HCIA-Cloud Computing documentation, specifically the "FusionAccess Security" module, the system is described as having a multi-layered security architecture. These four access management policies are the primary tools used to control entry into the virtual desktop environment.

MAC address-based control (A)allows administrators to bind specific users or groups to authorized hardware devices. This ensures that even if a password is compromised, the user can only log in from a company-issued terminal.Time-based control (B)functions as a whitelist; it defines a "valid window" (e.g., 08:00 to 18:00) during which desktop access is permitted. Outside of these hours, the system rejects connection attempts, which is critical for managing contractors or ensuring compliance with labor regulations.

IP address-based control (C)is highly flexible, supporting both blacklists (to block known malicious ranges) and whitelists (to allow only local office subnets). Administrators can define these rules for individual IPs or entire CIDR blocks. Finally,Certificate-based control (D)provides the highest level of identity assurance. Unlike the other policies which can be granular, certificate authentication is typically a global system setting in the ITA/HDC configuration. When enabled, every client must present a valid digital certificate issued by a trusted Certificate Authority (CA) before they are even prompted for a username and password.

By combining these policies, Huawei FusionAccess creates a "Zero Trust" style environment where access is granted based on the user's identity, their physical device, their location (IP), and the time of day. Understanding how to configure these policies in theITA (IT Adapter)portal is a key requirement for the HCIA-Cloud Computing certification and essential for maintaining a secure enterprise desktop cloud.

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.
