According to the Huawei HCIA-Cloud Computing technical guidelines, storage is categorized by its connection method and the protocol used to access data. Direct Attached Storage (DAS) is the most basic form, where storage devices are connected directly to a single server via an internal bus or external cable. While simple, it lacks the scalability and resource-sharing capabilities required for modern cloud data centers. Network Attached Storage (NAS) provides file-level access over a standard IP network, typically using protocols like NFS or CIFS, allowing multiple clients to share a central pool of files over a local area network.

The Storage Area Network (SAN) is a specialized, high-speed network that provides block-level access to storage, making it appear to the operating system as a locally attached disk. In Huawei’s virtualization solutions, SANs are the preferred choice for high-performance clusters and features like VM Live Migration. As the statement correctly identifies, SANs are primarily divided into two types based on the transport protocol used: Fibre Channel (FC) SANs and IP SANs. FC SANs utilize dedicated fiber-optic cables, FC switches, and Host Bus Adapters (HBAs) to transmit data using the Fibre Channel protocol, offering extremely high reliability and minimal latency. Conversely, IP SANs utilize standard Ethernet infrastructure and the iSCSI protocol to encapsulate SCSI commands into IP packets. This allows for lower costs and easier management by leveraging existing Ethernet knowledge. Understanding these distinctions is crucial for the HCIA exam, as the choice between FC and IP SAN directly impacts the deployment architecture and performance characteristics of Huawei's FusionCompute and FusionAccess solutions in an enterprise environment.

According to the Huawei HCIA-Cloud Computing curriculum, statement C is FALSE regarding the architecture of a datastore. While a datastore is indeed a logical repository similar to a file system, it does not "combine storage devices of different types" into a single unified model. In FusionCompute, a datastore has a strict 1-to-1 relationship with its underlying storage resource. For example, a datastore created on an FC SAN LUN is separate from a datastore created on an NFS share or a local disk. You cannot merge a LUN from a SAN and a folder from a NAS into a single "Datastore" entity. Each datastore is formatted with a specific file system (like VIMS for block storage or NFS for file storage) that is native to that specific storage type.

The other statements represent the core principles of storage virtualization in the Huawei ecosystem. Statement A is true; LUNs from Huawei's distributed block storage (FusionStorage) are presented to hosts as block devices and can then be initialized as VIMS datastores. Statement B is a fundamental definition ofVirtualized Storage: the hypervisor uses a cluster file system (VIMS) to hide the complexities of the hardware, allowing each VM to exist simply as a set of files (configuration files, disk files like .vhd, and log files) inside a directory.

Statement D is also correct; storage virtualization significantly improves utilization through technologies likeThin Provisioning. In a traditional environment, if you allocate 100GB to a server, that space is "locked." In a virtualized environment with thin provisioning, the datastore only consumes the actual physical space being used by the data, allowing administrators to "over-allocate" storage and maximize the efficiency of their physical disk arrays.

In the official Huawei ICT Academy curriculum, virtualization is defined as the core enabling technology that transforms physical hardware into logical, manageable resources. This process involves the introduction of a virtualization layer, often referred to as a Hypervisor or Virtual Machine Monitor (VMM), which sits between the physical hardware and the operating systems. The statement is TRUE because it accurately captures the three primary characteristics of virtualization as defined in Huawei’s technical documentation: Simulation, Isolation, and Sharing.

Simulationrefers to the ability of the Hypervisor to present a consistent set of virtual hardware (CPU, Memory, I/O) to the Guest Operating System, regardless of the underlying physical vendor. This allows software to run in an environment it perceives as dedicated physical hardware.Isolationis a critical security and stability feature; it ensures that if one Virtual Machine (VM) crashes or is compromised, it does not affect the operation of other VMs on the same physical host. Each VM operates in its own logical container with dedicated boundaries. Finally,Sharingallows multiple VMs to occupy a single physical server simultaneously, maximizing resource utilization.

Before virtualization, the "one-server-one-application" model led to massive resource wastage (often using only 5%–15% of capacity). By creating alogical representationof physical resources, virtualization enablesCloud Computingto achieve its goal of multi-tenancy and elastic scaling. In Huawei’sFusionComputearchitecture, this is implemented through theCNA (Computing Node Agent), which uses the Galax88 engine to virtualize CPU and memory resources and theVNA (Virtual Node Agent)for management, effectively decoupling the software from the hardware constraints.

According to the Huawei HCIA-Cloud Computing technical documentation, the term Hypervisor is used interchangeably with Virtual Machine Monitor (VMM). The VMM is the core software component that creates the virtualization layer between the physical hardware and the Guest Operating Systems. Its primary responsibility is to abstract physical resources (CPU, Memory, I/O) and present them as logical, virtualized resources to the Virtual Machines. The VMM manages the execution of the Guest OS and ensures that different VMs remain isolated from one another on the same physical host.8

In the Huawei ecosystem, specifically within theFusionComputearchitecture, the hypervisor functionality is provided by theCNA (Computing Node Agent)node using the UVP (Universal Virtualization Platform) engine.9While "Hypervisor" is a general industry term, "VMM" specifically describes the role of monitoring and mediating the hardware requests from virtualized guests.10The other options provided are incorrect in this context:VRM (Virtual Resource Management)is the centralized management node that coordinates multiple CNA nodes but is not the hypervisor itself.VNA (Virtual Node Agent)is an agent running on the CNA node that communicates with the VRM, but it does not perform the actual hardware virtualization.

The VMM performs critical tasks such as instruction trapping and emulation.11When a Guest OS attempts to execute a "privileged instruction" that would normally interact directly with the hardware, the VMM intercepts it and executes it safely on behalf of the VM.12This ensures that a single VM cannot crash the entire physical host or access the data of another VM. Understanding that the Hypervisor and VMM are the same entity is fundamental to mastering the taxonomy of virtualization used in Huawei's ICT training and exams.

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

HDP usesintelligent bitmap classification:

Text and fine detailsuselossless compressionto ensure clarity and readability.

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

This adaptive compression strategy allows FusionAccess to deliversmooth user experienceeven in limited bandwidth environments, which is a highlighted advantage in HCIA materials.

Therefore, the statement isTRUE.

According to the Huawei HCIA-Cloud Computing documentation, specifically within the "Planning and Deployment of FusionAccess" module, the network architecture of a cloud data center is divided into distinct planes to ensure security, isolation, and efficient management. In a FusionAccess deployment, infrastructure virtual machines (VMs)—which include critical components such as the ITA (IT Adapter), HDC (Huawei Desktop Controller), WI (Web Interface), and the GaussDB database—are considered the "management brain" of the desktop cloud solution.

TheManagement planeis specifically designed to facilitate communication between management systems and all nodes within the cloud environment. In the provided scenario, the network segment192.168.10.0/24(VLAN 10) is designated as the FusionCompute Management plane. Huawei's official best practices dictate that Linux infrastructure VMs must be deployed on this plane to allow them to communicate directly with theVirtual Resource Management (VRM)node and theComputing Node Agent (CNA)hosts. This placement ensures that management traffic for desktop provisioning and resource orchestration remains isolated from general user traffic and heavy storage data flows.

In contrast, theService plane(192.168.30.0/24) is intended for the traffic of standard user applications, while theService desktopsegment (192.168.108.0/22) is reserved for the end-user virtual desktops themselves. Placing infrastructure VMs on theStorage plane(192.168.20.0/24) would be technically incorrect, as it is strictly dedicated to disk I/O and would not provide the necessary logical path to the management portal. Therefore, selecting network segment B ensures that infrastructure components are securely positioned to manage the desktop lifecycle while maintaining high availability and administrative accessibility.

The HCIA–Cloud Computing syllabus explains that routers are responsible forinter-network communicationand packet forwarding based onIP addresses. In the TCP/IP reference model, this function corresponds to theNetwork layer.

Routers analyze the destination IP address of a packet and use routing tables and routing protocols to determine thebest pathfor forwarding the packet to its destination. This behavior is distinct from switches, which forward frames based on MAC addresses at the data link layer.

TheData link layer (A)is associated with switches, theTransport layer (D)handles end-to-end communication (such as TCP and UDP), and theApplication layer (C)provides services to applications.

Therefore, according to HCIA–Cloud Computing network fundamentals, the correct answer isNetwork layer.

According to the Huawei HCIA-Cloud Computing documentation, FusionAccess application policies are critical for tailoring the virtual desktop experience to specific security and performance requirements. The Huawei Desktop Protocol (HDP) management interface allows administrators to configure granular controls over data flow, display quality, and session behavior.

For Scenario 1, setting Clipboard Redirection to "Client to Server" ensures a one-way data flow. This allows users to copy text or files from their local physical client into the virtual machine (VM) while preventing the extraction of data from the VM back to the local device, thus protecting sensitive corporate information. In Scenario 2, the Display Policy Grade determines the balance between visual fidelity and network consumption. Grade 5 is the highest setting, designed for high-performance networks (25 Mbit/s or higher), and is optimized for server-side video decoding to provide the best possible playback quality.

Scenario 3 addresses security during periods of inactivity. By enabling the "Automatic Screen Lock" under the Session policy, the system monitors user input and automatically secures the desktop if no activity is detected within the specified interval (such as 10 minutes), preventing unauthorized access to an unattended terminal. Finally, Scenario 4 utilizes File Redirection to control external hardware access. By setting this policy to "Read-only" and enabling "Client Removable Driver," users can view and open files stored on their local USB flash drives within the VM environment but are strictly prohibited from saving or modifying any data back onto those physical devices. These configurations demonstrate the robustness of Huawei’s VDI policy engine in balancing user productivity with stringent security protocols.

According to the Huawei HCIA-Cloud Computing curriculum regarding Open Source Virtualization, statement D is FALSE. Libvirt is famously an open-source toolkit and API, licensed under the LGPL. It was specifically designed to provide a stable, long-term abstraction layer for managing different virtualization technologies. It is not a proprietary or "closed-source" product. In fact, its open nature is what allowed it to become the industry standard for managing Linux-based hypervisors.

The other statements accurately describe Libvirt's role in a cloud environment. As noted in statement A, Libvirt is "hypervisor-agnostic," meaning it can manage multiple types of virtualization, including KVM, Xen, QEMU, and even LXC containers. This allows management tools to use a single set of commands regardless of the underlying technology. Statement B is correct because Libvirt provides bindings for numerous programming languages, such as Python, C, and Java, enabling developers to automate VM lifecycle management (start, stop, migrate, snapshot) directly through code. Statement C is also true; Libvirt is essentially a collection of library functions and a daemon (libvirtd) that higher-level management platforms, such as Huawei'sFusionComputeor the open-sourceOpenStack, invoke to communicate with the hardware.

In Huawei's virtualization architecture, Libvirt acts as a crucial middle layer. By using the virsh command-line tool (which is part of the Libvirt package), administrators can perform complex VM operations without needing to understand the specific, low-level command syntax of each different hypervisor. Understanding that Libvirt is open-source and provides this universal management interface is a key learning point for the HCIA exam.

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

VM live migration in FusionCompute has several mandatory prerequisites.

Ais required because live migration applies only torunning VMs.

Bis required to ensure uninterrupted network connectivity during migration.

Dis required because both source and target hosts must access the same datastore to migrate VM disks seamlessly.

IMC policy (C)isnot mandatoryfor live migration. It is requiredonly when hosts have different CPU models. If hosts use compatible CPUs, live migration can proceed without configuring IMC.

Therefore, the correct answer isC.
