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

According to the Huawei HCIA-Cloud Computing training materials, the statement is FALSE. In a Distributed Virtual Switch (DVS), a port group is a management object used to define common attributes for a collection of virtual ports. These attributes include VLAN settings, security policies, and Quality of Service (QoS) parameters. When an administrator configures a priority (such as an 802.1p priority tag) within a port group, that configuration applies to the entire port group, meaning all VMs connected to that group share the same policy.

The system does not allow for the setting of individual "priorities" for each specific member port (VM port) directly within the port group configuration. Instead, the port group ensures consistency across the virtual network. If different VMs required different priorities, they would typically be placed into different port groups, each with its own specific QoS and VLAN configuration.

It is important to distinguish this fromUplink Groups. In an uplink group (which connects the DVS to physical network cards), administratorscanset priorities or active/standby states for physical member ports (NICs) to control traffic flow and redundancy. However, for the virtual ports used by VMs within a standard port group, the logic is based on uniform policy enforcement. Huawei's documentation emphasizes that port groups are designed to simplify management by allowing the administrator to configure a policy once and have it apply to all associated VM NICs, thereby reducing the risk of manual configuration errors on a per-port basis.

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

As covered in the "Cloud Computing Trends" and "Huawei Cloud Solutions" modules of the HCIA curriculum, OpenStack and FusionCompute occupy different layers of the cloud stack. Statement A is correct: OpenStack is a global open-source project maintained by a community, whereas FusionCompute is Huawei’s proprietary commercial virtualization platform (hypervisor).4

Statement B captures a fundamental technical difference. OpenStack is anorchestratoror "Cloud OS"; it lacks an internal hypervisor and must rely on external technologies (like KVM, Xen, or FusionCompute itself) to perform the actual virtualization. In contrast, FusionCompute is a standalonevirtualization suitethat includes the CNA (hypervisor) and VRM (management), allowing it to directly pool and manage physical hardware resources.

Statement C highlights the broader scope of OpenStack, which is designed to manage heterogeneous resources, including Bare Metal (Ironic) and Containers (Zun/Magnum). FusionCompute is a specialized tool primarily focused on Virtual Machines (VMs). Finally, Statement D refers to theMulti-tenancymodel. OpenStack was built for public and large private clouds, using "Projects" and "Tenants" to strictly isolate resources and billing between different organizations. FusionCompute is a lower-level resource manager that focuses on "Clusters" and "Resource Pools" rather than the complex tenant-based isolation logic found in high-level cloud platforms. In the Huawei ecosystem, FusionCompute often serves as the "Computing" component underneath a largerHuawei Cloud Stackor OpenStack-based solution, illustrating how these two technologies complement each other in a modern data center.

As detailed in the Huawei HCIA-Cloud Computing training material regarding FusionAccess Service Provisioning, the statement is TRUE. Huawei FusionAccess is designed to support complex enterprise environments, including multi-domain architectures. This is particularly relevant for large corporations that have acquired other companies or have organized their IT infrastructure into a forest of multiple Active Directory (AD) domains.

FusionAccess achieves this by establishingTrust Relationshipsbetween the "Management Domain" (where the infrastructure components like HDC and ITA are located) and the "User Domains" (where the desktop users' accounts are stored). When trust is correctly configured between AD domains, theHDC (Huawei Desktop Controller)can query and authenticate users across these boundaries. For instance, a user from marketing.huawei.com and another from research.huawei.com can both log into the same Web Interface (WI) and access their respective virtual desktops.

During the service provisioning process, the administrator adds the various domains to the FusionAccess management system. When a user logs in, they specify their domain prefix (e.g., DOMAIN_A\username), and the system routes the authentication request to the appropriate Domain Controller. This multi-domain support is critical forMulti-tenancyand large-scale enterprise consolidation. It allows a single, unified FusionAccess platform to serve multiple organizational units without requiring all users to be migrated into a single, massive AD domain. This logical separation is a key feature taught in the HCIA curriculum to demonstrate the scalability and flexibility of Huawei's virtual desktop solution.

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

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

OptionsA,C, andDare all correct according to HCIA–Cloud Computing materials.

OptionBis false. Although FusionAccess usesHDP (Huawei Desktop Protocol)and supports high-resolution displays (including 4K),HDP is not open source. It is aHuawei proprietary protocoloptimized for cloud desktop scenarios.

Therefore, the false statement isB.

As detailed in the Huawei FusionAccess documentation for the HCIA curriculum, the Huawei Desktop Protocol (HDP) is designed to optimize the user experience in Virtual Desktop Infrastructure (VDI). Statement A is correct: HDP features "Intelligent identification of video data."8 The protocol can automatically distinguish between standard GDI (Graphics Device Interface) desktop elements and active video streams.9 When video is detected, HDP switches to specialized compression algorithms (such as H.264 or H.265) to ensure efficient encoding and reduced bandwidth consumption.

Statement B is also a verified function. HDP employsDynamic Frame Rate Adjustment.10By monitoring the network quality (latency and packet loss) in real-time, the protocol can adjust the frame rate (e.g., from 60fps down to 30fps or lower) to maintain a smooth, jitter-free playback experience even on unstable or low-bandwidth links. Statement C is true as HDP supports multiple rendering modes. In "Multimedia Redirection," the video stream is decoded on theclientside (using local hardware acceleration), while in other modes, decoding occurs on theserver(VM) with the resulting images sent to the client. This dual-support flexibility ensures compatibility across various terminal types.

Statement D isincorrectbecause of the "maximum of 2K videos" limitation. According to the official HCIA-Cloud Computing V5.5 and FusionAccess technical guides, HDP@Media technology (multimedia redirection) explicitly supports4K UHDvideo playback, not just a maximum of 2K. While D correctly mentions "automatic reconnection" and "dynamic traffic adjustment," the resolution limit is technically outdated for the current Huawei cloud ecosystem. Thus, for the purposes of the HCIA certification, only A, B, and C are fully accurate representations of HDP's high-fidelity audiovisual capabilities.

Emerging Technology

Feature / Application Scenario

Edge computing

The number of street lamps continues to increase, and these street lamps hold billions of cameras and environment sensors, which generate frequent and heavy data for processing, analysis, and storage.

Blockchain

Transparent rules, automatic settlement, and E2E tracking of goods all the way from production to final acceptance make the supply chain trustworthy. Electronic proof of delivery (PoDs) reduces paperwork delays. Smart contracts enable automatic settlement to improve efficiency.

Cloud native

Organizations or enterprises build and run scalable applications in public, private, and hybrid clouds.

According to the Huawei HCIA-Cloud Computing curriculum, emerging technologies like Edge Computing, Blockchain, and Cloud Native are reshaping modern IT infrastructures to handle data more efficiently and securely. In the context ofEdge Computing, the massive proliferation of IoT devices in smart cities—such as billions of cameras and environmental sensors mounted on street lamps—creates a data influx that traditional centralized clouds cannot process in real time without significant latency. Edge computing solves this by moving processing and storage capabilities physically closer to the data sources, allowing for nearly instantaneous response times for critical urban systems like traffic management and public surveillance.

Blockchaintechnology provides a decentralized, distributed ledger that is transformative for global supply chain management. By creating a "single source of truth" that is transparent and immutable, it enables end-to-end (E2E) tracking of goods from production to the final consumer. A core feature is the use ofsmart contracts, which are automated, self-executing rules that trigger settlements and payments immediately upon meeting conditions like electronic proof of delivery (PoD), thereby eliminating intermediaries and reducing paperwork delays.

Finally,Cloud Nativerepresents an architectural approach designed to fully exploit the cloud computing model. The official definition from the Cloud Native Computing Foundation (CNCF) states that these technologies "empower organizations to build and run scalable applications in modern, dynamic environments such as public, private, and hybrid clouds". By utilizing independent microservices and portable containers, cloud-native applications achieve the high availability, elasticity, and rapid deployment speed required to meet evolving business needs across diverse infrastructure types.

According to the Huawei HCIA-Cloud Computing curriculum, the definition of centralized storage is centered on the unified management of hardware components. The statement is TRUE as it accurately describes the physical architecture of traditional SAN (Storage Area Network) and NAS (Network Attached Storage) systems. In a centralized model, the storage system typically consists of two main parts: the Controller Enclosure and the Disk Enclosure.

The controller enclosure is the "brain" of the storage system. It contains the controllers (usually in a redundant pair for high availability), cache, and interface modules. Its role is to process I/O requests from servers, manage RAID configurations, and handle advanced data features like snapshots or replication. The disk enclosures, on the other hand, are the physical "shelves" that house the actual Hard Disk Drives (HDDs) or Solid State Drives (SSDs). These enclosures are connected to the controller enclosure via high-speed backend cables (such as SAS).

In this centralized architecture, the physical disks are not "visible" to the hosts directly. Instead, the controller abstracts these physical disks into a storage pool and then intoLUNs (Logical Unit Numbers). These LUNs are then mapped to service hosts (servers) via the storage network (FC or IP). This design allows for high performance and centralized management, as administrators can monitor and configure the entire storage resource pool from a single interface (such as Huawei DeviceManager). This is the standard deployment model for mission-critical applications in a Huawei FusionCompute environment, ensuring that storage resources are consolidated, secure, and easily scalable by adding more disk enclosures.

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

As detailed in the Huawei HCIA-Cloud Computing technical documentation, FusionCompute offers a robust suite of resource management functions. Statement A is correct: FusionCompute datastores support multiple file system formats to accommodate different storage backends. VIMS (Virtual Image Management System) is Huawei’s high-performance cluster file system used for SAN storage; NFS is used for Network Attached Storage; and EXT4 is used for local disk virtualization on a single host. This variety allows administrators to build heterogeneous storage pools.

Statement B is also a verified function. FusionCompute supports dynamic resource adjustment. Users can modify memory capacity for both offline VMs (while the VM is stopped) and online VMs (while running). Online memory expansion requires the "Hot Add" feature and Guest OS support, while reduction typically requires the VM to be in a state where the kernel can release the address space. Statement C accurately describes Storage Live Migration. This feature allows a VM's virtual disk files to be moved from one datastore to another (or within the same storage device) while the VM remains running, which is essential for storage maintenance and load balancing.

Statement D is incorrect because of the word "only." While traditional VM live migration (vMotion style) does require shared storage so that both hosts can see the same disk, modern versions of FusionCompute also support Shared-Nothing Live Migration. This technology migrates both the VM's memory state and its disk data simultaneously over the network, allowing a VM to move between hosts that do *not* share a common backend storage. Because D ignores this advanced capability, it is excluded from the list of correct functions in the context of FusionCompute's full feature set.

In the official Huawei HCIA-Cloud Computing curriculum, the TCP/IP and OSI reference models are used to explain how data moves through a network. A standard network switch is categorized as a Data Link Layer (Layer 2) device. While the TCP/IP model typically combines the physical and data link layers into a single "Network Access" layer, Huawei’s technical training often uses the layered approach to clarify device functions. The Data Link Layer is responsible for hardware addressing and the reliable transmission of frames between adjacent nodes.

A switch operates at this layer because its primary function is to forward data based onMAC (Media Access Control) addresses, which are unique hardware identifiers burned into Network Interface Cards (NICs). Unlike a hub, which simply repeats signals to all ports (Physical Layer/Layer 1), a switch is "intelligent." It builds and maintains a MAC Address Table by observing the source MAC addresses of incoming frames. When a frame arrives, the switch checks the destination MAC address against its table to determine the specific physical port to which the destination device is connected. This creates a dedicated "collision domain" for each port, significantly increasing network efficiency.

In the context of Huawei Cloud Computing, understanding that switches work at the Data Link Layer is vital for configuringFusionComputenetworking. The "Distributed Virtual Switch" (DVS) functions exactly like a physical Layer 2 switch; it manages virtual ports and ensures that frames sent by one Virtual Machine reach the correct destination VM or physical uplink based on MAC discovery. While "Layer 3 switches" do exist and can perform routing, the fundamental "switch" referenced in basic networking and the HCIA-Cloud curriculum is defined by its Layer 2 forwarding logic.

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.

In the official Huawei HCIA-Cloud Computing curriculum, specifically within the "Huawei Virtualization Platform Management" module, the lifecycle and resource adjustment of Virtual Machines (VMs) are covered in detail. While virtualization provides significant elasticity, certain physical-to-logical mappings have technical constraints. According to the training materials, while you can add disks or increase the capacity of an existing virtual disk (expansion), disk capacity cannot be reduced once it has been allocated and formatted by the Guest Operating System.

The reason for this limitation is rooted in data integrity. Reducing a disk's size at the virtualization layer (CNA/VIMS) would involve "chopping off" the end of the logical block range. Since the Guest OS manages the file system and may have placed metadata or data at the end of that range, shrinking the disk from the outside would almost certainly result in file system corruption and data loss. Therefore, Huawei FusionCompute does not provide a "shrink" function for virtual disks. If a user needs a smaller disk, they must create a new, smaller disk and migrate the data at the application level.

In contrast, other resources offer more flexibility. NIC quantities (A) can be reduced by deleting a virtual network adapter from the VM configuration. CPU resources (C) and Memory resources (D) can be adjusted in the VM settings; while increasing them is common, they can also be reduced (typically requiring a VM restart to allow the Guest OS to re-initialize the hardware map). This distinction is a key exam point: compute resources are elastic in both directions (with reboot), but storage capacity in FusionCompute is strictly "expand-only" to protect user data.

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

Service Model

Description

Infrastructure as a Service (IaaS)

The cloud platform provides infrastructure (such as servers, storage devices, networks, and virtual resources) and maintains related resources. Users only need to focus on systems and applications.

Platform as a Service (PaaS)

The cloud platform provides infrastructure (such as servers, storage devices, networks, and virtual resources) and application deployment environment (such as operating systems, middleware, and software running environment) and maintains related resources. Users only need to focus on applications and data.

Software as a Service (SaaS)

The cloud platform provides all resources, services, and maintenance. Users only need to use applications.

According to the official Huawei HCIA-Cloud Computing curriculum, cloud services are categorized into three standard models:IaaS, PaaS, and SaaS, distinguished by the boundary of responsibility between the provider and the user.

In theIaaS(Infrastructure as a Service) model, the provider is responsible for the physical and virtualized hardware resources, including compute, networking, and storage. The user retains control over the "system" level, meaning they must install and manage the operating system, middleware, and applications. This model offers the highest level of flexibility and is the foundation for Huawei's FusionCompute services.

PaaS(Platform as a Service) moves the boundary higher. The cloud platform provides not only the infrastructure but also the entire development and deployment environment. This includes the operating system, database management systems, and middleware. The user is relieved of system maintenance and only needs to focus on the "applications and data" layer. This model is ideal for developers who want to deploy software without managing the underlying server stack.

Finally,SaaS(Software as a Service) represents the highest level of abstraction. The provider manages the entire stack, from hardware to the application itself. Users simply access and "use the application" via a web browser or client. The user has no responsibility for maintenance, updates, or infrastructure scaling. Understanding these models is critical for the HCIA exam as it defines how Huawei Cloud Stack delivers different value propositions to enterprise customers.

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.

TheLicensecomponent, however, isnot backed upas configuration or system data. Licensing information is typically re-imported or reactivated during recovery rather than restored from backup.

Therefore, the component that doesnothave backup data isLicense.

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.

According to the Huawei HCIA-Cloud Computing curriculum and the FusionAccess Maintenance Guide, the statement is FALSE. While it is a recommended best practice to restart infrastructure virtual machines (VMs) approximately once every quarter to clear system cache, refresh memory resources, and ensure long-term stability, the method of execution described in the statement is incorrect and dangerous for production environments.

Infrastructure VMs in FusionAccess—such as theWI (Web Interface),HDC (Huawei Desktop Controller),ITA (IT Adapter), andGaussDB (Database)—are the "brains" of the desktop solution. Most of these components are deployed in active/standby or load-balancing pairs to ensure High Availability (HA). If an administrator were to run the reboot command on all Linux infrastructure VMs "at the same time," it would cause a complete service interruption. During this period, users would be unable to log in to their desktops, the management portal would be inaccessible, and active desktop sessions might lose their connection persistence.

The official Huawei documentation mandates astaggered restartapproach. For example, if there are two WI nodes, the administrator should restart the first node, verify it has returned to service, and only then proceed to restart the second node. This ensures that the "Service Plane" remains active at all times. Additionally, restarts should always be performed during off-peak hours to minimize the impact of the brief transition period between active and standby nodes. Therefore, while the frequency (quarterly) is correct, the instruction to restart them all simultaneously contradicts the fundamental principles of high-availability management within the Huawei ICT framework.

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

In Huawei FusionCompute, VIMS is a storage virtualization file system designed specifically for Huawei’s virtualization platform.

Option A is true. VIMS underpins advanced storage features such as thin provisioning, snapshots, and live storage migration, which are core functions in FusionCompute.

Option B is true. VIMS supports multiple backend storage types, including FC SAN, IP SAN, and local disks, offering flexible deployment options.

Option D is true. VIMS is a high-performance cluster file system optimized for virtualized environments and concurrent access.

Option C is false. VIMS is not a universal industry-standard file system. It is a Huawei-specific storage virtualization file system, designed for FusionCompute and not broadly adopted across all vendors.

Thus, the false statement is C.

According to the "Network Technology Basics" chapter of the Huawei HCIA-Cloud Computing training materials, the statement provided is FALSE. The fundamental rule for IPv4 subnet masks is that binary 1s represent the network portion (network ID), while binary 0s represent the host portion (host ID). A subnet mask is a 32-bit value that is used in conjunction with an IP address to determine which segment of the address identifies the network and which segment identifies the specific device or host on that network.

This identification process is performed using a bitwise AND operation. When a computer or router compares an IP address to its subnet mask, the bits that align with the "1s" in the mask are preserved to reveal the network address, while the bits that align with the "0s" are ignored for routing purposes but used to identify the individual host. For example, in a standard Class C subnet mask (255.255.255.0), the first 24 bits are all set to 1. This indicates that the first three octets of the IP address are the network prefix. The remaining 8 bits are set to 0, providing a range for up to 254 usable host addresses.

Understanding this distinction is critical for cloud administrators when planning Virtual Private Clouds (VPC) and subnets within Huawei's cloud infrastructure. If the roles of 1s and 0s were reversed, as suggested in the question, the logic of IP routing and address allocation would fail. The official curriculum emphasizes that the subnet mask must consist of a contiguous block of 1s followed by a block of 0s. The length of the 1s (the prefix length) directly dictates how many subnets can be created and how many hosts each subnet can accommodate.

Technical Rationale

Step 1

Update template

Power on the VM to install the latest OS patches and software updates.

Step 2

Delete user

Remove user profiles and personal data to ensure the master image is clean.

Step 3

Remove VM from domain

Disjoin the VM from the AD domain to prevent Security Identifier (SID) or account name conflicts on new clones.

Step 4

Reset built-in administrator password

Set a secure, standardized baseline credential for the local administrator account.

Step 5

Configure template

Run theHuawei Desktop Preparation Toolto optimize the OS and encapsulate the system.

Step 6

Convert VM into template

Use the management console to officially mark the VM as a read-only template resource.

 Initialization (Steps 1-4):Before a VM can be turned into a "Golden Image," it must be stripped of its unique identity. This includes removing it from anyActive Directory (AD)domain and clearing out specific user accounts. Failing to remove the VM from the domain can lead to "duplicate computer name" errors when new desktops are provisioned from the final template.

 System Encapsulation (Step 5):The "Configure template" phase is often synonymous withSysprepor the Huawei-specific encapsulation process. This step resets the OS clock and generalizations, such as the hardware-dependent drivers, so the image can boot correctly on any host in the cluster.

 Finalization (Step 6):Once converted into a template, the VM is no longer a running instance. It becomes a master file that theITA (IT Adapter)uses for rapid service provisioning.

According to the official Huawei HCIA-Cloud Computing documentation, converting a provisioned full-copy virtual machine (VM) back into a template is a specific administrative workflow used for updating "Golden Images" without starting from a bare VM. The process must follow a logical sequence to ensure that the final template is clean, generalized, and compatible with the FusionAccess management plane.

The workflow begins withStep 1: Update template, which involves powering on the VM to install necessary software patches, security updates, or new applications. Once updated,Step 2: Delete useris performed to remove any cached user profiles, temporary files, or local user data that should not exist in the master image.Step 3: Remove VM from domainis a critical step to ensure that the VM is no longer associated with a specific Active Directory security identifier (SID) or domain account, preventing SID conflicts when the template is later used to provision multiple new desktops.

Following the domain disjunction,Step 4: Reset built-in password of administratoris required to ensure the FusionAccess system can maintain management access via a known, local credential during the subsequent automation phases.Step 5: Configure templateinvolves running theHuawei Desktop Preparation Tool. This tool performs system encapsulation (similar to Sysprep), optimizes the OS for VDI usage, and prepares the Huawei Desktop Agent (HDA). Finally,Step 6: Convert VM into templateis the final action performed in the FusionCompute or FusionAccess management console. This marks the VM as a read-only template resource, ready to be used by the ITA (IT Adapter) for rapid service provisioning.

In the official Huawei FusionAccess maintenance and troubleshooting documentation, High Availability (HA) between the vAG (Virtual Access Gateway) and vLB (Virtual Load Balancer) is maintained through backend synchronization and heartbeat checks. The correct answer is D because changing the ITA portal login password has no technical impact on the background communication between infrastructure VMs. The ITA portal password is the credential used by an administrator to log into the web management interface (https://ITA_IP:8448); it is an application-layer credential stored in the database, not a system-level credential used for inter-component service discovery or HA heartbeats.

In contrast, options A, B, and C can indeed lead to "HA status abnormal." In the Huawei ecosystem, components often communicate using internal system accounts. Specifically, thegandalfaccount is the default account used for the FusionAccess management plane to log in to and manage these components. If an administrator manually changes the gandalf password on the vAG/vLB VM (Option C) without updating the corresponding credentials in the management system, the ITA will lose its ability to query the status of those nodes, resulting in an abnormal HA state.

Furthermore, while the root password (Options A and B) is generally for administrative access, the FusionAccess components are tightly integrated. Changing system-level passwords without using the official Huawei password management tools or updating the service configurations can break the scripts responsible for status reporting and synchronization. Therefore, for the HCIA exam, it is critical to understand that theITA Portal passwordis purely for the user interface and does not affect the technical "plumbing" or HA heartbeats of the underlying virtual appliances.

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

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.

According to the Huawei HCIA-Cloud Computing curriculum, specifically the "FusionAccess Planning and Deployment" section, the statement is TRUE. When an enterprise scales its desktop cloud across multiple regions or deploys separate FusionAccess environments (each with its own ITA/HDC/DB set), there is often a requirement to share a single license pool to optimize costs and management.

In a standard small-scale deployment, the License component is typically co-deployed with theITA (IT Adapter). However, if multiple independent FusionAccess systems (different clusters or management sets) need to draw from the same license file, the License component must be "de-coupled" from any specific ITA anddeployed independentlyas a standalone service. This standalone License Server acts as a centralized repository that tracks the total number of permitted desktop users or VMs. Each FusionAccess system is then configured to point to this central server's IP address.

This independent deployment model ensures that license seats are not "trapped" in one specific system. For example, if System A has 500 licenses but only 200 active users, and System B is at its limit, a centralized license server allows System B to utilize the excess capacity. This flexibility is a core architectural principle in Huawei’s large-scale VDI solutions. During deployment planning, administrators must decide whether to use a local license (co-deployed) or a centralized license (independent). For multi-system environments, the independent deployment is the official Huawei recommendation to ensure proper license reconciliation and to prevent "over-use" or "under-use" of purchased ICT assets across the enterprise.

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

In OpenStack:

Swiftprovidesobject storage, designed for storing unstructured data such as images, videos, and backups.

Cinderprovidesblock storage, which is used by virtual machines as virtual disks.

Since Swift doesnotprovide block storage, the statement isFALSE.

Quick provisioning using alinked clone templateis designed to rapidly deploy desktops while ensuring standardization and automation.

According to HCIA–Cloud Computing FusionAccess service provisioning procedures, the quick provision workflow includes:

Creating the VMbased on the linked clone template and snapshot.

Renaming the VMto meet enterprise naming rules.

Adding the VM to the domain, enabling centralized authentication and policy control.

Associating the VM with a user or user group, which determines desktop assignment and access permissions.

All listed operations are integral steps in the linked clone quick provisioning process. Therefore,all options are correct.

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.

Huawei FusionComputeHigh Availability (HA)is designed to improve service continuity by automatically responding to VM or host failures.

OptionAis true. FusionCompute allows administrators to configuredifferent HA policiesfor virtual machines based on service importance, which aligns with SLA-driven management principles.

OptionCis true. One of the core functions of HA isautomatic VM rebootwhen a virtual machine encounters a failure, ensuring rapid service recovery.

OptionDis true. FusionCompute continuously monitorsCNA host and VM status. If a CNA host fails, HA triggers VM migration or restart on another available host in the same cluster, minimizing downtime.

OptionBis false. Even when usingshared storage, HAdoes not guarantee zero data loss. HA focuses onservice recovery, not data consistency. Data loss may still occur depending on application state and write operations at the time of failure.

Therefore, the false statement isB.

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.

In the official Huawei HCIA-Cloud Computing curriculum, the OS is described as the bridge between hardware and software, with the kernel serving as its most critical component. The statement is TRUE because the kernel acts as the core manager of all physical resources, including the CPU, memory, and I/O devices. When an upper-layer application needs to perform a task—such as reading a file from a disk or sending data over a network—it cannot access the hardware directly. Instead, it must send a request to the kernel through a System Call Interface.

The kernel operates in a protected "Kernel Mode," while applications run in "User Mode." This separation ensures system stability and security. By managing resource scheduling, the kernel ensures that multiple applications can run concurrently without interfering with each other's memory space or crashing the entire system. In a virtualization context, the role of the kernel becomes even more significant. For instance, in Huawei’s KVM-based virtualization, the Linux kernel itself is transformed into a Hypervisor. The kernel's ability to manage CPU and memory is extended to create virtualized versions of these resources for Virtual Machines (VMs).

The Huawei training documentation highlights that the efficiency of the kernel directly impacts the performance of the cloud platform. Because the kernel handles process management, memory allocation, and the file system, any optimization at the kernel level results in better VM density and lower latency for cloud services. Therefore, understanding the kernel's role as both a resource manager and a provider of the system call interface is fundamental for any ICT associate working with Huawei FusionCompute or FusionAccess solutions.

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

In FusionCompute virtual networking, VMs in thesame network segment and same port groupshould be able to communicate normally.

OptionAis a possible cause. Host-based or VM-based firewalls may block traffic between virtual machines.

OptionCis also a possible cause.Security groupscan apply access control rules that isolate VMs, even within the same subnet.

OptionDis a possible cause. Faulty virtual NICs or driver issues can prevent network communication.

OptionBisnota possible cause. If both VM NICs are connected to thesame port group, they should be able to communicate, assuming no other restrictions exist.

Therefore, the correct answer isB.

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.
