Free and Premium Huawei H13-511_V5.5 Dumps Questions Answers

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.

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

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.

In the "Virtualization Basics" section of the Huawei HCIA-Cloud Computing training material, the taxonomy of virtualization components is strictly defined. Statement C is FALSE because the virtualization software layer is technically called the Hypervisor or Virtual Machine Monitor (VMM), not the "Host OS." While a "Host OS" exists in Type-2 (hosted) virtualization (where the hypervisor runs as an application on top of an existing OS like Windows or Linux), the software layer that actually performs the resource abstraction and logical partitioning is the Hypervisor itself.

The other definitions are central to Huawei's technical documentation. AGuest OS(Statement A) is indeed the operating system—such as Windows Server or Ubuntu—that is installed inside a Virtual Machine. It is "unaware" that it is running on virtual hardware. TheHost Machine(Statement B) refers to the underlying physical server (e.g., a Huawei FusionServer Pro) that provides the actual CPU, RAM, and physical NICs. Finally, aGuest Machine(Statement D) is a synonym for a Virtual Machine (VM), representing the logical container that houses the Guest OS and applications.

In a Type-1 virtualization architecture (like HuaweiFusionCompute), the Hypervisor (CNA) sits directly on the hardware. In this scenario, there is no "Host OS" at all, further proving why statement C is incorrect. The Hypervisor is responsible for trapping "privileged instructions" from the Guest OS and translating them into actions on the physical hardware. Correctly identifying these roles—Host Machine, Hypervisor, and Guest VM—is a prerequisite for understanding more advanced cloud features like Resource Clusters and Distributed Resource Scheduling (DRS).

In FusionCompute architecture,CNAandVRMhave clearly defined deployment models.

OptionAis 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.

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

OptionCis true. When VRM is deployed on virtual machines, the active and standby VRM VMs must be placed ondifferent hosts within the management clusterto avoid single points of failure.

OptionDis true. VRM supports deployment oneither physical servers or virtual machines, providing flexible management options.

Therefore, the correct answers areB, C, and D.

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 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 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.

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.

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.

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.

In the FusionAccess architecture, the successful startup and availability of a virtual desktop depend on a process known as "VM Registration." According to the Huawei HCIA-Cloud Computing curriculum, the component responsible for receiving and processing these registration requests is the HDC (Huawei Desktop Controller).

The process works as follows: Each virtual desktop VM has a resident software agent called theHDA (Huawei Desktop Agent). When the VM boots up and the network is initialized, the HDA sends a registration request over the internal management network. This request contains the VM's status, its IP address, and its unique identifier. TheHDCacts as the central "command and control" center of the desktop cloud. It listens for these requests, verifies the VM's credentials against the system database (GaussDB), and updates the VM's status to "Ready" or "In Use."

The HDC is the core logical component that manages the relationship between users and their virtual desktops. If the HDC does not receive the registration request—perhaps due to a network issue or a failure of the HDA service on the VM—the desktop will appear as "Unregistered" or "Offline" in the management portal, and users will be unable to log in through the Web Interface (WI). While theITA (IT Adapter)is used by administrators totriggerthe provisioning of the VM, it does not handle the real-time registration traffic of individual VMs. Similarly, the HDA is thesenderof the request, not the receiver. Understanding the HDC's role as the registration authority is a fundamental requirement for troubleshooting connection issues and mastering the FusionAccess component interactions taught in the HCIA certification.

According to the HCIA–Cloud Computing virtualization domain,KVM (Kernel-based Virtual Machine)andXenare both examples ofhardware-assisted virtualizationtechnologies.

Hardware-assisted virtualization relies on CPU extensions such asIntel VT-xandAMD-Vto improve virtualization performance and isolation. Both KVM and Xen leverage these CPU features.

KVMis implemented as akernel modulewithin the Linux operating system. Once loaded, the Linux kernel itself becomes a hypervisor, managing CPU and memory virtualization with hardware support.

Xenalso relies on hardware virtualization features and interacts closely with the operating system kernel, especially in full virtualization and hardware-assisted modes.

Because the statement correctly describes both thevirtualization typeand theimplementation approach, it aligns with HCIA documentation and isTRUE.

Huawei FusionCompute implementsrole-based access control (RBAC)to ensure secure and compliant system management.

Thesecurity auditor roleis designed specifically for compliance and auditing purposes. According to HCIA–Cloud Computing materials, this role hasread-only permissions, allowing the user toview and export system logsbut not modify configurations or perform operational tasks.

This restriction helps ensure the integrity of audit records and prevents unauthorized system changes.

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.

According to the Huawei HCIA-Cloud Computing training material, system encapsulation is a vital process when creating a "Golden Image" for Full Copy virtual desktops. The primary tool used for this in Windows environments is Sysprep (System Preparation Tool). Statement A is TRUE because the fundamental purpose of Sysprep is to "generalize" the operating system. This process removes computer-specific information, such as the Security Identifier (SID), computer name, and specific hardware drivers. If multiple VMs were cloned from a template without this step, they would all share the same SID, leading to domain conflict issues and security vulnerabilities in an enterprise Active Directory environment.

Statement B is alsoTRUE. Sysprep includes a functionality to reset the Windows Product Activation clock (often referred to as a "rearm"). This allows the cloned virtual machines to start their grace period anew upon their first boot, which is essential for large-scale deployments before the KMS (Key Management Service) or other volume licensing activation takes place. Statement C is incorrect because encapsulation is the process of preparing an image, not the installation itself; while cloning from a template saves time, "encapsulation" does not perform the installation. Statement D is incorrect because administrators typically install all necessary service software and driversbeforeor during the Audit Mode phase of Sysprep to ensure the final template is fully equipped.

In the Huawei FusionAccess workflow, encapsulation is the penultimate step before converting the VM into a template. By stripping the uniqueness of the source VM, Sysprep ensures that every Full Copy desktop provisioned to an end-user starts as a clean, unique instance that can successfully join the corporate domain and receive independent security policies.

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

According to the HCIA–Cloud Computing curriculum underServer Basics, the CPU is defined as thecore component responsible for computation and controlwithin 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 thefetch–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 therole, composition, and working principleof the CPU as defined in Huawei’s HCIA–Cloud Computing documentation, it iscorrect.

The HCIA–Cloud Computing syllabus clearly defines the basic terminology used in virtualization.

OptionAis correct. Aguest OSrefers to the operating system installed and running inside a virtual machine.

OptionBis correct. Aguest machineis another term for a virtual machine (VM).

OptionCis correct. Ahost machinetypically refers to thephysical serverthat provides hardware resources for virtualization.

OptionDis false. Ahost OS is not the virtualization software layer. The virtualization layer is thehypervisor(such as KVM, Xen, or FusionCompute). In some architectures, the host OS and hypervisor may coexist, but they arenot the same concept.

Therefore, the false statement isD.

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.

FusionCompute uses aunified storage abstraction model. Regardless of whether the backend storage is SAN, NAS, local disks, or distributed storage, FusionComputeencapsulates storage resources into datastores.

This abstraction simplifies management and allows virtual machines to consume storage in a standardized manner. While statements A, B, and C describe correct individual concepts,D best represents the core architectural principleemphasized in HCIA documentation.

Therefore, the correct answer isD.

FusionCompute installation has clear host hardware and configuration requirements defined in the HCIA syllabus.

OptionAis true. The boot device must match the installation location of the host operating system to ensure system stability.

OptionCis true.CPU virtualization must be enabledin the BIOS (Intel VT-x or AMD-V). If not enabled, the host cannot run virtual machines, which is a mandatory prerequisite.

OptionDis true. FusionComputecan be installed with a single network interface, although this is not recommended for production environments. Multiple NICs are preferred for traffic separation and high availability.

OptionBis false. The host where theVRM is deployed has higher disk requirementsthan ordinary compute nodes because it runs management services, databases, and logs. Therefore, its disk requirements arenot the sameas other compute nodes.

Thus, the false statement isB.

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.

Bare VM creation rules in FusionAccess are strict to ensuretemplate consistency and successful provisioning:

Ais true: The system disk must useCommon configuration mode, not thin provisioning.

Bis true: For linked-clone bare VMs, NICs are addedafter template creation, during desktop provisioning.

Cis false: Bare VMs should usemanagement-plane networking, not user service-plane DVS/port groups.

Dis false: Thin provisioning isnot allowedfor the system disk of a bare VM.

Therefore, the correct answers areA and B.

When creating a Windows template in FusionAccess, the Template Tool must be mounted and installed inside the VM.

According to HCIA documentation:

The template tool installs necessary drivers, services, and agents required for desktop provisioning, management, and optimization.

Without mounting and installing the template tool, the VM cannot be converted into a usable desktop template.

Other operations such as configuration and conversion are subsequent steps, but mounting the template tool is mandatory.

Therefore, the correct answer is A.

In the shown topology, RTA and RTB are directly connected on10.0.0.0/24(RTA: 10.0.0.1/24, RTB: 10.0.0.2/24). RTB and RTC are directly connected on20.1.1.0/24(RTB: 20.1.1.2/24, RTC: 20.1.1.3/24). In HCIA networking fundamentals, a router forwards packets based on its routing table, and thenext hop must be reachable on a directly connected network(or resolved via recursion), meaning it is typically theneighbor router interface on the local link.

A is false: For traffic fromRTA to RTC (20.1.1.3), RTA’s next hop should beRTB’s interface 10.0.0.2(its directly connected neighbor). The address20.1.1.2is not on RTA’s directly connected subnet, so it cannot be used as the immediate next hop in this basic routing scenario.

B is true: RTC must have a route back to10.0.0.0/24(for return traffic to RTA). Since RTC only knows its directly connected network20.1.1.0/24, a static/default route is required pointing to20.1.1.2.

C is true: RTB has two directly connected networks (10.0.0.0/24 and 20.1.1.0/24), so it can reach both RTA and RTC withno additional routes.

D is false: RTB does not need extra routing configuration for RTA↔RTC communication because both networks are alreadydirectly connectedon RTB.

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.

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

In the Huawei FusionAccess solution, desktop provisioning is the process of creating and assigning virtual machines to users. The "provisioning proportion mode" is a key parameter in this process. Mode A (1:1) represents the "Single User" or "Static" assignment mode. In this configuration, one virtual machine is permanently bound to one user. This is typically used for Full Copy desktops where the user requires a persistent environment with their own dedicated storage and personalized settings. The user has exclusive rights to the VM, and their data remains on the disk even after logging off. This ensures the highest level of personalization and performance for individual employees.

Mode B (1:N) represents the "Dynamic" or "Pool" assignment mode. In a 1:N scenario, a group of users shares a pool of virtual machines. This is commonly implemented using Linked Clone technology to save storage space and simplify management. For example, in a task-oriented environment like a call center or a training center, multiple users (N) can log into a set of virtual machines based on the same template (1) at different times. The system assigns an available VM from the pool to the user upon login. This maximizes resource utilization because not all users are online simultaneously.

Furthermore, the selection of these modes directly affects the backend storage design and the maintenance strategy. For 1:1 desktops, backup and disaster recovery must be managed per individual VM, whereas for 1:N pooled desktops, the administrator focuses on the security and integrity of the "Golden Image" or parent template. Understanding these two primary modes is crucial for administrators to choose the right technology—Full Copy for persistent 1:1 needs or Linked Clone for efficient 1:N pools—based on user requirements and hardware capacity.

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

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 Linux-based virtualization environments, aTAP deviceis a software-based virtual network interface that operates atLayer 2of the OSI model.

TAP devices are independently maintained by the Linux kernel and are commonly used to connect virtual machines to virtual switches or bridges. They simulate physical Ethernet interfaces, allowing VMs to send and receive Ethernet frames.

This definition aligns with HCIA–Cloud Computing networking fundamentals, so the statement isTRUE.

In Huawei FusionAccess, user authentication and authorization for Windows desktops are typically integrated withActive Directory (AD). During VM template creation, the option“Configure user login”is used to specify who is allowed to log in to the virtual desktop.

According to the HCIA–Cloud Computing FusionAccess service provisioning process, this option is selected whenAD group membersare intended to access the VM. FusionAccess then uses AD-based authentication to control desktop login permissions, ensuring centralized identity management and consistent security policies.

Therefore, the correct word shown on the GUI and required to complete the sentence isAD.

In the official Huawei HCIA–Cloud Computing documentation, the core definition of virtualization centers on the abstraction of physical resources. The essence of virtualization technology is precisely the transformation of physical, hardware-based resources—such as CPUs, memory, network interface cards, and storage disks—into virtualized, logical entities. This process is facilitated by a software layer known as the Hypervisor or Virtual Machine Monitor (VMM). By creating this abstraction layer, virtualization effectively achieves the "decoupling" of the software environment (the Operating System and applications) from the underlying physical hardware.

This decoupling is a revolutionary shift from traditional computing architectures where an Operating System was tied to specific hardware drivers and physical configurations. In a virtualized environment, a Virtual Machine (VM) perceives a set of standardized, logical hardware components provided by the Hypervisor. Because the software is no longer bound to the physical machine, it gains significant mobility and flexibility. For example, in Huawei’s FusionCompute platform, this decoupling allows for features such as Live Migration, where a running VM can be moved from one physical host to another without any service interruption. This is possible because the VM's "logical" hardware remains consistent even as the "physical" host changes.

Furthermore, this transformation from physical to logical enables better resource utilization through overcommitment and sharing. Multiple logical servers can run on a single physical server, each isolated from the others. This fundamental shift is what provides the agility, scalability, and efficiency required for Cloud Computing. Without the decoupling provided by virtualization, the rapid provisioning and elastic resource scaling that define cloud services would be impossible to achieve. Therefore, virtualization serves as the indispensable technical foundation upon which all other cloud services and management layers are built within the Huawei ICT ecosystem.

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.

According to the Huawei HCIA-Cloud Computing training materials, the statement is TRUE. TAP (Network TAP) is a virtual network kernel device that is part of the standard Linux kernel networking stack.2 It is "independently maintained" because it is a native Linux feature, not a proprietary tool built solely for a specific hypervisor like KVM or Xen. TAP devices operate at the Data Link Layer (Layer 2) of the OSI model, meaning they handle Ethernet frames.3

In a cloud computing environment, TAP devices are fundamental for bridging the gap between virtual machines and the physical network. When a Virtual Machine is created, the hypervisor (CNA in Huawei's case) creates a TAP device on the host. One end of this TAP device is "plugged" into the virtual machine's NIC, while the other end is connected to a virtual switch (like the DVS or Linux Bridge). This allows the VM to send and receive Ethernet frames as if it were connected to a physical switch port.

Linux maintains TAP alongside its counterpartTUN(which operates at Layer 3/Network Layer).4Because TAP carries full Ethernet headers, it is the preferred device for virtual switches, as it allows for features like VLAN tagging and MAC address learning. Huawei’s virtualization technology leverages these standard Linux kernel features to provide a high-performance, stable networking environment. Understanding that TAP is a standard, independent Linux kernel component is vital for candidates, as it explains how open-source foundations are used to build enterprise-grade cloud platforms like FusionCompute.

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

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.

In HCIA–Cloud Computing (Operating System Basics), Linux network interface configuration is a foundational skill, and openEuler follows the standard Red Hat–style network configuration syntax.

To configure a static IP address, the parameter BOOTPROTO must be set to static. This tells the operating system not to request an IP address from a DHCP server and instead use the manually configured values such as IPADDR and NETMASK.

To ensure that the NIC is automatically activated when the system boots, the parameter ONBOOT must be set to yes. If ONBOOT is set to no, the interface will remain down after boot and must be manually started.

Therefore, the completed and correct configuration is:

BOOTPROTO=static

ONBOOT=yes

BOOTPROTO=static → Uses a fixed IP address

ONBOOT=yes → Enables automatic startup at system boot

This configuration exactly matches HCIA–Cloud Computing requirements for static IP configuration on openEuler.
