Huawei H13-511_V5.5 HCIA-Cloud Computing V5.5 Exam Exam Practice Test

Huawei FusionCompute provides a comprehensive virtualization platform with advanced management and scheduling capabilities.

Ais true. FusionCompute supportsdynamic resource adjustment, including CPU and memory scaling, helping applications adapt to workload changes.

Bis true. FusionCompute supportsx86 and Arm architectures, multiple storage backends, and mainstream operating systems such as Linux and Windows, ensuring broad application compatibility.

Cis true. SLA policies allow administrators to define priorities for virtual machines, ensuring that critical applications receive sufficient resources.

Dis true. FusionCompute supportsautomatic VM migration (such as DRS-like features)based on predefined policies to balance workloads and optimize system performance.

All listed statements correctly describe FusionCompute capabilities.

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.

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.

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.

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 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.

RAID technology is a key topic in theStorage Technology Basicsdomain of HCIA–Cloud Computing. Different RAID levels provide varying balances of performance, capacity, and fault tolerance.

RAID 0 (A)uses data striping across multiple disks to improve read/write performance but providesno data redundancy. This statement is correct.

RAID 1 (C)usesdisk mirroring, where identical data is written to two disks, ensuring high data reliability. This statement is correct.

RAID 5 (D)usesdistributed parityacross disks, allowing data recovery if one disk fails. This is also correct.

RAID 6 (B)is the false statement. RAID 6 doesnotuse mirroring. Instead, it usesdual parity, allowing the system to tolerate the failure oftwo disks simultaneously.

Therefore, optionBis incorrect and is the false statement.

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.

RAID 0

➡Multiple disks are combined to form a large-capacity storage device. This RAID level supports data striping to improve read and write speed, but does not provide data verification or redundancy backup.

RAID 1

➡Data on one disk is mirrored to another disk to provide complete redundancy backup.

RAID 5

➡Parity data is distributed on all disks in the array. Write operations can be performed on different disks at the same time.

RAID 10

➡Mirror backup is performed for each disk, and then the disks are combined to form a storage device, providing high read and write performance in addition to redundancy backup.

According to the Huawei HCIA-Cloud Computing curriculum, specifically the section on Huawei Desktop Protocol (HDP), the statement provided is FALSE. While the protocol does indeed perform "Intelligent Desktop Recognition" to classify bitmaps and apply different compression algorithms, the classification criteria are based on the image type (content characteristics), not the "sensitivity" of the data.

HDP classifies screen content into two primary categories:Non-natural images(such as text, lines, and desktop window frames) andNatural images(such as photographs, gradients, and video frames). For non-natural images like text, HDP uses alossless compression algorithm. This ensures that the edges of characters remain crisp and readable, preventing the "blurring" effect that can lead to eye strain. For natural images, the protocol uses alossy compression algorithm(such as H.264/H.265 based encoding). This significantly reduces the amount of data transmitted over the network while maintaining a visual quality that is acceptable to the human eye for pictorial content.

The term "non-sensitive data" used in the question is not a technical term within the HDP specification. A user's bank statement (highly sensitive) and a random text document (non-sensitive) would both be compressed using the lossless algorithm because they are both "text" content. Therefore, the compression logic is strictly content-aware to optimize the User Experience (UX) and bandwidth, regardless of the data's security classification. Understanding this distinction is vital for the exam as it highlights Huawei's "Graphics and Text Separation" technology.

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

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.

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.

According to the official Huawei FusionAccess installation and configuration guidelines, the process of creating a Windows VM template is highly structured to ensure compatibility with the Huawei Desktop Protocol (HDP). During the template making process—specifically when using the Huawei Desktop Preparation Tool—the system requires the use of a specific temporary account named PrivateAccount.

ThePrivateAccountis a built-in temporary administrative account used by the Huawei automation scripts to perform system-level tasks during the "encapsulation" phase. These tasks include installing the Access Agent, optimizing the operating system for a virtual environment (disabling unnecessary services like Windows Search or Aero effects), and configuring the registry to support remote login. This account is essential because it allows the system to operate independently of any domain-joined credentials or local administrator accounts that might be changed or locked during the preparation process.

In the HCIA-Cloud Computing curriculum, students are taught that the template creation workflow involves several steps: creating a bare VM, installing the Windows OS, installing drivers, and finally running the preparation tool. When the tool prompts for an account, the administrator must ensure thatPrivateAccountis used to maintain the integrity of the template. Once the template is successfully encapsulated and converted into a "Golden Image," this temporary account is typically deactivated or managed by the system to ensure security. Using a different account, such as a manually created "LocalAccount," may lead to errors during the automatic provisioning of desktops, as the FusionAccess management plane (ITA/HDC) specifically looks for the environment variables and permissions associated with the preset PrivateAccount during the initial boot of new clones.

Huawei FusionCompute leverageshardware-assisted virtualization technologiessuch asIntel VT-x, EPT, and AMD-V, which significantly reduce the overhead associated with CPU and memory virtualization.

Memory virtualization traditionally involved complex software-based address translation, which introduced performance overhead. With hardware-assisted features such asExtended Page Tables (EPT), memory mapping is handled directly by the CPU, improving efficiency and performance.

This approach is explicitly highlighted in HCIA–Cloud Computing materials as a key reason why FusionCompute delivers near-native performance for virtual machines.

Therefore, the statement isTRUE.

(Note: The original question contained a typo. As requested, "host OS" has been corrected to "guest OS" because Linux, in this scenario, is the Guest operating system.)

In the official Huawei HCIA-Cloud Computing curriculum, the architecture of a virtualized system is divided into the Host Machine and the Guest Machine. TheHost Machineis the physical server (hardware) and the virtualization software (CNA in FusionCompute). TheGuest Machineis the Virtual Machine (VM) created by the hypervisor. According to the training materials, theGuest OSis the operating system that is installed and executed within the virtualized environment of a VM.13

Therefore, if a VM running Linux is created, the Linux operating system is the Guest OS, and it runs specifically inside theLinux VM. The VM acts as a logical container that provides the Linux OS with virtualized CPU, memory, storage, and network resources.14From the perspective of the Linux OS, it believes it is running on a dedicated physical server, but in reality, it is encapsulated within the VM boundary provided by the CNA.

The other components mentioned have different roles:CNA (Computing Node Agent)is the "host" software that manages the hardware and hosts the VM, but the Linux OS does not run "in" the CNA directly; it runs in the VM managed by the CNA.VRM (Virtual Resource Management)is the management platform used by administrators to create and configure the VM.VNA (Virtual Node Agent)is a process within the CNA that handles management commands from the VRM. In the Huawei certification logic, it is crucial to distinguish between the "Container" (the VM) and the "Occupant" (the Guest OS). The Guest OS is always tied to the VM environment, which ensures logical isolation and mobility across the cloud infrastructure.

In the official Huawei HCIA-Cloud Computing curriculum, specifically the "Virtualization Basics" module, the characteristics of virtualized hardware are clearly defined. Statement D is FALSE because a Virtual Machine (VM) is not limited to a single virtual network interface card (vNIC). In fact, for many enterprise scenarios, a VM must have multiple vNICs. For example, a VM acting as a software firewall or a multi-homed server would require separate vNICs to connect to different logical networks (such as a Management network, a Service network, and a Backup network). Huawei FusionCompute supports the addition of multiple vNICs to a single VM, each capable of being assigned to a different port group or VLAN.

The other statements are correct based on Huawei’s technical standards. Statement A is true; every vNIC is assigned a globally uniqueMAC address(usually from a prefix reserved for Huawei virtualization) to ensure that Layer 2 switching functions correctly within the DVS. Statement B is true; just like a physical machine, each vNIC can be assigned a uniqueIP addressthrough static configuration or DHCP to allow for Layer 3 communication. Statement C is also accurate; from the perspective of the Guest Operating System, the vNIC behaves exactly like a physical PCI-E network card. It has a driver, it can be configured with MTU settings, and it can transmit and receive frames. The hypervisor (CNA) is responsible for intercepting the data from this "logical" NIC and forwarding it through the physical NICs of the host server. This transparent emulation is what allows standard operating systems and applications to run in the cloud without modification.

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

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.

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.

This statement is TRUE and covers two fundamental concepts within the Huawei HCIA-Cloud Computing curriculum: resource locality and High Availability (HA).

First, the statement addresses the constraint ofresource locality. In the current architecture of Huawei FusionCompute (and most mainstream virtualization platforms), a single Virtual Machine (VM) cannot "span" its core compute resources (vCPU and RAM) across multiple physical hosts simultaneously. For instance, if a physical host has 128GB of RAM, you cannot create a single VM with 256GB of RAM, because that VM’s memory address space must be mapped to the physical DIMMs of a single physical server to maintain performance and synchronization. Therefore, the maximum specifications of a VM are always bounded by the physical hardware limits of a single host within the cluster.

Second, the statement accurately describes theHigh Availability (HA)function. While a running VM is tied to one host, cloud computing overcomes this physical dependency through cluster-level management. When theVRM (Virtual Resource Management)node detects that a physical host has malfunctioned (via heartbeat loss), it triggers the HA policy. Since the VM’s disk files are stored on shared storage (like a SAN or NAS), the system "assigns" the VM to a different healthy host in the same cluster. The VM is then automatically restarted on that new host, which provides the necessary CPU and memory resources to resume services.

This combination of strict host-level resource allocation for execution and cluster-level flexibility for recovery is what allows Huawei’s cloud solutions to provide stable, enterprise-grade infrastructure. Understanding that compute resources are provided by a "single host" at runtime, but protected by the "cluster" during a failure, is a core objective of the HCIA-Cloud Computing certification.

Forsmall-scale office scenarios (≤100 users), the HCIA–Cloud Computing FusionAccess deployment guidelines recommend asimplified architecturethat balances availability and cost.

Deployingone integrated vAG + vLB VM on each CNA nodeprovides:

Basichigh availability

Reduced VM count

Simpler deployment and maintenance

Sufficient performance for small user规模

Separate deployment of vAG and vLB or multiple integrated VMs is more suitable formedium and large-scale environments.

Therefore, the recommended solution istwo CNA nodes, each deployed with a VM that integrates the vAG and vLB.

This statement isincorrectbased on HCIA–Cloud Computing virtualization concepts.

First,KVM is not a pure paravirtualization technology. It is ahardware-assisted full virtualizationsolution that relies on CPU virtualization extensions. While KVM can use paravirtualized drivers (such as Virtio) to improve performance, its core architecture is hardware-assisted virtualization.

Second, KVM supportsdevice I/O virtualization. Using technologies such asVirtio, KVM provides efficient virtual network and storage devices. This allows virtual machines to achieve near-native I/O performance, which is a key feature emphasized in HCIA training.

Because the statement incorrectly classifies KVM and wrongly claims that it cannot virtualize device I/O, the correct answer isFALSE.

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 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.

In the context of FusionAccess deployment, understanding Microsoft Active Directory (AD) is critical. According to the official Huawei curriculum, a Domain and an Organizational Unit (OU) serve different purposes in a network hierarchy. Statement A is TRUE because a domain is a security and administrative boundary; users authenticate "to the domain." An OU is merely a logical container inside that domain used for organization; it does not function as an authentication boundary itself.

Statement B isTRUE. Group Policy Objects (GPOs) are the primary tool for managing desktop settings in a Huawei VDI environment. GPOs can be linked at the Domain level (applying to everyone) or at the OU level (applying only to the users or computers within that specific folder). This allows FusionAccess administrators to apply specific security rules—such as disabling USB ports or setting custom wallpapers—to one department (one OU) without affecting the entire company.

Statement D is alsoTRUE. Both entities are containers for AD objects such as User accounts, Computer accounts, and Security Groups. However, statement C isFALSE. While an OU always existsinsidea domain (to organize that domain's objects), a domaincannotexist inside an OU. Domains exist within a Forest or Tree structure.2This distinction is vital for HCIA candidates because the FusionAccessITA (IT Adapter)requires a specific OU structure to be pre-created (e.g., an OU for Desktops and an OU for Users) to properly apply the automated provisioning and management policies that define the desktop cloud environment.

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

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 FusionAccess architecture:

HDC (Huawei Desktop Controller) is responsible for desktop lifecycle management, including provisioning logic, policy enforcement, and resource validation.

During VM creation, HDC verifies whether the specified VM group and desktop group exist and whether configurations are valid.

Other components:

GaussDB stores metadata.

HDA runs inside desktops.

HDP is a display protocol.

Thus, the correct answer is HDC.

Distributed storage is a core concept in cloud computing and is emphasized in HCIA–Cloud Computing as a foundational technology for large-scale cloud platforms.

OptionAis true. Distributed storage is designed forhorizontal scalability, allowing storage capacity and performance to increase simply by adding more nodes.

OptionBis true. Unlike traditional centralized storage systems, distributed storage typically runs ongeneral-purpose x86 servers, reducing cost and improving flexibility.

OptionCis false. Distributed storagedoes not rely on traditional RAIDfor data protection. Instead, it usesdata replication or erasure coding, which are more suitable for large-scale distributed environments.

OptionDis true. Distributed storage eliminates the need for dedicated controller enclosures or disk enclosures. Storage resources are directly provided bygeneral-purpose servers, which aligns with cloud-native architecture principles described in HCIA materials.

Access Interface

➡The sent packets do not carry VLAN tags.

An access interface belongs to only one VLAN.

Frames are sent untagged, making it suitable for end devices such as PCs and printers.

Trunk Interface

➡Only one VLAN tag can be removed from the sent packets.

A trunk interface allows multiple VLANs to pass.

Typically used for switch-to-switch connections.

Only the native VLAN is sent untagged; other VLANs are tagged.

Hybrid Interface

➡Multiple VLAN tags can be removed from the sent packets.

A hybrid interface supports both tagged and untagged VLAN traffic.

Multiple VLANs can be configured to send traffic without VLAN tags.

Commonly used for server connections and virtualization environments.

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 FusionAccess deployment,vAG (Virtual Access Gateway)andvLB (Virtual Load Balancer)rely oninternal account authentication and synchronizationto maintain high availability (HA) status.

Changing the following passwords can directly affect HA synchronization:

root password for vAG/vLB (D)

gandalf account password for vAG/vLB (C)

root password for HDC (A), which may disrupt management communication

However, theITA portal login password (B)is related only touser or administrator portal accessand doesnot participate in HA synchronization mechanisms.

Therefore, changing the ITA portal login password isnota cause of abnormal HA status.

In the Huawei HCIA-Cloud Computing curriculum, understanding the classification and reservation of IPv4 addresses is essential for proper network configuration within a virtualized data center. According to official documentation, certain address ranges are reserved for specific protocols or system functions and are strictly prohibited from being assigned to service hosts (end-user devices or servers).

Firstly,0.0.0.0is an unspecified address. It is used by a host that does not yet have an IP address when it sends a DHCP Discover packet to find a server. It also represents the "default route" in routing tables. Secondly, the127.0.0.0/8range is reserved for loopback testing. Any packet sent to this range never leaves the local host's internal network stack; it is used to verify that the TCP/IP suite is installed correctly. Thirdly,255.255.255.255is the "limited broadcast address." It is used to send data to every device on the current local network segment but is never routed across different subnets. Finally, the169.254.0.0/16range (represented here as a /24 subnet) is the Automatic Private IP Addressing (APIPA) range. If a host is configured to obtain an IP automatically but fails to contact a DHCP server, the operating system assigns an address from this range so the host can still communicate with others on the same link.

None of these addresses can be used as a source or destination for standard service traffic across a routed cloud infrastructure. Service hosts must be assigned either public IP addresses or private IP addresses from the RFC 1918 ranges (10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16). Assigning reserved addresses to service hosts would lead to routing conflicts, local loopback errors, or a complete failure of network communication within the Huawei FusionCompute or FusionAccess environment.

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

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 FusionAccess,templates must not be joined to a domain.

HCIA–Cloud Computing materials specify that:

Templates are created in aworkgroup environment.

Domain joining is performed during desktop provisioning, not at the template stage.

Joining a template to a domain can cause conflicts such as duplicate computer accounts.

Therefore, the statement isFALSE.
