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

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.

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

From the HCIA–Cloud Computing learning scope, the core advantages of using cloud services (including Huawei Cloud) are typically tied toagility, elasticity, and cost efficiency.

Quick service deployment and rollout (A)is a standard cloud advantage because cloud providers offer ready-to-use services, templates, and automated provisioning. This allows businesses—especially startups—to launch environments in minutes instead of purchasing, shipping, installing, and configuring physical infrastructure.

Flexible resource scaling (B)is one of the most emphasized cloud characteristics. Cloud resources can be scaledup/downbased on demand (elasticity), helping companies handle traffic spikes or reduce capacity during off-peak times without long procurement cycles.

Reduced hardware costs (D)is also a common advantage because the company avoids large upfront capital expenses (CapEx) for servers, storage, and networking. Instead, cloud typically follows apay-as-you-gomodel (OpEx), which is ideal for early-stage businesses with uncertain growth.

However,Higher hardware performance with the same configuration (C)isnotan inherent cloud advantage. If the virtual machine configuration (CPU, memory, disk type) is the same, cloud does not automatically guarantee higher performance than equivalent hardware elsewhere. Performance depends on factors such as underlying physical host load, storage type, network conditions, and service class—so “higher performance with the same configuration” is not a guaranteed benefit and therefore is the incorrect “advantage.”

Important note (transparency):I can format and answer based onHCIA domain concepts, but Icannot provide “exact extracts” from Huawei official copyrighted documentsin a verbatim way.

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.

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

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

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

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

The HCIA–Cloud Computing syllabus clearly defines responsibility boundaries forIaaS. In the IaaS model, the cloud provider deliversbasic infrastructure resources, including compute, storage, networking, and virtualization. The user is responsible for managingoperating systems, middleware, runtime environments, applications, and data.

OptionAis false becausevirtualization is managed by the cloud provider, not the user. In IaaS, users consume virtualized resources (such as ECS instances) but donotdeploy or maintain the underlying hypervisors or virtualization platforms.

OptionBis false. Only focusing on applications aligns with theSaaSmodel, where the provider manages everything else. In IaaS, users must also manage operating systems and system-level configurations.

OptionCis also false. Focusing only on applications and data corresponds more closely toPaaS, where the platform handles operating systems and runtime environments.

OptionDis thecorrect description of IaaS responsibilities, because users must manageoperating systems (systems) and applications, while the provider manages the infrastructure layer. Therefore, D is not false and is excluded from the answer.

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

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

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

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

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.

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 Huawei HCIA-Cloud Computing curriculum, specifically under the "Network Technology Basics" module, Open vSwitch (OVS) is introduced as a key component of software-defined networking (SDN). The primary technology used by OVS for remote access to its control plane and for the programmatic control of traffic flows is OpenFlow.5 OpenFlow is a standard communications protocol that allows an SDN controller (the "brain" of the network) to interact with the forwarding plane (the switch) of a network device.

OpenFlow enables "traffic control" by allowing the controller to define specificflow rules.6These rules tell the switch exactly how to handle packets based on various criteria such as source MAC, destination IP, or TCP port. Instead of the switch making local, autonomous decisions (as a traditional switch does), OVS uses OpenFlow to receive instructions from a centralized management layer. This is how Huawei’s cloud infrastructure achieves "remote access" for network orchestration; an administrator can change the network behavior of thousands of virtual machines across multiple physical hosts by pushing new OpenFlow tables from a central controller.

WhileOVSDB(Option B) is also a critical protocol for OVS, its primary role is to manage theconfigurationof the switch (such as creating bridges, adding ports, or setting up tunnels), rather than the "traffic control" or "flow steering" handled by OpenFlow.BFD(Option C) is used for link failure detection, andNQA(Option D) is a Huawei-specific tool for measuring network performance. In the context of the HCIA exam, OpenFlow is the correct answer for the protocol that enables the intelligent, remote management of data paths in a virtualized network environment.

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

According to the HCIA–Cloud Computing curriculum, the evolution of cloud computing architecture reflects changes intechnology openness, business importance, resource scale, and data characteristics.

OptionAis correct because early cloud platforms were often proprietary and closed, while modern cloud computing architectures increasingly adoptopen-source technologies(such as OpenStack and Kubernetes) and open architectures to improve interoperability and innovation.

OptionBis also correct. Cloud computing initially hostednon-critical workloadssuch as testing, development, and backup systems. As reliability, security, and availability improved, cloud platforms became capable of supportingmission-critical enterprise applications, including ERP, financial systems, and core business services.

OptionDcorrectly describes the evolution of cloud architecture. Early virtualization focused onsmall-scale resource integration, while modern cloud computing emphasizeslarge-scale resource pools, enabling centralized management, elastic scheduling, and efficient utilization of massive compute, storage, and network resources.

OptionCisfalse. The evolution of cloud computing data has movedfrom structured data to semi-structured and unstructured data, not the other way around. With the rise of big data, IoT, social media, logs, images, and videos, cloud platforms are increasingly designed to processmassive volumes of unstructured and semi-structured data, which is a key trend emphasized in HCIA learning materials.

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.

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

In the Huawei FusionCompute architecture, network traffic is logically divided into specialized "planes" to ensure security, isolation, and optimal performance. TheBMC plane(Baseboard Management Controller) is dedicated to hardware-level management. It utilizes a dedicated network port on the physical host toenable remote access to the BMC system, allowing administrators to perform out-of-band tasks such as power control, BIOS configuration, and hardware health monitoring regardless of the OS state.

TheManagement planeis the communication backbone for the virtualization platform. It is used by the Virtual Resource Management (VRM) and Computing Node Agent (CNA) tomanage all nodes in a unified manner. All nodes in the cluster communicate on this plane to report resource status and receive management instructions. TheStorage planeis specifically reserved for data transmission between the compute hosts and the back-end storage infrastructure. This is theplane on which hosts communicate with storage units(such as LUNs or shared folders) to handle VM disk I/O.

TheService planeis the network segmentused by user VMsfor their actual service traffic. It carries the data produced and consumed by the applications running inside the virtual machines. Huawei documentation mandates the isolation of these planes—typically via VLANs—to prevent a "broadcast storm" or high data load in one plane (like Storage) from impacting the accessibility of the Management plane or the performance of user services.

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.

During quick provisioning in FusionAccess:

Administrators mustselect a VM template.

AVM groupmust be specified for management purposes.

Thenumber of VMsto be provisioned must be entered.

However,desktop group selectionis not required at the VM creation stage. Desktop groups are associatedlater during desktop assignment, not during VM creation.

Therefore, the correct answer isC.

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.

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

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.

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 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.

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

FusionCompute supportsmemory overcommitmentto improve overall memory utilization in virtualized environments. The supported technologies include:

Memory sharing

Memory ballooning

Memory swapping

According to HCIA–Cloud Computing materials, after enabling memory overcommitment incluster resource control, administrators mustselect at least one memory overcommitment mechanismto take effect.

Therefore, the statement correctly describes FusionCompute behavior and isTRUE.

In Active Directory (AD),domainsandorganizational units (OUs)serve different purposes.

Ais true. Both domains and OUs can contain AD objects such as users, computers, and groups.

Bis true. Authentication is performed at thedomain level. Users log in to a domain, not to an OU.

Cis true.Group Policy Objects (GPOs)can be applied at both the domain level and the OU level.

Dis false. An OU can existinside a domain, but adomain cannot exist inside an OU. Domains are top-level logical boundaries.

Therefore, the correct answers areA, B, and 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.

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.

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.

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.

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.

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 FusionCompute, VM live migration between hosts withdifferent CPU modelsrequires CPU instruction compatibility. Huawei provides theIMC (Instruction Masking Compatibility) policyat the cluster level to address this issue.

TheCluster IMC policymasks advanced CPU instruction sets so that VMs only see a common subset of CPU features supported by all hosts in the cluster. This ensures that a VM can migrate safely between CNA hosts with different CPU generations or models without encountering instruction incompatibility errors.

Other options are unrelated:

I/O ring adaptationfocuses on I/O optimization.

HANA optimizationis specific to SAP HANA workloads.

Guest NUMA policyoptimizes memory access, not CPU compatibility.

Therefore, the correct answer isCluster IMC policy.

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.

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.

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 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.
