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

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 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.

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.

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 official Huawei FusionAccess documentation, " Quick Provisioning " is a streamlined workflow designed to deploy multiple virtual desktops efficiently.1 For this process to succeed, several mandatory parameters must be defined to ensure the Virtual Machines (VMs) are created with the correct hardware and software specifications.

First, theComputer Type (A)is mandatory as it determines whether the desktops will be " Full Copy " (independent disks) or " Linked Clone " (shared base disk). This choice significantly impacts storage consumption and future maintenance. Second, aTemplate (D)is required because it serves as the " Golden Image " containing the pre-installed Operating System, drivers, and the Huawei Access Agent (HDA). Without a template, the system cannot instantiate the VM ' s disk content. Third, a targetHost (B)or resource cluster must be selected to provide the physical CPU and memory resources required for the VMs to run.

WhileSecurity Groups (C)are an important part of the network configuration, they are typically associated with a " Desktop Group " rather than being a mandatory field in the quick provisioning wizard itself. If no specific security group is selected, the system often applies a default policy. According to the HCIA curriculum, the core " Provisioning Plan " focuses on the source (Template), the deployment mode (Computer Type), and the destination (Host/Cluster). Ensuring these three parameters are correctly matched is vital for the automated provisioning engine to calculate resource availability and successfully trigger the VM creation on the backend FusionCompute platform.

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

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.

According to the Huawei HCIA-Cloud Computing technical guidelines for FusionAccess Service Provisioning, assignment types dictate the persistence and reusability of virtual desktops. The scenario described—where a VM cannot be re-assigned after being unassigned—points specifically to the " Assign a Computer to a User " (Single User/Static) assignment type.

In a " Single User " (1:1) assignment model, a permanent bond is created between a specific user and a specific Virtual Machine. This is the hallmark of Full Copy desktops used for persistent work environments. When an administrator " unassigns " a user from such a desktop, the VM is essentially " locked " to the user ' s previous data and profile settings to prevent data leakage or configuration contamination. In many Huawei VDI security policies, a VM that was once statically assigned to an individual contains personalized information that is not automatically wiped. Therefore, it cannot be simply " re-assigned " to another user without a manual cleanup or deletion and re-provisioning process.

In contrast, " Pooled " or " Multiple User " (1:N) assignments are designed for reusability. In those modes, once a user logs off or is unassigned, the VM returns to a common pool and is immediately available for the next user. The " Assign a Computer to a User " mode is prioritized for high-security or high-personalization roles where the desktop is treated like a physical PC. Huawei ' s documentation clarifies that for Full Copy VMs in a 1:1 relationship, the unassignment process typically signifies the end of that VM ' s specific lifecycle for that user. Understanding this behavior is crucial for administrators to avoid " resource stranding, " where VMs remain in the system but cannot be assigned to new staff due to the persistence constraints of the 1:1 assignment model.

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

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 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.

According to the Huawei HCIA-Cloud Computing technical manual, the statement is TRUE. A Virtual Local Area Network (VLAN) is a technology used at the Data Link Layer (Layer 2) to partition a physical switch or a network into multiple logical segments. In a traditional local area network, all devices connected to the same set of switches belong to a single broadcast domain. This means that any broadcast packet (such as an ARP request) is sent to every single port, which can lead to " broadcast storms " and security vulnerabilities as the network scales.

VLAN technology solves this by logically dividing the physical infrastructure. Each VLAN acts as its own independent broadcast domain. Even if two hosts are physically plugged into the same switch, if they belong to different VLANs (e.g., VLAN 10 and VLAN 20), they cannot communicate directly at Layer 2. A broadcast sent by a host in VLAN 10 will only be received by other hosts in VLAN 10. This isolation provides two major benefits in a cloud environment:SecurityandEfficiency. Security is enhanced because traffic from one department or tenant is logically separated from others, preventing unauthorized sniffing. Efficiency is improved by reducing unnecessary broadcast traffic, which preserves bandwidth and CPU cycles on the connected hosts.

In Huawei’s virtualization platform,FusionCompute, VLANs are a critical component of " Distributed Virtual Switches " (DVS). When administrators create port groups for Virtual Machines, they often assign a VLAN ID to that group. This ensures that the virtual machines are logically placed in the correct network segment. For hosts in different VLANs to communicate, a Layer 3 device (like a router or a Layer 3 switch) must perform " inter-VLAN routing. " This strict separation at the logical level is what allows cloud providers to host multiple tenants on shared physical hardware securely.

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

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.

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

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.

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

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

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

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

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

Thus, the false statement is C.

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 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.

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.

Scenario

Operation

User data is stored in a network directory instead of a local host.

Folder redirection

The client IP address segment is not configured. Users can access VMs from any IP address segment.

Access control policy

A parallel-to-USB cable can be used to connect the parallel port device to the client.

Peripheral policy creation

In FusionAccess, policy management allows for deep customization of the user environment.Folder redirectionis a key feature for maintaining data persistence and centralized backup. It ensures thatuser data is stored in a network directoryrather than locally on the virtual machine ' s disk. This prevents data loss if a VM is refreshed or deleted, which is common in linked-clone pool environments.

Access control policiesare used to define the security boundaries of the VDI environment. When theclient IP address segment is not configured, it defaults to a permissive state whereusers can access VMs from any IP segment. Administrators typically use this policy to restrict access to known corporate subnets or specific VPN ranges to enhance overall security.Peripheral policy creationprovides support for legacy hardware or specialized equipment. By configuring these policies, aparallel-to-USB cable can be usedto bridge legacy parallel port devices to the modern USB ports of the client terminal, ensuring business continuity for specialized printing or diagnostic hardware.

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

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

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

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

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.

FusionAccess OA security architecture adoptszone-based isolation(red, yellow, green zones).

Each zone islogically and physically isolated

Each zone has itsown FusionAccess system

Data is not allowed to flow freely between zones

OptionBis false because it incorrectly states that data can be transmitted between zones. The other statements correctly reflect FusionAccess OA security and integration characteristics.

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.

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.

All four statements accurately describe keyinitialization and configuration principlesof FusionAccess:

Ais true: When Windows AD is interconnected and local authentication is disabled,AD authentication has higher prioritythan LiteAS.

Bis true: vAG/vLB deployment requires properWI cluster configurationto enable access services.

Cis true: To avoid backup data loss caused by infrastructure failures,external FTP backup serversare recommended in production networks.

Dis true: When a License supports multiple charging modes, administrators must explicitly chooseUser Count or Concurrent User Count.

Thus,all options are correct.

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.

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

VLAN technology is a fundamental topic in HCIA–Cloud Computing, especially for cloud network isolation and segmentation.

OptionAis false. Atrunk linkis designed to carry traffic frommultiple VLANs using VLAN tags (802.1Q). Untagged traffic typically belongs to anative VLAN, not multiple VLANs.

OptionBis false. Ahybrid interfacecanbe used to connect a switch to a server. Hybrid interfaces support both tagged and untagged VLAN traffic and are commonly used in server and virtualization scenarios.

OptionCis true.Trunk interfacesare primarily used to connectswitch-to-switchlinks, allowing multiple VLANs to pass between switches.

OptionDis false.Access interfacesare designed to connectend devices(such as PCs or printers) and carry traffic foronly one VLAN, not for switch interconnections.

Therefore, the false statements areA, B, and D.

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.

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.
