H13-511_V5.5 Questions and Answers

The HCIA–Cloud Computing syllabus defines clear terminology for virtualization components.

The Guest OS is the operating system installed and running inside a virtual machine. It operates as if it were running on physical hardware, but all hardware access is abstracted by the hypervisor.

The hypervisor (A) is the virtualization layer that manages physical resources and virtual machines.

The host OS (B) is the operating system running on the physical server (in hosted virtualization models).

The host machine (D) refers to the physical server itself.

Therefore, the correct answer is Guest OS.

According to the Huawei HCIA-Cloud Computing documentation, security groups act as a distributed virtual firewall for Virtual Machines (VMs). Statement C is FALSE because FusionCompute allows a single Virtual Machine (or more specifically, a virtual NIC) to belong to multiple security groups simultaneously. This multi-group association allows for tiered security policies, such as having one security group for general web traffic and another for specific management access. When a VM belongs to multiple groups, the rules from all groups are aggregated to determine the final access control list.

Statement D is alsoFALSEbecause of the terminology regarding the "creation" location. In the FusionCompute architecture, security groups are logical objects created and managed within theVRM (Virtual Resource Management)portal, not "on the VMs" themselves. A security group exists independently of any specific VM; administrators create the group and define its rules first, and then they associate VMs with that group. Furthermore, users do not add rules "on VMs"; they add rules to the security group object in the management plane, which the system then automatically pushes to the corresponding CNA hosts where the VMs are running.

The other statements are technically accurate. Statement A is correct as Huawei’s security groups utilize the underlying LinuxiptablesorOVS (Open vSwitch)flow rules to filter packets at the hypervisor level. Statement B is also true; a VM's security group membership can be modified dynamically while the VM is in a running state without requiring a restart or causing a service interruption. This flexibility is a key feature of Huawei’s software-defined networking, allowing for real-time security adjustments in a dynamic cloud environment.

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

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

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

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

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

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

Thus, the false statement isB.

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.

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.

In the official Huawei HCIA-Cloud Computing documentation, specifically the "FusionAccess Security" module, the system is described as having a multi-layered security architecture. These four access management policies are the primary tools used to control entry into the virtual desktop environment.

MAC address-based control (A)allows administrators to bind specific users or groups to authorized hardware devices. This ensures that even if a password is compromised, the user can only log in from a company-issued terminal.Time-based control (B)functions as a whitelist; it defines a "valid window" (e.g., 08:00 to 18:00) during which desktop access is permitted. Outside of these hours, the system rejects connection attempts, which is critical for managing contractors or ensuring compliance with labor regulations.

IP address-based control (C)is highly flexible, supporting both blacklists (to block known malicious ranges) and whitelists (to allow only local office subnets). Administrators can define these rules for individual IPs or entire CIDR blocks. Finally,Certificate-based control (D)provides the highest level of identity assurance. Unlike the other policies which can be granular, certificate authentication is typically a global system setting in the ITA/HDC configuration. When enabled, every client must present a valid digital certificate issued by a trusted Certificate Authority (CA) before they are even prompted for a username and password.

By combining these policies, Huawei FusionAccess creates a "Zero Trust" style environment where access is granted based on the user's identity, their physical device, their location (IP), and the time of day. Understanding how to configure these policies in theITA (IT Adapter)portal is a key requirement for the HCIA-Cloud Computing certification and essential for maintaining a secure enterprise desktop cloud.

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

In FusionCompute architecture,CNAandVRMhave clearly defined deployment models.

OptionAis false.CNA is deployed only on physical servers(compute nodes). It is responsible for interacting directly with hardware resources and cannot run inside a VM.

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

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

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

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

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.

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.

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.

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.

Cloud-native architecture emphasizesapplication-level design and management, focusing on agility, scalability, and resilience.

Microservices,containers, andservice meshesare core cloud-native technologies.

Virtualizationis a foundational cloud technology but belongs totraditional cloud infrastructure, not cloud-native application architecture.

Therefore, the correct answer isVirtualization.

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.

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

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.

In AD,OUsanduser groupsare both used for organizing and managing resources, but they differ in function.

Ais true. Both OUs and user groups areAD objects.

Bis true. An OU can contain multiple types of AD objects, includingusers, computers, printers, and shared resources.

Cis false.Group policies cannot be directly applied to user groups; they are applied to domains, sites, or OUs.

Dis false. A user group can containusers, computers, and even other groups, not only user accounts.

Thus, the correct answers areA and B.

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

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

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

Emerging Technology

Feature / Application Scenario

Edge computing

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

Blockchain

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

Cloud native

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

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

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

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

According to the Huawei HCIA-Cloud Computing 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.

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

Huawei Desktop Protocol (HDP) is a proprietary protocol optimized for cloud desktop scenarios and is a key topic in the FusionAccess learning scope.

HDP usesintelligent bitmap classification:

Text and fine detailsuselossless compressionto ensure clarity and readability.

Images, videos, and nonsensitive graphicsuselossy compression, which significantly reduces bandwidth consumption while maintaining acceptable visual quality.

This adaptive compression strategy allows FusionAccess to deliversmooth user experienceeven in limited bandwidth environments, which is a highlighted advantage in HCIA materials.

Therefore, the statement isTRUE.

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.

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

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

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

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

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.

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.

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

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

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

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

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

Thus, the false statement is C.

According to the Huawei HCIA-Cloud Computing technical guidelines, storage is categorized by its connection method and the protocol used to access data. Direct Attached Storage (DAS) is the most basic form, where storage devices are connected directly to a single server via an internal bus or external cable. While simple, it lacks the scalability and resource-sharing capabilities required for modern cloud data centers. Network Attached Storage (NAS) provides file-level access over a standard IP network, typically using protocols like NFS or CIFS, allowing multiple clients to share a central pool of files over a local area network.

The Storage Area Network (SAN) is a specialized, high-speed network that provides block-level access to storage, making it appear to the operating system as a locally attached disk. In Huawei’s virtualization solutions, SANs are the preferred choice for high-performance clusters and features like VM Live Migration. As the statement correctly identifies, SANs are primarily divided into two types based on the transport protocol used: Fibre Channel (FC) SANs and IP SANs. FC SANs utilize dedicated fiber-optic cables, FC switches, and Host Bus Adapters (HBAs) to transmit data using the Fibre Channel protocol, offering extremely high reliability and minimal latency. Conversely, IP SANs utilize standard Ethernet infrastructure and the iSCSI protocol to encapsulate SCSI commands into IP packets. This allows for lower costs and easier management by leveraging existing Ethernet knowledge. Understanding these distinctions is crucial for the HCIA exam, as the choice between FC and IP SAN directly impacts the deployment architecture and performance characteristics of Huawei's FusionCompute and FusionAccess solutions in an enterprise environment.

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

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

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

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

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