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

According to the Huawei HCIA-Cloud Computing training materials, the statement is FALSE. In a Distributed Virtual Switch (DVS), a port group is a management object used to define common attributes for a collection of virtual ports. These attributes include VLAN settings, security policies, and Quality of Service (QoS) parameters. When an administrator configures a priority (such as an 802.1p priority tag) within a port group, that configuration applies to the entire port group, meaning all VMs connected to that group share the same policy.

The system does not allow for the setting of individual "priorities" for each specific member port (VM port) directly within the port group configuration. Instead, the port group ensures consistency across the virtual network. If different VMs required different priorities, they would typically be placed into different port groups, each with its own specific QoS and VLAN configuration.

It is important to distinguish this fromUplink Groups. In an uplink group (which connects the DVS to physical network cards), administratorscanset priorities or active/standby states for physical member ports (NICs) to control traffic flow and redundancy. However, for the virtual ports used by VMs within a standard port group, the logic is based on uniform policy enforcement. Huawei's documentation emphasizes that port groups are designed to simplify management by allowing the administrator to configure a policy once and have it apply to all associated VM NICs, thereby reducing the risk of manual configuration errors on a per-port basis.

As detailed in the Huawei HCIA-Cloud Computing training material regarding FusionAccess Service Provisioning, the statement is TRUE. Huawei FusionAccess is designed to support complex enterprise environments, including multi-domain architectures. This is particularly relevant for large corporations that have acquired other companies or have organized their IT infrastructure into a forest of multiple Active Directory (AD) domains.

FusionAccess achieves this by establishingTrust Relationshipsbetween the "Management Domain" (where the infrastructure components like HDC and ITA are located) and the "User Domains" (where the desktop users' accounts are stored). When trust is correctly configured between AD domains, theHDC (Huawei Desktop Controller)can query and authenticate users across these boundaries. For instance, a user from marketing.huawei.com and another from research.huawei.com can both log into the same Web Interface (WI) and access their respective virtual desktops.

During the service provisioning process, the administrator adds the various domains to the FusionAccess management system. When a user logs in, they specify their domain prefix (e.g., DOMAIN_A\username), and the system routes the authentication request to the appropriate Domain Controller. This multi-domain support is critical forMulti-tenancyand large-scale enterprise consolidation. It allows a single, unified FusionAccess platform to serve multiple organizational units without requiring all users to be migrated into a single, massive AD domain. This logical separation is a key feature taught in the HCIA curriculum to demonstrate the scalability and flexibility of Huawei's virtual desktop solution.

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.

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 covered in the "Cloud Computing Trends" and "Huawei Cloud Solutions" modules of the HCIA curriculum, OpenStack and FusionCompute occupy different layers of the cloud stack. Statement A is correct: OpenStack is a global open-source project maintained by a community, whereas FusionCompute is Huawei’s proprietary commercial virtualization platform (hypervisor).4

Statement B captures a fundamental technical difference. OpenStack is anorchestratoror "Cloud OS"; it lacks an internal hypervisor and must rely on external technologies (like KVM, Xen, or FusionCompute itself) to perform the actual virtualization. In contrast, FusionCompute is a standalonevirtualization suitethat includes the CNA (hypervisor) and VRM (management), allowing it to directly pool and manage physical hardware resources.

Statement C highlights the broader scope of OpenStack, which is designed to manage heterogeneous resources, including Bare Metal (Ironic) and Containers (Zun/Magnum). FusionCompute is a specialized tool primarily focused on Virtual Machines (VMs). Finally, Statement D refers to theMulti-tenancymodel. OpenStack was built for public and large private clouds, using "Projects" and "Tenants" to strictly isolate resources and billing between different organizations. FusionCompute is a lower-level resource manager that focuses on "Clusters" and "Resource Pools" rather than the complex tenant-based isolation logic found in high-level cloud platforms. In the Huawei ecosystem, FusionCompute often serves as the "Computing" component underneath a largerHuawei Cloud Stackor OpenStack-based solution, illustrating how these two technologies complement each other in a modern data center.

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

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

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

According to the 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.

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

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

Therefore, the correct answer isD.

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.

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.
