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

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.

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.

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.

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.

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.

In the official Huawei ICT Academy curriculum, virtualization is defined as the core enabling technology that transforms physical hardware into logical, manageable resources. This process involves the introduction of a virtualization layer, often referred to as a Hypervisor or Virtual Machine Monitor (VMM), which sits between the physical hardware and the operating systems. The statement is TRUE because it accurately captures the three primary characteristics of virtualization as defined in Huawei’s technical documentation: Simulation, Isolation, and Sharing.

Simulationrefers to the ability of the Hypervisor to present a consistent set of virtual hardware (CPU, Memory, I/O) to the Guest Operating System, regardless of the underlying physical vendor. This allows software to run in an environment it perceives as dedicated physical hardware.Isolationis a critical security and stability feature; it ensures that if one Virtual Machine (VM) crashes or is compromised, it does not affect the operation of other VMs on the same physical host. Each VM operates in its own logical container with dedicated boundaries. Finally,Sharingallows multiple VMs to occupy a single physical server simultaneously, maximizing resource utilization.

Before virtualization, the "one-server-one-application" model led to massive resource wastage (often using only 5%–15% of capacity). By creating alogical representationof physical resources, virtualization enablesCloud Computingto achieve its goal of multi-tenancy and elastic scaling. In Huawei’sFusionComputearchitecture, this is implemented through theCNA (Computing Node Agent), which uses the Galax88 engine to virtualize CPU and memory resources and theVNA (Virtual Node Agent)for management, effectively decoupling the software from the hardware constraints.

In standard FusionAccess architecture, a site generally requiresone pair of vLBs(active/standby) to provide load balancing and high availability for user access traffic.

Additional vLB pairs are only required inlarge-scale or multi-site deployments. For most enterprise scenarios described in HCIA materials,one pairis sufficient.

Therefore, the correct answer is1 pair.

Huawei FusionComputeHigh Availability (HA)is designed to improve service continuity by automatically responding to VM or host failures.

OptionAis true. FusionCompute allows administrators to configuredifferent HA policiesfor virtual machines based on service importance, which aligns with SLA-driven management principles.

OptionCis true. One of the core functions of HA isautomatic VM rebootwhen a virtual machine encounters a failure, ensuring rapid service recovery.

OptionDis true. FusionCompute continuously monitorsCNA host and VM status. If a CNA host fails, HA triggers VM migration or restart on another available host in the same cluster, minimizing downtime.

OptionBis false. Even when usingshared storage, HAdoes not guarantee zero data loss. HA focuses onservice recovery, not data consistency. Data loss may still occur depending on application state and write operations at the time of failure.

Therefore, the false statement isB.

In the Huawei FusionAccess solution, desktop provisioning is the process of creating and assigning virtual machines to users. The "provisioning proportion mode" is a key parameter in this process. Mode A (1:1) represents the "Single User" or "Static" assignment mode. In this configuration, one virtual machine is permanently bound to one user. This is typically used for Full Copy desktops where the user requires a persistent environment with their own dedicated storage and personalized settings. The user has exclusive rights to the VM, and their data remains on the disk even after logging off. This ensures the highest level of personalization and performance for individual employees.

Mode B (1:N) represents the "Dynamic" or "Pool" assignment mode. In a 1:N scenario, a group of users shares a pool of virtual machines. This is commonly implemented using Linked Clone technology to save storage space and simplify management. For example, in a task-oriented environment like a call center or a training center, multiple users (N) can log into a set of virtual machines based on the same template (1) at different times. The system assigns an available VM from the pool to the user upon login. This maximizes resource utilization because not all users are online simultaneously.

Furthermore, the selection of these modes directly affects the backend storage design and the maintenance strategy. For 1:1 desktops, backup and disaster recovery must be managed per individual VM, whereas for 1:N pooled desktops, the administrator focuses on the security and integrity of the "Golden Image" or parent template. Understanding these two primary modes is crucial for administrators to choose the right technology—Full Copy for persistent 1:1 needs or Linked Clone for efficient 1:N pools—based on user requirements and hardware capacity.
