Huawei HCIA-Cloud Computing V5.5 Exam H13-511_V5.5 Exam Dumps: Updated Questions & Answers (January 2026)

In the Huawei HCIA-Cloud Computing curriculum, specifically within the "Storage Technology Basics" module, the comparison between centralized and distributed storage is a fundamental topic. Statement A is FALSE because it incorrectly suggests that reading data from multiple independent devices simultaneously has a negative impact on read efficiency. According to the official technical documentation, the opposite is true: distributed storage utilizes a parallel I/O architecture. When a data request is made in a distributed system (such as Huawei FusionStorage), the system retrieves data blocks from multiple nodes at once. This concurrency significantly improves the overall throughput and read/write speed of the system rather than "affecting" it negatively.

The other statements are technically accurate according to Huawei standards. Centralized storage (Statement B) is indeed known for its simpler deployment and reliance on traditional RAID levels (0, 1, 5, 6, 10) to protect against disk failures within a single controller or enclosure. Statement C correctly outlines the taxonomy of centralized storage, distinguishing between file-level NAS and block-level SAN (which includes both FC and IP variants). Statement D accurately describes the core value proposition of distributed storage: its ability to scale out by adding more commodity hardware nodes. By spreading the storage load across a cluster, distributed storage eliminates the performance bottlenecks often found in centralized controllers and enhances system reliability through multi-replica or erasure coding mechanisms. In Huawei’s cloud solutions, distributed storage is the preferred architecture for large-scale resource pools because it ensures that performance scales linearly with capacity, providing the high availability and efficiency required for modern virtualized data centers.

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

FusionAccess consists of multiple components, each with different roles and data persistence requirements.

WI (Web Interface)stores configuration and user access information and supports backup.

VLB (Virtual Load Balancer)maintains configuration data that can be backed up.

vAG (Virtual Access Gateway)also stores configuration-related data that supports backup and recovery.

TheLicensecomponent, however, isnot backed upas configuration or system data. Licensing information is typically re-imported or reactivated during recovery rather than restored from backup.

Therefore, the component that doesnothave backup data isLicense.

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.

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.

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 FusionCompute virtual networking, VMs in thesame network segment and same port groupshould be able to communicate normally.

OptionAis a possible cause. Host-based or VM-based firewalls may block traffic between virtual machines.

OptionCis also a possible cause.Security groupscan apply access control rules that isolate VMs, even within the same subnet.

OptionDis a possible cause. Faulty virtual NICs or driver issues can prevent network communication.

OptionBisnota possible cause. If both VM NICs are connected to thesame port group, they should be able to communicate, assuming no other restrictions exist.

Therefore, the correct answer isB.

In 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.

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.

The HCIA–Cloud Computing syllabus explains that routers are responsible forinter-network communicationand packet forwarding based onIP addresses. In the TCP/IP reference model, this function corresponds to theNetwork layer.

Routers analyze the destination IP address of a packet and use routing tables and routing protocols to determine thebest pathfor forwarding the packet to its destination. This behavior is distinct from switches, which forward frames based on MAC addresses at the data link layer.

TheData link layer (A)is associated with switches, theTransport layer (D)handles end-to-end communication (such as TCP and UDP), and theApplication layer (C)provides services to applications.

Therefore, according to HCIA–Cloud Computing network fundamentals, the correct answer isNetwork layer.

According to the official Huawei FusionAccess component deployment guidelines, the statement is FALSE. In the Huawei HCIA-Cloud Computing V5.5 curriculum, the deployment modes for infrastructure components are highly flexible to accommodate different business scales.

In adistributed deployment(large scale), it is a best practice to keep roles separate for performance and security. However, in astandalone or small-scale deployment, Huawei explicitly supports and even provides a "vAG/vLB/WI" all-in-one template. In this scenario, theWeb Interface (WI),Virtual Access Gateway (vAG), andVirtual Load Balancer (vLB)are all co-deployed on the same Virtual Machine. This reduces the hardware resource footprint and simplifies the management of the desktop cloud for small offices or testing environments.

ThevLB (Virtual Load Balancer)is responsible for distributing traffic among multiple WI servers to ensure high availability. ThevAG (Virtual Access Gateway)handles the secure HDP protocol traffic from the terminal to the desktop VM. TheWIprovides the login portal. Because these three roles interact directly during the user's login and desktop connection phase, they are technically compatible for co-residency on a single Linux-based appliance.

While the statement correctly identifies that vAG and vLB can be co-deployed (a very common practice), it incorrectly claims that vLB and WIcannotbe co-deployed. In the HCIA exam, it is important to remember that Huawei's "Standalone" deployment mode allows for the consolidation of these specific access-layer components into a single VM to maximize resource efficiency. Therefore, the assertion that such a deployment is impossible is technically incorrect.
