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

The HCIA–Cloud Computing syllabus clearly defines the basic terminology used in virtualization.

OptionAis correct. Aguest OSrefers to the operating system installed and running inside a virtual machine.

OptionBis correct. Aguest machineis another term for a virtual machine (VM).

OptionCis correct. Ahost machinetypically refers to thephysical serverthat provides hardware resources for virtualization.

OptionDis false. Ahost OS is not the virtualization software layer. The virtualization layer is thehypervisor(such as KVM, Xen, or FusionCompute). In some architectures, the host OS and hypervisor may coexist, but they arenot the same concept.

Therefore, the false statement isD.

According to the Huawei HCIA-Cloud Computing curriculum regarding Open Source Virtualization, statement D is FALSE. Libvirt is famously an open-source toolkit and API, licensed under the LGPL. It was specifically designed to provide a stable, long-term abstraction layer for managing different virtualization technologies. It is not a proprietary or "closed-source" product. In fact, its open nature is what allowed it to become the industry standard for managing Linux-based hypervisors.

The other statements accurately describe Libvirt's role in a cloud environment. As noted in statement A, Libvirt is "hypervisor-agnostic," meaning it can manage multiple types of virtualization, including KVM, Xen, QEMU, and even LXC containers. This allows management tools to use a single set of commands regardless of the underlying technology. Statement B is correct because Libvirt provides bindings for numerous programming languages, such as Python, C, and Java, enabling developers to automate VM lifecycle management (start, stop, migrate, snapshot) directly through code. Statement C is also true; Libvirt is essentially a collection of library functions and a daemon (libvirtd) that higher-level management platforms, such as Huawei'sFusionComputeor the open-sourceOpenStack, invoke to communicate with the hardware.

In Huawei's virtualization architecture, Libvirt acts as a crucial middle layer. By using the virsh command-line tool (which is part of the Libvirt package), administrators can perform complex VM operations without needing to understand the specific, low-level command syntax of each different hypervisor. Understanding that Libvirt is open-source and provides this universal management interface is a key learning point for the HCIA exam.

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

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.

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.

FusionAccess defines clear behaviors for desktop service adjustment:

Bis true. After reassignment, the systemautomatically starts the desktop, and a short wait time is required before user login.

Dis true. When a desktop assigned to a single user is unassigned, the systemautomatically shuts it downto save resources.

Ais false. Desktops assigned to multiple users or desktop groupscan be reassignedafter being unassigned.

Cis false. After unassignment, a desktop can beassigned to a different user, not only the original one.

Thus, the correct answers areB and D.

In the official Huawei HCIA-Cloud Computing curriculum, the OS is described as the bridge between hardware and software, with the kernel serving as its most critical component. The statement is TRUE because the kernel acts as the core manager of all physical resources, including the CPU, memory, and I/O devices. When an upper-layer application needs to perform a task—such as reading a file from a disk or sending data over a network—it cannot access the hardware directly. Instead, it must send a request to the kernel through a System Call Interface.

The kernel operates in a protected "Kernel Mode," while applications run in "User Mode." This separation ensures system stability and security. By managing resource scheduling, the kernel ensures that multiple applications can run concurrently without interfering with each other's memory space or crashing the entire system. In a virtualization context, the role of the kernel becomes even more significant. For instance, in Huawei’s KVM-based virtualization, the Linux kernel itself is transformed into a Hypervisor. The kernel's ability to manage CPU and memory is extended to create virtualized versions of these resources for Virtual Machines (VMs).

The Huawei training documentation highlights that the efficiency of the kernel directly impacts the performance of the cloud platform. Because the kernel handles process management, memory allocation, and the file system, any optimization at the kernel level results in better VM density and lower latency for cloud services. Therefore, understanding the kernel's role as both a resource manager and a provider of the system call interface is fundamental for any ICT associate working with Huawei FusionCompute or FusionAccess solutions.

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

As detailed in the Huawei FusionAccess documentation for the HCIA curriculum, the Huawei Desktop Protocol (HDP) is designed to optimize the user experience in Virtual Desktop Infrastructure (VDI). Statement A is correct: HDP features "Intelligent identification of video data."8 The protocol can automatically distinguish between standard GDI (Graphics Device Interface) desktop elements and active video streams.9 When video is detected, HDP switches to specialized compression algorithms (such as H.264 or H.265) to ensure efficient encoding and reduced bandwidth consumption.

Statement B is also a verified function. HDP employsDynamic Frame Rate Adjustment.10By monitoring the network quality (latency and packet loss) in real-time, the protocol can adjust the frame rate (e.g., from 60fps down to 30fps or lower) to maintain a smooth, jitter-free playback experience even on unstable or low-bandwidth links. Statement C is true as HDP supports multiple rendering modes. In "Multimedia Redirection," the video stream is decoded on theclientside (using local hardware acceleration), while in other modes, decoding occurs on theserver(VM) with the resulting images sent to the client. This dual-support flexibility ensures compatibility across various terminal types.

Statement D isincorrectbecause of the "maximum of 2K videos" limitation. According to the official HCIA-Cloud Computing V5.5 and FusionAccess technical guides, HDP@Media technology (multimedia redirection) explicitly supports4K UHDvideo playback, not just a maximum of 2K. While D correctly mentions "automatic reconnection" and "dynamic traffic adjustment," the resolution limit is technically outdated for the current Huawei cloud ecosystem. Thus, for the purposes of the HCIA certification, only A, B, and C are fully accurate representations of HDP's high-fidelity audiovisual capabilities.

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.

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 FusionCompute architecture, thehost OSrefers to the operating system running on thephysical compute node.

TheCompute Node Agent (CNA)is the component deployed on the physical server. It integrates the host operating system and hypervisor, directly managing hardware resources and providing virtualization services.

Linux VM (A)refers to the guest OS running inside a virtual machine.

VRM (B)is the centralized management component.

VNA (C)is responsible for virtual networking services.

Therefore, the host OS runs within theCNA, makingDthe correct answer.
