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.

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.

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

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.

According to the Huawei HCIA-Cloud Computing documentation, FusionAccess application policies are critical for tailoring the virtual desktop experience to specific security and performance requirements. The Huawei Desktop Protocol (HDP) management interface allows administrators to configure granular controls over data flow, display quality, and session behavior.

For Scenario 1, setting Clipboard Redirection to " Client to Server " ensures a one-way data flow. This allows users to copy text or files from their local physical client into the virtual machine (VM) while preventing the extraction of data from the VM back to the local device, thus protecting sensitive corporate information. In Scenario 2, the Display Policy Grade determines the balance between visual fidelity and network consumption. Grade 5 is the highest setting, designed for high-performance networks (25 Mbit/s or higher), and is optimized for server-side video decoding to provide the best possible playback quality.

Scenario 3 addresses security during periods of inactivity. By enabling the " Automatic Screen Lock " under the Session policy, the system monitors user input and automatically secures the desktop if no activity is detected within the specified interval (such as 10 minutes), preventing unauthorized access to an unattended terminal. Finally, Scenario 4 utilizes File Redirection to control external hardware access. By setting this policy to " Read-only " and enabling " Client Removable Driver, " users can view and open files stored on their local USB flash drives within the VM environment but are strictly prohibited from saving or modifying any data back onto those physical devices. These configurations demonstrate the robustness of Huawei’s VDI policy engine in balancing user productivity with stringent security protocols.
