Explanation:
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 FusionAccess, full copy desktops are created by completely copying the template into an independent virtual machine. After the VM is created, it no longer depends on the template.
According to HCIA-Cloud Computing materials:
Modifying or deleting a full copy template does not affect already provisioned desktops.
Only linked clone desktops depend on the template and snapshot chain.
Therefore, the statement is FALSE.

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.

According to the Huawei HCIA-Cloud Computing curriculum, the definition of centralized storage is centered on the unified management of hardware components. The statement is TRUE as it accurately describes the physical architecture of traditional SAN (Storage Area Network) and NAS (Network Attached Storage) systems. In a centralized model, the storage system typically consists of two main parts: the Controller Enclosure and the Disk Enclosure.
The controller enclosure is the "brain" of the storage system. It contains the controllers (usually in a redundant pair for high availability), cache, and interface modules. Its role is to process I/O requests from servers, manage RAID configurations, and handle advanced data features like snapshots or replication. The disk enclosures, on the other hand, are the physical "shelves" that house the actual Hard Disk Drives (HDDs) or Solid State Drives (SSDs). These enclosures are connected to the controller enclosure via high-speed backend cables (such as SAS).
In this centralized architecture, the physical disks are not "visible" to the hosts directly. Instead, the controller abstracts these physical disks into a storage pool and then intoLUNs (Logical Unit Numbers). These LUNs are then mapped to service hosts (servers) via the storage network (FC or IP). This design allows for high performance and centralized management, as administrators can monitor and configure the entire storage resource pool from a single interface (such as Huawei DeviceManager). This is the standard deployment model for mission-critical applications in a Huawei FusionCompute environment, ensuring that storage resources are consolidated, secure, and easily scalable by adding more disk enclosures.

(Note: The original question contained a typo. As requested, "host OS" has been corrected to "guest OS" because Linux, in this scenario, is the Guest operating system.) In the official Huawei HCIA-Cloud Computing curriculum, the architecture of a virtualized system is divided into the Host Machine and the Guest Machine. TheHost Machineis the physical server (hardware) and the virtualization software (CNA in FusionCompute). TheGuest Machineis the Virtual Machine (VM) created by the hypervisor. According to the training materials, theGuest OSis the operating system that is installed and executed within the virtualized environment of a VM.13 Therefore, if a VM running Linux is created, the Linux operating system is the Guest OS, and it runs specifically inside theLinux VM. The VM acts as a logical container that provides the Linux OS with virtualized CPU, memory, storage, and network resources.14From the perspective of the Linux OS, it believes it is running on a dedicated physical server, but in reality, it is encapsulated within the VM boundary provided by the CNA.
The other components mentioned have different roles:CNA (Computing Node Agent)is the "host" software that manages the hardware and hosts the VM, but the Linux OS does not run "in" the CNA directly; it runs in the VM managed by the CNA.VRM (Virtual Resource Management)is the management platform used by administrators to create and configure the VM.VNA (Virtual Node Agent)is a process within the CNA that handles management commands from the VRM. In the Huawei certification logic, it is crucial to distinguish between the "Container" (the VM) and the "Occupant" (the Guest OS). The Guest OS is always tied to the VM environment, which ensures logical isolation and mobility across the cloud infrastructure.
