As defined in the "Network Technology Basics" module of the HCIA-Cloud Computing training, a router is a Layer 3 (Network Layer) device responsible for interconnecting different network segments and selecting the optimal path for data packets. To perform this function, the router maintains and manages a Routing Table. This table is the "map" of the network that the router uses to make forwarding decisions. Every entry in the routing table typically includes several key parameters: the destination network address, the subnet mask, the protocol (how the route was learned, such as Static, OSPF, or BGP), the preference value, the cost (metric), and the next-hop address or outbound interface.

When a router receives an IP packet, it examines the destination IP address and performs a lookup in its routing table to find the most specific match (longest match rule). If a matching entry is found, the router encapsulates the packet into a new frame and sends it toward the next hop. If no match is found and no default route exists, the packet is discarded. This process is fundamental to the operation of a Cloud Data Center where multiple Virtual Private Clouds (VPCs) and subnets must communicate through virtual or physical routers.

While a switch manages a MAC address table to forward frames at Layer 2, and a host manages an ARP table to map IP addresses to MAC addresses, only the routing table provides the cross-network path intelligence required for routing. In Huawei’s virtualization solutions, virtual routers within the software-defined networking (SDN) layer use these same logic principles to ensure that traffic between virtual machines in different subnets is directed efficiently to the correct destination. Proper management of the routing table is therefore the cornerstone of network reachability in cloud environments.

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, specifically the "FusionAccess Planning and Deployment" section, the statement is TRUE. When an enterprise scales its desktop cloud across multiple regions or deploys separate FusionAccess environments (each with its own ITA/HDC/DB set), there is often a requirement to share a single license pool to optimize costs and management.

In a standard small-scale deployment, the License component is typically co-deployed with theITA (IT Adapter). However, if multiple independent FusionAccess systems (different clusters or management sets) need to draw from the same license file, the License component must be "de-coupled" from any specific ITA anddeployed independentlyas a standalone service. This standalone License Server acts as a centralized repository that tracks the total number of permitted desktop users or VMs. Each FusionAccess system is then configured to point to this central server's IP address.

This independent deployment model ensures that license seats are not "trapped" in one specific system. For example, if System A has 500 licenses but only 200 active users, and System B is at its limit, a centralized license server allows System B to utilize the excess capacity. This flexibility is a core architectural principle in Huawei’s large-scale VDI solutions. During deployment planning, administrators must decide whether to use a local license (co-deployed) or a centralized license (independent). For multi-system environments, the independent deployment is the official Huawei recommendation to ensure proper license reconciliation and to prevent "over-use" or "under-use" of purchased ICT assets across the enterprise.

In Linux-based virtualization environments, aTAP deviceis a software-based virtual network interface that operates atLayer 2of the OSI model.

TAP devices are independently maintained by the Linux kernel and are commonly used to connect virtual machines to virtual switches or bridges. They simulate physical Ethernet interfaces, allowing VMs to send and receive Ethernet frames.

This definition aligns with HCIA–Cloud Computing networking fundamentals, so the statement isTRUE.
