Which of the following descriptions about the functions of the CNA module in Huawei FusionCompute is wrong?

Question

Options

• AProvide virtual computing capabilities
• BDynamic adjustment of resources in the management cluster
• CManage computing, storage, and network resources on computing nodes
• DManage virtual machines on compute nodes

• A
  15% (5)
• B
  3% (1)
• C
  73% (24)
• D
  9% (3)

Explanation

Option C incorrectly attributes comprehensive resource management - covering computing, storage, and network - to the CNA module. That responsibility belongs to the VRM (Virtualization Resource Manager), which operates at the cluster management level and handles unified resource scheduling and allocation across the entire FusionCompute environment.

Why the distractors are correct descriptions of CNA:

• A is a true CNA function: CNA runs on each physical compute node and delivers virtual computing capabilities through hypervisor-level virtualization.
• B is also accurate: CNA participates in dynamic resource adjustment within the management cluster, responding to scheduling decisions.
• D is a core CNA responsibility: CNA directly manages the lifecycle and operation of virtual machines residing on its compute node.

Memory tip: Think of CNA = Compute Node Agent - it lives on the node and handles the VMs on that node. Anything involving cross-node, storage-wide, or network-wide management belongs to the VRM above it. If an answer says CNA manages all three resource types (compute + storage + network), that's VRM's job, not CNA's.
