What's incorrect in NUMA's description is ()

• A.Host NUMA guarantees VM access to local physical memory, reduces memory access latency, and can improve VM performance
• B.Guest NUMA is to identify the Guest OS and its internal applications by presenting the NUMA structure to the virtual machine.
  NUMA structure to achieve the purpose of improving application performance
• C.Host NUMA mainly provides a CPU load balancing mechanism to resolve VM performance bottlenecks caused by imbalanced CPU resource allocation.
• D.NUMA technology makes CPU access similar to the speed of memory in Node and the speed of access to memory in other Nodes
