Which of the following statements aretrueabout deploying Compute Node Agent (CNA) and Virtual Resource Management (VRM) in Huawei FusionCompute?
A.
CNA can be deployed on virtual machines or physical servers.
B.
If the VRM nodes are deployed on physical servers, the active and standby VRM nodes must be deployed on two physical servers.
C.
If the VRM nodes are deployed on virtual machines, you need to select two hosts in the management cluster and deploy the active and standby VRM VMs on these hosts.
D.
VRM can be deployed on virtual machines or physical servers.
In FusionCompute architecture,CNAandVRMhave clearly defined deployment models.
OptionAis false.CNA is deployed only on physical servers(compute nodes). It is responsible for interacting directly with hardware resources and cannot run inside a VM.
OptionBis true. When VRM is deployed on physical servers,active and standby VRM nodes must be installed on separate physical serversto ensure high availability.
OptionCis true. When VRM is deployed on virtual machines, the active and standby VRM VMs must be placed ondifferent hosts within the management clusterto avoid single points of failure.
