NEW QUESTION # 32
Which of the following descriptions about virtual machine high availability (HA) is correct?
- A. After the cluster enables the HA function, all virtual machines in the cluster have HA turned on, and the HA function of a single virtual machine cannot be turned off.
- B. HA functionality provides easy-to-use, cost-effective high availability for applications running on all virtual machines in the cluster.
- C. After the HA function is enabled, CVM will continuously monitor the operating status of all server hosts and virtual machines in the cluster. When a host or virtual machine fails, CVM will immediately respond and start all affected virtual machines on other available hosts in the cluster.
