VMware vSphere 7.x Professional for Service Providers — Question 10

In a vSphere HA enabled cluster, what happens if the master host is unable to communicate with a slave host over the management network?

Answer options

• A. The master host uses datastore heartbeating.
• B. VMs are rebooted by vSphere HA.
• C. The host is dropped from the cluster.
• D. A new master host is elected.

Correct answer: B

Explanation

When the master host cannot communicate with a slave host, vSphere HA will automatically reboot the virtual machines on the affected host to ensure availability, which is why option B is correct. The other options do not accurately describe the response of vSphere HA in this situation; datastore heartbeating is a fallback mechanism but does not lead to VM reboots, and hosts are not dropped or new masters elected simply due to communication loss.
