A single host in a four-node AHV-based cluster experiences a complete network failure.
If more than enough resources exist in the cluster to tolerate a node failure, what happens to the user VMs running on that host?

In a Nutanix AHV-based cluster, if a single host experiences a complete network failure but the cluster has enough resources to tolerate a node failure, the user VMs running on that host will automatically restart on the remaining three hosts. This ensures that the VMs remain operational even in the event of such a failure.

C. VMs automatically restart on the three remaining hosts.
C. VMs automatically restart on the three remaining hosts.
It has to be C. The correct answer is showing as D but how are VMs going to live migrate when the node has suffered complete network failure!
C. If there is a complete network failure on a single host, it cannot be seen by the other nodes in the cluster. At that point it would be treated as a failed host and any HA VMs would be rebooted onto one of the other nodes.
