An administrator receives an alert that a node has failed within a Nutanix AHV-based 10-node cluster.

Before the failure, the cluster CPU and memory utilization was around 50%.

What actions will the cluster automatically take?

A.
VMs will be unavailable until the affected host is fully functional.

Answers
D.
All HA-protected VMs will be automatically restarted on other nodes in the cluster.
Suggested answer: D

Explanation:

In a Nutanix AHV-based cluster, if a node fails, the cluster will automatically take actions to ensure high availability of the virtual machines. The cluster will automatically live migrate the VMs running on the failed node to other healthy nodes in the cluster without any user impact, this process is known as "Failover" . The live migration process ensures that the VMs are restarted on another node in the cluster as soon as possible with minimal interruption to the users. The cluster

CPU and memory utilization being around 50% at the time of failure does not affect the failover process.
