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?

What actions will the cluster automatically take?
When a node fails within a Nutanix AHV-based 10-node cluster, all HA-protected VMs will be automatically restarted on other nodes in the cluster. This ensures that there is minimal interruption to the services provided by these VMs and maintains high availability within the cluster. This process does not require user intervention and happens automatically to preserve the continuity of operations.
If a node fails, all HA-protected VMs can be automatically restarted on other nodes in the cluster. End users will see that their application is unavailable during the time that the VMs are restarted on other hosts. https://next.nutanix.com/how-it-works-22/how-nutanix-handles-failures-node-failure-39369

When a node fails within a Nutanix AHV-based cluster, the cluster will automatically take the following actions: Data Redistribution: The cluster redistributes data from the failed node to other healthy nodes. This ensures data availability and maintains redundancy. VM Failover: VMs running on the failed node are automatically restarted on other nodes. VM failover ensures continuity of services. Self-Healing: Nutanix Prism detects the failure and initiates self-healing processes. It may replace the failed node with a spare node (if available). Rebalancing: The cluster rebalances resources (CPU, memory, storage) across remaining nodes. This optimizes performance and maintains balanced utilization. Remember that Nutanix AHV clusters are designed for high availability and resilience, minimizing impact during node failures. (D. Correct answer).
Only HA protected vms
D - Nutanix supports high availability (HA) for VMs by automatically restarting them on other nodes in the cluster in case of a node failure. The cluster CPU and memory utilization will increase temporarily until the failed node is recovered, but there will be no user impact.

correct answer
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.
