Nutanix Certified Associate Practice Exam

What action can help restore normal operations in a Nutanix cluster after a block power failure?

1. Resetting the cluster credentials

2. Restoring the cluster from backup

3. Allowing the affected VMs to restart

4. Reconfiguring the block settings

The correct answer is: Allowing the affected VMs to restart

Restoring normal operations in a Nutanix cluster after a block power failure primarily involves allowing the affected virtual machines (VMs) to restart. When a block power failure occurs, it typically impacts the running state of the VMs within the cluster. Once power is restored, the virtualization layer will attempt to automatically start the VMs that were affected by the power loss. This process is crucial because the VMs rely on the underlying infrastructure provided by the Nutanix cluster. By allowing the affected VMs to restart, you can bring them back online and resume their operations, minimizing downtime and restoring services quickly. It's important to note that the Nutanix architecture is designed to manage VM restarts efficiently after such events, ensuring that workloads resume as expected. The other options, while they may have their places in different contexts, do not directly address the immediate need to restore operations after a power failure. Resetting cluster credentials may be necessary for administrative access but has no effect on VM state. Restoring from backup is a more involved process that deals with data loss and typically occurs after a failure that affects data integrity. Reconfiguring block settings is usually a maintenance task rather than an immediate response to a power-related incident.
