• A Prism alert reports a CVM health issue on node-3, while the AHV host remains powered on and reachable. The cluster is otherwise stable, and the CVM process is not running on that node. Which condition best explains the alert?
• A Nutanix cluster raises an alert stating that a disk has failed and data resiliency is at risk. How should an administrator classify this alert, and why?

What should you check first to confirm the cause of this flat IOPS pattern?
• During the first 15 minutes of a nightly reporting job, an AHV VM shows high IOPS and low latency. After that window, IOPS drop to a flat ceiling and disk latency rises, while host CPU, CVM CPU, storage container health, and memory pressure remain normal. Which cause should you investigate first?

The administrator must prevent the action from executing until an authorized operator explicitly approves it, while keeping the playbook event-driven. How should the playbook be designed?
• You create an X-Play playbook in Prism Central. Step 1 discovers a VM UUID from a cluster query, and step 2 must use that UUID to power off the VM. How should the discovered identifier be carried between the steps?
• Your team must automate a weekly shutdown and startup of a set of AHV VMs in Prism Central. The workflow should be centralized, supported, and avoid custom scripts or node-level commands. Which approach should you use?
