The correct answer is C. Reduction of vCPU cannot be done on a VM with a running snapshot. The Playbook is designed to manually reduce the vCPU count on any selected VM within the environment. However, it failed during a test run on VM2 because there was a running snapshot of the VM. According to Nutanix Multicloud Automation (NCP-MCA) principles, you cannot reduce…
Question
Refer to the exhibit. An administrator created the Playbook shown in the exhibit to allow for manual reduction of vCPU count on any selected VM within their environment. During a test run of the play on one of the VMs running in development, the administrator ran into an error that the Playbook cannot be completed against the selected VM. Here are the details of the affected VM:
VM Name: VM2 vCPU: 4 RAM: 8 GB OS: Windows 2016 Hypervisor: AHV What caused this Playbook to fail?
Exhibit
Options
- AThis play cannot be executed against a VM on AHV.
- BThe VM needs to be powered off before vCPU can be reduced.
- CReduction of vCPU cannot be done on a VM with a running snapshot.
- DThe play will cause the VM to go below the minimum vCPU.

Explanation
The Playbook is designed to manually reduce the vCPU count on any selected VM within the environment. However, it failed during a test run on VM2 because there was a running snapshot of the VM. According to Nutanix Multicloud Automation (NCP-MCA) principles, you cannot reduce the vCPU count on a VM that has an active snapshot. This is because the snapshot captures the state of the VM configuration and data, and reverting to a snapshot will restore both the guest OS and the virtual hardware. Therefore, changing the vCPU count while a snapshot is running will cause inconsistency and error.
