An administrator needs to create a VM Template from an existing VM.

To create a VM template from an existing VM in Nutanix, the VM must be powered off. This ensures that the template is consistent and does not include any transient data or activity from the VM. Once the VM is powered off, the administrator can use the Prism UI to take a snapshot and designate it as a template.

A. Sysprep or Cloud-init script:These are optional for post-deployment configuration, not mandatory for creating a template.

B. The VM is powered on:This is incorrect, as the VM must be powered off.

C. Windows OS is installed:The OS type is irrelevant for creating a template.

D. The VM is powered off:Correct, as creating a template requires the VM to be in a powered-off state.
