An administrator wants to create a master copy of an existing virtual machine (VM) named "TestApp" and deploy VMs from this master copy whenever a user requests one. Which method can the administrator

Deploying from an Open Virtual Machine Format (OVF) template is used to create a VM from a pre-packaged OVF file, not to create a master copy from an existing VM.

Converting a template to a VM is the reverse operation, changing a template into a functional virtual machine, not creating a master copy.

Cloning the virtual machine (VM) to a template allows an administrator to create a non-runnable, master copy of the VM's configuration and virtual disks. This template can then be used repeatedly to deploy new, identical virtual machines, serving as the desired 'master copy'.

Creating a new VM involves building a virtual machine from scratch, which does not utilize an existing 'TestApp' VM as a master copy.
