An administrator is asked to copy a single hard disk from one datastore to another. Which virtual machine Hie type should the administrator select?

The .vmdk file is the primary file that represents a virtual machine's hard disk, containing all the data, operating system, and applications. When an administrator needs to copy a virtual hard disk, they must select this specific file type.

The .vswp file is a virtual machine swap file, created when a VM powers on, and is used for memory paging, not for storing the virtual hard disk content.

The .vmx file is the virtual machine's configuration file, defining its hardware and settings, but does not contain the actual disk data.

The .vmss file is a virtual machine suspend state file, created when a VM is suspended, and does not represent the virtual hard disk.
