Which action would allow the VM to power on?

An administrator is attempting to power on a virtual machine with 32GB of memory. The operation fails with the following error:

Could not power on VM: No space left on device

Checking the space on the virtual machine’s datastore, there is 30GB free.

Which action would allow the VM to power on?
A . Set a 2GB memory reservation on the V
C . Mount the virtual disk from the affected VM on to another virtual machine and free up space from within the O
E . Enable vSphere HD admission control on the cluster in which the VM resides.
F . Set a 2GB memory limit on the V

Answer: A

Explanation:

The swap file size can be calculated with the formula (.vswp File = Allocated Memory – Memory Reservation).

As per default, the reservation is set to 0, so the .vswp file size is equal to the amount of virtual memory.
