The Resize-VHD cmdlet resizes a virtual hard disk. This cmdlet lets you shrink or expand the size of a virtual hard disk, but the shrink operation is allowed only on VHDX virtual hard disks. The shrink operation fails if it would shrink the virtual disk to less than its minimum size (available through the VHDX object’s MinimumSize property).
Never mind, D is correct.”the shrink operation is allowed only on VHDX virtual hard disks” thus the .vhd must be converted first.
The answer is A, Dismount-VHD. Convert-VHD will throw an exception if the source VHD is mounted. The correct sequence of events is:
A: Dismount-VHD
D: Convert-VHD
C: Resize-VHD
B: Mount-VHD
Agree with Gordon Freeman
Resize-VHD is an offline operation; the virtual hard disk must not be attached when the operation is initiated. Therefore we must dismount the vhd first
The shrink operation is allowed only on VHDX virtual hard disks. Therefore we must convert the vhd to vhdx
then resize
then mount again
