Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
You have a Hyper-V host named Server1 that runs Windows Server 2016. Server1 has a dynamically expanding virtual hard disk (VHD) file that is 900 GB. The
VHD contains 400 GB of free space.
You need to reduce the amount of disk space used by the VHD.
What should you run?

A. the Mount-VHD cmdlet
B. the Diskpart command
C. the Set-VHD cmdlet
D. the Set-VM cmdlet
E. the Set-VMHost cmdlet
F. the Set-VMProcessor cmdlet
G. the Install-WindowsFeature cmdlet
H. the Optimize-VHD cmdlet

Show Suggested Answer

Suggested Answer: H 🗳️
The Optimize-VHD cmdlet optimizes the allocation of space in or more virtual hard disk files, except for fixed virtual hard disks. The Compact operation is used to optimize the files. This operation reclaims unused blocks as well as rearranges the blocks to be more efficiently packed, which reduces the size of a virtual hard disk file.

ok, agreed, you must first mount the vhd, but thats not what has been asked. the question is: You need to reduce the amount of disk space used by the VHD., What should you run? Does Mount-vhd the amount of disk space? So answer is correct, Optimize-vhd
