Answer: C

Explanation:

Issue

One or more virtual hard disks have a physical sector size that is smaller than the physical sector size of the storage on which the virtual hard disk file is located.

Resolution

Do one of the following:

The Set-VHD cmdlet sets the ParentPath or PhysicalSectorSizeBytes properties of a virtual hard disk. The two properties must be set in separate operations.

The Set-VHD -PhysicalSectorSizeBytes parameter specifies the physical sector size, in bytes. Valid values are 512 and 4096. This parameter is supported only on a VHDX-format disk that is not attached when the operation is initiated.
