What should you do?

Your network contains a server named Server1 that has two volumes named C and D.
You add a new volume.
You need to ensure that you can access data on the new volume by using the path D:data.
What should you do?

A.
From Disk Management, create a volume mount point.

B.
From Disk Management, attach a virtual hard disk (VHD).

C.
At the command prompt, run the diskraid.exe command and specify the /v parameter.

D.
At the command prompt, run the dism.exe command and specify the /mount-wim parameter.

Explanation:
Assign a mount point folder path to a drive
You can use Disk Management to assign a mount-point folder path (rather than a drive letter) to the drive. Mount-point folder paths are available only on empty folders on basic or dynamic NTFS volumes.
Backup Operator or Administrator is the minimum membership required.
Assigning a mount-point folder path to a drive
1. In Disk Manager, right-click the partition or volume where you want to assign the mount-point folder path, and then click Change Drive Letter and Paths.
2. Do one of the following:
* To assign a mount-point folder path, click Add. Click Mount in the following empty NTFS folder, type the path to an empty folder on an NTFS volume, or click Browse to locate it.
* To remove the mount-point folder path, click it and then click Remove.
Additional considerations
* If you are administering a local or remote computer, you can browse NTFS folders on that computer.
* When assigning a mount-point folder path to a drive, use Event Viewer to check the system log for any Cluster service errors or warnings indicating mount point failures. These errors would be listed as ClusSvc in the Source column and Physical Disk Resource in the Category column.
