70-687 Configuring Windows 8.1 – sample exam – Q68

A client computer that runs Windows 8.1 has two hard disk drives: a system drive and a data drive.

You are preparing to back up the computer prior to installing a developing software product.

You have the following requirements:
The system disk that is part of the backup must be mountable from within Windows.
The system disk that is part of the backup must be bootable.
The backup must be viable to restore in the event of a hard disk failure.
The backup must contain data from both hard disk drives.

You need to select a backup method.

Which method should you use?

A. System repair disk
B. Storage pool
C. System image
D. File History

Correct Answer: C
DISM Image Management Command-Line Options
Deployment Image Servicing and Management (DISM.exe) mounts a Windows image (.wim) file or virtual hard disk (.vhd or .vhdx) for servicing. You can also use the DISM image management command to list the image index numbers, to verify the architecture for the image that you are mounting, append an im- age, apply an image, capture an image and delete an image.

Further Information: Follow-up On Backups: Mounting a System Image

Yesterday, I posted about my practice of using the built in system image creation tools in Windows 7 and Windows 8 to create a backup of my system whenever I’m getting ready to upgrade.

Now, if something goes tragically wrong, I can just boot to a system repair disk, and restore the image, and I’m back to where I started. But let’s suppose the install goes fine, but I find that there’s a file I need to get to from my backup, but I don’t want to restore the entire backup, just get that file.

The good news is that you can do this easily, because the system image is stored as a .vhd (or in the case of Windows 8, a .vhdx) file. And Windows 8 can mount a VHD as a drive, making it easy to access the files from the backup.

Just plug in the external drive you used for your backup, and find the WindowsImageBackup folder (should be at the root of the drive), and inside it find the folder matching the name of the machine you backed up. Inside that should be a folder that starts with “Backup” and the date of the backup. And finally, inside the backup folder is a .vhd (or .vhdx) file containing the backup of your system (you might see more than one .vhd(x)…if so, look for the largest one, as shown in the image below):


If you right-click that file and select “Mount” (as shown below) Windows will mount the VHD file for you, and assign it a drive letter.
