What should you do?

You have a computer that runs Windows 7. Your computer s disk configuration is shown in the exhibit. (Click the Exhibit button.) You need to ensure that you can create a striped volume on the computer. What should you do?

A.
Add an additional hard disk.

B.
Convert all disks to dynamic disks.

C.
Install a digitally-signed disk driver.

D.
Set the Startup Type of the Virtual Disk Service (VDS) to Automatic.

Explanation:
Managing Disk Volumes
Windows 7 enables you to expand and contract volumes without data loss and without requiring a reboot. You can create simple volumes, spanned volumes, striped volumes, mirrored volumes, and striped volumes with parity on dynamic disks. You can also create simple volumes on basic disks.
Creating a Striped Volume (RAID-0)
A striped volume uses the free space on more than one physical hard disk to create the volume. It enables the operating system to write across all disks in small blocks, or stripes, distributing the load across the disks in the volume. Data is written to a stripe on the first disk, the next block of data is written to a stripe on the next disk, and so on. The data can be split into stripe-sized blocks and written to all the disks in the stripe set simultaneously. A striped (RAID-0) volume requires at least two disks.
When data is read from the volume, it can be accessed simultaneously on all the disks in the volume. RAID-0 therefore significantly improves both read and write performance. The portions of disk used to create the volume need to be the same size; the size of the smallest free space included in the striped volume is the determinant. A striped volume is not fault-tolerant. If one disk fails, the entire volume fails.
