Mark works as a Network Administrator for Technet Inc. The company has a Windows 2003 domainbased network. The network has a file server that uses a RAID-5 volume. The RAID-5 volume is
configured with five hard disk drives. Over the weekend, a drive in the RAID-5 volume fails. What will
Mark do to restore the RAID-5 volume?

A.
Replace the failed drive with a new one, use FDISK, select a new area of free space, and then
regenerate the volume.

B.
Replace the failed drive with a new one, use Disk Management, select a new area of free space,
and then regenerate the volume.

C.
Use Disk Management, select the failed drive, and then regenerate the volume.

D.
Use FDISK to delete the RAID-5 volume, and then restore data from the tape backup.

Explanation:
In order to restore the RAID-5 volume, Mark will have to replace the failed drive with a new one, use
Disk Management, select a new area of free space, and then regenerate the volume.
When a member of a mirrored volume or a RAID-5 volume fails, it becomes an orphan. Data for the
orphaned member can be regenerated from the remaining members. A new area of free space that
is of the same size or larger than the other members of the RAID-5 volume should be selected in Disk
Management and then the data should be regenerated. The fault-tolerance driver reads the
information from the stripes on the other member disks, and then re-creates the data of the missing
member and writes it to the new member on restarting the computer.
The volume must be locked by the operating system to regenerate a RAID-5 volume. All network
connections to the volume will be lost when a volume is regenerated.
