A server named S1 contains a mirrored volume that consists of two 40 GB disks. It also contains a third unallocated dynamic disk. An application that currently requires 45 GB of disk space will be installed on S1. The application data for this application is expected to grow at a rapid rate. Which of the following should you do to allocate enough space for the anticipated application data and ensure that data will remain available in case of disk failure?
  1. Create a spanned volume.
  2. Create a RAID-5 volume.
  3. Create a stripped volume.
  4. Create a mirrored volume.
Explanation
Answer - B - To allocate enough space for the anticipated application data and ensure that data will remain available in case of disk failure, create a RAID-5 volume.

Key Takeaway: RAID level 5 provides fault tolerance with redundant technology and requires at least 3 hard drives. It stripes both data and parity information across three or more drives. The performance of a RAID 5 array can be adjusted by trying different stripe sizes until one is found that is well-matched to the application being used.
