A number of users are indicating that access to a network file server is responding very slowly when reading or writing to the share. The server administrator notes that a drive has failed in a

four-disk RAID 5 array. The array is running in a degraded state because no hot spare was configured. After replacing the failed disk, which of the following steps would be BEST to take to prevent slow response after a drive failure?

A. Add a drive to th

e array, but do not configure it as a hot spare.

B. Add an additional hard drive, and convert the volume to a RAID 6 configuration.

C. Add an additional hard drive, and convert the volume to a RAID 10 configuration.

D. Add a drive to the array, and configu

re it as a cold spare.
