You are the server administrator for SRV05 which is a Windows Server 2003 Standard Edition file
server in your domain. Your backup strategy utilizes one full backup and then daily differential
backups. SRV05 has eight 72GB SCSI3 10,000RPM drives in an external drive array for data and
are set up using hardware RAID 5. SRV05 also has two additional 72GB SCSI3 10,000RPM
drives internal to the system and they are configured in a RAID 1 arrangement. This volume holds
the system and boot partitions for the server’s operating systems and a small amount of local
application data.
The full back up is performed each Saturday at 9:00PM EST. The full back up takes 2 hours. The
daily differential backups are performed each day at 9:00PM, Monday through Friday. There is no
full backup nor differential backup performed on Sunday. The amount of time needed for the
differential backups varies but it is never less than 20 minutes and the maximum time never
exceeds 75 minutes.
DNS07 has a hard disk failure in the external array at approximately 6:00PM on a Saturday. At
7:20PM a second drive in the external array also fails. What needs to be done to bring the server
back to working order so that users can access the data on the server?
Select the best answer.

A.
The failed drives need to be replaced and the data needs to be restored from the full backup.

B.
The failed drives need to be replaced and the data needs to be restored from the full backup
and all of the differential backups.

C.
The failed drives need to be replaced. Nothing additional needs to be done because the RAID
configuration allows the system to continue to run.

D.
The failed drives need to be replaced and the data needs to be restored from the full backup
and the last differential backup.
