QUESTION: 18

You are the server administrator for SRV05 which is a Windows Server 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.

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