第1题：

You are the network administrator for Ezonexam.

Your Windows 2000 Server computer named Ezonexam1 contains two 36-GB hard disks. Disk 0 and Disk 1. Each disk is configured as a basic disc and has a single 36-GB NTFS partition. Both partitions are backed up to a tape each night. The partition on Disk 1 stores user data. Most users at Ezonexam encrypt their files. Disk 1 fails. You replace it with a new hard disk and create a single NTFS partition.

You need to recover the data as quickly as possible while maintaining the security of the files on Disk 1.

What should you do?

A．Restore the contents of Disk 1 from the most recent tape backup to a second file server. Instruct users to copy their files from the second file server to the new partition.

B．Restore the contents of Disk 1 from the most recent tape backup to a second file server. Log on to Ezonexam1 console as a recovery agent. Copy the files from the second file server to the new partition.

C．Restore the contents of Disk 1 from the most recent tape backup to the new partition on Ezonexam1. Instruct the users to verify the integrity of their files.

D．Restore the contents of Disk 1 from the most recent tape backup to the new partition on Ezonexam1. Run the cipher command to decrypt the files.
