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.
