Which utility should you use?

You recover from the crash of a mirrored boot drive and now you need to reestablish the
mirror. Which utility should you use?

A.
Windows NT backup.

B.
Disk administrator.

C.
Windows NT diagnostics.

D.
Server manager.

Explanation:
Disk Administrator is used to create, break, and reestablish mirrors.
It is also used to create other RAID file systems, such as striping and striping with
parity.
Incorrect Answers:
A: Windows NT Backup is the backup/restore utility to backup and restore data. The utilityis not
deigned to restore the internal file structure, and cannot fix the mirror. As a matterof fact, the mirror

is transparent to the utility, and Windows NT Backup is not evenaware that the mirror even exists.
C: Windows NT Diagnostics, a newer version of the MSD.EXE (Microsoft Diagnostics)program, is
a display only utility that provides information on hardware resources,including memory, IRQs, and
port assignments. It may provide information on the diskresources, but is not aware of mirroring,
nor can it be used to repair a broken mirror.
D: Server Manager is used to manage the server. Mirroring is on the file system level,and is below
the services operating on the server. Server Manager does not deal with lowlevel fie systems, and
cannot be used to repair a broken mirror.
