On may 11, at 9:30 A.M., an administrator accidentally removes several critical files
from /etc. Analysis of the /etc/dumpdates file reveals the following:
/dev/rdsk/c0t0d0s0 0 Fri May 10 10:15:38 2002
/dev/rdsk/c0t0d0s5 0 Fri May 10 10:46:06 2002
/dev/rdsk/c0t0d0s7 0 Fri May 10 10:54:56 2002
/dev/rdsk/c0t0d0s7 0 Fri May 10 10:59:02 2002
/dev/rdsk/c0t0d0s0 2 Sat May 11 10:15:03 2002
/dev/rdsk/c0t0d0s7 2 Sat May 11 10:25:23 2002
/dev/rdsk/c0t0d0s0 3 Sun May 12 10:15:14 2002
/dev/rdsk/c0t0d0s7 3 Sun May 12 10:22:22 2002
A portion of the /ect/vfstab file shows:
/dev/dsk/c0t0d0s0 /
/dev/dsk/c0t0d0s5 /opt
/dev/dsk/c0t0d0s6 /usr
/dev/dsk/c0t0d0s7 /export/home
Which /etc/dumpdates entry identifies the tape from which you should obtain the deleted files?

A.
/dev/rdsk/c0t0d0s0 3 Sun May 12 10:15:14 2002

B.
/dev/rdsk/c0t0d0s0 0 Fri May 10 10:15:38 2002

C.
/dev/rdsk/c0t0d0s6 0 Fri May 10 10:54:56 2002

D.
/dev/rdsk/c0t0d0s5 0 Fri May 10 10:46:06 2002

Explanation:

The /etc directory will be contained on the root ( / ) file system.
The last backup of the root file system (/dev/dsk/c0t0d0s0) was on May 11 at 10:59, Which was after the deletion of the files so, use the previous backup on May 10 at 10:15
