Exam Prep Practice Questions
Question 1
Which of the following can be backed up using the
ufsdump
command?
[Select all that apply.]
❑
A.
File systems on hard disks
❑
B.
Files on hard disks
❑
C.
File systems on CD-ROMs
❑
D.
Directories on hard disks
The correct answers are A, B, and D. File systems on CD-ROMs (answer C)
are not UFS file systems and cannot be backed up using the
ufsdump
command.
Question 2
Which of the following
tar
commands can be used to back up the
/etc
directory?
❍
A.
tar cvf /dev/rmt/0 /etc
❍
B.
tar cvf /etc /dev/rmt/0
❍
C.
tar +cvf /dev/rmt/0 /etc
❍
D.
tar +cvf /etc/ dev/rmt/0
Answer A is correct. All the other answers do not use proper syntax. In
answer B, the command-line arguments are in the wrong order. The proper
order of command-line arguments is function, followed by the backup
device, followed by the files to back up. The
+c
in answers C and D is incor-
rect (the plus is not a valid argument).

❍
