Question 4
What does the command
savecore /var/save
do?
❍
A.
Copies the crash dump from
/var/save
to the default
savecore
directo-
ry.
❍
B.
Copies the crash dump from
/var/save
to the
dumpadm
-specified
savecore
directory.
❍
C.
Copies the crash dump from the dump device to the
/var/save
directo-
ry.
❍
D.
Copies the crash dump from the
savecore
directory to the
/var/save
directory.
Answer C is correct. The
savecore
command-line argument is used to spec-
ify an alternative directory from saving a crash dump instead of using the
default or
dumpadm
-specified directory. Therefore, answers A and B are incor-
rect. The
savecore
command copies the crash dump from the dump device,
not the
savecore
device. Therefore answer D is incorrect.
Question 5
Which of the following is the correct syntax for the
mkfile
command?
❍
A.
mkfile -s 32m /swapfile
❍
B.
mkfile 32 M swapfile
❍
C.
mkfile 32m /swapfile
❍
D.
mkfile 32m -f /swapfile
Answer C is correct. The
mkfile
does not use command-line arguments such
as
-s
or
-f
. Therefore answers A and D are incorrect. The size scale (
m
or
M
)
should not be separated from the size; therefore, answer B is incorrect.

all that apply.]
❑

❑
B.
