Question 12
The command
cfsadmin -s xyz
fails. Which of the following is probably the
reason?
❍
A.
xyz
is a mount point; it should be the name of a cache.
❍
B.
The
demandconst
option was not specified when mounting
xyz
.
❍
C.
Cache logging has not been started.
❍
D.
The size of the cache is too small.
Answer B is correct.
xyz
must be a point mount, not a cache name.

-s
command-line argument performs
a consistency check. It does not have anything to do with logging or cache
size. Therefore answers C and D are incorrect.
