A. depmod --rebuild
B. update-dependancies
C. depmod -a
D. insmod -dependancies

Answer: C

Explanation:
depmod creates a list of module dependencies, by reading each module under /lib/modules/version and determining what symbols it exports, and what symbols it needs. By default this list is written to modules.dep in the same directory.

dependencies from the kernel.
To Load the module:
modprobe modulename
To unload the module
modprobe -r modulename

Question 7.

A. /sbin/depmod -a
B. /sbin/depmod -p
C. /sbin/depmod -r
D. /sbin/depmod -c

Answer: A
