System Management

Question

A systems administrator notices a large number of autoloaded device modules are no longer needed and decides to do a cleanup of them. Which of the following commands will accomplish this task?

Options

Armmod -c
Bdepmod -r
Cinsmod -c
Dmodprobe -r

Explanation

The systems administrator wants to remove unused kernel modules that were autoloaded but are no longer necessary.

Common mistakes.

A. rmmod is used to remove a single module, but the -c option is not a standard or recognized flag for this command.
B. depmod is used to generate or verify kernel module dependency information, which is used by modprobe and insmod, not to remove modules. The -r option for depmod is typically used to rebuild module dependency files.
C. insmod is used to insert a single module into the Linux kernel, which is the opposite of removing modules. The -c option is not a standard or recognized flag for insmod.
