CompTIA Linux+ (XK0-004) — Question 138

A new video card was added to a customer workstation. To get the new video card to work correctly, a systems administrator needs to remove support for the nouveau video driver on the Linux workstation.
Which of the following will accomplish this task?

Answer options

• A. Use rmmod -f nouveau.
• B. Use modprobe -R nouveau.
• C. Add blacklist nouveau to /etc/modprobe.d/blacklist.conf.
• D. Add blacklist nouveau to /etc/modprobe.conf.

Correct answer: A

Explanation

The correct option is A, as using 'rmmod -f nouveau' forcefully removes the nouveau driver from the system, allowing the new video card to function without conflict. Option B is incorrect because 'modprobe -R' is not a valid command for removing a module. Options C and D involve blacklisting the nouveau driver, but they do not immediately remove it from the current session, which is required for immediate effect.
