CompTIA Linux+ (XK0-004) — Question 66

A user has connected a Bluetooth mouse to a computer, but it is not working properly. Which of the following commands should the systems administrator use to fix the issue?

Answer options

• A. lsmod ג€"i bluetooth
• B. insmod bluetooth
• C. modprobe ג€"r bluetooth
• D. depmod ג€"i bluetooth

Correct answer: A

Explanation

The correct command is lsmod -i bluetooth, which lists the loaded modules and their status, helping to identify if the Bluetooth module is active. The other options either attempt to insert or remove modules without checking their current status, which may not directly address the issue at hand.
