CompTIA Linux+ (XK0-004) — Question 89

A systems administrator configured a new kernel module, but it stopped working after reboot. Which of the following will allow the systems administrator to check for module problems during server startup?

Answer options

• A. lsmod
• B. modprobe
• C. modinfo
• D. dmesg

Correct answer: C

Explanation

The correct answer is C, modinfo, which provides details about a specific kernel module, including potential error messages. Options A (lsmod) lists currently loaded modules but does not show startup issues, B (modprobe) is used to load modules but does not provide diagnostic information, and D (dmesg) displays system messages but is less focused on module-specific issues compared to modinfo.
