CompTIA Linux+ (XK0-004) — Question 278

A Linux administrator updated the graphics drivers using a package manager, but now the server does not boot. Which of the following is the BEST way to get the server back into an operational state?

Answer options

• A. Use a system recovery disk to copy the server data to a new system.
• B. Reboot the server with an older kernel version
• C. Kickstart the server and restore to the last system backup.
• D. Boot a live CD, mount and chroot the boot partition, and run fsck.

Correct answer: C

Explanation

The best option is C, as restoring from the last system backup will revert any changes made by the driver update. Option A is not ideal since it merely copies data without fixing the boot issue, while B may not resolve the underlying problem if the drivers are incompatible. Option D involves more complex steps that may not be necessary if a backup is available.
