CompTIA Linux+ (XK0-005) — Question 134

A Linux administrator created a new file system. Which of the following files must be updated to ensure the filesystem mounts at boot time?

Answer options

• A. /etc/sysctl
• B. /etc/filesystems
• C. /etc/fstab
• D. /etc/nfsmount.conf

Correct answer: C

Explanation

The correct answer is /etc/fstab, as this file is responsible for defining how disk partitions, file systems, and other storage devices are mounted on boot. The other options, such as /etc/sysctl and /etc/nfsmount.conf, do not serve the purpose of mounting file systems at startup.
