LFCS Exam - Question 92


What does the command mount -a do?

Show Answer
Correct Answer: D

The command mount -a ensures that all file systems listed with the option auto in /etc/fstab are mounted. This is because the auto option in /etc/fstab indicates that a filesystem should be automatically mounted during boot or when the mount -a command is executed. The command will not attempt to mount any file system with the noauto option, as this option specifically prevents automatic mounting.

This what man page says: -------------- -a, --all Mount all filesystems (of the given types) mentioned in fstab (except for those whose line contains the noauto keyword). The filesystems are mounted following their order in fstab. --------------------------- E is not correct, because if noauto option is mentioned, then it will not mount.

The mount -a command is used to mount all file systems listed in the /etc/fstab file regardless of their options. This includes file systems with the auto and noauto options. The /etc/fstab file is a configuration file that specifies how file systems should be automatically mounted at boot time or when the mount -a command is executed. The mount -a command reads the /etc/fstab file and attempts to mount all file systems listed in it. So, to summarize, executing mount -a will ensure that all file systems listed in the /etc/fstab file are mounted, regardless of their options.

ChatGPT : The command "mount -a" in Linux is used to mount all filesystems listed in the /etc/fstab file. The /etc/fstab file contains information about filesystems that are automatically mounted at system startup.

-a, --all Mount all filesystems (of the given types) mentioned in fstab (except for those whose line contains the noauto keyword). The filesystems are mounted following their order in fstab. The mount command compares filesystem source, target (and fs root for bind mount or btrfs) to detect already mounted filesystems. The kernel table with already mounted filesys... This means for me, answer D is the right one.

The correct answer is D. It ensures that all file systems listed with the option auto in /etc/fstab are mounted. Explanation: /etc/fstab is a configuration file that lists filesystems and their mount options. The auto option in /etc/fstab indicates that a filesystem should be mounted automatically during boot. The mount -a command reads /etc/fstab and attempts to mount all filesystems marked with the auto option. Important Note: mount -a will not mount filesystems listed in /etc/fstab that have the noauto option, as this option specifically prevents automatic mounting.
