Selected Answer: D
-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.

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.

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.

Incorrect. Correct answer is E. From the man page. -a, --all Mount all filesystems (of the given types) mentioned in fstab.

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.
