Linux Foundation Certified System Administrator (LFCS) — Question 104

In order to display all currently mounted filesystems, which of the following commands could be used? (Choose TWO correct answers.)

Answer options

• A. cat /proc/self/mounts
• B. free
• C. mount
• D. lsmounts
• E. cat /proc/filesystems

Correct answer: A, C

Explanation

The commands 'cat /proc/self/mounts' and 'mount' are valid for displaying currently mounted filesystems. The 'free' command is used for checking memory usage, 'lsmounts' is not a standard command, and 'cat /proc/filesystems' lists supported filesystems rather than currently mounted ones.
