LPIC-2 Exam 201 (Linux Engineer) — Question 48

In which directory tree are files modified when changing kernel parameters using the command sysctl?

Answer options

• A. /sys/kernel/
• B. /proc/kernel/
• C. /proc/sys/
• D. /lib/sys/
• E. /sys/proc/

Correct answer: C

Explanation

The correct answer is C, as kernel parameters are accessed and modified in the /proc/sys directory, which is a virtual filesystem representing kernel parameters. The other options do not represent the correct directory for modifying these parameters; for example, /sys/kernel/ and /proc/kernel/ do not contain the sysctl parameters.
