CompTIA Linux+ (XK0-004) — Question 289

A systems administrator suspects a process with a PID of 2864 is consuming resources at an alarming rate. The administrator uses the command renice -n -
5 -p2864, but it does not solve the issue. Which of the following commands should the administrator execute to correct the issue?

Answer options

• A. nice -n 5 -p 2864
• B. nice -n -5 -p 2864
• C. renice -n 10 -p 2864
• D. renice -n -10 -p 2864

Correct answer: C

Explanation

The correct answer is C, as increasing the niceness value to 10 via renice will lower the priority of the process, allowing it to consume fewer resources. Options A and B do not address the issue because they either do not change the niceness effectively or mistakenly attempt to increase the priority. Option D would further increase the priority negatively, exacerbating the resource consumption problem.
