CompTIA Linux+ (XK0-004) — Question 210

A systems engineer scheduled an at job that will reboot a critical server. A developer states the processes will not complete for another three hours.
Which of the following will help the systems engineer to remove the job?

Answer options

• A. atq atrm <at job number>
• B. at -q atrm <PID>
• C. atq atrm <PID>
• D. at -q atrm <at job number>

Correct answer: A

Explanation

The correct command is 'atq atrm <at job number>', which allows the systems engineer to remove the scheduled job by specifying its job number. The other options are incorrect as they either misuse the syntax or reference the wrong identifiers, such as PID instead of the job number.
