An administrator wants to lower the priority of all processes owned by the user 'backup_user' to reduce their impact on a production server. Which command accomplishes this?

kill -15 backup_user && renice -n 15 -u backup_user

A system has two CPU-bound processes: process X with a nice value of 0 and process Y with a nice value of 19. The administrator needs to ensure process X gets more CPU time. What is the most effective action?

Run `renice -n 10 -p ` to lower Y's priority further.

Run `nice -n -5 ` to raise X's priority.

Run `renice -n 5 -p ` to lower X's priority.

A system administrator needs to start a backup script with the lowest possible scheduling priority so it only uses CPU when nothing else needs it. The administrator is logged in as root. Which command should be used?

nice -n 19 /usr/local/bin/backup.sh

renice -n 19 -p $$ && /usr/local/bin/backup.sh

nice -n -20 /usr/local/bin/backup.sh

A server has a process (PID 1111) with a nice value of 0 and another process (PID 2222) with a nice value of 10. The administrator wants to make the first process (1111) get even more CPU time. The administrator is root. What is the most effective action?

Run `nice -n -5 -p 1111` to increase its priority.

Run `renice -n -5 -p 1111` to increase its priority.

Run `renice -n 15 -p 2222` to lower the other process's priority.

Run `kill -STOP 2222` to stop the competing process.

Part of the Topic 103: GNU and Unix Commands domain, which makes up ~19% of our current practice bank. Linux Professional Institute does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–11 in this domain), expect 1–1 from this objective — we provide 24 practice questions to prepare you well beyond it.
