A Linux systems administrator is running an important maintenance task that consumes a large amount...

Process scheduling and resource management are essential Linux administration skills covered in Linux+ V8. When a process consumes excessive CPU resources, it can negatively impact overall system performance.

The correct solution is to lower the priority of the CPU-intensive task using the renice command. Niceness values influence how much CPU time a process receives relative to others. Increasing the niceness value reduces the process’s priority, allowing other applications to receive CPU resources more fairly.

Option B directly addresses the issue. The other options do not. pidstat monitors processes but does not modify CPU allocation. nohup allows a process to continue running after logout but does not affect scheduling priority. bg resumes a stopped job in the background but does not reduce CPU usage.

Linux+ V8 documentation explicitly references nice and renice for managing CPU contention. Therefore, the correct answer is B.
