In some scenarios it is very helpful to use advanced Linux commands for troubleshooting purposes. Which command displays information about resource utilization for running processes and shows addition

Question

Options

• Atop
• Bvmstat
• Ccptop
• Dmpstat

• A
  89% (51)
• B
  5% (3)
• C
  4% (2)
• D
  2% (1)

Explanation

top is correct because it provides a dynamic, real-time view of running processes alongside system-wide resource data - including per-core CPU utilization (toggled with the 1 key) and memory usage - all in a single interactive interface, making it the most comprehensive tool among the choices for this use case.

Why the distractors are wrong:

• B. vmstat reports virtual memory statistics (paging, I/O, CPU) at the system level, but does not display per-process information or interactive per-core breakdown.
• C. cptop is not a real Linux command - it's a fabricated distractor.
• D. mpstat (from the sysstat package) reports per-processor statistics but focuses solely on CPU and does not display individual running processes.

Memory tip: Think of top as the "Total Overview of Processes" - it's the one-stop shop. If an exam question asks for a command that shows both processes and system resources (CPU cores, memory) together, top is almost always the answer.
