Difficulty: EasymacOS and Linux Operating System Features and Tools

A technician needs to inspect active running processes and current system resource usage on a Linux computer via the command line. Which of the following utilities can be used to view active processes? (Select TWO.)

  1. psAnswer
  2. topAnswer
  3. C
    chmod
  4. D
    chown

Answer

The commands 'ps' and 'top' are both native utilities used to inspect active processes on Unix-like operating systems such as Linux and macOS.
The 'ps' command lists currently running processes in a static snapshot format, whereas the 'top' command dynamically updates and displays running processes along with CPU and memory resource consumption.

Step-by-Step Solution

1
Identify command-line tools designed for process administration on Linux and macOS.
Recognize that 'ps' (process status) generates a snapshot listing of current processes, and 'top' provides a dynamic real-time view of running processes.
Both utilities are standard command-line tools explicitly designed for process inspection.
2
Evaluate the remaining choices to rule out non-process tools.
Identify that 'chmod' manages access permission modes and 'chown' modifies file ownership.
Neither file management command monitors system activity or running tasks.
