Resuming a stopped process | LinuC Level 1 101 Exam original practice question

1.01.4Basic

PID 4242 is stopped by SIGSTOP.

Resume execution without terminating it.

Which command is appropriate?

Hint 1: Focus on the requirement

The process is stopped, so send the signal that permits execution to continue without terminating it.

Hint 2: Key terms

Review the short definitions before comparing the process and job-control choices.

SIGCONT: A signal that resumes a process stopped by a stop signal.
SIGSTOP: A stop signal that cannot be caught or ignored by the target process.
Process state: The kernel's current state for a process, such as running or stopped.
Job control: Shell mechanisms that stop, resume, and move process groups between foreground and background.

Exact output and option names can vary slightly by distribution and tool version.

Foundation review

SIGCONT changes a stopped process back toward execution; SIGTERM requests termination instead.

Observe the state after sending the signal and distinguish a resumed process from one that exited.
