Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
SIGTERM: Terminates process with cleanup
Common Linux signals include SIGTERM (graceful termination), SIGKILL (force kill), and SIGINT (interrupt via Ctrl+C). Confusions often arise between SIGTERM and SIGKILL, and between SIGINT and SIGKILL.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
SIGTERM: Terminates process with cleanup
Why this is correct
SIGTERM is the default signal sent to terminate a process; it allows the process to perform cleanup before exiting.
SIGKILL: Terminates process immediately
Why this is correct
SIGKILL immediately terminates a process without any cleanup; it cannot be caught or ignored.
SIGINT: Interrupts process (Ctrl+C)
Why this is correct
SIGINT is sent when the user presses Ctrl+C; it typically interrupts the process and prompts termination.
SIGTERM: Immediately terminates process without cleanup
Why it's wrong here
This describes SIGKILL, not SIGTERM. SIGTERM allows cleanup, while SIGKILL does not.
SIGKILL: Interrupts process (Ctrl+C)
Why it's wrong here
This describes SIGINT, not SIGKILL. SIGKILL terminates immediately; SIGINT interrupts gracefully.
