LPIC-1 Exam 101 v5 (Linux Administrator) — Question 113

What is the process ID number of the init process on a System V init based system?

Answer options

• A. -1
• B. 0
• C. 1
• D. It is different with each reboot
• E. It is set to the current run level

Correct answer: C

Explanation

The init process has a process ID of 1 on System V init based systems, making option C the correct choice. Option A is incorrect because -1 is not a valid PID, option B is wrong as PID 0 is reserved for the scheduler, and option D is misleading since the PID of init remains consistent across reboots.
