Linux Essentials (010-160) — Question 29

Which of the following values could be a process ID on Linux?

Answer options

• A. /bin/bash
• B. 60b503cd-019e-4300-a7be-922f074ef5ce
• C. /sys/pid/9a14
• D. fff3
• E. 21398

Correct answer: E

Explanation

The correct answer is E, as process IDs on Linux are typically positive integers that uniquely identify a running process. Options A, B, C, and D do not represent valid process IDs; A is a path to a shell, B is a UUID, C is a non-standard path, and D is an invalid hexadecimal representation.
