Which of the following values could be a process ID on Linux?
A process ID (PID) on Linux is typically a positive integer. The option '21398' fits this description as it is a numeric value that could realistically be a PID assigned by the Linux kernel to a process.
E is correct, the other answers are nothing like a process ID.
E is the correct answer. Linux has a PID limit known as Process Identification Number or PID. This is a system-wide limit on the total number of processes that any user can start at any given time. It helps control resource usage and prevent malicious activity from overloading the system. The default PID limit for most Linux systems is 32768. This limit can be changed. However, setting the number too high is not recommended as it could cause system instability. Additionally, some applications may require a higher limit to function correctly. To find the system's value, you can look up cat /proc/sys/kernel/pid_max
