220-1102 Operating Systems Practice Question
A technician is supporting a field engineer tablet. The immediate goal is to list Linux processes and owners for review. Which tool, control, or procedure is the best fit?
⚠ Common exam trap
The trap here is that candidates familiar with Windows may confuse 'Event Viewer' or 'System Restore' as cross-platform tools, but the question explicitly targets Linux, where 'ps aux' is the correct command for listing processes and owners.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
ps aux
The 'ps aux' command lists all running processes with their owners, which directly meets the goal of reviewing Linux processes and owners. It is the standard tool for process monitoring in Linux, displaying user, PID, CPU/memory usage, and command details.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
System Restore
Why it's wrong here
System Restore creates and applies restore points that roll back Windows system files, registry settings, and drivers to a previous state. While it can undo a problematic update or install, it cannot enumerate the currently running processes on a field engineer's tablet. Choosing it would waste time and potentially revert the device state, making the immediate operational need worse.
- ✓
ps aux
Why this is correct
The ps aux command lists every running process on a Linux/Unix tablet, displaying its user, PID, CPU and memory usage, start time, and full command line. It directly satisfies the immediate goal of enumerating what is currently executing, which is essential for spotting rogue or hung applications. This real-time snapshot is the practical first step in field troubleshooting.
- ✗
Local Users and Groups
Why it's wrong here
Local Users and Groups is a Windows Computer Management snap-in for creating and modifying user accounts and group memberships, not for process enumeration. If the tablet runs a Unix-like OS, this tool may not even exist; on Windows, it addresses authorization issues rather than showing running programs. The field engineer's immediate need is not identity management but a process list.
- ✗
Event Viewer
Why it's wrong here
Event Viewer centralizes Windows event logs for system, security, and application messages, serving after-the-fact analysis of errors and warnings. It does not query the live process table, so it cannot show the field engineer what is currently executing on the tablet. Investigating logs before having a process list would sidestep the stated task and postpone the needed action.
