220-1102 Operating Systems Practice Question
A technician is supporting a warehouse desktop. The immediate goal is to list Linux processes and owners for review. Which tool, control, or procedure is the best fit?
⚠ Common exam trap
A common mix-up: candidates confuse Windows administrative tools (System Restore, Event Viewer, Local Users and Groups) with Linux commands, as the CompTIA 220-1102 exam tests both operating systems and expects you to know which tools belong to which OS.
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, CPU/memory usage, and other details, making it the correct tool for a technician to review Linux processes and owners. It is a standard Linux command that displays process information in a user-readable format.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
ps aux
Why this is correct
The ps command with the aux options lists every process on the system, including those owned by other users, showing user, PID, CPU and memory usage. This directly satisfies the goal of listing Linux processes alongside their owners for review on the warehouse desktop.
- ✗
System Restore
Why it's wrong here
System Restore reverts Windows registry and system files to a prior restore point; it cannot enumerate Linux processes or their owning users, so it fails this task outright. It is tempting because it is a familiar Windows recovery tool, and it would be the right choice when a Windows desktop breaks after a bad driver or update.
- ✗
Event Viewer
Why it's wrong here
Event Viewer reads Windows event logs from channels such as System and Application; it records logged events, not running Linux processes with their owning users. It is tempting because it is the standard Windows diagnostic console, and it would be correct when investigating Windows errors, warnings or audit entries.
- ✗
Local Users and Groups
Why it's wrong here
Local Users and Groups manages Windows local account and group membership through lusrmgr.msc; it exposes no process list and no Linux ownership data. It is tempting as a Windows account administration console, and it would be correct when creating or modifying local Windows user accounts and group assignments.
