FC0-U71 Tech Concepts and Terminology Practice Question
A user complains that their laptop battery drains quickly even when the laptop is idle. A technician suspects that a background process is consuming resources. Which of the following Windows tools should the technician use to identify the process consuming the most CPU or disk resources?
⚠ Common exam trap
The trap here is assuming that any monitoring tool can show process resource usage, when only Task Manager (or Resource Monitor) provides that real-time per-process view.
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
✓
Task Manager
Task Manager is the built-in Windows utility that shows real-time resource usage by process. By sorting on CPU or disk columns, the technician can quickly identify a background process causing high usage and draining the battery. The other tools serve different purposes and do not provide per-process resource monitoring.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Event Viewer
Why it's wrong here
Event Viewer logs system, application, and security events. While it can show errors or warnings, it does not provide real-time CPU or disk usage per process. The technician needs to see which process is actively consuming resources, which Event Viewer cannot do, making it unsuitable for this scenario.
- ✓
Task Manager
Why this is correct
Task Manager displays running processes and their real-time CPU, memory, disk, and network usage. In this scenario, the technician can open Task Manager, sort by CPU or disk, and identify the process draining battery. It is the standard Windows tool for this purpose.
- ✗
Device Manager
Why it's wrong here
Device Manager lists hardware devices and their drivers, allowing you to enable, disable, or update drivers. It does not show real-time CPU or disk usage by process. While useful for hardware troubleshooting, it cannot identify a background process causing high resource consumption, so it is not the right tool here.
- ✗
Disk Management
Why it's wrong here
Disk Management is used to manage disk partitions, volumes, and drive letters. It does not provide information about process resource usage. The issue is a background process consuming CPU or disk, not a disk configuration problem, so Disk Management would not help diagnose the battery drain.
