The answer is Task Manager, because it is the built-in Windows tool designed to provide a real-time overview of CPU, memory, and disk usage directly from the Processes and Performance tabs. When a customer reports a slow laptop and suspects a memory-hogging program, Task Manager allows you to sort processes by memory consumption instantly, identifying the culprit without needing additional software. On the CompTIA A+ Core 2 220-1202 exam, this question tests your ability to distinguish between diagnostic utilities: Task Manager is for immediate, live resource monitoring, while Resource Monitor offers deeper detail but is launched from within Task Manager, not as a standalone first step. A common trap is choosing Performance Monitor, which is for historical logging, or System Configuration, which manages startup items. Remember the mnemonic “T-Mac” for Task Manager—Time, Memory, and CPU—to recall it as your go-to for real-time usage checks.
220-1202 Windows OS Features and Tools Practice Question
This 220-1202 practice question tests your understanding of windows os features and tools. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A customer reports that their Windows 10 laptop is running slowly and they suspect a program is using too much memory. They ask you to check the system's resource usage. Which built-in Windows tool would you use to view real-time memory, CPU, and disk usage?
Why wrong: Resource Monitor provides detailed per-process resource data but is typically launched from Task Manager, not as a primary tool for a quick check.
B
Task Manager
Task Manager shows real-time CPU, memory, disk, and network usage in the Performance tab, making it the quickest tool for this scenario.
C
Performance Monitor
Why wrong: Performance Monitor is used for advanced logging and historical data collection, not for an immediate real-time view.
D
System Configuration (msconfig)
Why wrong: System Configuration manages startup programs and boot options, not real-time resource monitoring.
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 provides a real-time overview of system performance, including memory, CPU, and disk usage, making it the ideal tool for diagnosing resource bottlenecks. The Resource Monitor offers more detailed data but is accessed from Task Manager, not directly. Performance Monitor and System Configuration are for advanced logging and startup management, respectively.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

Variation 1. A user reports that their Windows 10 laptop is running slowly and frequently shows a 'Low Memory' warning. They have 8 GB of RAM and are not running any unusual applications. Which built-in Windows tool should you use to determine if a specific process is leaking memory?
easy
A.Performance Monitor
✓ B.Task Manager
C.Event Viewer
D.System Configuration (msconfig)
Why B: Task Manager (Option B) is the correct tool because it provides a real-time view of per-process memory usage, including the 'Memory (Active Private Working Set)' column, which can identify a process that is consuming an abnormally increasing amount of RAM over time—indicative of a memory leak. Unlike other tools, Task Manager allows you to quickly sort processes by memory usage and observe growth without needing to configure counters or parse logs.
