CompTIA A+ Core 2 (220-1102) — Question 73

A suite of security applications was installed a few days ago on a user's home computer. The user reports that the computer has been running slowly since the installation. The user notices the hard drive activity light is constantly solid. Which of the following should be checked FIRST?

Answer options

• A. Services in Control Panel to check for overutilization
• B. Performance Monitor to check for resource utilization
• C. System File Checker to check for modified Windows files
• D. Event Viewer to identify errors

Correct answer: B

Explanation

The correct answer is B because Performance Monitor provides detailed insights into resource usage, allowing the user to identify if the new security applications are consuming excessive system resources. The other options may help in troubleshooting but do not directly assess resource utilization as effectively as Performance Monitor does.
