CompTIA A+ Core 2 (220-1202) — Question 17

An application's performance is degrading over time. The application is slowing, but it never gives an error and does not crash. Which of the following tools should a technician use to start troubleshooting?

Answer options

• A. Reliability history
• B. Computer management
• C. Resource monitor
• D. Disk defragment

Correct answer: C

Explanation

The correct answer is C, Resource monitor, as it provides detailed information about resource usage and can help identify bottlenecks affecting performance. Options A and B focus more on system reliability and general management, which may not directly address performance issues. Option D, Disk defragment, is useful for optimizing disk performance but does not provide real-time resource monitoring.
