CompTIA A+ Core 1 (220-1201) — Question 52

A technician is troubleshooting issues occurring on a user's mobile device. Applications and the OS have slow response times, even when performing simple tasks, such as writing an email. Additionally, new applications occasionally fail to launch. Which of the following should the technician do next?

Answer options

• A. Move the device to a room with a colder temperature.
• B. Close unnecessary programs.
• C. Reset to factory default settings.
• D. Check the battery health of the device.

Correct answer: B

Explanation

Closing unnecessary programs can free up system resources and improve performance, making it the best next step. Moving the device to a cooler room may not address the performance issue, while resetting to factory settings is more drastic and could lead to data loss. Checking battery health is important, but it is not the immediate solution for slow performance.
