CompTIA A+ Core 1 (220-1001) — Question 354

Joe, a user, recently installed a new mouse for his laptop. Joe no longer uses a mouse pad because his office desk has a glass top. Joe notices that when he is at the office, the cursor moves on the screen when he does not move the mouse; however, it works fine when he is traveling. Which of the following is MOST likely cause?

Answer options

• A. The device drivers are outdated
• B. Bluetooth is disabled
• C. The mouse is faulty
• D. The surface is too reflective

Correct answer: D

Explanation

The most probable cause of the cursor movement is the reflective nature of the glass desk surface, which can interfere with the mouse's optical sensor. The other options, while they could potentially cause issues, do not directly relate to the specific problem of cursor movement on a reflective surface.
