Free CompTIA A+ practice test question 5 for A+ 220-901 Hardware Exam


Question 5

You have been called in by a user that complains that nothing happens when he pokes at his iPhone. Your first step is to try to replicate and sure enough the touch screen is unresponsive. Which of the following solutions would you try first? (Choose two.)

Click Start > Device Manager and reset the touch screen driver
If there is a case or screen protector, remove it
Wipe the screen with window cleaner
Restart the device
In classic view, open Control Panel and click Settings

The correct answer is given at the very bottom of the page – this will give you a chance to think about it…

A+ 220-901 Hardware Exam Objectives

Main Domain: 4.0 Hardware and Network Troubleshooting

Sub-Objective: 4.5 – “Given a scenario, troubleshoot and repair common mobile device issues while adhering to the appropriate procedures.”

The “Start” button that takes you to Device Manager is a Windows feature that you won’t be finding on an iPhone. Some screen protectors are just thick enough to interfere with the touch screen interface. If after removing it the touchscreen works, then recommend the user get a screen protector that is licensed for iPhone. Never use potent chemicals such as window cleaner on these screens. Only wipe them with an electronic wipe, or with a soft and lint-free cloth. Just like rebooting a PC, restarting a device can eliminate a lot of dysfunctions in a device. Just like in the first choice opening Control Panel and clicking Settings will work on a Windows laptop (it’s actually Tablet PC Settings) just not on an iPhone.

  1. “If there is a case or screen protector, remove it”

    I get that this is an accepted answer, but I can’t help to point out that screen protectors are designed to not interfere with the display. I know in extreme cases it might, but generally it won’t.

    1. Hi Shay, the case and the screen protector are treated as add-on elements in the test. As such you would remove them and any possible problems they may present.
      We do agree that screen protector problems are rare but they do, on occasion, occur.
