Question 1

A user reports that their smartphone's touchscreen is not working in some areas, making it difficult to use certain applications. What is the BEST course of action?

Correct Answer: Perform a hardware diagnostic and consider a screen replacement.

Question 2

A user wants to connect their smartphone to a projector to give a presentation. The projector has an HDMI input. What is the BEST solution to connect the smartphone to the projector?

Correct Answer: Use an adapter that connects the smartphone to the HDMI input of the projector.

The optimal solution to connect the smartphone to the projector for a presentation is to use an adapter that connects the smartphone to the HDMI input of the projector, allowing direct video transmission. The other options do not address the objective of the presentation.

Question 3

A user can't get their work email on their smartphone despite having a stable internet connection. What should they verify to fix this issue?

Correct Answer: Ensure the email server settings are properly configured.

The best answer is to ensure the email server settings are properly configured. If the user has a stable internet connection but still can't get their work email on their smartphone, the likely issue is that the email account settings on the phone are incorrect. This could include the incoming and outgoing server settings, port numbers, or authentication settings. Replacing the phone battery, switching the language, or disabling the account would not resolve the issue of being unable to receive work emails on the smartphone.
