Question 1

A user experiences slow performance on their mobile device. Which of the following steps should you advise the user to take first?

Correct Answer: Close running background applications.

When a mobile device is experiencing slow performance, the first troubleshooting step should be to close any running background applications. Background apps can consume system resources like RAM and CPU, leading to reduced performance. Closing these apps can free up resources and potentially improve the device's speed. Fully charging the battery, while beneficial, does not directly address performance issues. Connecting to a different Wi-Fi network could help if the issue is related to a slow or unstable connection, but it's not the most effective first step for general performance problems. Replacing the device's storage is a more drastic measure and should only be considered if other solutions fail or if the storage is faulty.

Question 2

An employee's mobile device is frequently running out of battery power. They suspect that an app may be causing the issue. What should be the first action to narrow down the culprit?

Correct Answer: Check the battery usage statistics in the device settings.

The best first step to determine which app might be causing excessive battery drain is to check the battery usage statistics provided in the device settings. These statistics show the power consumption of individual apps, allowing you to identify any apps that are using a disproportionate amount of battery. This is a quick and effective way to narrow down the potential culprit without making unnecessary changes to the device. Updating all installed apps may resolve the issue if it's caused by a bug, but it doesn't directly help identify the problematic app. Disconnecting from Wi-Fi might reduce overall battery usage but doesn't isolate the app causing the drain. Uninstalling and reinstalling apps one by one is a time-consuming troubleshooting step that should be attempted after the problematic app is identified, not as a first step.

Question 3

A mobile device has developed a problem where the screen flickers intermittently. Which action would be the most appropriate to troubleshoot this problem?

Correct Answer: Check for an OS or display driver update.

A screen flickering issue could be caused by outdated OS or display driver software. The best first action is to check for any available updates. The other answers may be useful, but should only be attempted after the initial troubleshooting has been done.
