A news app is reported to drain battery quickly on older devices. The team suspects background refresh and location services are the cause. Which resource-related testing approach would best confirm this?

Check the app's memory usage to see if it is leaking memory over time.

Run a network test to see how much data the app downloads during background refresh.

Use a battery profiling tool to measure the app's energy consumption over time, with and without background refresh and location services enabled.

Test the app on a device with a fully charged battery and see how long it takes to drain to 50%.

Which of the following is an example of an interruption that should be tested for a mobile app?

An incoming phone call during app usage

A change in the app's color scheme

A change in the device's screen brightness

A VoIP app must handle multiple interruptions: an incoming call, a low-battery warning, and a network switch from Wi-Fi to cellular. The team wants to verify that the app maintains the call and recovers properly after each interruption. Which test sequence is most effective?

Simulate all three interruptions simultaneously to stress the app's handling of concurrent events.

Test only the network switch because it is the most likely to cause call drops.

Simulate the interruptions in a realistic sequence: low-battery warning, then incoming call, then network switch, and verify the call continues and recovers after each.

Test each interruption separately to isolate the app's response to each event.

Which of the following is a testing approach for verifying the security of data transmission in a mobile app?

Measuring the app's memory usage

Checking that the app uses HTTPS for network communication

Testing the app on different screen sizes

Verifying that the app's UI is responsive

A travel app shows different content based on the user's location. Testers need to verify that the app correctly updates the displayed city when the user crosses a time zone while the app is in the background. Which context-related testing scenario is most appropriate?

Test the app in airplane mode to see if it shows cached content.

Rotate the device to landscape and verify the layout adjusts correctly.

Change the device's time zone while the app is in the background, then bring it to the foreground and verify the city is updated.

Simulate a location change while the app is in the foreground and verify the city updates immediately.
