Which of the following is a resource constraint that can affect mobile app testing?

Limited CPU and memory compared to desktop computers

The need to test on different screen sizes

The need to test on multiple network providers

The need to test for compatibility with different operating systems

A health app stores sensitive patient data on the device and syncs it to a backend server. During security testing, testers discover that the data is stored in plain text in the app's local database. What is the most appropriate action to address this vulnerability?

Move all data to the backend server and remove local storage entirely.

Encrypt the local database and ensure the encryption keys are stored securely.

Use a more complex database schema to obscure the data.

Rely on the device's screen lock to protect the data.

A navigation app is being tested. During a test, an incoming call interrupts the app while it is giving turn-by-turn directions. The testers want to ensure the app resumes correctly after the call ends. Which testing activity is most important to perform?

Ensure the app does not crash when the call comes in.

Check that the app's audio volume is not affected by the call.

Test that the app can be restarted quickly after the call.

Verify that the app resumes navigation and continues to provide accurate directions after the call.

A mobile app for a hospital uses a backend server to store patient records and also integrates with a Bluetooth heart-rate monitor. The team is testing the app in a real hospital environment. Which testing challenge is most likely to be encountered?

Interference from other Bluetooth devices in the hospital.

The app's performance on low-end devices.

The app's compatibility with different versions of the backend API.

The app's inability to handle a large number of users.

A company develops a productivity app that must support both iOS and Android. They have a limited budget and need to test on a variety of devices with different screen sizes and OS versions. Which testing strategy is most cost-effective for covering fragmentation?

Outsource testing to a third-party lab that has a large device inventory.

Use only emulators for all testing to save money.

Test only on the latest devices to ensure future compatibility.

Purchase a few popular devices and use emulators for the rest.
