   A team is testing a video conferencing app that must work on both Wi-Fi and cellular networks. The app has a feature that automatically switches between front and rear cameras. During a test, the app crashes when the network switches from Wi-Fi to 4G while the camera is being used. What is the most likely cause?

   • AThe app's video encoding is too heavy for the device's CPU.
   • BThe app's user interface is not optimized for the device's screen size.
   • CThe app is not compatible with the device's camera hardware.
   • DThe app does not handle the network change gracefully, causing a race condition with the camera.

   A mobile team is testing a fitness app that uses a heart-rate monitor and a step counter. The app must support a wide range of Android devices, from low-end phones with 2 GB RAM to high-end flagships. The team has limited test devices and needs to maximize coverage of performance-related issues. Which approach best addresses the fragmentation challenge while staying within the device budget?

   • ATest only on emulators with different screen sizes to cover fragmentation, as they accurately simulate hardware performance.
   • BTest on a few high-end devices and rely on the app's responsive design to handle lower-end hardware.
   • CUse a cloud-based device farm to test on a representative sample of low-end and high-end devices, focusing on performance and usability.
   • DPrioritize testing on the most popular device model to ensure the majority of users are covered.
