   What is the primary benefit of using a cloud device lab for hardware fragmentation management?

   • AIt eliminates the need for any testing
   • BIt guarantees that all hardware issues are found
   • CIt provides access to a wide range of real devices without purchasing them
   • DIt replaces the need for emulators entirely

   A team is testing a fitness app that uses the heart-rate sensor (PPG) and the barometer for altitude tracking. They have a cloud device lab with 100 real devices and a local emulator setup. The app's UI logic is stable, but the sensor data processing is complex. The team must decide how to allocate test effort to maximize defect detection within a fixed time box. Which allocation is most effective?

   • ARun all tests on emulators because they are faster and can simulate sensor data
   • BRun all sensor tests on the cloud device lab and use emulators only for UI regression
   • CRun all tests on the cloud device lab and skip emulators entirely
   • DUse emulators for sensor tests and cloud devices only for UI tests

   A mobile game renders 3D graphics. The team needs to verify the game runs correctly on devices with different GPU capabilities. Which test approach provides the most reliable evidence of GPU-specific rendering defects?

   • ATest on a small set of real devices with GPUs from different vendors (e.g., Adreno, Mali, Apple)
   • BCompare screenshots from two emulators with different API levels
   • CRun the game on an emulator with host GPU passthrough
   • DUse a software renderer on a high-end device to simulate a low-end GPU

   A fitness app uses the accelerometer to count steps and the GPS to map running routes. The target market includes a mid-range device with an older GPS chipset that has lower sensitivity in urban areas. Which test should the team prioritize to address the highest compatibility risk?

   • AVerify the step counter accuracy while the device is in airplane mode
   • BRun the same route test on an emulator with a simulated GPS location
   • CCompare battery drain between the mid-range device and a flagship device during a 30-minute run
   • DTest route mapping accuracy in a dense downtown area on the specific mid-range device
