   A company is developing a new airbag control unit. They have a tight deadline and need to test the algorithm under many crash scenarios. They have a limited budget for hardware. Which testing strategy would be most effective?

   • AUse only MiL testing and skip all other levels
   • BSkip MiL and go directly to HiL testing to save time
   • CUse only vehicle-level crash testing
   • DPerform extensive MiL testing to validate the algorithm, then use HiL for a subset of critical scenarios

   What is the primary purpose of Model in the Loop (MiL) testing in automotive software development?

   • ATo validate the behavior of an executable model of the system under test in a simulated environment
   • BTo check the mechanical durability of the vehicle components under extreme conditions
   • CTo verify the final production software on the target microcontroller
   • DTo test the interaction between the electronic control unit (ECU) and real sensors and actuators

   A test engineer is evaluating a MiL test for an autonomous emergency braking (AEB) model. The model correctly triggers braking in most scenarios, but fails to trigger in a specific edge case. The test case is correctly defined. What is the most appropriate next step?

   • AAssume the model is correct and the edge case is unrealistic
   • BIncrease the simulation time step to see if the model triggers later
   • CModify the test case to make it less severe
   • DAnalyze the model's decision logic and the sensor inputs in that edge case

   What is a limitation of Model in the Loop (MiL) testing?

   • AIt cannot test the model's behavior under normal operating conditions
   • BIt does not account for hardware-specific effects such as timing and signal delays
   • CIt can only be used for testing the final production code
   • DIt requires a physical prototype of the vehicle to be built
