   A supplier is developing a new infotainment system that includes a safety-critical function (e.g., a backup camera) and non-critical functions (e.g., media playback). The project has a limited budget and must meet ISO 26262 requirements for the safety-critical function. Which test level tailoring approach best meets the project's needs?

   • AApply the same test levels to all functions to ensure consistency.
   • BApply full test levels (component, integration, system, acceptance) to the safety-critical function, and reduce testing for non-critical functions based on risk.
   • CPerform only system testing for the safety-critical function.
   • DSkip component testing for all functions to save time.

   A small automotive supplier is developing a non-safety-critical convenience feature, such as a power window control. The project has a tight budget and schedule. According to test level selection and tailoring, what is the most appropriate approach?

   • APerform only acceptance testing with the customer.
   • BSkip all testing because the feature is non-safety-critical.
   • CPerform all test levels (component, integration, system, acceptance) with full rigor regardless of risk.
   • DTailor the test levels based on risk, focusing on system-level testing and reducing component-level testing.

   An automotive software team is developing a new airbag control unit. They need to test the software components early in the development cycle before the physical ECU hardware is available. Which test environment is most appropriate for this early testing?

   • AHardware-in-the-loop (HIL) test bench
   • BVehicle-level test on a test track
   • CAcceptance testing with the customer
   • DSoftware-in-the-loop (SIL) simulation
