   A test manager is creating a test plan for a new airbag control unit that is assigned ASIL D. The project timeline is tight, and the manager must decide how to allocate test effort. Which approach best aligns with ISO 26262?

   • ADefer most testing to the production phase to save time in development.
   • BDistribute testing effort evenly across all functions to ensure balanced coverage.
   • CAllocate the most rigorous testing to the ASIL D functions, including fault injection and extended stress testing.
   • DFocus testing on the functions that are easiest to test to maximize coverage quickly.

   A test manager is developing a test plan for a new electric power steering system. The system has functions with ASIL B and ASIL D. The project timeline is tight, and the manager must allocate test effort efficiently while meeting ISO 26262 requirements. The manager is considering using the same test techniques for all functions to simplify the plan. What is the most appropriate decision?

   • AUse different test techniques and levels of rigor for ASIL B and ASIL D functions, with more rigorous methods for ASIL D.
   • BFocus all testing on ASIL D functions and skip ASIL B testing to save time.
   • CDefer all testing to the vehicle-level validation phase to reduce development time.
   • DUse the same test techniques for all functions to save time and simplify the test plan.

   A tester discovers a safety-related defect in a braking system during integration testing. The defect is reproducible and could lead to a partial loss of braking power. The tester reports the defect, but the development team is unable to reproduce it in their environment. The tester suspects the defect is related to a specific hardware configuration that is only present in the test lab. What should the tester do?

   • AProvide detailed information about the test environment, including hardware configuration, and work with the team to reproduce the defect using the same setup.
   • BModify the test environment to match the development environment and re-run the test.
   • CIgnore the defect and continue with other testing.
   • DClose the defect because the development team cannot reproduce it.
