   A tester is updating the traceability matrix for a battery management system. A safety requirement was changed to add a new failure mode. What is the tester's primary responsibility regarding traceability?

   • ADelete the old test cases that were linked to the requirement to keep the matrix clean.
   • BIdentify and update or add test cases that cover the new failure mode and link them to the changed requirement.
   • CWait until the end of the project to update the matrix to avoid extra work.
   • DMark the requirement as 'not testable' and remove it from the matrix.

   A tester is working on a system that is already in production. A new safety-related defect is discovered through customer feedback: the infotainment system occasionally reboots while the vehicle is in motion, which could distract the driver. What is the tester's role in the operation phase?

   • AImmediately issue a recall for all vehicles with the infotainment system.
   • BIgnore the defect because the system is already in production and cannot be changed.
   • CDelete the customer feedback to avoid negative publicity.
   • DAnalyze the reported defect, reproduce it in a test environment, and document the findings for the change management process.

   A test engineer is assigned to a project developing a new autonomous valet parking system. The project is in the early concept phase, and the safety manager is conducting the HARA. The engineer has access to field data from a similar system that shows a specific failure mode occurred in 0.1% of parking maneuvers. The safety manager asks the engineer to help determine the ASIL for the function that controls the parking maneuver. What is the tester's most appropriate contribution?

   • AFocus on writing test cases for the parking function and leave ASIL determination to the safety manager.
   • BDecide the ASIL based on the failure rate alone and document it in the test plan.
   • CWait until the system is designed to determine the ASIL based on the implemented safety mechanisms.
   • DProvide the field data and collaborate with the safety team to assess the severity, exposure, and controllability of the hazardous event.
