   A tester is participating in a review of safety requirements for an electric power steering system. The tester notices that a requirement states 'the system shall provide steering assist' but does not specify performance limits under failure conditions. What is the tester's most appropriate contribution?

   • ADefer the review until after the system is implemented to see how it behaves.
   • BRewrite the requirement to include specific implementation details, such as motor torque values.
   • CApprove the requirement as written because it is clear enough for design.
   • DAsk for measurable and testable criteria, such as maximum assist degradation time and minimum assist level during failure.

   When developing a test plan aligned with ISO 26262, what should the tester consider?

   • AThe color of the vehicle interior
   • BThe ASIL of the safety requirements to determine the rigor of testing
   • CThe marketing strategy for the vehicle
   • DThe cost of the test equipment only

   What should a tester do when a safety requirement is changed?

   • AOnly update the requirement document, not the tests
   • BDelete all existing test cases and start over
   • CIgnore the change because the original tests are still valid
   • DUpdate the traceability matrix to identify affected test cases and re-test them

   During integration testing of an autonomous emergency braking system, a tester observes that the system fails to apply braking when a pedestrian dummy is placed directly in front of the vehicle at low speed. The failure is reproducible. What is the tester's first action in handling this safety anomaly?

   • AIgnore the failure because it only occurs with a dummy, not a real pedestrian.
   • BDelete the test case from the test suite to avoid the failure in future runs.
   • CImmediately modify the sensor calibration to improve pedestrian detection.
   • DDocument the anomaly with a detailed description, steps to reproduce, and the safety impact, then report it to the defect management system.
