   A test manager has a team of 10 testers and must test two systems: a body control module (BCM) and an advanced driver-assistance system (ADAS). The ADAS is considered more critical. How should the manager allocate the testers?

   • AAssign all 10 testers to the ADAS and test the BCM later.
   • BAssign 7 testers to the ADAS and 3 to the BCM.
   • CAssign 3 testers to the ADAS and 7 to the BCM because the BCM has more features.
   • DAssign 5 testers to each system to keep the team balanced.

   A company is developing a new head-up display (HUD) and a new braking system. The HUD has more complex features, but the braking system is safety-critical. The project manager wants to ensure the test extent is appropriate. What should the manager do?

   • ATest the braking system more extensively, even though the HUD has more features.
   • BTest both systems equally to avoid bias.
   • CTest the HUD more extensively because it has more features.
   • DTest the HUD first because it is more visible to customers.

   What is the primary role of safety standards such as ISO 26262 in determining the extent of testing for automotive E/E systems?

   • AThey only apply to software testing, not to system-level testing.
   • BThey are optional guidelines that have no impact on the test extent.
   • CThey provide a generic checklist that applies equally to all systems regardless of criticality.
   • DThey prescribe specific test techniques and coverage criteria that vary according to the safety integrity level of the system.

   In automotive software testing, what is the primary reason that a system with higher criticality (e.g., an airbag control unit) requires a more extensive test effort than a non-critical system (e.g., an infotainment display)?

   • AThe potential consequences of failure are more severe, so a higher level of confidence in correct behavior is needed.
   • BCritical systems are tested more because they are more likely to have defects due to complex electronics.
   • CHigher criticality systems have more lines of code, so they inherently require more test cases.
   • DRegulatory standards always require the same test extent for all systems, so criticality has no influence.

   An automotive supplier is developing an electronic power steering system. The project must comply with ISO 26262. How does this standard influence the extent of testing required?

   • AIt mandates a higher test extent, including more rigorous coverage and documentation.
   • BIt requires the same testing as for any non-safety system.
   • CIt has no influence; testing extent is determined solely by the project budget.
   • DIt only requires testing during the final integration phase.
