   Which context factor is most likely to require the use of a dynamic test technique that exercises the software in a simulated environment?

   • AThe regulatory requirements mandate a specific static analysis tool.
   • BThe software controls a safety-critical function such as braking.
   • CThe software must be tested before the physical hardware is available.
   • DThe project phase is in early requirements analysis.

   A team is testing an airbag control unit (ACU). The system is ASIL D, and the software is written in C. The team has a HIL system with the actual ECU and sensors. They need to verify the timing of the airbag deployment, which is critical. They also need to ensure the code is free of dangerous control flow issues. Which combination of techniques is most effective?

   • ABack-to-back testing for timing and exploratory testing for control flow
   • BModel-in-the-loop (MIL) testing for timing and MC/DC for control flow
   • CSIL testing for timing and code review for control flow
   • DHIL testing for timing verification and static analysis for control flow

   A startup is developing a connected car application that provides real-time traffic information. The software is not safety-critical, but it must be released quickly to meet a market opportunity. The team has a small number of developers and no formal testing process. Which test technique is most appropriate for this context?

   • AFormal verification of the entire application
   • BFull MC/DC coverage testing
   • CExploratory testing combined with automated smoke tests
   • DBack-to-back testing against a reference model

   A team is testing a vehicle-to-everything (V2X) communication module. The system is ASIL B, and the software is written in C. The team has a test environment that simulates the V2X network. They need to verify the system's behavior under various network conditions, such as packet loss and latency. They also need to ensure the code is free of buffer overflow vulnerabilities. Which combination of techniques is most appropriate?

   • AMIL testing with a simulated network and MC/DC for buffer overflows
   • BHIL testing with a real V2X radio and code review for buffer overflows
   • CBack-to-back testing and exploratory testing for buffer overflows
   • DSimulation-based testing for network conditions and static analysis for buffer overflows
