   A test team is testing a new implantable neurostimulator. The device has very limited memory and no external interface. The team needs to verify the device's behavior under various neurological conditions. The team has access to a simulator, an emulator, and a HIL setup. Which environment is most appropriate for testing the device's response to rare but critical neurological events?

   • AA clinical trial with patients who have the condition
   • BA pure software simulator running on a PC
   • CA hardware-in-the-loop (HIL) setup with the actual device and a simulated neurological environment
   • DAn instruction-set simulator (ISS) with a model of the neurological environment

   In a hardware/software system, why is it important to consider real-time behavior when designing the test strategy?

   • AReal-time behavior only affects the user interface, so it is not a primary concern for testing.
   • BReal-time behavior can cause timing-dependent defects that only appear under specific load or timing conditions.
   • CReal-time behavior is irrelevant because all hardware/software systems are asynchronous.
   • DReal-time behavior is only a concern for safety-critical systems, so it can be ignored for other systems.

   In risk-based test prioritization for an embedded system, which factor should be considered when determining the priority of a test?

   • AThe cost of the test equipment.
   • BThe personal preference of the test manager.
   • CThe likelihood of failure and the impact of that failure.
   • DThe number of test cases that can be executed in a day.
