   Which of the following is a specific challenge when testing embedded systems?

   • AThe system has no safety-critical requirements, so testing can be less rigorous.
   • BThe system is completely independent of hardware, so testing can be done entirely in a simulated environment.
   • CThe system has unlimited observability, so all internal states are easily accessible.
   • DLimited observability makes it difficult to inspect internal states and diagnose failures.

   A test manager is reporting on the quality of a new embedded system to stakeholders. The system has a high number of defects found during HIL testing, but few defects found during earlier unit testing. The stakeholders are concerned about the quality of the system. What is the best way to report on the quality?

   • AReport the total number of defects found, without breaking it down by test level
   • BReport the code coverage percentage, as it is a standard quality metric
   • CReport only the number of defects found in HIL testing, as it is the most recent
   • DReport the defect detection percentage (DDP) for each test level, showing that HIL testing is effective at finding defects

   Why is coordination between test, development, and hardware teams important in a hardware/software project?

   • ATo reduce the need for documentation.
   • BTo ensure that test environments and hardware prototypes are available when needed.
   • CTo eliminate the need for integration testing.
   • DTo allow testers to work independently without sharing information.

   What is a key consideration when selecting a test tool for an embedded system?

   • AThe tool must be the cheapest option available.
   • BThe tool must be able to test all types of software, regardless of the hardware.
   • CThe tool must be a commercial product, not open-source.
   • DThe tool must support the specific hardware platform and its interfaces.
