Which of the following does a real time kernel NOT provide?

  • A.timers and timeouts derived from its own periodic tick
  • B.a guarantee that the application will meet its deadlines
  • C.a bounded time for each of its own operations
  • D.a means of switching between tasks on priority

Answer: B

The kernel provides the mechanisms; whether the deadlines are met depends on the tasks' execution times and priorities, which are the designer's business. A kernel makes a schedulability analysis possible, and does not perform one.
