A designer moves work out of an interrupt handler into a task in order to

  • A.remove it from the schedulability analysis altogether
  • B.bring it under the control of the priority scheme
  • C.reduce the total processor time the work consumes
  • D.avoid having to measure its execution time

Answer: B

Inside a handler the work outranks every task regardless of its importance; as a task it takes its proper place in the priority order and can be preempted by more urgent work. The total time consumed is much the same, and it still has to be analysed.
