Match the protocol with what it does.

1. Priority inheritance   2. Priority ceiling   3. Sporadic server

P. Bounds the load aperiodic work may impose   Q. Raises the holder to the waiter's priority   R. Raises the holder to the resource's assigned priority

  • A.1-P, 2-R, 3-Q
  • B.1-Q, 2-R, 3-P
  • C.1-R, 2-Q, 3-P
  • D.1-Q, 2-P, 3-R

Answer: B

The first two bound blocking on a shared resource and differ in whose priority is borrowed; the third bounds interference from work that arrives unpredictably. All three exist to turn an unbounded quantity into a bounded one so the analysis can proceed.
