Consider the following statements about priority inversion.

1. It arises from a shared resource   2. Inheritance bounds it   3. It cannot occur under earliest deadline first

  • A.1 and 2 only are correct
  • B.1, 2 and 3 are all correct statements about priority inversion
  • C.2 and 3 only are correct
  • D.1 and 3 only are correct

Answer: A

The first two are correct. Dynamic priorities give no immunity: a task with a near deadline can just as well be blocked by one with a distant deadline holding a lock, and the deadline inheritance protocol is the corresponding remedy.
