Question

Which of the following is not included in deadlock prevention schemes?

a) μtual exclusion
b) Request all resources at once
c) Resource ordering
d) Allow preemption

Answer 1

The correct answer is b) Request all resources at once.

Step-by-step explanation:

The correct answer is b) Request all resources at once. Deadlock prevention schemes are strategies used to avoid the occurrence of deadlocks in a computer system. Deadlocks occur when two or more processes are unable to proceed because each is waiting for the other to release a resource. These schemes include mutual exclusion to ensure that a resource is not simultaneously used by multiple processes, resource ordering to prevent circular wait, and allowing preemption to break deadlocks.
