ITPEC IP April 2021 Question 21
ITPEC IP April 2021 — Question 21 of 100
A deadlock occurs when processes wait indefinitely for one another to release locked resources. For example, one process holds resource A while waiting for B, and another holds B while waiting for A. Neither can proceed, so the circular wait persists unless the system intervenes.
Answer (c)
Why not others:
- preventing access to protected information is access control
- blocking a user after repeated authentication failures is account lockout
- exhausting an allocated CPU time slice causes scheduling or preemption, not deadlock
Key rule: Deadlock is a circular resource wait in which every involved process is blocked by another.
