Question

A system has 4 redundant units of a resource. There are 3 processes, each requiring 2 units of the resource. Which of the following is TRUE?

• A. Deadlock is certain to occur.
• B. Deadlock can never occur.
• C. Deadlock occurs only if all processes request resources at the same time.
• D. The system is in an unsafe state.

Hint:

To ensure a system is deadlock-free, the number of resources $R$ must be strictly greater than the sum of (Max Demand - 1) for all processes. Mathematically: $R > \sum (M_i - 1)$.

Answer 1

The Correct Option is B
