Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a distributed system that uses quorum-based mutual exclusion. Describe how you would set up the quorum for different processes.

💡 Hint: Draw a diagram showing how processes will interact and form quorum sets.

Challenge 2 Hard

Imagine a scenario where processes A, B, and C are waiting for resources held by each other. Illustrate how this could lead to a deadlock and propose a strategy to resolve it.

💡 Hint: Think about how implementing time constraints could help resolve waiting states.
