Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a failure recovery strategy for a Paxos system where the learner loses communication with the acceptors due to a network partition. How would you ensure the consensus remains intact?

💡 Hint: Think about how fault tolerance mechanisms can be integrated.

Challenge 2 Hard

Evaluate the reliability of a Paxos system when learners occasionally receive outdated information due to communication delays. What mechanisms could ensure consistency despite these delays?

💡 Hint: Consider how the system can verify the freshness of its data.
