Question 1
What does the FLP theorem imply about consensus in distributed systems?
- Consensus is always achievable
- Consensus is impossible under certain failure conditions
- Consensus depends solely on network speed
💡 Hint: Recall the conditions that apply to the FLP theorem.
Question 2
True or False: All systems are able to achieve deterministic consensus regardless of failures.
- True
- False
💡 Hint: Think about the implications of crashes and erroneous behaviors.

Challenge Problems
Push your limits with challenges.
Question 1
Design a hypothetical asynchronous distributed system with a single Byzantine process. Explain how consensus can still be reached despite the risks and what methods could be employed.
💡 Hint: Consider scenarios that allow for consistent communication.
Question 2
Critically assess the effectiveness of probabilistic consensus methods in systems affected by Byzantine failures. What are the potential weaknesses?
💡 Hint: Think about the difference between guaranteed and probabilistic results.
