Module $9$ A

Analyze the key differences between the Byzantine General Problem $($BGP$)$ and two$-$phase commit protocol. How do these protocols address the challenges of achieving consensus in distributed systems?

Compare and contrast the various commit protocols discussed in Chapter $9.$ What are the fundamental differences between two$-$phase and three$-$phase commit protocols in terms of performance and fault tolerance?

Examine the impact of network latency and node failure on consensus algorithms like BGP and Paxos. How do these factors influence the performance and reliability of these protocols in real$-$world distributed systems?

Module $9$ B

Evaluate the effectiveness of the Byzantine General Problem in environments with highly unreliable nodes. What improvements could be made to enhance fault tolerance in such conditions?

Critique the use of two$-$phase commit protocol in large$-$scale distributed systems. What are the key challenges related to scalability and reliability, and what modifications could be proposed to overcome these limitations$?$

Assess the applicability of three$-$phase commit protocols in modern distributed systems, where high availability is crucial. How does the addition of a third phase improve or complicate the protocol's performance?
