Assess students' ability to analyze and compare scalability, consistency, and fault-tolerance trade-offs among Paxos, Raft, and Byzantine Fault Tolerance protocols under network partitions. Scope includes algorithmic guarantees (safety vs liveness), fault models (crash vs Byzantine), quorum and leader behavior during partitions, performance impacts (latency, throughput, message complexity, cluster size), and practical configuration choices. Tasks: explain protocol behavior in partition scenarios, quantify trade-offs with examples or simple calculations, evaluate which guarantees are preserved or sacrificed, and recommend protocol/design choices for specified system requirements with technical justification.
