Assess graduate students' understanding of strong, eventual, and causal consistency in distributed databases: define each model, explain mechanisms used to implement them (e.g., consensus, quorums, vector clocks, anti-entropy), identify typical anomalies and application use cases, and analyze trade-offs among latency, availability, throughput, and staleness. Questions should require justification of model choices for given system requirements and evaluation of mitigation strategies for consistency-related issues.
