Assess students' ability to analyze trade-offs among consistency, latency, and availability in geo-distributed replicated databases under network partitions and workload skew. Scope includes CAP/PACELC intuitions, strong vs. weaker consistency models (causal, eventual), leader/multi-leader and quorum-based replication, quorum sizing and placement, effects of network partitions and skewed read/write hotspots on latency and availability, staleness and conflict-resolution costs, and interpreting experimental or simulated metrics. Questions should require evaluating scenarios, recommending configurations, and justifying trade-offs quantitatively and qualitatively.
