Given relation R(A, B, C, D, E) with functional dependencies: F = { A → B, BC → D, E → C, D → A }.
Given public prime and generator, compute Alice's public key A, Bob's public key B, and the negotiated shared symmetric key K.
Solve for hexagonal cluster size N = i^2 + ij + j^2, co-channel reuse ratio Q = √(3N), and capacity per cell.
A cluster ingests a raw dataset of 320 GB. Default HDFS block size is 128 MB, and the replication factor is set to 3.
A cloud service has Mean Time Between Failures (MTBF) = 4,320 hours and Mean Time To Repair (MTTR) = 0.5 hours (30 min failover).
Prepare a complete answer containing architectural sketches, algebraic formulas, algorithms, and trade-off analysis as expected in university end-semester examinations.
Check off each component you have addressed in your answer. University examiners award marks based on these specific technical deliverables:

Click "Run Key Exchange Protocol" to observe the step-by-step modular mathematics.
Calculate cluster sizes N = i² + ij + j², co-channel reuse distance D = R√(3N), and signal-to-interference ratio (SIR).
Click "Calculate Hexagonal Reuse Metrics" to compute cluster geometry and co-channel distance.
Model distributed storage footprint, 3x rack replication overhead, and NameNode heap memory requirement (~150 bytes per block metadata).
Click "Plan Cluster Capacity" to compute disk, block count, and NameNode memory requirements.
Construct a formal 6-part SEI Quality Attribute Scenario and select the architectural tactic to verify if the SLA response measure is satisfied.
