Explanation
{"question_number": 4, "question_summary": "Model-Driven Telemetry periodic subscriptions: what must the architect consider?", "correct_answer": "C", "explanation": "Model-Driven Telemetry (MDT) supports two subscription types. Periodic (cadence-based) subscriptions send a complete snapshot of all subscribed data at every configured interval, regardless of whether the data has changed. This is fundamentally different from on-change subscriptions (option A), which transmit data only when a change is detected. Because periodic updates always include the full dataset, architects must plan for higher and predictable bandwidth consumption compared to on-change mode. Option B is incorrect - if no data exists, some implementations still send empty notifications. Option D is incorrect; periodic updates fire on the configured schedule, not immediately.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
