Which scenario favours Event Hubs over Service Bus?
- A Ordered transactional order processing with dead-lettering
- B High-volume telemetry ingestion with replay and multiple independent consumers (correct answer)
- C Request/reply messaging
- D Scheduled message delivery
Shortcut: Event Hubs is built for millions of events per second with retention and replay. Service Bus suits lower-volume messaging needing transactions, sessions, and dead-lettering.
