An event delivery fails repeatedly. What is Event Grid's default behaviour?
- A It drops the event immediately
- B It retries with exponential backoff for up to 24 hours, then discards unless a dead-letter destination is configured (correct answer)
- C It queues indefinitely
- D It disables the subscription
Shortcut: Event Grid retries on a backoff schedule bounded by the event time-to-live (24 hours by default). Configuring a dead-letter storage container preserves undeliverable events.
