What is the Event Grid event delivery guarantee?
- A Exactly-once delivery
- B At-least-once delivery with retry (correct answer)
- C At-most-once delivery
- D No delivery guarantee
Shortcut: Event Grid provides at-least-once delivery. For each event, it retries delivery using exponential backoff for up to 24 hours (configurable). Events may be delivered more than once; handlers should be idempotent.
