An Event Grid subscription must not overwhelm a downstream API limited to 10 requests per second. What is the appropriate design?

1. A Deliver directly and rely on retries
2. ✓ B Deliver into a Service Bus queue and have a rate-limited consumer drain it (correct answer)
3. C Reduce the event TTL
4. D Use more subscriptions

Shortcut: Event Grid has no built-in throttling toward the destination. Buffering into a queue decouples the burst-prone event source from the rate-limited consumer.
