Q27 Event Grid Domain 3 · 20–25% of exam Priority · Real Exam

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.
