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

A team uses Event Grid to notify downstream services when AI model inference results are ready. Which architectural pattern does this implement?

  1. A Request-response (synchronous)
  2. B Event-driven microservices (async notification) (correct answer)
  3. C Batch processing
  4. D CQRS write side only

Shortcut: Publishing an event when results are ready decouples the inference service from consumers. Multiple downstream services can subscribe independently, implementing event-driven microservices architecture.
