An organization publishes events from 50 different IoT tenants, each needing isolated event subscriptions. Which Event Grid concept efficiently manages this multi-tenant scenario?
- A 50 separate custom topics
- B Event Grid Domain (single endpoint, multiple topics within) (correct answer)
- C Event Hub namespace
- D Partner topics
Shortcut: Event Grid Domains provide a single management endpoint with auto-created topics per domain topic name. This enables efficient multi-tenant event publishing without managing hundreds of separate topics.
