Question 1

Multiple microservices read from the same Azure Event Hubs event stream independently without affecting each other. What feature makes this possible?

Accepted Answer

Consumer groups

Answer

Each Event Hubs consumer group maintains its own offset, allowing multiple applications to read the full stream independently.

Question 2

A mobile app backend uses Azure Notification Hubs and needs to send a push notification only to users tagged as 'premium'. What should the developer use?

Accepted Answer

Tag expressions in the send request

Answer

Notification Hubs tag expressions let you target specific device registrations by combining tags with AND/OR logic in the send request.

Question 3

An application uses Azure SignalR Service. A client must receive real-time updates pushed from the server without polling. Which programming model should the developer implement on the server?

Accepted Answer

Hub with server-to-client method invocation

Answer

SignalR Hubs allow the server to invoke named methods on connected clients in real time, enabling true server-push communication.

Question 4

A developer wants to automatically archive all Event Hubs events to Azure Blob Storage for offline analytics. Which feature should they enable?

Accepted Answer

Event Hubs Capture

Answer

Event Hubs Capture automatically delivers streaming events to Azure Blob Storage or Data Lake in Avro format at configurable time/size intervals.

Question 5

A cross-platform mobile app sends push notifications via Azure Notification Hubs. To avoid maintaining platform-specific payloads, what should the developer use?

Accepted Answer

Template registrations

Answer

Template registrations let devices define their own payload format so the backend sends a single generic notification that Notification Hubs adapts per platform.
