You have an Azure Stream Analytics job that connects to an Azure IoT hub named Hub1445 as a streaming data source. Hub1445 is configured as shown in the exhibit.

The Stream Analytics job fails to receive any messages from the IoT hub.
What should you do to resolve the issue?

A. Disable the Route1 route.
B. Enable the Route3 route.
C. Disable the Route2 route.
D. Enable the fallback route.

Show Suggested Answer

Suggested Answer: B 🗳️
Events are not getting through as Route3, with an events Endpoint, is not enabled.
Note: Azure IoT Hub is a highly scalable publish-subscribe event ingestor optimized for IoT scenarios.
The default timestamp of events coming from an IoT Hub in Stream Analytics is the timestamp that the event arrived in the IoT Hub, which is
EventEnqueuedUtcTime.
