DP-203 Certification Practice Question #121

Question

You are developing a solution that will stream to Azure Stream Analytics. The solution will have both streaming data and reference data.
Which input type should you use for the reference data?

Accepted Answer

Azure Stream Analytics separates streaming inputs from reference-data inputs. Microsoft Learn explicitly lists Blob storage, ADLS Gen2, and Azure SQL Database as supported reference-data sources, while Event Hubs and IoT Hub are stream inputs. Because the only supported option among the choices is Azure Blob storage, and both the suggested answer and community votes agree, B is the clear answer.
