DP-203 Develop data processing Practice Question
Your organization uses Azure Synapse Analytics. You need to design a data transformation pipeline that processes streaming data from Azure Event Hubs, performs aggregations over a 5-minute tumbling window, and loads the results into a dedicated SQL pool table. Which Azure service should you use to implement the streaming transformation?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Stream Analytics
Azure Stream Analytics is the appropriate service for real-time stream processing with windowed aggregations. Option B is wrong because Azure Data Factory is for batch orchestration. Option C is wrong because Spark Structured Streaming is for big data workloads but less integrated with SQL pools. Option D is wrong because Azure Functions is not designed for streaming windowed aggregations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Azure Stream Analytics
Why this is correct
Azure Stream Analytics can ingest from Event Hubs, perform tumbling window aggregations, and output to Synapse SQL pool.
- ✗
Azure Data Factory
Why it's wrong here
Azure Data Factory is used for batch data integration, not real-time streaming.
- ✗
Apache Spark for Azure Synapse
Why it's wrong here
Spark can process streaming data but requires more setup and is not as straightforward for simple windowed aggregations to SQL pools.
- ✗
Azure Functions
Why it's wrong here
Azure Functions is event-driven compute, not designed for stateful stream processing with windowing.
