DP-203 Develop data processing Practice Question
You are designing a data pipeline to ingest streaming data from IoT devices into Azure Synapse Analytics. The data must be available for querying with minimal latency, but you also need to handle spikes in throughput without data loss. Which service should you use as the ingestion layer?
⚠ Common exam trap
Many exam-takers confuse Azure IoT Hub with Event Hubs, assuming IoT Hub is the default for all IoT streaming, but IoT Hub is designed for device management and lower-throughput telemetry, whereas Event Hubs is the dedicated high-throughput ingestion service for analytics pipelines.
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 Event Hubs
Azure Event Hubs is the correct choice because it is a fully managed, real-time data ingestion service optimized for high-throughput streaming data from millions of IoT devices. It provides at-least-once delivery, supports partitioning for massive scale, and integrates natively with Azure Synapse Analytics via the Synapse Pipeline or Event Hubs Capture to handle throughput spikes without data loss.
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 Data Lake Storage Gen2
Why it's wrong here
Data Lake Storage is a data lake, not a real-time ingestion service.
- ✗
Azure Blob Storage
Why it's wrong here
Blob Storage is not designed for real-time streaming ingestion; it's for batch storage.
- ✗
Azure IoT Hub
Why it's wrong here
IoT Hub is for device connectivity and management, not generic streaming.
- ✓
Azure Event Hubs
Why this is correct
Event Hubs is optimized for high-throughput streaming data ingestion with buffering.
