The answer is Azure Stream Analytics and Azure Synapse Analytics. Stream Analytics is purpose-built for real-time data processing on streaming data, offering a SQL-based engine that can analyze high-velocity data from sources like Event Hubs and IoT Hub with sub-second latency. Azure Synapse Analytics, specifically its dedicated SQL pool, supports near-real-time processing by ingesting streaming data via PolyBase or the COPY INTO command into staging tables, then enabling real-time analytics through materialized views and incremental statistics. On the DP-203 exam, this question tests your ability to distinguish between dedicated streaming engines and hybrid batch-streaming platforms; a common trap is selecting only Stream Analytics and overlooking Synapse’s role in combining batch and streaming ingestion patterns. Remember the mnemonic “Stream for speed, Synapse for scale” — Stream Analytics handles the live pipeline, while Synapse provides the analytical horsepower for high-velocity data at rest.
DP-203 Develop data processing Practice Question
This DP-203 practice question tests your understanding of develop data processing. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO Azure services can be used to perform real-time data processing on streaming data?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Synapse Analytics (dedicated SQL pool)
Azure Synapse Analytics (dedicated SQL pool) can ingest and process streaming data using PolyBase or the COPY INTO command to load data from Azure Stream Analytics or Event Hubs into staging tables, then perform real-time analytics via materialized views or incremental statistics. This enables near-real-time processing on high-velocity data by combining batch and streaming ingestion patterns.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Azure Data Factory
Why it's wrong here
ADF is for batch and orchestration, not real-time.
✗
Azure Logic Apps
Why it's wrong here
Logic Apps are for workflows, not stream processing.
✗
Azure Databricks
Why it's wrong here
Databricks is not listed; but Spark can process streams, but the question asks for Azure services.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Data Factory or Logic Apps as real-time streaming services because they can handle event-driven triggers, but they lack the continuous, low-latency query engine required for true stream processing, unlike Stream Analytics and Synapse's dedicated SQL pool with streaming ingestion.
Detailed technical explanation
How to think about this question
Azure Stream Analytics uses a SQL-like query language with temporal windows (tumbling, hopping, sliding, session) to process streaming data from Event Hubs or IoT Hub, outputting to Synapse, Power BI, or storage. Under the hood, it leverages a distributed engine that partitions the stream across nodes for parallel processing, ensuring exactly-once semantics via checkpointing and watermarking. In a real-world scenario, a financial trading platform might use Stream Analytics to detect fraud patterns in milliseconds, then load aggregated results into a Synapse dedicated SQL pool for historical comparison and reporting.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
