DP-203 Design and implement data storage Practice Question
You are designing a data storage solution for a manufacturing company that collects sensor data from machines. The data is stored in Azure Data Lake Storage Gen2. You need to ensure that the solution can handle large volumes of streaming data (up to 100 MB/s) and provide real-time dashboards. Which TWO services should you include?
⚠ Common exam trap
Microsoft often tests the misconception that Azure Databricks is a real-time dashboard service, but it is primarily a processing engine that requires additional integration for dashboard output, whereas Stream Analytics is purpose-built for direct, low-latency dashboarding.
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 correct because it is a real-time analytics service designed to process high-velocity streaming data (up to 100 MB/s) from sources like Event Hubs and output to dashboards and storage. It provides low-latency, SQL-based querying for real-time dashboards, making it ideal for manufacturing sensor data scenarios.
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 Analysis Services
Why it's wrong here
Analysis Services is for multidimensional models, not real-time streaming.
- ✗
Azure Data Factory
Why it's wrong here
Data Factory is for batch data integration, not real-time streaming.
- ✗
Azure Databricks
Why it's wrong here
Databricks can handle streaming but is overkill for simple real-time dashboards and may introduce latency.
- ✓
Azure Stream Analytics
Why this is correct
Stream Analytics processes streaming data and can output to real-time dashboards.
- ✓
Azure Event Hubs
Why this is correct
Event Hubs can ingest high-throughput streaming data.
