Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A financial services company needs to build a data pipeline that ingests daily transaction files from multiple sources. The pipeline must perform data quality checks, transform data using complex business logic, and load it into Azure Synapse Analytics. The transformations involve conditional branching (e.g., if a transaction amount exceeds a threshold, apply additional validation). The company wants to minimize coding effort and prefers a visual, configuration-based approach. Which Azure service should they use as the primary orchestration and transformation engine?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Azure Data Factory with Data Flows
Correct. ADF Data Flows allow visual, code-free transformations with conditional logic, and ADF handles orchestration.
B
Distractor review
Azure Databricks with notebooks
Incorrect. Databricks requires writing code (Python, Scala, SQL) and is not a visual, configuration-based approach.
C
Distractor review
Azure Stream Analytics
Incorrect. Stream Analytics is designed for real-time streaming data, not batch ingestion and complex conditional transformations with branching.
D
Distractor review
Azure Logic Apps
Incorrect. Logic Apps is for workflow automation and integration, not for heavy data transformation and loading into a data warehouse.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

Question 1
A data engineer needs to process streaming data from IoT devices and store the results in Azure Data Lake Storage for long-term analytics. The data must be processed in near real-time to detect anomalies and trigger alerts. Which Azure service should the engineer use for stream processing?
Question 2
A data engineer needs to query data stored in CSV files in Azure Data Lake Storage Gen2 using T-SQL in Azure Synapse Analytics, without loading the data into the database. Which feature should they use?
Question 3
A data engineer needs to process raw clickstream data from multiple websites that is stored in Azure Blob Storage as JSON files. The processing must run automatically every hour, transform the data into a structured format for reporting, and handle schema changes in the source data without manual intervention. Which Azure service should be used?
Question 4
A data engineer is designing a data lake architecture in Azure. They plan to first ingest raw data from various sources into a landing zone in Azure Data Lake Storage Gen2. Then they will clean, validate, and deduplicate that data in a second zone. Finally, they will create aggregated, business-ready datasets in a third zone for analysts. This layered approach is known as which architecture?
Question 5
A data engineer needs to transform large datasets stored in Azure Data Lake Storage Gen2 using Python and Apache Spark. They want a serverless compute option that automatically scales and requires no cluster management. Which Azure service should they use?
Question 6
A company collects customer feedback forms. Each form contains always-present fields like CustomerID and SubmissionDate, but also a free-text Comments field and optional fields like Rating or ProductCategory that vary between forms. How should this data be classified?
FAQ
Questions learners often ask
What does this DP-900 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Azure Data Factory with Data Flows — Azure Data Factory (ADF) with mapping data flows provides a visual, configuration-based environment for building complex data transformations, including conditional branching. ADF can orchestrate the entire pipeline, from ingestion to loading into Synapse, without requiring extensive coding. Azure Databricks requires notebooks with code, Stream Analytics is for real-time streaming, and Logic Apps is better for workflow automation, not heavy data transformations.
