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.
A company uses Azure Data Lake Storage Gen2 as the data lake. The data engineering team needs to ensure that sensitive data such as credit card numbers are masked when queried by non-admin users. The solution must be implemented within the data lake without moving data to another store. Which TWO features should they use? (Choose two.)
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 Synapse Serverless SQL with dynamic data masking
Option C is correct because Azure Synapse Serverless SQL can query data directly from Azure Data Lake Storage Gen2 and supports dynamic data masking (DDM) to obfuscate sensitive columns like credit card numbers from non-admin users. This allows masking to be applied at query time without moving or transforming the underlying data in the lake.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse dynamic data masking in Azure SQL Database (which requires data to be in a relational store) with the ability to mask data in place in the data lake using Azure Synapse Serverless SQL, and they may overlook Microsoft Purview's role in classifying and labeling sensitive data as a prerequisite for applying masking policies.
Detailed technical explanation
How to think about this question
Azure Synapse Serverless SQL uses an external data source pointing to the data lake and applies DDM via the CREATE MASKING FUNCTION statement on views or external tables. The masking is enforced at the SQL query layer, meaning the underlying Parquet/CSV files remain unchanged, and non-admin users see masked values only when querying through Synapse Serverless SQL. This approach avoids data duplication and leverages the lake's native storage format.
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.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
