DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
You are designing a security strategy for Azure Synapse Analytics. The solution must prevent users from accessing sensitive columns in a dedicated SQL pool, such as Social Security numbers, unless they have explicit permission. Which feature should you use?
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
✓
Column-level security.
Column-level security (CLS) restricts access to specific columns by granting or denying SELECT permissions on individual columns. Option C (Dynamic data masking) obfuscates data at query time but does not prevent access, as users can still see the data if they bypass masking. Option B (Azure Purview) is a data governance service for cataloging and classifying data, not for access control. Option D (Row-level security) filters rows based on user context, not columns.
