DP-203 Develop data processing Practice Question
You are designing a data processing solution for a financial services company. The solution must process sensitive customer data and comply with GDPR. The data will be stored in Azure Synapse Analytics. You need to ensure that only authorized users can view specific columns (e.g., credit card numbers). Which security feature should you implement?
⚠ Common exam trap
It's easy for candidates to confuse Dynamic data masking with access control, but masking only hides data from the UI while still allowing underlying access, whereas column-level security actually prevents unauthorized users from reading the column data at all.
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) in Azure Synapse Analytics allows you to restrict access to specific columns in a table, such as credit card numbers, by granting or denying SELECT permissions on those columns. This directly meets the GDPR requirement to limit exposure of sensitive personal data to authorized users only, without affecting access to other columns.
