DP-300 Implement a secure environment Practice Question
Which THREE of the following are features that help protect against data exfiltration in Azure SQL Database? (Choose three.)
⚠ Common exam trap
Test-takers frequently confuse Dynamic Data Masking (DDM) with encryption, thinking it prevents data exfiltration, when in fact it only hides data from specific users and does not protect against direct database access or file theft.
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
✓
Always Encrypted
Always Encrypted is correct because it encrypts sensitive data at the client-side, ensuring that the encryption keys are never revealed to the database engine. This prevents even database administrators or attackers with access to the server from reading the plaintext data, directly protecting against data exfiltration.
