DP-300 Data exfiltration Practice Question
Which THREE features can help protect Azure SQL Database from data exfiltration?
⚠ Common exam trap
Candidates often overlook Always Encrypted as a data exfiltration prevention feature because it primarily protects data in use, but it also prevents exfiltration of readable data.
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
✓
Microsoft Defender for SQL
Microsoft Defender for SQL detects anomalous activities that may indicate data exfiltration attempts. Azure Policy with deny effect for public network access blocks external connectivity, preventing unauthorized data transfer. Always Encrypted ensures that sensitive data remains encrypted even when accessed by unauthorized users, so if data is exfiltrated, it is unusable without the encryption keys. Together, these three features protect Azure SQL Database from data exfiltration.
