DP-300 Implement a secure environment Practice Question
You need to protect Azure SQL Database from SQL injection attacks. Which THREE of the following measures should you implement?
⚠ Common exam trap
Test-takers frequently confuse data protection features like dynamic data masking or TDE with SQL injection prevention, when in fact they address entirely different threats (data exposure at query time vs. data at rest encryption).
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
✓
Enable Microsoft Defender for SQL to detect and alert on SQL injection.
Microsoft Defender for SQL provides advanced security capabilities, including vulnerability assessment and threat detection. It specifically monitors for anomalous activities that indicate a SQL injection attack, such as unusual login attempts or queries that match known injection patterns, and can alert administrators or trigger automated responses.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable Microsoft Defender for SQL to detect and alert on SQL injection.
Why this is correct
Defender for SQL includes threat detection for SQL injection patterns.
- ✓
Use parameterized queries or stored procedures in the application.
Why this is correct
Parameterized queries prevent malicious SQL from being interpreted as code.
- ✗
Implement dynamic data masking to hide sensitive data from unauthorized users.
Why it's wrong here
Data masking does not prevent injection; it only hides data in results.
- ✓
Use a web application firewall (WAF) in front of the application to filter malicious inputs.
Why this is correct
WAF can block common SQL injection patterns before they reach the database.
- ✗
Enable Transparent Data Encryption (TDE) to encrypt the database at rest.
Why it's wrong here
TDE protects data at rest, not from injection attacks.
