DP-300 Implement a secure environment Practice Question
Which TWO actions should you take to secure Azure SQL Database against SQL injection attacks?
⚠ Common exam trap
Candidates often confuse security features like encryption (TDE) or network controls (firewall rules) with application-layer defenses, mistakenly thinking they prevent SQL injection when they only address different threat vectors.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use parameterized queries in application code
Parameterized queries (Option D) and stored procedures with parameters (Option E) are both effective defenses against SQL injection because they separate SQL code from user input. When using parameterized queries, the database engine treats input as data only, never as executable code, which prevents attackers from injecting malicious SQL statements. This is a fundamental secure coding practice recommended by Microsoft for Azure SQL Database.
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 Transparent Data Encryption
Why it's wrong here
Encrypts data at rest, does not prevent injection.
- ✗
Enable auditing for all database operations
Why it's wrong here
Auditing detects attacks, but does not prevent them.
- ✗
Configure firewall rules to allow only trusted IP addresses
Why it's wrong here
Network security does not prevent injection.
- ✓
Use parameterized queries in application code
Why this is correct
Prevents SQL injection by separating code from data.
- ✓
Use stored procedures with parameters
Why this is correct
Stored procedures with parameters are safe from injection.
