Question 570 of 919
DP-300 Implement a secure environment Practice Question
You are configuring security for an Azure SQL Database that will be used by a web application. The application uses a connection string with SQL authentication. You need to protect the database from SQL injection attacks. Which two measures should you implement? (Choose two.)
⚠ Common exam trap
Test-takers frequently confuse data-at-rest or data-masking features (TDE, DDM, Always Encrypted) with injection prevention, when in fact only query-level controls like parameterized queries and validated stored procedures directly mitigate SQL injection.
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
✓
Use parameterized queries in the application.
Parameterized queries ensure that user input is treated as data, not executable code, by separating SQL logic from input values. This prevents attackers from injecting malicious SQL statements into the query string, which is the primary defense against SQL injection attacks.
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 (TDE).
Why it's wrong here
TDE protects data at rest, not injection.
- ✓
Use parameterized queries in the application.
Why this is correct
Parameterized queries prevent injection.
- ✗
Configure Dynamic Data Masking (DDM).
Why it's wrong here
DDM masks data, but does not prevent injection.
- ✓
Implement stored procedures with input validation.
Why this is correct
Stored procedures can validate inputs.
- ✗
Enable Always Encrypted on sensitive columns.
Why it's wrong here
Always Encrypted does not prevent SQL injection.
