- A
Use parameterized queries or prepared statements for all database access.
Parameterized queries keep user input separate from the SQL command structure, which blocks injection attacks effectively.
- B
Validate and constrain user input before it reaches the database layer.
Input validation reduces dangerous characters and unexpected values, making exploitation harder and improving overall application security.
- C
Store the database password in the page source so the app can connect faster.
Why wrong: Putting credentials in source code exposes secrets to anyone who can view the application files or web content.
- D
Disable TLS so the application can inspect requests more easily.
Why wrong: Disabling TLS weakens transport security and does nothing to prevent SQL injection in the application logic.
- E
Allow the application to build SQL statements by concatenating raw user input.
Why wrong: Concatenating raw input is the classic cause of SQL injection and directly increases the vulnerability.
SY0-701 Threats, Vulnerabilities, and Mitigations Practice Question
This SY0-701 practice question tests your understanding of threats, vulnerabilities, and mitigations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A developer wants to reduce the risk of SQL injection in a new customer search form. Which two changes are the best mitigations? Select two.
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
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 or prepared statements for all database access.
Option A is correct because parameterized queries and prepared statements separate SQL logic from user-supplied data, ensuring that input is treated as a literal value rather than executable code. This prevents attackers from injecting malicious SQL commands into the query string, as the database driver automatically escapes or binds parameters safely. This is the most effective defense against SQL injection attacks.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think input validation alone is sufficient, but the exam emphasizes that parameterized queries are the definitive mitigation, while validation is a secondary defense-in-depth layer.
Detailed technical explanation
How to think about this question
Parameterized queries work by sending the SQL statement template and the parameters separately to the database server, so the server compiles the query structure before any user input is substituted. This means even if an attacker supplies a value like ' OR 1=1 --, it is treated as a string literal, not as SQL code. In contrast, input validation alone can be bypassed if encoding or edge cases are missed, making parameterized queries the primary defense.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
