SY0-701 Threats, Vulnerabilities, and Mitigations Practice Question
This SY0-701 practice question tests your understanding of threats, vulnerabilities, and mitigations. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
During testing, a login form returns all user records when the tester enters ' OR '1'='1 in a username field. What is the best fix for this issue?
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 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
The SQL injection attack ' OR '1'='1 bypasses authentication by always evaluating to true, returning all user records. Parameterized queries (prepared statements) separate SQL logic from user input, preventing the injected string from altering the query structure. This is the industry-standard mitigation for SQL injection vulnerabilities.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Hide database error messages from the login page only
Why it's wrong here
Suppressing errors may reduce information leakage, but it does not stop the injection flaw itself.
✓
Use parameterized queries or prepared statements
Why this is correct
Parameterized queries separate user input from SQL commands, which prevents the database from treating input as executable code.
Clue confirmation
The clue word "best" in the question point toward this answer.

Read the scenario before looking for a memorised answer.
✗
Require users to change passwords more often
Why it's wrong here
Password changes do not address the underlying input validation and query construction problem.
✗
Move the login page to a different URL
Why it's wrong here
Changing the page location does not fix the vulnerable query logic behind the form.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose hiding error messages (Option A) because they confuse symptom masking with root-cause remediation, but the exam tests the principle that input validation and parameterized queries are the only reliable fix for SQL injection.
Detailed technical explanation
How to think about this question
Parameterized queries work by sending the SQL statement and the user input as separate parameters to the database, so the database engine treats the input strictly as data, not executable code. For example, in Java with JDBC, using PreparedStatement.setString() ensures the input is escaped automatically, while in PHP, PDO prepared statements bind parameters safely. Even if the input contains single quotes or SQL keywords, they are never interpreted as part of the SQL command.
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 security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
