- A
Escape apostrophes in the input before building the SQL statement.
Why wrong: Manual escaping is fragile and often misses edge cases, encodings, and alternate injection paths.
- B
Use parameterized queries or prepared statements for the search filters.
Parameterized queries separate code from data, so user input is treated as values rather than executable SQL. This allows the search function to remain flexible while dramatically reducing injection risk. Prepared statements are the preferred fix because they address the root cause instead of relying on brittle string handling.
- C
Disable database error messages so attackers cannot see query details.
Why wrong: Hiding errors reduces information leakage but does not stop the injection vulnerability from existing.
- D
Place the application behind a VPN so only internal users can run searches.
Why wrong: Restricting network access lowers exposure, but insiders or compromised accounts could still inject SQL.
SY0-701 Threats, Vulnerabilities, and Mitigations Practice Question
This SY0-701 practice question tests your understanding of threats, vulnerabilities, and mitigations. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 development team wants to allow users to search orders by customer name and date range. Logs show the team currently concatenates the filter values into SQL strings. Which change best reduces SQL injection risk without removing the search feature?
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 the search filters.
Option B is correct because parameterized queries (also known as prepared statements) separate SQL logic from user data by sending the query structure and parameters independently to the database. This ensures that user-supplied filter values are always treated as data, never as executable SQL code, which completely prevents SQL injection even if the input contains malicious characters like apostrophes or SQL keywords.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Escape apostrophes in the input before building the SQL statement.
Why it's wrong here
Manual escaping is fragile and often misses edge cases, encodings, and alternate injection paths.

Why this is correct
Parameterized queries separate code from data, so user input is treated as values rather than executable SQL. This allows the search function to remain flexible while dramatically reducing injection risk. Prepared statements are the preferred fix because they address the root cause instead of relying on brittle string handling.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose input escaping (Option A) because it seems like a direct fix for the apostrophe problem, but they fail to recognize that parameterized queries are the only comprehensive defense that eliminates the entire class of SQL injection vulnerabilities regardless of input format.
Detailed technical explanation
How to think about this question
Under the hood, parameterized queries work by sending the SQL statement with placeholders (e.g., `?` in ODBC/JDBC or `$1` in PostgreSQL) to the database server, which compiles the query plan before any user input is bound. This means the database engine knows the exact structure of the query in advance, and the bound parameters are always treated as literal values, making it impossible for input to alter the SQL syntax. In real-world scenarios, even a single unparameterized dynamic SQL statement in a stored procedure or ORM query can lead to full database compromise, as demonstrated by the 2017 Equifax breach where a vulnerable web application allowed attackers to execute arbitrary SQL commands.
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.
