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 support portal searches customer records by last name. When a tester enters a single quote into the search field, the application returns a database syntax error. Which attack is most likely possible?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SQL injection, because the input may be altering the database query
The single quote character is a common SQL injection test payload. When it triggers a database syntax error, it confirms that the input is being directly concatenated into a SQL query without proper sanitization or parameterization. This allows an attacker to break out of the intended query structure and execute arbitrary SQL commands, making SQL injection the most likely attack.
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.
✓
SQL injection, because the input may be altering the database query
Why this is correct
A quote causing a database syntax error is a classic sign that user input may be breaking SQL queries.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Cross-site scripting, because the page is executing malicious JavaScript in the browser
Why it's wrong here
XSS affects browser-side script execution, not database syntax errors caused by a quoted search term.
✗
Server-side request forgery, because the server is making internal network calls
Why it's wrong here
SSRF involves forcing the server to request another resource, which is not shown by a SQL error.
✗
Cross-site request forgery, because the user is being tricked into submitting a form
Why it's wrong here
CSRF exploits a victim's authenticated browser, not an input field causing a database error.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse a database syntax error with a client-side script error, leading them to choose cross-site scripting, but the error message originates from the database server, not the browser.
Trap categories for this question
Command / output trap
SSRF involves forcing the server to request another resource, which is not shown by a SQL error.
Detailed technical explanation
How to think about this question
SQL injection exploits the lack of input validation or parameterized queries (e.g., using prepared statements with bound parameters). A single quote in a query like SELECT * FROM customers WHERE last_name = '$input' would break the string delimiter, causing a syntax error. In a real-world scenario, an attacker could use UNION-based injection to extract data from other tables, such as user credentials, by appending UNION SELECT username, password FROM users.
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.
