Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
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?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
SQL injection, because the input may be altering the database query
A quote causing a database syntax error is a classic sign that user input may be breaking SQL queries.
B
Distractor review
Cross-site scripting, because the page is executing malicious JavaScript in the browser
XSS affects browser-side script execution, not database syntax errors caused by a quoted search term.
C
Distractor review
Server-side request forgery, because the server is making internal network calls
SSRF involves forcing the server to request another resource, which is not shown by a SQL error.
D
Distractor review
Cross-site request forgery, because the user is being tricked into submitting a form
CSRF exploits a victim's authenticated browser, not an input field causing a database error.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this SY0-701 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: SQL injection, because the input may be altering the database query — The correct answer is SQL injection. A single quote often breaks out of a query string and reveals that user-supplied input may be directly concatenated into SQL. The resulting syntax error is a common first clue that the application is vulnerable. In practice, developers should use parameterized queries and input validation to prevent user input from changing the structure of database commands. Why others are wrong: XSS targets the browser by injecting script into web content, so it would not normally produce a database syntax error. SSRF is about the server making unauthorized network requests. CSRF tricks a logged-in user into sending a request, but it does not explain the SQL error from a quoted search value.
