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?
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
Distractor review
Escape apostrophes in the input before building the SQL statement.
Manual escaping is fragile and often misses edge cases, encodings, and alternate injection paths.
B
Best answer
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
Distractor review
Disable database error messages so attackers cannot see query details.
Hiding errors reduces information leakage but does not stop the injection vulnerability from existing.
D
Distractor review
Place the application behind a VPN so only internal users can run searches.
Restricting network access lowers exposure, but insiders or compromised accounts could still inject SQL.
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: Use parameterized queries or prepared statements for the search filters. — Parameterized queries or prepared statements are the best fix because they keep user input separate from SQL logic. That prevents injected characters or clauses from changing the intended query structure. This approach preserves the search feature while removing the unsafe string-concatenation pattern that creates SQL injection risk. It is stronger than filtering or hiding errors and is the standard remediation for this flaw. Why others are wrong: Escaping characters by hand is incomplete and frequently broken by encoding or logic mistakes. Disabling database errors can reduce leakage, but the injection vulnerability remains exploitable. Putting the app behind a VPN narrows access, yet it does not fix the code flaw and still leaves trusted users or compromised internal systems able to attack it.
