Full question →mediummultiple choiceObjective-mapped
A public web application is seeing bursts of requests that contain SQL metacharacters, encoded script tags, and attempts to POST to administrative endpoints. The team wants a control that can inspect HTTP traffic and block the malicious requests before they reach the app. What should be deployed?
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
A web application firewall in front of the application
A WAF is designed to inspect HTTP/S traffic and block common web attacks such as SQL injection and cross-site scripting before they reach the application.
B
Distractor review
An endpoint detection and response agent on the web server only
EDR helps detect malicious activity on the host, but it does not provide dedicated inline inspection of web requests at the perimeter.
C
Distractor review
A data loss prevention rule on the email gateway
DLP focuses on protecting sensitive data from leaving the organization and is not built to block hostile web requests.
D
Distractor review
A network access control system for user authentication
NAC controls device access to the network, but it does not inspect application-layer web payloads for injection attempts.
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: A web application firewall in front of the application — A web application firewall is the best fit because it can analyze HTTP and HTTPS traffic at the application layer and block patterns commonly associated with SQL injection, XSS, and malicious administrative requests. It provides a control point before the traffic reaches the web server, which is exactly what the team wants. While other tools may alert or help elsewhere, a WAF is purpose-built for this kind of inline web protection. Why others are wrong: EDR is useful for host-level detection, but it is not a front-line web request filter. DLP is aimed at preventing sensitive data exfiltration, not inspecting hostile payloads. NAC regulates which devices connect to the network, but it does not make decisions about the content of HTTP requests to a public web application.
