Full question →mediummultiple choiceObjective-mapped
A web team is moving a customer portal behind a new inspection device. They need something that can examine HTTP requests, block malicious patterns like injection attempts, and still allow normal browsing. Which control is most appropriate?
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
IDS, because it alerts on suspicious traffic without affecting application delivery.
An IDS can detect attacks, but it typically does not sit in the request path to block them.
B
Best answer
WAF, because it understands web requests and can block malicious application-layer traffic.
A web application firewall is designed to inspect HTTP and HTTPS traffic and stop common web attacks before they reach the app.
C
Distractor review
DLP, because it can stop sensitive data from being posted to the portal.
DLP focuses on protecting data from unauthorized movement, not inspecting and blocking malicious web requests.
D
Distractor review
NAC, because it verifies whether devices are allowed onto the network.
NAC controls network admission for endpoints, not the content of HTTP requests sent to a web application.
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: WAF, because it understands web requests and can block malicious application-layer traffic. — A WAF is the most appropriate control because it operates at the web application layer and can inspect, allow, or block HTTP traffic based on application-aware rules. That makes it well suited for preventing injection attempts while still permitting normal browser traffic. It is a common control when a team needs stronger protection for a public-facing portal without changing the application itself. Why others are wrong: An IDS can detect suspicious traffic but is usually not the right inline blocker. DLP is about preventing unauthorized data exfiltration, not filtering web attacks. NAC manages who may connect to the network, but it does not evaluate the maliciousness of individual HTTP requests.
