Full question →mediummultiple choiceObjective-mapped
A company is deploying a web application on Azure App Service. They need to guarantee that all traffic from the internet goes through a Web Application Firewall (WAF) before reaching the app. The solution must be cost-effective for a single application. Which Azure service should they place in front of the App Service?
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
Azure Application Gateway with WAF.
Application Gateway is a regional Layer 7 load balancer that integrates WAF. It can be placed directly in front of App Service to inspect all incoming traffic. This is a cost-effective solution for a single-region application.
B
Distractor review
Azure Front Door with WAF policy.
Azure Front Door is a global load balancer and application delivery network. It includes WAF, but it is designed for multi-region deployments and can be more expensive for a single-region application. Application Gateway is more appropriate here.
C
Distractor review
Azure Firewall with application rules.
Azure Firewall is a stateful firewall that can filter traffic based on FQDN (application rules), but it does not include a Web Application Firewall (WAF) to protect against OWASP top 10 vulnerabilities. It is not a substitute for a WAF.
D
Distractor review
Azure Traffic Manager.
Azure Traffic Manager is a DNS-based traffic load balancer. It does not have WAF capabilities and cannot inspect HTTP traffic. It simply routes DNS requests to different endpoints.
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 AZ-305 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Azure Application Gateway with WAF. — Azure Application Gateway is a regional web traffic load balancer with built-in WAF capability. It is ideal for a single application in one region, providing Layer 7 routing, SSL termination, and WAF at a lower cost than a global solution. Azure Front Door is a global load balancer with WAF, but it is designed for multi-region deployments and comes with additional costs. Azure Firewall does not provide WAF features; it is a stateful firewall. Traffic Manager is a DNS-level load balancer without WAF.
