A company runs a global web application on Azure App Service instances deployed in multiple Azure regions. They want to protect the application from common web attacks such as SQL injection and cross-site scripting (XSS) using a centralized set of managed rules that can be automatically updated. They also need to improve performance by terminating traffic at the nearest point of presence (POP) to end users. Which Azure service should they deploy 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

Distractor review

Azure Application Gateway with Web Application Firewall (WAF)

Application Gateway provides WAF and SSL termination, but it is a regional service. It does not provide the global load balancing and performance improvements from the nearest POP that Azure Front Door offers.

B

Best answer

Azure Front Door with Web Application Firewall (WAF)

Correct. Azure Front Door is a global service that provides both WAF protection (with managed rules) and global load balancing with termination at the edge, improving security and performance.

C

Distractor review

Azure Traffic Manager

Traffic Manager is a DNS-based load balancer that does not provide web application firewall capabilities or SSL termination. It only routes traffic at the DNS level.

D

Distractor review

Azure CDN (Content Delivery Network)

Azure CDN provides caching and performance improvements but does not include a managed web application firewall. While it can be used with WAF on origin, it does not have built-in WAF managed rules.

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-500 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 Front Door with Web Application Firewall (WAF) — Azure Front Door is a global, scalable entry point that uses the Microsoft global edge network to provide fast and secure delivery. It integrates with Azure Web Application Firewall (WAF) to provide centralized protection against common web vulnerabilities, including managed rule sets that are automatically updated. Azure Front Door also provides global load balancing and SSL offloading, meeting both the security and performance requirements. Azure Application Gateway with WAF is regional, not global. Azure Traffic Manager only handles DNS-level traffic distribution without application-layer security. Azure CDN provides caching but not WAF capabilities natively (though it can integrate with WAF).
