AZ-305 · Question 35 · Domain 3.2: High Availability
You are designing a global e-commerce application. The web tier is hosted on Azure App Service in three regions: East US, West Europe, and Southeast Asia.
The application requires:
- Global load balancing to route users to the closest region.
- SSL offloading and Web Application Firewall (WAF) protection at the edge.
- Caching of static assets (images, CSS) at the edge.
- Protection against massive DDoS attacks.
Which load balancing solution should you recommend?

Which load balancing solution should you recommend?
Answer options:
A.
Azure Traffic Manager
B.
Azure Application Gateway
C.
Azure Front Door
D.
Azure Load Balancer (Standard)
How to approach this question
Match the requirements (Global, Layer 7/HTTP, WAF, Caching) to the correct Azure load balancing service.
Full Answer
C.Azure Front Door✓ Correct
Azure Front Door is the correct choice. It operates at Layer 7 (HTTP/HTTPS) and provides global load balancing using anycast routing. It terminates SSL at the edge, includes a Web Application Firewall (WAF), and acts as a Content Delivery Network (CDN) to cache static assets. Traffic Manager is DNS-based and lacks WAF/caching. Application Gateway is regional.
Common mistakes
Choosing Traffic Manager combined with Application Gateway. While possible, Front Door is the single, optimized service that provides all these features globally.
