You are designing a global e-commerce web application hosted in three Azure regions (East US, West Europe, Southeast Asia).
The application serves dynamic HTTP/HTTPS content. You need to design a load balancing solution that routes users to the closest region to minimize latency, provides SSL offloading, and includes a Web Application Firewall (WAF) to protect against SQL injection attacks.
Which service should you recommend?

Answer options:
A.
Azure Traffic Manager
B.
Azure Application Gateway
C.
Azure Front Door
D.
Azure Load Balancer
How to approach this question
Combine 'global' + 'HTTP/HTTPS' + 'WAF'. This points directly to Azure Front Door.
Full Answer
C.Azure Front Door✓ Correct
Azure Front Door
Azure Front Door is a global, Layer 7 (HTTP/HTTPS) load balancer. It uses Microsoft's global edge network to route users to the fastest region. Because it operates at Layer 7, it terminates SSL connections (SSL offloading) and integrates with Azure Web Application Firewall (WAF) to protect against common web exploits like SQL injection.
Common mistakes
Choosing Traffic Manager. While Traffic Manager is global, it is DNS-based (Layer 7 unaware) and cannot inspect traffic for WAF or perform SSL offloading.
