Show answer & explanationAnswer & explanation
Correct answer: D. Azure Front Door
Azure Front Door is a global, scalable entry point that uses Microsoft's global edge network to create fast, secure, and widely scalable web applications. It provides dynamic site acceleration and global HTTP(S) load balancing with geographic routing capabilities.
Why the other options are wrong
- A. Azure Application Gateway is a Layer 7 (application layer) load balancer within a single region, often including WAF.
- B. Azure VPN Gateway is used for connecting on-premises networks to Azure virtual networks, not for global traffic routing.
- C. Azure Load Balancer operates at Layer 4 (transport layer) within a single region.
