Microsoft Azure Fundamentals (AZ-900)Describe Azure architecture and servicesHard
A global company requires a content delivery network (CDN) solution to deliver static and dynamic web content to users worldwide with low latency and high availability. They also need to integrate with Azure Web Apps and ensure content is cached effectively at edge locations. Which Azure service is designed for this scenario?
- AAzure Traffic Manager
- BAzure Load Balancer
- CAzure Application Gateway
- DAzure Front Door
Show answer & explanationAnswer & explanation
Correct answer: D. Azure Front Door
Azure Front Door is a global, scalable entry-point that uses the Microsoft global edge network to create fast, secure, and widely scalable web applications, offering CDN capabilities, WAF, and global load balancing for dynamic content.
Why the other options are wrong
- A. Azure Traffic Manager is a DNS-based traffic load balancer; it doesn't provide CDN capabilities or content caching at edge locations.
- B. Azure Load Balancer operates at Layer 4 (TCP/UDP) and is regional, not global, and doesn't provide CDN or WAF features.
- C. Azure Application Gateway is a web traffic load balancer (Layer 7) that includes WAF, but it is regional and does not offer global CDN capabilities like Front Door.
