AZ-305 Question 243
Single answerYou manage a globally distributed e-commerce platform that operates in three Azure regions. The business requires a single global endpoint that can direct users to the nearest region based on latency, provide SSL termination at an edge location, and support path-based routing for different backend pools. Which Azure service should you implement to meet these requirements?
- A
Azure Standard Load Balancer
- B
Azure Front Door
- C
Azure Application Gateway
- D
Azure Traffic Manager
Show answer and explanation
Correct answer: B
Explanation
Azure Front Door is specifically designed for global, Layer 7 load balancing with advanced routing features, including SSL termination at the edge, latency-based routing, and path-based routing. For more information on using Azure Front Door for multi-region web applications, see the official Azure documentation: https://learn.microsoft.com/en-us/azure/frontdoor/front-door-overview.
- A. Incorrect.
Azure Standard Load Balancer works at Layer 4 (TCP/UDP) and does not provide global routing, SSL termination, or path-based routing. It is primarily for regional load balancing of virtual machines (VMs) within a single region.
- B. Correct.
Azure Front Door provides global, Layer 7 load balancing with SSL termination at the edge. It supports latency-based routing and path-based routing rules, making it suitable for multi-region e-commerce scenarios with a single global endpoint.
- C. Incorrect.
Azure Application Gateway is a regional Layer 7 load balancer that supports SSL offload and path-based routing, but it does not provide global traffic distribution or latency-based routing across multiple regions.
- D. Incorrect.
Azure Traffic Manager uses DNS-based global routing to direct traffic to different endpoints based on various routing algorithms (including latency). However, it does not provide edge SSL termination or path-based routing functionality. It directs clients to a region but lacks the layer capabilities that Azure Front Door provides.
