AZ-700 Question 174
Single answerYou manage an e-commerce platform deployed in two Azure regions (East US and West Europe). The platform is accessed via a single custom domain name, and you need to ensure minimal latency for users worldwide, enable SSL offloading, and perform path-based routing at the application layer. Additionally, the solution must automatically fail over if one region goes offline. Which Azure service best meets these requirements?
- A
Azure Load Balancer
- B
Azure Traffic Manager
- C
Azure Application Gateway
- D
Azure Front Door
Show answer and explanation
Correct answer: D
Explanation
Because you require global distribution, SSL offloading, path-based routing, and automatic failover, Azure Front Door is the recommended choice. It offers global routing at Layer 7 and ensures customers connect to the nearest operational region with minimal latency. For more details, see the Microsoft Azure Front Door documentation.
- A. Incorrect.
Azure Load Balancer is primarily a regional Layer 4 (TCP/UDP) load balancer. It does not provide global routing or application-layer capabilities like SSL offloading and path-based routing across multiple regions.
- B. Incorrect.
Azure Traffic Manager is a global DNS-based load balancer that can direct traffic to different regions, but it does not provide built-in SSL offloading or path-based routing at Layer 7. It primarily manages traffic flow at the DNS level.
- C. Incorrect.
Azure Application Gateway is a regional Layer 7 load balancer with features like SSL offloading and path-based routing, but it functions within a single region and does not provide global failover or global routing out of the box.
- D. Correct.
Azure Front Door is a global, Layer 7 service designed for high-performance and availability across multiple regions. It supports SSL offloading, path-based routing, and automatic failover, making it the best fit for the described scenario.
