AZ-900 Practice Question 75: Load Balancer vs Application Gateway

Microsoft Azure Fundamentals (AZ-900) · Test 8 · question 5 of 10

Azure Architecturemedium

A web app team needs incoming requests split by URL path (/images to one backend pool and /api to another), and they want TLS terminated at the load-balancing layer itself rather than on every backend server. Which Azure service meets both requirements?

Show answer and explanation

Answer:

  • A. Azure Application Gateway

Application Gateway is a web traffic load balancer that operates at the application layer (OSI layer 7), making routing decisions based on HTTP attributes like the URL path, and it supports SSL/TLS termination at the gateway; both requirements in the stem map directly onto its two headline features.

Option B, Azure Load Balancer, operates at layer 4 on IP address and port alone; it never inspects the HTTP request, so it cannot route by URL path or terminate TLS. Option C, Traffic Manager, is a DNS-based service that directs clients to an entire endpoint before any HTTP request is made, so it has no visibility into a URL path and does no TLS work at all. Option D, Front Door, is Microsoft's global edge service for routing and failing over between entire regional deployments of an app, not the regional application-layer balancer this single-region scenario calls for.
