Full Answer
B.Application Load Balancer (ALB)✓ Correct
Application Load Balancer (ALB)
An Application Load Balancer functions at the application layer (Layer 7) of the OSI model. It supports content-based routing, allowing you to route requests to different target groups based on the URL path, host header, HTTP headers, or query string parameters.
Common mistakes
Choosing NLB, which is for ultra-high performance TCP/UDP traffic but lacks Layer 7 routing.
