Application Load Balancer — AWS Solutions Architect Associate Practice Questions
The Application Load Balancer (ALB) operates at Layer 7 of the OSI model and is designed for HTTP and HTTPS traffic, offering content-based routing based on URL path, hostname, HTTP headers, and query strings. The Solutions Architect Associate exam frequently tests ALB in scenarios requiring path-based or host-based routing to direct traffic to different microservices or target groups within the same load balancer. ALB supports WebSocket connections, HTTP/2, and native integration with AWS WAF for web application security. Understanding when to choose ALB over a Network Load Balancer, particularly when application-layer routing or TLS termination is required, is a common exam decision point.
