The primary function of an application load balancer is to ?

• A. Store secrets securely
• B. Route and balance HTTP/HTTPS traffic to backend services
• C. Provide DNS resolution
• D. Terminate TLS at the edge

Answer: (B)

An application load balancer’s main job is to distribute incoming HTTP/HTTPS requests across backend services in a way that balances load and keeps the system responsive. It operates at the application layer, so it can inspect request details like URLs and headers and route traffic to the most appropriate backend service, while also checking the health of targets to avoid directing traffic to unhealthy instances. This makes it the best description of its primary function: routing and balancing HTTP/HTTPS traffic to backend services. Other options describe useful capabilities in related systems (secret storage, DNS resolution, TLS termination), but they are not the core purpose of an application load balancer.
