Which device provides content caching, traffic scrubbing, IP masking, and load balancing for inbound traffic?

• A. XML Gateway
• B. WAF
• C. API Gateway
• D. Reverse Proxy (Inbound traffic)

Answer: (D)

A reverse proxy sits at the edge of the network and handles inbound requests on behalf of the real servers. It can cache static content so responses arrive quickly without always touching the backend. It can scrub traffic by inspecting for threats and blocking or cleaning suspicious requests before they reach applications. It masks internal IPs by presenting its own address to clients, keeping the behind-the-scenes topology hidden. And it can load-balance across multiple backend servers, distributing requests to maintain performance and high availability. While other devices like a WAF, API gateway, or XML gateway serve important purposes, they don’t typically combine all four capabilities for inbound traffic in the same way a reverse proxy does.
