Which device allows inbound connections to be initiated from the Internet and relays or proxies them to internal resources?

• A. NAT Gateways
• B. Internet Gateways
• C. API Gateway
• D. XML Gateway

Answer: (B)

An Internet Gateway serves as the entry point that allows traffic initiated from the Internet to reach resources inside a private network. It provides a path for inbound connections into the network and works with routing rules and security settings to forward that traffic toward internal resources, often through a public IP or a public-facing load balancer that then directs requests to private servers. This contrasts with NAT gateways, which are designed for internal hosts to reach the Internet (outbound access) and do not serve as a gateway for inbound Internet-initiated connections. API gateways are focused on exposing and managing API traffic, not providing a general mechanism for forwarding arbitrary Internet requests to internal resources. XML gateways handle XML message processing rather than general network access. So, the Internet Gateway is the device that fits the described role.
