Which technology is responsible for matching a name to an IP address of an application running on a host?

The correct answer is D. DNS. DNS (Domain Name System) is the technology that resolves human-readable hostnames (e.g., www.example.com) to IP addresses. It functions like a distributed phone book for the internet and local networks. A firewall (A) filters and controls network traffic based on security rules.

Explanation

DNS (Domain Name System) is the technology that resolves human-readable hostnames (e.g., www.example.com) to IP addresses. It functions like a distributed phone book for the internet and local networks. A firewall (A) filters and controls network traffic based on security rules. A proxy (B) acts as an intermediary between clients and servers but does not perform name-to-IP resolution itself. A load balancer (C) distributes incoming traffic across multiple servers to improve availability and performance. None of A, B, or C perform the name-to-IP mapping function that DNS does.
