Explanation

A DMZ (Demilitarized Zone) is a network security architecture pattern - a subnet that sits between the public internet and the internal private network. It hosts internet-facing services (web servers, mail servers, DNS) that must be publicly accessible while isolating them from the internal network. If a DMZ host is compromised, the attacker still faces another firewall before reaching internal systems. It is not a topology type (B), physical control (C), or encryption method (D). It is achieved through firewall rules and segmentation.
