Why each option
A DMZ (Demilitarized Zone) is a network segment that hosts publicly accessible services like web and DNS servers, isolated from the internal network.
A VPN (Virtual Private Network) creates encrypted tunnels for secure remote access to internal resources and does not serve as a hosting zone for public-facing servers.
MMZ is not a recognized standard networking zone or architecture term; it appears to be a distractor.
A VLAN (Virtual LAN) is a Layer 2 logical network segmentation technology used within an organization and does not specifically define a zone for publicly accessible internet-facing servers.
The DMZ is a perimeter network segment sitting between the public internet and the internal corporate network, typically enforced by firewalls on both sides. Placing DNS and web servers in the DMZ allows external internet users to reach them while preventing direct access to internal systems if a public-facing server is compromised.
