A specialized type of DMZ created for partner organizations to access over a wide area network is called what?

• A. Extranet
• B. Dual-Home Firewall
• C. Multi-Homed Firewall
• D. Boundary Control

Answer: (A)

Extranet is a private network that extends part of the organization's internal network to authorized external partners over a WAN. It uses a DMZ to host services that partners need—such as a partner portal or API—while keeping the rest of the internal network protected. Access is controlled with authentication, encryption, and strict segmentation, ensuring partners can reach only what they’re permitted to see. This makes it the right term for a specialized DMZ created for partner organizations to access over a wide area network. The other concepts describe firewall topology rather than enabling partner access: a dual‑home (or multi‑homed) firewall refers to a firewall connected to multiple networks, often for redundancy, not specifically about external partner access; boundary control is not the standard term used for this scenario.
