A perimeter network is typically used to grant internal clients access to external resources.

• A. True
• B. False
• C. Only with direct VPN
• D. Not applicable

Answer: (B)

A perimeter network (DMZ) acts as a security buffer between the Internet and an internal network. It hosts public-facing services—like web, mail, or DNS servers—so external users can reach them without touching the trusted internal systems. This setup provides isolation: if those externally accessible services are compromised, the attacker doesn’t automatically gain access to the internal network. Internal clients access external resources by routing out through the edge firewall and NAT, not by going through the DMZ to reach those external resources. So the statement is not correct because the DMZ is designed to expose services to the outside world while protecting internal resources, not to grant internal users access to external resources.
