Which term is described as the front line defense between the DoD and the Internet?

• A. USAF Gateway Router - IP/MPLS
• B. IMS
• C. AFLCMC
• D. Cyber Mission Force

Answer: (A)

The front line defense between the DoD and the Internet is the network boundary device that sits at the edge and enforces security before traffic enters or leaves the DoD networks. A gateway router at the edge handles traffic ingress and egress, applying access controls, routing decisions, and often VPN termination to ensure only authorized traffic crosses into the DoD environment. In the Air Force setup, the term that describes this role is the USAF Gateway Router - IP/MPLS, which serves as that boundary device and enforces policy at the edge of the network. The other options refer to a system or organization rather than a boundary device, so they don’t fit the role of the frontline protector between DoD networks and the Internet. This gateway function is what provides the first line of defense by controlling and monitoring what can enter or leave the trusted network.
