Which term describes the component that connects shipboard users to external networks and WANs?

• A. Increment I
• B. ADNS
• C. CaS
• D. Increment II

Answer: (B)

The key idea is identifying the component that acts as the gateway between the ship’s local network and external networks and WANs. This role is filled by the ADNS system, which serves as the edge that connects onboard users to the wider DoD networks and the Internet.

ADNS ties the ship’s internal LAN to satellite and other long-haul links, handling the routing and access needed for shipboard users to reach external resources. It provides the path to WANs, manages network services at the edge, and enforces policies that keep traffic flowing securely and efficiently.

Other options refer to upgrade stages or different subsystems and do not describe the gateway function that links shipboard users to external networks and WANs, so they don’t fit as well.
