Which component connects shipboard users to external networks and WANs?

• A. Domain Controller Replication
• B. CaS
• C. Increment I
• D. ADNS

Answer: (D)

Connecting shipboard users to external networks requires a gateway that handles routing, uplinks, and the provision of external services. The Automated Digital Network System is designed exactly for that role on Navy platforms, coordinating the ship’s internal LAN traffic with external networks and WANs through satellite and other uplinks, while also providing essential services like DNS and network management. This makes it the right fit for connecting shipboard users to outside networks.

Domain Controller Replication is about keeping Active Directory data consistent across domain controllers, which happens inside a network rather than bridging to external networks. Increment I and CaS do not represent the gateway function that links the ship’s local network to external networks and WANs, so they don’t fit this purpose.
