All Navy inter-network communications traffic must pass through which router?

• A. Inline Network Encryption (INE)
• B. TRANSEC
• C. CT Core Router
• D. VoIP

Answer: (C)

Inter-network traffic is centralized through a single backbone device that routes and governs data moving between different networks. The CT Core Router serves that role in Navy networks, acting as the central transit point where traffic from one network is forwarded to another, with routing decisions, policy enforcement, and monitoring applied at the boundary between domains. This setup ensures that all cross-network communications pass through a controlled, auditable gateway.

Inline Network Encryption sits in the data path to encrypt and decrypt traffic but doesn’t perform the overall inter-network routing function. TRANSEC concerns transmission security policies and mechanisms rather than acting as the core routing hub. VoIP is a service for voice communication, not a routing device.
