DSN stands for which network?

• A. Defense Switch Network
• B. Defense Satellite Network
• C. Digital Security Network
• D. Data Switching Network

Answer: (A)

DSN refers to the Defense Switch Network, the DoD’s dedicated circuit-switched network used for secure, priority voice communications between defense installations and commands. This network provides reliable, direct connections for mission-critical calls and limited data services, distinct from satellite-based systems or generic data networks. The term Defense Satellite Network would imply satellite links, which is a different system, while Digital Security Network or Data Switching Network are not the standard DoD designation for DSN.
