What is the globally interconnected end-to-end set of DoD capabilities for collecting, processing, storing, disseminating and managing information on demand to warfighters, policy makers and support personnel?

• A. Defense Information Infrastructure
• B. Global Information Grid
• C. National Information Grid
• D. Global Command and Control Network

Answer: (B)

This item tests the idea of a single, globally interconnected information backbone that spans the entire information lifecycle for the DoD—collecting, processing, storing, disseminating, and managing data on demand for warfighters, policymakers, and support personnel. The Global Information Grid is the formal name for that comprehensive, end-to-end capability. It represents the DoD’s integrated network of networks, enabling interoperability, secure sharing, and timely access to information across services and partners.

The other options don’t fit as neatly. The Defense Information Infrastructure is a broader term for DoD networks in general but isn’t the official name of the global end-to-end information grid. The National Information Grid isn’t a standard DoD term. The Global Command and Control Network focuses more specifically on command and control communications rather than the full spectrum of information collection, processing, storage, and dissemination across the entire DoD.
