What is the benefit of a common data model in C2?

• A. It creates data silos
• B. It makes data sharing harder across systems
• C. It increases inconsistencies in data definitions
• D. It enables interoperability across systems, with consistent data definitions and easier data sharing

Answer: (D)

A common data model standardizes data definitions, structures, and semantics so every component uses the same language. In a C2 environment, this enables interoperability across systems and makes data sharing much easier because telemetry, commands, status, and indicators can be interpreted consistently regardless of the source. With consistent definitions, tools can integrate, correlate, and automate across different components without bespoke adapters, reducing errors and speeding up response.

The other options describe the opposite of what a common data model provides: creating data silos, making sharing harder, and increasing inconsistencies in data definitions.
