When designing software, DoD policy requires integrated architectures including operational architecture, systems architecture, and which other architecture?

• A. Operational architecture
• B. Systems architecture
• C. Security architecture
• D. Technical architecture

Answer: (D)

The concept being tested is how DoD policy organizes architecture into a complete set of integrated views: what the system must do in operation, how the components fit together, and the technical environment that makes everything interoperable. The technical architecture specifies the standards, platforms, interfaces, data models, and security services that enable diverse components to work together across programs. It translates operational needs and system designs into concrete technology choices, ensuring interoperability, scalability, and reuse. Security architecture is important for protecting information and operations, but within this framework it isn’t the third integrated architecture alongside operational and systems. The missing piece that completes the three-view approach is the technical architecture.
