Which of the following is NOT one of the Federal Enterprise Architecture models?

• A. Security Reference
• B. Performance Reference
• C. Data Reference
• D. Service Component Reference

Answer: (A)

Federal Enterprise Architecture uses a set of reference models to describe different aspects of the enterprise. The models that are commonly used include the Performance Reference Model, which ties resources to outcomes and measures, the Data Reference Model, which standardizes data assets and how data is shared, and the Service Component Reference Model, which defines reusable service components and their interfaces to promote interoperability. The item named Security Reference is not part of the standard FEAF reference-model lineup; security is treated as a crosscutting concern and is addressed within the other models and through security guidance rather than as its own separate model. Therefore, Security Reference does not belong to the FEAF models.
