TOGAF Practice Exam 2025 – The All-in-One Guide to Master The Open Group Architecture Framework!

The correct answer is the III-RM (Integrated Information Infrastructure Reference Model). This model plays a crucial role in Phase C of the TOGAF Architecture Development Method (ADM), where the emphasis is on developing the Information Systems Architecture. The III-RM specifically focuses on the application layer, outlining how application components and services interact within an enterprise. It provides a structured approach to understanding the relationships between different application components and ensures that these applications effectively support the business processes.

The III-RM addresses the integration of applications, aiding architects in ensuring that the systems in place are interoperable and can efficiently communicate with one another. This model provides a framework that can guide decision-making related to application architecture and the selection of appropriate technologies to ensure alignment with business needs.

Other options, such as the ARTS data model and business rules or job descriptions, do not serve as reference models that focus holistically on application-level components and services in the same way. Meanwhile, the TOGAF Technical Reference Model provides a more general framework that encompasses various technology components rather than focusing exclusively on applications. Thus, the III-RM emerges as the most relevant resource within the context of application-level components in Phase C of TOGAF.
