What is the primary role of the Architecture Repository in TOGAF?

The primary role of the Architecture Repository in TOGAF is to store architecture artifacts. This repository serves as a centralized location for all the architectural information created during the enterprise architecture development process. It organizes and maintains various architectural artifacts, such as models, standards, guidelines, and metadata. By storing these artifacts, the Architecture Repository supports the documentation, sharing, and management of the architecture within the enterprise.

Having a structured repository is vital for maintaining consistency and ensuring that stakeholders access current and relevant architectural information. It also facilitates the reuse of architecture assets across different projects, promotes collaboration among architects, and fosters better alignment between IT and business goals.

Other choices, while relevant to enterprise activities, do not capture the primary function of the Architecture Repository. Documenting project requirements pertains more to project management activities rather than architecture governance. Tracking changes in business processes focuses on the analysis and improvement of business operations, which is not directly related to the repository's primary purpose. Implementing security measures, while critical for any architectural endeavor, is not a specific function of the Architecture Repository itself.
