According to the TOGAF Standard, 10th Edition, architecture governance is ''the practice by which enterprise architectures and other architectures are managed and controlled at an enterprise-wide level'' 1. Architecture governance ensures that the architecture development and implementation are aligned with the strategic objectives, principles, standards, and requirements of the enterprise, and that they deliver the expected value and outcomes. Architecture governance also involves establishing and maintaining the architecture framework, repository, board, contracts, and compliance reviews 1. The other options are not correct, as they are not the term used by the TOGAF Standard to describe the practice by which the enterprise architecture is managed and controlled at an enterprise-wide level. Corporate governance is ''the system by which an organization is directed and controlled'' 2, and it covers aspects such as leadership, strategy, performance, accountability, and ethics. IT governance is ''the system by which the current and future use of IT is directed and controlled'' 2, and it covers aspects such as IT strategy, policies, standards, and services. Technology governance is ''the system by which the technology decisions and investments are directed and controlled'' 3, and it covers aspects such as technology selection, acquisition, deployment, and maintenance.

One of the key responsibilities of an Architecture Board within the context of TOGAF is to achieve consistency between sub-architectures. This board is typically responsible for overseeing the development and maintenance of the enterprise architecture, ensuring that it aligns with the organization's overall strategy and objectives. They play a critical role in ensuring that all sub-architectures (like Business Architecture, Data Architecture, Application Architecture, and Technology Architecture) work together cohesively and support the overall enterprise architecture vision and strategy.

Business scenarios are a technique recommended by the TOGAF ADM for use in developing an Architecture Vision document12. Business scenarios are a means of capturing the business requirements and drivers, the processes and actors involved, and the desired outcomes and measures of success34. Business scenarios help to create a common vision and understanding among the stakeholders, and to identify and validate the architecture requirements . Business scenarios also provide a basis for analyzing the impact and value of the proposed architecture. Reference:

The table describes the output, outcome, and essential knowledge of an ADM phase that oversees the implementation of changes necessary to reach the adjusted target state. This corresponds to Phase G, also known as Implementation Governance, which ensures that the architecture defined in earlier phases is realized, and it oversees the development and implementation of projects to align with this architecture. The essential knowledge required during this phase includes understanding constraints on the implementation team and adjusting stakeholder priority and preference in response to success, value, effort, and risk of change.

The scope of an architecture is the extent and level of detail of the architecture work. The scope of an architecture can be defined along four dimensions: project, breadth, depth, and architecture domains. The project dimension considers the boundaries and objectives of the architecture project, such as the time frame, budget, resources, and deliverables. The breadth dimension considers the coverage and completeness of the architecture across the enterprise, such as the organizational units, business functions, processes, and locations. The depth dimension considers the level of detail and specificity of the architecture, such as the granularity, abstraction, and precision of the architectural elements and relationships. The architecture domains dimension considers the aspects or segments of the architecture, such as the business, data, application, and technology domains.

Therefore, the depth dimension is the one that considers to what level of detail the architecting effort should go.
