An Architecture Board is an executive-level group responsible for the review and maintenance of the strategic architecture and all of its sub-architectures1. It is a key element in a successful Architecture Governance strategy2.
An Architecture Board is typically made responsible, and accountable, for achieving some or all of the following goals2:
Providing the basis for all decision-making with regard to the architectures Consistency between sub-architectures Establishing targets for re-use of components Flexibility of the Enterprise Architecture: To meet changing business needs To leverage new technologies Enforcement of Architecture Compliance Improving the maturity level of architecture discipline within the organization Ensuring that the discipline of architecture-based development is adopted Supporting a visible escalation capability for out-of-bounds decisions Therefore, the correct answer is option D, which captures one of the goals of an Architecture Board as stated in the TOGAF Standard, Version 9.22.
Option A is incorrect, because conducting assessments of the maturity level of architecture discipline within the organization is not a direct responsibility of an Architecture Board, but rather a part of the Architecture Capability Framework3.
Option B is incorrect, because allocating resources for architecture projects is not a direct responsibility of an Architecture Board, but rather a part of the Architecture Governance Framework4.
Option C is incorrect, because creating the Statement of Architecture Work is not a direct responsibility of an Architecture Board, but rather a part of the Architecture Development Method5. References:

The following activities are part of Risk Management:
* Initial risk assessment
* Risk mitigation and residual risk assessment
* Risk monitoring
Risk Management is the process of identifying, assessing, and responding to risks that may affect the achievement of the enterprise's objectives. Risk Management involves balancing positive and negative outcomes resulting from the realization of either opportunities or threats. Reference: The TOGAF Standard | The Open Group Website, Section 3.3.3 Risk Management.

According to the TOGAF standard, the Target Architecture is the description of a future state of the architecture being developed for an organization. It should be aligned with the Architecture Vision, Principles, and Requirements that have been agreed with the stakeholders. To address the incompatibilities between key stakeholder preferences, the TOGAF standard recommends creating and evaluating multiple alternative Target Architectures that meet different sets of criteria. These criteria should reflect the value preferences and priorities of the stakeholders, as well as the business drivers and objectives. The alternative Target Architectures should be illustrated using a set of architecture views that show the impact of each alternative on the business, data, application, and technology domains. The impact on planned projects should also be identified and analyzed. The strengths and weaknesses of each alternative should be understood and documented. A formal stakeholder review should then be conducted to decide which alternative is the most fit for purpose and should be moved forward with. The funding required for implementing the chosen alternative should also be determined and secured. References:

This statement about Requirements Management is most correct because it reflects the central role of Requirements Management and stakeholder engagement in the ADM cycle. Requirements Management is not a step of all ADM Phases, but rather an ongoing process that ensures that all relevant requirements are elicited, analyzed, prioritized, and addressed throughout the architecture development and transition.
Stakeholder engagement is also a continuous activity that involves identifying, communicating, and managing stakeholder expectations and concerns. Reference: The TOGAF Standard | The Open Group Website, Section 3.1 Introduction to the ADM.

In TOGAF, when an enterprise undergoes a significant strategic shift-particularly one initiated by executive leadership without a clearly defined scope, vision, or objectives-the correct starting point is always Phase A:
Architecture Vision, and only after a formal Request for Architecture Work is created or updated. The scenario explicitly states that the CEO has approved a request for architecture change but has not defined scope, constraints, or direction. This aligns precisely with TOGAF guidance that Phase A must establish the high-level vision, stakeholder concerns, business drivers, and initial requirements before moving into the detailed architecture development phases (B, C, D).
Answer choice C reflects this: it requires producing a new Request for Architecture Work and developing a new Architecture Vision, which is the foundational step for any enterprise-wide transformational effort.
TOGAF also requires application of the trade-off method to balance stakeholder needs in the Vision phase before detailed architectures are designed.
Choices A and D incorrectly assume architecture definition can begin without a clear approved vision. Choice B focuses solely on Technology Architecture, which contradicts TOGAF's requirement that Business Architecture must lead the effort during major transformation.
Thus, the only answer compliant with TOGAF ADM is C.
