OGEA-101 Exam Dumps - The Open Group Enterprise Architecture Questions and Answers

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.

The four dimensions used to scope an architecture are Breadth, Depth, Time Period, and Architecture Domains1, p. 8.

Breadth refers to the extent of the enterprise covered by the architecture, which can range from a specific business unit to the entire organization1, p. 8.

Depth refers to the level of detail and completeness of the architecture, which can vary depending on the purpose, scope, and stakeholders of the architecture1, p. 8.

Time Period refers to the temporal aspects of the architecture, such as the current state, the target state, and the transition plan1, p. 8.

Architecture Domains refers to the classification of the architecture into four domains: Business, Data, Application, and Technology1, p. 8.

These four dimensions help define the scope and boundaries of the architecture and ensure that it meets the needs and expectations of the stakeholders.

Comprehensive and Detailed Explanation

Ensure that the business value and cost of work packages and Transition Architectures is understood by key stakeholders

This is the objective of Phase F: Migration Planning, where the Implementation and Migration Plan is developed, addressing costs, business value, and stakeholder concerns.

Ensure conformance with the Target Architecture by implementation projects

This is the focus of Phase G: Implementation Governance, which oversees implementation projects, ensuring they align with and conform to the Target Architecture through architecture contracts.

Ensure that the architecture development cycle is maintained

This belongs to Phase H: Architecture Change Management, which ensures the architecture remains relevant, and that the ADM cycle continues in response to new requirements and changes.

Ensure that the Architecture Governance Framework is executed

Also part of Phase H: Architecture Change Management, where governance is continuously applied to manage change effectively.

Correct Mapping

1 → F

2 → G

3 → H

4 → H

Which corresponds to Option A (1F – 2G – 3H – 4H).

Why the other options are incorrect

B. (1H – 2F – 3F – 4G): Incorrect assignment of phases; for example, conformance is not part of Phase F.

C. (1G – 2H – 3H – 4F): Misplaces objectives; conformance is not Phase H, and governance execution is not Phase F.

D. (1F – 2G – 3G – 4H): Incorrect because maintaining the ADM cycle (3) is not Phase G, but Phase H.
