The Open Group TOGAF Enterprise Architecture Part 1 Exam (English) OGEA-101 Exam Dumps: Updated Questions & Answers (May 2026)

Comprehensive and Detailed Explanation

When defining the scope of an architecture, TOGAF identifies four dimensions that need to be considered:

Breadth – This dimension addresses the extent of the enterprise that will be impacted by the architecture. It answers the question: How much of the enterprise is covered? For example, does the scope include the entire enterprise, a business unit, a division, or just a single organizational function?

Depth – This refers to the level of detail to be covered. For instance, will the architecture describe high-level capabilities, or will it go into detailed system design?

Time Period – This defines the planning horizon of the architecture. It could be short-term (tactical), medium-term, or long-term (strategic).

Architecture Domains – This refers to which domains are covered: Business, Data, Application, and Technology. The scope may include all or just a subset of these domains.

Project Scope (sometimes discussed separately) – Focuses on which specific programs, portfolios, or projects will be impacted.

Among these, the dimension that specifically relates to the extent of the enterprise is Breadth.

Why the other options are incorrect

A. Architecture Domains: Refers to the domains covered (Business, Data, Application, Technology), not the extent of the enterprise.

B. Depth: Refers to the level of detail, not the enterprise extent.

C. Project: Refers to the program or initiative focus, not enterprise coverage.

This statement best describes iteration and the ADM. The ADM is iterative over the whole process between phases and within phases because it allows for feedback loops and refinements at any point in the architecture development and transition process. Iteration enables architects to address changing requirements, assumptions, constraints, and environments; to validate and improve architectures; to manage risks and issues; and to ensure stakeholder satisfaction and value realization.

Architecture governance is the practice of ensuring compliance with the enterprise architecture and its principles, standards, and goals. Architecture governance provides the means to establish, monitor, and control the architecture development and implementation processes, and to resolve any issues or conflicts that may arise. Architecture governance also ensures that all stakeholders are represented and involved in the decision-making process, and that their interests and concerns are balanced and aligned. Statements 1 and 2 highlight the value and necessity for architecture governance to be adopted within organizations, as they emphasize the importance of responsibility, accountability, fairness, and transparency in the architectural activities. Statements 3 and 4 are more related to the benefits and outcomes of having a good enterprise architecture, rather than the governance aspect.

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.

Within the TOGAF Architecture Repository, the Architecture Capability component contains the organizational and governance support needed to operate the repository and the architecture function effectively. This includes the parameters, structures, roles, processes, and control mechanisms that allow the repository and architecture practice to be governed in a disciplined way. Because of that, option D is the correct match.

The other descriptions relate to different repository components. “The architectural representation of assets in use or planned” belongs more closely to the Landscape Repository, which captures current and planned architecture assets. “The standards with which new architectures must comply” corresponds to the Standards Information Base, where relevant standards and rules are maintained. “A record of governance activity across the enterprise” aligns with the Governance Log, which tracks governance-related actions and decisions. “Authorized change requests from the Architecture Board” would be treated as governance-controlled change information rather than the Architecture Capability itself.

TOGAF distinguishes the Architecture Capability from the content held in the repository because capability is about how architecture is governed and supported, not only what architecture content is stored. Therefore, the correct answer is the parameters, structures, and processes to support governance of the Repository, which is option D.

===========

The Implementation Governance Model is a framework that defines the roles, responsibilities, processes, and standards for governing the implementation of the target architecture. It ensures that a project transitioning into implementation also smoothly transitions into appropriate Architecture Governance, which is the practice of ensuring compliance with the enterprise architecture and its principles, standards, and goals. The Implementation Governance Model is part of the Implementation and Migration Plan, which is the output of Phase F: Migration Planning of the Architecture Development Method (ADM)12 References: 1: The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 21: Phase F: Migration Planning 2: The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 50: Architecture Governance

Comprehensive and Detailed Explanation

The TOGAF ADM defines distinct objectives for Phase E (Opportunities and Solutions) and Phase F (Migration Planning).

Phase E: Opportunities and Solutions

Focuses on generating the initial Architecture Roadmap.

Identifies major work packages, Transition Architectures, and projects.

Determines if an incremental approach is needed, and defines Transition Architectures to ensure delivery of continuous business value.

Therefore:

Statement 1 (incremental approach and Transition Architectures) belongs to Phase E.

Statement 2 (initial Architecture Roadmap based on gap analysis) also belongs to Phase E.

Phase F: Migration Planning

Finalizes the Architecture Roadmap.

Develops the detailed Implementation and Migration Plan.

Ensures stakeholders understand the business value and cost of work packages and Transition Architectures.

Therefore:

Statement 3 (finalizing the Roadmap and Plan) belongs to Phase F.

Statement 4 (ensuring value and cost are understood by stakeholders) belongs to Phase F.

Correct Mapping

Phase E Objectives = Statements 1 and 2

Phase F Objectives = Statements 3 and 4

Thus the correct answer is A (1 & 2).

===========

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.

Phase G: Implementation Governance provides architectural oversight of the implementation. It ensures that the implementation conforms to the Target Architecture using Architecture Contracts and governance frameworks.

Phase H: Architecture Change Management is about maintaining the architecture lifecycle and handling new requirements, not direct implementation oversight.

Preliminary Phase is about setting up the architecture capability.

Phase A is about developing the Architecture Vision.

The Implications section describes the impact of adhering to the principle on the organization, the processes, the information systems, and the technology23. It also identifies the changes, costs, and risks that may result from applying the principle23. The Implications section helps to communicate the benefits and consequences of the principle to the stakeholders and to guide the implementation and governance of the architecture23.

The other sections of the TOGAF template for Architecture Principles are1:

•Name: This section provides a short and memorable name for the principle that represents its essence and purpose23. The name should not mention any specific technology or solution23.

•Statement: This section provides a concise and formal definition of the principle that expresses the fundamental rule or constraint that the principle imposes23. The statement should be clear, unambiguous, and testable23.

•Rationale: This section provides the reasoning and justification for the principle, explaining why it is important and how it supports the business goals and drivers23. The rationale should also link the principle to the higher-level enterprise or IT principles that it elaborates on23.
