OGEA-101 The Open Group TOGAF Enterprise Architecture Part 1 Exam (English) Free Practice Exam Questions (2026 Updated)

Risk management is a generic technique that can be applied across all phases of the Architecture Development Method (ADM), as well as in the Preliminary Phase and the Requirements Management Phase2. Risk management involves the following steps1:

•Risk identification: This step involves identifying the potential risks that may affect the architecture project, such as technical, business, organizational, environmental, or legal risks. The risks can be identified through various sources, such as stakeholder interviews, workshops, surveys, checklists, historical data, or expert judgment.

•Risk classification: This step involves categorizing the risks based on their nature, source, impact, and priority. The risks can be classified according to different criteria, such as time, cost, scope, quality, security, or compliance. The classification helps in prioritizing the risks and allocating resources and efforts to address them effectively.

•Initial risk assessment: This step involves assessing the likelihood and impact of each risk, and determining the initial level of risk. The likelihood is the probability of the risk occurring, and the impact is the severity of the consequences if the risk occurs. The initial level of risk is the product of the likelihood and impact, and it indicates the urgency and importance of the risk. The initial risk assessment helps in identifying the most critical risks that need immediate attention and mitigation.

Business scenarios are a technique for capturing, clarifying, and communicating the functional and non-functional requirements of a system. Business scenarios describe the business environment, the actors involved, the desired outcomes, and the processes or rules that govern the behavior of the system. Business scenarios are useful for ensuring that the architecture addresses the real needs and concerns of the stakeholders, and for validating and testing the architecture against expected situations. Business scenarios are developed in Phase A: Architecture Vision of the ADM cycle, and refined and updated throughout the other phases3 References: 3: The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 26: Business Scenarios : The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 18: Phase A: Architecture Vision

The illustration shows an architecture development cycle based on the TOGAF ADM (Architecture Development Method), which is a method for developing and managing an enterprise architecture1.

The ADM consists of nine phases, each with a specific purpose and output. The phases are1:

Preliminary Phase: To prepare and initiate the architecture development cycle, including defining the architecture framework, principles, and governance.

Phase A: Architecture Vision: To define the scope, vision, and stakeholders of the architecture initiative, and to obtain approval to proceed.

Phase B: Business Architecture: To describe the baseline and target business architecture, and to identify the gaps between them.

Phase C: Information Systems Architectures: To describe the baseline and target data and application architectures, and to identify the gaps between them.

Phase D: Technology Architecture: To describe the baseline and target technology architecture, and to identify the gaps between them.

Phase E: Opportunities and Solutions: To identify and evaluate the opportunities and solutions for implementing the target architecture, and to define the work packages and transition architectures.

Phase F: Migration Planning: To finalize the implementation and migration plan, and to ensure alignment with the enterprise portfolio and project management.

Phase G: Implementation Governance: To provide architecture oversight and guidance for the implementation projects, and to manage any architecture change requests.

Phase H: Architecture Change Management: To monitor the changes in the business and technology environment, and to assess the impact and performance of the architecture.

In addition to these phases, there is a central process called Requirements Management, which is labeled as item 1 in the illustration. This process operates throughout the ADM cycle, and its purpose is to manage the architecture requirements throughout the architecture development, ensuring that they are aligned with the business requirements and the stakeholder concerns2.

Therefore, the description that matches the phase of the ADM labeled as item 1 is C. Operates the process of managing architecture requirements.

According to the TOGAF Standard, Version 9.2, an architecture view is a representation of a system from the perspective of a related set of concerns1. It consists of one or more architecture models that demonstrate how the system addresses the stakeholder concerns1.

An architecture viewpoint is a specification of the conventions for constructing and using an architecture view to address specific stakeholder concerns1. It defines the perspective, scope, notation, and techniques for creating an architecture view of a system1.

Architects can present architecture views and viewpoints to stakeholders to extract hidden agendas, principles, and requirements that could impact the final Target Architecture, because23:

Architecture views and viewpoints help to communicate and visualize the architecture in a way that is meaningful and relevant to different stakeholders, addressing their specific interests and needs.

Architecture views and viewpoints help to elicit and validate the stakeholder concerns and requirements, ensuring that they are aligned with the business goals and objectives, and that they are consistent and feasible within the architecture context.

Architecture views and viewpoints help to identify and resolve any conflicts, gaps, or trade-offs among the stakeholder concerns and requirements, ensuring that they are balanced and prioritized in the architecture design and decision-making.

Architecture views and viewpoints help to demonstrate and verify the value and benefits of the architecture to the stakeholders, ensuring that they are satisfied and committed to the architecture outcome and governance.

3: The TOGAF Standard, Version 9.2, Chapter 31: Architectural Artifacts, Section 31.1: Basic Concepts

Architecture Principles are general rules and guidelines that inform and support the way in which an organization sets about fulfilling its mission. They reflect a level of consensus among the various elements of the enterprise, and form the basis for making future IT decisions. One of the purposes of Architecture Principles is to establish a common understanding of how to control the business in pursuit of strategic objectives, by providing a framework for evaluating and agreeing on the changes that affect the enterprise’s architecture3 References: 3: The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 23: Architecture Principles : The TOGAF Standard, Version 9.2, Part IV: Architecture Content Framework, Chapter 31: Architecture Principles

An Architecture Contract is a deliverable that specifies the responsibilities and obligations of the parties involved in the implementation and governance of an architecture. It ensures a system of continuous monitoring to check integrity changes decision-making and audit of all architecture-related activities. Reference: The TOGAF® Standard | The Open Group Website, Section 3.3.4 Architecture Contracts.

In the context of TOGAF, a stakeholder is any individual, team, or organization who has interests in, or concerns relative to, the outcome of the architecture. Concerns are those interests which pertain to any aspect of the system’s functioning, development or operation, including considerations such as performance, reliability, and security1. References:

•The TOGAF Standard, Version 9.2 - Definitions - The Open Group

In TOGAF, draft deliverables are those that are not yet finished or approved. They are work-in-progress versions that may have version numbers like 0.1, 0.5, or 0.9.

Once reviewed and approved, they become final deliverables.

“Modeling these items would help the clarification process, and in particular would highlight any ambiguities or conflicts that involved trade-offs and/or prioritization… the architecture principles… likewise help clarify ambiguities or conflicts that involve trade-offs.” Open Group Publications

According to the TOGAF standard, the need for the ADM process to be governed is to ensure that the architecture development and implementation activities are conducted in a consistent, coherent, and compliant manner1. Governance provides the means to verify that the method is being applied correctly and effectively, and that the architecture deliverables and artifacts meet the quality and standards criteria1. Governance also enables the management of risks, issues, changes, and dependencies that may arise during the ADM process1.

Some of the benefits of governing the ADM process are2:

•Improved alignment of the architecture with the business strategy and objectives

•Enhanced stakeholder engagement and communication

•Increased reuse and integration of architecture assets and resources

•Reduced complexity and duplication of architecture efforts

•Increased agility and adaptability of the architecture to changing needs and requirements

•Improved compliance and auditability of the architecture outcomes and outputs

“In addition to the method itself being iterative, there is also iteration within the ADM cycle, both among the individual phases and among the steps within a phase.” www.opengroup.org

The chart illustrates an important TOGAF concept: ADM phases can operate concurrently or iteratively rather than strictly sequentially. The diagram shows Phase A activities occurring first, after which the architecture development phases (Business, Data, Application, and Technology Architectures) overlap in time. This overlap demonstrates how architecture development work may proceed in parallel as information becomes available, allowing architects to refine and coordinate the candidate architecture more efficiently.

TOGAF explicitly supports iteration and concurrency across ADM phases. While the phases are presented in a logical order, they are not intended to be executed in a rigid step-by-step sequence in all situations. Instead, architects may work across several phases simultaneously to address dependencies, refine requirements, and accelerate the development of the candidate architecture and roadmap.

Option A best reflects this principle because it acknowledges that phases may run together as part of an iterative architecture development process until a coherent candidate architecture is produced and validated. Option B is incorrect because TOGAF does not mandate the use of specific project management tools such as Gantt charts. Option C is incorrect because the ADM is not strictly sequential. Option D is incorrect because the duration of phases is not fixed in TOGAF.

Therefore, the chart illustrates the concept that ADM phases may be executed concurrently to develop and validate the candidate architecture.

The Enterprise Continuum consists of two complementary concepts: the Architecture Continuum and the Solutions Continuum1. The Architecture Continuum provides a consistent way to describe and understand the generic and reusable architecture building blocks, such as models, patterns, and standards, that can be applied and tailored to specific situations2. The Solutions Continuum provides a consistent way to describe and understand the specific and implemented solution building blocks, such as products, services, and components, that realize the architecture building blocks3. The Enterprise Continuum enables the reuse and integration of architecture and solution assets across different levels of abstraction, scope, and detail, ranging from foundation architectures to organization-specific architectures1.

The Enterprise Continuum is used when developing an enterprise architecture to support the following activities1:

•Selecting relevant architecture and solution assets from the Architecture Repository or other sources, based on the business drivers, goals, and requirements

•Adapting and customizing the architecture and solution assets to suit the specific needs and context of the enterprise

•Defining and developing the target architecture and the architecture roadmap, based on the gaps and opportunities identified between the baseline and the target states

•Defining and developing the implementation and migration plan, based on the architecture roadmap and the solution building blocks

•Governing and managing the architecture and solution assets throughout the architecture lifecycle, ensuring their quality, consistency, and compliance

The Architecture Requirements Specification is one of the TOGAF deliverables that provides a set of quantitative statements that outline what an implementation project must do in order to comply with the architecture12. It is a companion to the Architecture Definition Document, which provides a qualitative view of the solution and aims to communicate the intent of the architect. The Architecture Requirements Specification provides a quantitative view of the solution, stating measurable criteria that must be met during the implementation of the architecture3. It typically forms a major component of an implementation contract or contract for more detailed Architecture Definition4. References:

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 aligns with the TOGAF Architecture Repository model where:

A (Architecture Requirements Repository) contains requirements that drive architecture work.

B (Solutions Repository) stores the building blocks or solutions that support the architecture.

C (Architecture Landscape) represents the architecture assets that depict the current, transition, and target architecture states across the enterprise

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.
