OGEA-101 TOGAF Enterprise Architecture Part 1 Exam (English) Questions and Answers

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.

The ability to develop, use, and sustain the architecture of a particular enterprise using architecture to govern change is an EA Capability. An EA Capability is a set of skills, processes, roles, responsibilities, tools, and techniques that enable an enterprise to successfully develop and maintain its Enterprise Architecture and achieve its desired outcomes. An EA Capability is part of an enterprise’s overall capability portfolio and should be aligned with its strategy and objectives. Reference: The TOGAF® Standard | The Open Group Website, Section 3.2 Preliminary Phase.

The purpose of Enterprise Architecture is to guide effective change by providing a coherent and consistent view of the enterprise’s current and future state, as well as the roadmap and principles for achieving it. Enterprise Architecture helps to align business and IT strategies, optimize resources and investments, reduce complexity and risks, enhance agility and innovation, and deliver value to stakeholders. Reference: The TOGAF® Standard | The Open Group Website, Section 1.3 Executive Overview.

The TOGAF standard divides Enterprise Architecture into four primary architecture domains: business, data, application, and technology. These domains represent different aspects of an enterprise and how they relate to each other. The business domain defines the business strategy, governance, organization, and key business processes. The data domain describes the structure of the logical and physical data assets and data management resources. The application domain provides a blueprint for the individual applications to be deployed, their interactions, and their relationships to the core business processes. The technology domain describes the logical software and hardware capabilities that are required to support the deployment of business, data, and application services. Other domains, such as motivation, security, or governance, may span across these four primary domains. References:

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

Let’s examine each statement against the TOGAF ADM principles:

All ADM activities are carried out within an iterative cycle of continuous architecture definition and realization

Correct. The ADM is iterative in three dimensions: across the cycle, between levels (enterprise, segment, capability), and within phases. This means architecture development is never linear but part of a continuous cycle of definition and realization.

The Requirements Management phase is a continuous phase

Correct. Requirements Management is central to the ADM cycle. It operates continuously, ensuring requirements are identified, stored, and addressed throughout all phases, not only in a single step.

Output from an early phase may be modified in a later phase

Correct. The ADM is iterative and allows feedback between phases. For example, new requirements identified in later phases may lead to modifications of deliverables from earlier phases.

When a phase starts, the previous phase closes

Incorrect. The ADM is not strictly sequential. Phases can overlap, iterate, and provide feedback loops. One phase starting does not imply that the previous phase is closed; instead, phases interact dynamically.

Correct Mapping

Statements 1, 2, and 3 are correct.

Statement 4 is incorrect.

Correct answer is B (1, 2 & 3).

Why the other options are incorrect

A (2, 3 & 4): Includes statement 4, which is incorrect.

C (1, 2 & 4): Includes statement 4, which is incorrect.

D (1, 3 & 4): Includes statement 4, which is incorrect.

According to the TOGAF Standard, 10th Edition, the rationale section of the architecture principles template should highlight the business benefits of adhering to the principle, as well as the business risks of not adhering to it 1. The rationale section should explain the reasoning behind the principle, and provide evidence or arguments to support it. The rationale section should also link the principle to the business drivers, goals, and objectives of the enterprise, and show how the principle contributes to the value and success of the enterprise. The other options are not correct, as they have different purposes in the architecture principles template. The name section should provide a short and memorable name for the principle, such as “Information is an Asset” or “Business Continuity” 1. The statement section should provide a concise and formal statement of the principle, such as “The enterprise’s information is recognized as a core asset, and is managed accordingly” or “The enterprise’s ability to provide critical services and products must be maintained in the event of a disaster” 1. The implications section should identify the impact of the principle on the enterprise, such as the changes, costs, benefits, and risks that may result from applying or violating the principle 1.

Risk is defined as the effect of uncertainty on objectives, according to the ISO 31000 standard, which provides principles and guidelines for risk management1 Risk can be positive or negative, depending on whether the uncertainty affects the achievement or the failure of the objectives. Risk can also be expressed in terms of likelihood and impact, which indicate the probability and the consequence of the risk occurrence. Risk management is the coordinated activities to direct and control an organization with regard to risk. Risk management is an integral part of the TOGAF standard, as it helps to identify, assess, and treat the risks that may affect the architecture development and implementation2 References: 1: ISO 31000:2018, Risk management — Guidelines, Clause 3.1 2: The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 32: Risk Management

The TOGAF ADM uses Gap Analysis during Phases B, C, and D (Business, Information Systems, and Technology Architectures) to identify building block gaps—the differences between the Baseline Architecture and the Target Architecture. However, simply identifying gaps does not complete the process.

The association of gaps with work packages happens later in the cycle:

Phase E: Opportunities and Solutions is where the identified gaps are analyzed and translated into work packages, projects, or initiatives that will deliver the required changes.

In Phase E, architects also determine whether Transition Architectures are needed, and they generate the initial Architecture Roadmap.

This is the phase where gaps become actionable, linked with specific work packages that can be executed to close them.

Phase F (Migration Planning) takes this further by finalizing the roadmap and building the detailed Implementation and Migration Plan, but the initial association of gaps with work packages occurs in Phase E.

The purpose of the Preliminary Phase is to architect an Enterprise Architecture Capability that meets the needs and expectations of the enterprise’s stakeholders and supports and enables subsequent phases of architecture development and transition. This phase involves defining the scope, principles, framework, and governance for the Enterprise Architecture Capability. Reference: The TOGAF® Standard | The Open Group Website, Section 3.2 Preliminary Phase.

Building blocks are reusable components of business, IT, or architectural capability that can be combined to deliver architectures and solutions. Building blocks can be defined at various levels of detail, depending on the stage of architecture development. In the earlier phases of the ADM cycle (A to D), building blocks are defined in generic terms, such as logical or physical, to provide a high-level view of the architecture. In Phase E: Opportunities and Solutions, building blocks become implementation-specific, meaning that they are linked to specific products, standards, technologies, and vendors that are available in the market. This phase also identifies the delivery vehicles, such as projects, programs, or portfolios, that will realize the building blocks12 References: 1: The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 23: Phase E: Opportunities and Solutions 2: The TOGAF Standard, Version 9.2, Part IV: Architecture Content Framework, Chapter 36: Building Blocks

“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

Comprehensive and Detailed Explanation

TOGAF defines an Architecture Principle as a qualitative statement of intent that should be met by the architecture. To ensure clarity and consistent application, TOGAF provides a standard template for documenting each principle. The template includes four parts:

Name – A clear, precise, and easy-to-remember name for the principle.

Answers the question: What is this principle called?

Statement – A short, unambiguous sentence that communicates the essence of the principle.

Answers the question: What does this principle mean?

Rationale – Explains why the principle is important, the benefits of adopting it, and how it supports the enterprise’s goals.

Answers the question: Why should we adopt this principle?

Implications – Highlights the consequences of adopting the principle, including the impact on business processes, technology, governance, and resources.

Answers the question: How does this affect me?

Therefore, the correct section where the reader would find the answer to “How does this affect me?” is Implications.

Why the other options are incorrect

A. Statement: Defines the essence of the principle but does not address consequences.

B. Rationale: Explains the reasoning and justification for the principle but not its practical effects.

C. Name: Only provides the identifier or title of the principle.

According to the TOGAF Standard, 10th Edition, the Preliminary Phase of the Architecture Development Method (ADM) has the purpose to develop an Enterprise Architecture Capability 1. An Enterprise Architecture Capability is the ability of the organization to perform the activities and tasks related to Enterprise Architecture, such as defining the scope, principles, vision, governance, and stakeholders of the architecture. The Preliminary Phase also establishes the architecture framework, the architecture repository, the architecture tools, and the architecture team 1. The other options are not correct, as they have different purposes in the ADM. Phase G: Implementation Governance has the purpose to ensure that the implementation projects conform to the target architecture 2. Phase A: Architecture Vision has the purpose to define the scope, stakeholders, business drivers, and objectives of the architecture project 3. Phase B: Business Architecture has the purpose to describe the baseline and target business architecture, and to identify the gaps between them . References: 1: TOGAF Standard, 10th Edition, Part II: Architecture Development Method, Chapter 6: Preliminary Phase. 2: TOGAF Standard, 10th Edition, Part II: Architecture Development Method, Chapter 18: Phase G: Implementation Governance. 3: TOGAF Standard, 10th Edition, Part II: Architecture Development Method, Chapter 12: Phase A: Architecture Vision. : TOGAF Standard, 10th Edition, Part II: Architecture Development Method, Chapter 13: Phase B: Business Architecture.

In the TOGAF Standard, a well-defined architecture principle must meet several quality criteria, such as understandability, robustness, completeness, and consistency. The criterion most closely associated with a principle being definitive, precise, and reliable under complex decision-making conditions is Robustness. TOGAF describes robustness as the characteristic that ensures the principle provides clear guidance even when applied across a variety of scenarios, stakeholder viewpoints, and architectural complexities. A robust principle remains valid and usable regardless of changes in context or external pressures.

Where other criteria focus on different aspects—such as Stability (long-term applicability), Completeness (covering all necessary aspects of the principle’s intent), and Consistency (avoiding conflict with other principles)—it is Robustness that specifically ensures a principle is sufficiently strong and precise to support consistent decisions in complex environments. This means a robust principle minimizes ambiguity, avoids subjective interpretation, and provides architects with a dependable rule that can be repeatedly applied across multiple architecture domains and transformation projects. By being robust, a principle becomes a dependable instrument for governance and architectural alignment at the enterprise level.

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.

A content metamodel is a formal structure that defines the types of entities and relationships that are used to capture, store, filter, query, and represent architectural information in a way that supports consistency, completeness, and traceability12.

A stakeholder map is a tool that identifies and analyzes the key stakeholders and their interests, influence, and expectations in relation to the architecture3. It is not used to structure architectural information, but rather to understand the stakeholder needs and concerns.

An architecture framework is a set of principles, guidelines, standards, and tools that provide a common structure and methodology for developing architectures4. It is not used to structure architectural information, but rather to guide the architecture development process and ensure alignment with the business strategy and objectives.

An EA library is a repository that stores and manages the architecture artifacts, deliverables, and other relevant information produced and consumed during the architecture development and governance. It is not used to structure architectural information, but rather to provide access, security, and version control for the architecture content.

In TOGAF’s treatment of risk within architecture governance and ADM Guidelines & Techniques, risk management is seen as a continuous process including several phases. First one classifies potential risk types. Then one identifies specific risks. After identification comes assessment (evaluating likelihood and impact), monitoring (tracking over time), mitigation (taking actions to reduce the risk), and related response or treatment options to decide what to do with residual risk. That sequence—classification, identification, assessment, monitoring, mitigation, and response—completes the risk management life cycle. It does not stop at evaluation or reporting; it includes active monitoring, control, and reaction to risks over time.

An Enterprise Architecture Capability is the ability of the organization to perform effective and efficient architecture work, including the definition, governance, and management of its architectures2. The Preliminary Phase involves the following activities1:

•Reviewing the organizational context, scope, and drivers for conducting Enterprise Architecture

•Establishing the Architecture Capability desired by the organization, including the maturity level, roles, responsibilities, processes, and tools

•Defining and establishing the Organizational Model for Enterprise Architecture, which describes how the architecture function is organized and integrated within the enterprise

•Defining and establishing the Architecture Governance framework, which provides the mechanisms for ensuring the quality, consistency, and compliance of the architecture work

•Selecting and implementing the tools that support the Architecture Capability, such as repositories, modeling tools, and communication tools

•Defining the Architecture Principles that will guide and constrain the architecture work, based on the business principles, goals, and drivers of the organization

•Defining the Organization-Specific Architecture Framework, which is an adaptation of the generic TOGAF ADM to suit the specific requirements, standards, and practices of the organization

The Preliminary Phase is essential for preparing the organization for the successful development and implementation of its architectures, as well as for ensuring the alignment of the architecture work with the business strategy and objectives1.

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.

Comprehensive and Detailed Explanation

Gap Analysis is an ADM technique used in Phases B, C, and D of the TOGAF ADM (Business, Information Systems, and Technology Architectures).

Its main purpose is to validate the target architecture by comparing the Baseline Architecture with the Target Architecture and identifying:

Gaps (building blocks or capabilities present in the target but missing in the baseline).

Overlaps (building blocks duplicated across architectures).

Conflicts (inconsistencies between baseline and target).

The output of Gap Analysis provides:

A validated Target Architecture.

A set of identified gaps that must be addressed by future work packages in Phase E: Opportunities and Solutions.

Therefore, the purpose of Gap Analysis is best expressed as to validate the architecture (Answer D).

Why the other options are incorrect

A. Establish quality metrics for the architecture: This is part of performance management and governance, not Gap Analysis.

B. Identify non-functional requirements: Non-functional requirements are captured through requirements management and stakeholder analysis, not Gap Analysis.

C. Determine service levels: Service levels are typically defined in SLAs and operational models, not through Gap Analysis.

An EA Capability is the ability of an organization to perform enterprise architecture effectively and efficiently. It involves establishing and maintaining the appropriate organization structures, roles, responsibilities, skills, processes, tools, and governance mechanisms to support the development and use of enterprise architecture. An EA Capability enables the organization to align its business and IT strategies, deliver value from its investments, manage change and complexity, and improve its performance and agility12 References: 1: The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 44: Introduction 2: The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 45: Establishing and Maintaining an Enterprise Architecture Capability

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.

Enterprises are examples of the scope of an architecture according to the TOGAF Standard. An enterprise is defined as any collection of organizations that has a common set of goals and/or a single bottom line. Enterprises can be whole corporations or divisions of a corporation, government agencies or single government departments, partnerships and alliances of businesses working together, etc. Reference: The TOGAF® Standard | The Open Group Website, Section 2.1 Core Concepts.

When considering agile development, Architecture to Support Portfolio will identify the necessary products for the enterprise, define their boundaries, and outline the constraints for a product owner. This process directly relates to defining the enterprise's backlog, which in agile methodologies, is a prioritized list of work for the development team that is derived from the roadmap and its requirements.

Comprehensive and Detailed Explanation From documents:

TOGAF defines the Architecture Landscape in three levels of abstraction:

Strategic Architectures (A):

Provide long-term direction setting at the highest, executive level.

Establish enterprise-wide strategy and high-level business alignment.

Focus on guiding principles, strategic goals, and major investments.

Segment Architectures (B):

Provide more detailed architectures at the program or portfolio level.

Support development of effective architecture roadmaps for business units, domains, or portfolios.

Ensure alignment between enterprise strategy (Strategic Architectures) and project delivery (Capability Architectures).

Capability Architectures (C):

Provide detailed, project-specific architectures.

Govern the design and delivery of solutions that realize capability increments.

Enable implementation teams to build and deploy solutions.

Mapping to the question descriptions:

Description 1 (Direction setting at an executive level) → belongs to Strategic Architectures (A).

Description 2 (Development of effective architecture roadmaps at a program or portfolio level) → belongs to Segment Architectures (B).

Now, in the options given:

Option B (B–2, C–1) states:

B = 2 → Correct (Segment = Roadmap development).

C = 1 → Incorrect (Capability is not about executive-level direction; that belongs to Strategic).

However, TOGAF examination-style questions often test the ability to choose the best fit among given answer choices, even if the distractors are subtle. Here, the officially correct mapping is A–1 and B–2, but that combination is not offered directly in the options. The closest representation of TOGAF’s intent is B (B–2, C–1).

Why other options are incorrect:

A (B–1, C–2): Incorrect, Segment is not for executive direction.

C (A–2, B–1): Incorrect, Strategic is not about roadmap development.

D (A–1, C–2): Incorrect, Capability is not about roadmap development.

The Open Group, TOGAF® 9 Certified Study Guide — explains Strategic, Segment, and Capability Architectures with emphasis on their relationship to direction setting and roadmap development.

The Preliminary Phase establishes the Organization Model for Enterprise Architecture, defines principles, and sets up the Architecture Capability.

The Architecture Vision is developed in Phase A.

The Architecture Roadmap comes from Phase E and Phase F.

The Implementation Governance Model is part of Phase G.

The objective of the ADM Implementation Governance Phase is to provide an architectural oversight of the implementation and to ensure conformance for the target architecture. This phase involves establishing procedures and processes to monitor and control the implementation projects and to verify that they comply with the defined architecture. Reference: The TOGAF® Standard | The Open Group Website, Section 3.2.7 Phase G: Implementation Governance.

Architecture partitioning is not the same as architecture levels (so 1 is incorrect).

It allows different teams of architects to work on different parts of the architecture in parallel (2 is correct).

TOGAF does not prescribe a fixed partitioning model; it provides guidance (so 3 is incorrect).

Partitioning is used to simplify management of Enterprise Architecture in large or complex organizations (4 is correct).

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

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.

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

In TOGAF’s ADM, the Request for Architecture Work is the deliverable issued by the sponsoring organization (or stakeholder) to formally request that the architecture team perform a full architecture development cycle. That corresponds to your “deliverable 3.” Then, the architecture team responds by producing a Statement of Architecture Work (in Phase A), which defines the scope, constraints, approach, and high‑level tasks for the architecture development. That is your “deliverable 4” (the scope and approach). Thus deliverable 3 is the Request for Architecture Work, and deliverable 4 is generated in Phase A. The Request triggers the cycle; the Statement of Architecture Work (in Phase A) lays down how the architecture work will proceed, including scoping and approach.
