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

The image shows a diagram that illustrates the basic concepts of architecture description as defined by the ISO/IEC/IEEE 42010:2011 standard1, which is also adopted by the TOGAF standard2.

According to the ISO/IEC/IEEE 42010:2011 standard, an architecture description is a work product used to express an architecture, and it consists of one or more architecture views1.

An architecture view is a representation of a system from the perspective of a related set of concerns, and it conforms to an architecture viewpoint1.

An architecture viewpoint is a specification of the conventions for constructing and using an architecture view to address specific stakeholder concerns1.

Therefore, the correct answer is option A, which identifies the items labeled as “A” and “B” in the image as an architecture viewpoint and an architecture view, respectively. References:

1: ISO/IEC/IEEE 42010:2011 - Systems and software engineering — Architecture description1

2: TOGAF Standard, Version 9.2 - Part IV: Architecture Content Framework - 31. Architectural Artifacts2

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.

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 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.

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.

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 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.

The class of information known as the Reference Library within the Architecture Repository contains guidelines and templates used to create new architectures. The Reference Library provides a set of resources that can be leveraged or customized for specific architecture development purposes. It includes generic building blocks, patterns, models, standards, frameworks, methods, techniques, best practices, etc. Reference: The TOGAF® Standard | The Open Group Website, Section 2.4 Architecture Repository.

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 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.

The Architecture Landscape is divided into levels known as Segment Strategic and Capability Architectures. These levels correspond to different scopes and purposes of architectures within an enterprise. Segment Architectures are architectures that address specific business units, functions, or processes within an enterprise. Strategic Architectures are architectures that provide a high-level view of the enterprise’s vision, goals, and direction. Capability Architectures are architectures that address specific business capabilities or services that span multiple segments or domains. Reference: The TOGAF® Standard | The Open Group Website, Section 2.4 Architecture Repository.

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:

Business Transformation Readiness Assessment is a joint effort between corporate staff lines of business and IT planners to evaluate the readiness of the organization to undergo change. It involves assessing factors such as vision, commitment, capacity, capability, culture, and motivation that may influence the success of a business transformation initiative. Reference: The TOGAF® Standard | The Open Group Website, Section 3.3.2 Business Transformation Readiness Assessment.

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.

Phase E: Opportunities & Solutions – Steps/Outputs emphasize grouping work packages, dependencies, and planning the roadmap/plan that reflect value/effort:

“Identify and group major work packages… Refine and validate dependencies… Create the Architecture Roadmap & Implementation and Migration Plan.” www.opengroup.org

Phase B of the ADM cycle is the Business Architecture phase. It describes the development of a Business Architecture to support an agreed Architecture Vision. The objectives of this phase are to describe the baseline and target Business Architecture, identify candidate Architecture Roadmap components based on gaps between the baseline and target, and determine whether an incremental approach is required. Reference: The TOGAF® Standard | The Open Group Website, Section 3.2.2 Phase B: Business Architecture.

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.

Business principles business goals, and business drivers provide context for architecture work, by describing the needs and ways of working employed by the enterprise. They define what the enterprise wants to achieve, how it wants to operate, and what factors influence its decisions and actions. Reference: The TOGAF® Standard | The Open Group Website, Section 3.2 Preliminary Phase.

The statement "Projects may cycle between ADM phases, in planned cycles covering multiple phases" illustrates the concept of iteration, which is the process of repeating the ADM phases or steps within a phase to refine the architecture outputs and address the changing requirements and stakeholder concerns. Iteration can occur at different levels of granularity and scope, such as within a single phase, across multiple phases, or across the entire ADM cycle. Iteration can also be applied to different architecture domains, such as business, data, application, and technology. Iteration is a key feature of the ADM that enables the development of architectures that are fit for purpose, adaptable, and responsive to change. References: : The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 24: Applying Iteration to the ADM

The TOGAF Content Framework defines a detailed model of architectural work products (artifacts, deliverables, building blocks) and the relationships between them.

It is not a lifecycle management capability (A), that is related to the ADM itself.

It is not organized strictly by ADM phases (B).

It is not fixed; it is designed to be tailored (C).

“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

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

Comprehensive and Detailed Explanation

In TOGAF, Architecture Contracts are agreements between development partners and sponsors that define:

The deliverables to be produced.

The quality expectations.

The fitness-for-purpose of the architecture.

The responsibilities of each party and the governance arrangements.

Architecture Contracts are a key part of Phase G: Implementation Governance, where they are used to manage and control architecture implementation. They help ensure that implementation projects remain aligned with the approved Target Architecture and business objectives.

They serve as the formal mechanism for:

Validating that architecture deliverables meet stakeholder expectations.

Providing a measurable basis for conformance assessment.

Supporting architecture governance by linking architectural intent with project execution.

Why the other options are incorrect

B. The Statement of Architecture Work: This defines the scope, approach, resources, and schedule for architecture work, but it is not a joint agreement on deliverables and fitness-for-purpose.

C. Service Level Agreements (SLAs): These are agreements about operational service levels (e.g., availability, performance), not architecture deliverables.

D. Non-disclosure Agreement (NDA): This protects confidentiality of information but does not address deliverables, quality, or fitness-for-purpose of an architecture.

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.

Phase A: Architecture Vision is the first phase of the Architecture Development Method (ADM) cycle, which is the core of the TOGAF standard. The main purpose of this phase is to define the scope and approach of the architecture development, and to create the Architecture Vision, which is a high-level description of the desired outcomes and benefits of the proposed architecture. To achieve this purpose, this phase focuses on defining the problem to be solved, identifying the stakeholders, their concerns, and requirements, and establishing the business goals and drivers that motivate the architecture work. This phase also involves obtaining the approval and commitment of the sponsors and other key stakeholders, and initiating the Architecture Governance process.

The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 5: Introduction to the ADM : The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 18: Phase A: Architecture Vision : The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 18.3: Inputs : The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 18.4: Steps

These domains provide a consistent way to describe and understand the architecture from different perspectives, such as business, information, and technology12. Each domain has its own set of concepts, models, views, and artifacts that define the structure and behavior of the architecture within that domain12.

The other options are incorrect because:

•Logical and Physical are not architecture domains, but rather levels of abstraction that can be applied to any domain. Logical architecture describes the functionality and behavior of the system, while physical architecture describes the implementation and deployment of the system3.

•Information and Data are not distinct architecture domains, but rather aspects of the same domain. Information architecture describes the meaning and context of the data, while data architecture describes the structure and format of the data4.

•Capability and Segment are not architecture domains, but rather levels of granularity that can be applied to any domain. Capability architecture describes the current and desired states of a specific business capability, while segment architecture describes a subdivision of the enterprise that has a clear business focus5.

Business scenarios are a technique recommended by the TOGAF ADM for use in developing an Architecture Vision document12. Business scenarios are a means of capturing the business requirements and drivers, the processes and actors involved, and the desired outcomes and measures of success34. Business scenarios help to create a common vision and understanding among the stakeholders, and to identify and validate the architecture requirements . Business scenarios also provide a basis for analyzing the impact and value of the proposed architecture. References:

“TOGAF defines **‘enterprise’ as any collection of organizations that has a common set of goals. For example, an enterprise could be a government agency, a whole corporation, a division of a corporation, a single department, or a chain of geographically distant organizations linked together by common ownership.” www.opengroup.org

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, 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

Phase A: Architecture Vision identifies stakeholders, their concerns, and defines the scope and objectives of the architecture engagement.

Defining enterprise strategy is outside ADM (it is a business planning activity).

Describing the target architecture happens in Phases B, C, and D.

Developing an EA Capability is done in the Preliminary Phase, not Phase A.

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. Reference: The TOGAF® Standard | The Open Group Website, Section 3.1 Introduction to the ADM.

A business scenario describes business and technology environment in which those problems occur. It provides a realistic context for identifying and addressing business problems and opportunities, as well as their impact on the enterprise’s architecture. Reference: The TOGAF® Standard | The Open Group Website, Section 3.3.1 Business Scenarios.

business and technology environment in which those problems occur https://pubs.opengroup.org/togaf-standard/business-architecture/business-scenarios.html#_Toc68617078 "

A Business Scenario is a uniform description of: - Real business problems - The business and technology environment in which those problems occur - Value streams enabled by capabilities - The desired outcome(s) of proper execution - The human and computing components (the “actors”) who provide the capabilities"

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.

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

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

The Enterprise Continuum provides methods for classifying architecture artifacts as they evolve from generic architectures to Organization-Specific Architectures. Generic architectures are architectures that have been developed for use across a wide range of enterprises with similar characteristics. They provide common models, functions, and services that can be reused and adapted for specific purposes. Organization-Specific Architectures are architectures that have been tailored to meet the needs and requirements of a particular enterprise or a major organizational unit within an enterprise. They reflect the unique vision, goals, culture, structure, processes, systems, and technologies of that enterprise or unit. Reference: The TOGAF® Standard | The Open Group Website, Section 2.3 Enterprise Continuum.

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
