OGEA-101 Exam Syllabus & Core Topics

Use this topic map to guide your study for The Open Group OGEA-101 (TOGAF Enterprise Architecture Part 1 Exam) within the TOGAF Certifications path.

  • Introduction to Enterprise Architecture: Understand the definition, purpose, and business drivers behind enterprise architecture. You should be able to explain why organizations adopt EA and how it aligns business and technology strategy.
  • Core Concepts of the TOGAF Standard: Recognize key TOGAF terminology, principles, and the overall structure of the standard. This includes knowing the relationships between architecture domains and how TOGAF components interact.
  • Architecture Development Method (ADM): Master the nine ADM phases and their sequencing. You must be able to identify which phase addresses specific architecture challenges and describe the deliverables and activities within each phase.
  • Enterprise Continuum and Tools: Learn how the Enterprise Continuum organizes architecture assets and how tools support architecture development. Recognize the difference between generic and organization-specific architectures.
  • Architecture Governance: Understand governance structures, compliance frameworks, and decision-making processes in architecture practice. You should identify governance roles and explain how they enforce architecture standards.
  • TOGAF Reference Models: Know the purpose and application of TOGAF reference models, including the Technical Reference Model (TRM) and the Integrated Information Infrastructure Reference Model (III-RM). Understand how these models guide architecture design.

Question Formats & What They Test

The OGEA-101 exam uses multiple-choice questions to assess both conceptual knowledge and practical reasoning in enterprise architecture contexts. Questions progress in difficulty and require you to apply TOGAF principles to realistic scenarios.

  • Knowledge-based items: Recall definitions, TOGAF phases, governance roles, and reference model components. These test your familiarity with standard terminology and structural concepts.
  • Scenario-based items: Analyze business situations and select the most appropriate ADM phase, governance approach, or architecture decision. For example, you may need to identify which phase best addresses a stakeholder requirement or determine the right architecture governance model for a given organizational context.
  • Application-focused items: Connect multiple TOGAF concepts across planning, execution, and review workflows. You may be asked how the Enterprise Continuum supports architecture reuse or how architecture governance ensures compliance across ADM phases.

Questions increase in complexity as you progress, rewarding both memorization and the ability to reason through architecture decisions in realistic conditions.

Preparation Guidance

An effective study plan breaks the syllabus into weekly goals, allowing you to build knowledge systematically while reinforcing connections between topics. Dedicate time to both concept review and scenario practice to develop the reasoning skills the exam tests.

  • Map the six core topics (Introduction to Enterprise Architecture, Core Concepts of the TOGAF Standard, Architecture Development Method, Enterprise Continuum and Tools, Architecture Governance, and TOGAF Reference Models) to a 4-6 week study schedule. Allocate more time to ADM and governance, which typically carry greater exam weight.
  • Work through practice question sets regularly. After each attempt, review explanations for both correct and incorrect answers to understand the reasoning behind each option.
  • Link concepts across topics: for example, understand how ADM phases interact with governance frameworks and how the Enterprise Continuum informs architecture decisions.
  • Complete a timed practice test under exam conditions in your final week. This builds pacing confidence and reveals any remaining gaps.
  • Review weak areas one more time, focusing on scenario-based questions that require application of multiple concepts.

Frequently Asked Questions

What topics carry the most weight on the OGEA-101 exam?

The Architecture Development Method (ADM) and Architecture Governance typically account for a larger portion of exam questions. These topics require both conceptual understanding and the ability to apply TOGAF principles to real-world scenarios. While all six core topics are tested, prioritizing deeper study of ADM phases and governance frameworks will strengthen your overall score.

How do the six core topics connect in actual enterprise architecture projects?

In practice, these topics form an integrated workflow. Introduction to Enterprise Architecture and Core Concepts establish the foundation. The ADM provides the structured process for developing architectures. The Enterprise Continuum and Tools support reuse and asset management. Architecture Governance ensures compliance and oversight throughout the ADM cycle. TOGAF Reference Models guide technical design decisions. Understanding these connections helps you see TOGAF as a cohesive system rather than isolated concepts.

What hands-on experience helps most when preparing for OGEA-101?

Direct experience with architecture projects is valuable but not required for this foundational exam. If available, familiarity with business process mapping, stakeholder analysis, and technology planning provides useful context. More important is working through scenario-based practice questions that simulate real architecture challenges, as these build the reasoning skills the exam tests.

What mistakes commonly cost points on this exam?

Candidates often confuse ADM phases or misidentify which phase addresses a specific architecture challenge. Another common error is selecting governance approaches without considering organizational context. Additionally, some test-takers rush through questions without fully reading scenario details, missing important context clues. Careful reading and understanding the "why" behind each answer choice, rather than memorizing facts, helps avoid these pitfalls.

How should I approach the final week before the exam?

In your final week, shift focus from new content to review and pacing practice. Take one full-length timed practice test to identify any remaining weak areas. Spend 2-3 days reviewing those specific topics with explanations and scenario questions. In the last 2-3 days, do lighter review of high-weight topics (ADM and Governance) and practice managing your time across different question types. Avoid cramming new material, which increases test anxiety without building lasting understanding.

Question No. 1

Which of the following best describes the TOGAF Architecture Development Method?

Show Answer Hide Answer
Correct Answer: D

The TOGAF Architecture Development Method (ADM) is best described as a repeatable process for developing architectures. It provides the step-by-step method used to create, evolve, govern, and manage enterprise architectures in a consistent and structured way. The ADM is the core of TOGAF and defines how architecture work progresses from preparation and vision through business, data, application, and technology architecture, then into opportunities, migration planning, implementation governance, and change management.

Option A is incorrect because a classification mechanism is not the purpose of the ADM. Option B is too narrow, since requirements management is only one supporting aspect of the ADM, not its full definition. Option C is also incorrect because readiness assessment may be used as a technique within architecture practice, but it is not what the ADM itself is.

The strength of the ADM is that it is iterative, adaptable, and repeatable. It can be tailored for different enterprises and change scenarios while still preserving a consistent method. This makes it suitable for both large transformation efforts and more focused architecture initiatives. Therefore, the best description is option D, a repeatable process for developing architectures.


Question No. 2

What does the TOGAF ADM recommend for use in developing an Architecture Vision document?

Show Answer Hide Answer
Correct Answer: D

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. Reference:

Question No. 3

Consider the illustration.

What are the items labelled A B and C?

Show Answer Hide Answer
Correct Answer: D

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


Question No. 4

In the ADM, what is the name for a document deliverable that has completed a review and is approved?

Show Answer Hide Answer
Correct Answer: A

Comprehensive and Detailed Explanation

In the TOGAF ADM, deliverables go through a lifecycle of development, review, approval, and usage. TOGAF distinguishes between draft deliverables (work-in-progress) and final deliverables (those that have been formally reviewed and signed off).

* Draft deliverables are produced as working versions of the required outputs in each ADM phase. These may carry version labels such as 0.1, 0.5, 0.9, etc., and are subject to stakeholder review and refinement.

* Once the document has been reviewed and approved by the relevant stakeholders (e.g., Architecture Board, governance bodies), it becomes a final deliverable.

* Final deliverables are baseline-controlled items and are formally stored in the Architecture Repository as an approved architecture artifact.

Thus, the correct term for a deliverable that has completed review and is approved is ''final''.

Why the other options are incorrect

* B. Approved: While true in general language, TOGAF uses the formal term ''final deliverable'', not ''approved deliverable.''

* C. Ratified: This term is not used in TOGAF to describe the state of a deliverable.

* D. Version 0.9: This is a draft numbering convention, not the status of an approved deliverable.

* The Open Group, TOGAF 9 Certified Study Guide --- explanation of draft vs. final deliverables in the ADM lifecycle.


Question No. 5

Which of the following is a purpose of creating a set of Architecture Principles?

Show Answer Hide Answer
Correct Answer: B

''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.''
