Who this exam is for

The TOGAF 10 Foundation & Practitioner certification is designed for professionals who work with or want to work with The Open Group technologies in a professional capacity. It is taken by cloud engineers, DevOps practitioners, IT administrators, and technical professionals looking to validate their expertise.

You do not need extensive prior experience to attempt it, but you will benefit from hands-on familiarity with the subject matter. The exam tests applied knowledge and architectural judgment, not just memorization. If you can reason about trade-offs and real-world scenarios, structured practice will handle the rest.

Domain breakdown

The OG0-102 exam is built around official domains, each with a fixed percentage of the question pool. This distribution should directly inform how you allocate your study time.

Domain

Weight

Focus areas

Part 1 — Basic Concepts of Enterprise Architecture

20%

Enterprise architecture terminology, the purpose and scope of enterprise architecture, key stakeholders, and the benefits of a structured EA approach.

Part 1 — Core Concepts of TOGAF

30%

The TOGAF Standard structure, the Architecture Development Method overview, the Enterprise Continuum, Architecture Repository, and the TOGAF Content Framework.

Part 1 — ADM Introduction and Application

25%

The ADM cycle phases (Preliminary, A through H, Requirements Management), each phase's objectives, inputs, steps, and outputs.

Part 1 — Enterprise Continuum and Tools

25%

The Architecture Continuum and Solution Continuum, the Architecture Repository structure, Architecture Building Blocks vs. Solution Building Blocks, and reference models (TRM, III-RM).

Part 2 — Applied ADM Scenarios

Separate pass mark

Complex scenario questions requiring you to apply ADM phases, select appropriate deliverables, evaluate stakeholder concerns, and make governance decisions using the open-book TOGAF Standard.

Note the domain with the highest weight — many candidates under-invest here because it feels conceptual. In practice, this is where the exam is most precise, with scenario-based questions that test specifics.

What the exam actually tests

This is not a memorization exam. Questions require applied judgment under constraints. Almost every question includes a scenario with explicit requirements and asks you to select the most appropriate solution.

Here are examples of the question types you will encounter:

Part 1 — Definition and Recall

"Which ADM phase is responsible for defining the Target Business Architecture and identifying the gaps from the Baseline?"

Part 1 tests precise knowledge of ADM phase names, their sequence, and their primary outputs. Create a one-row-per-phase ADM reference table with objective, key inputs, and key outputs before exam day.

Part 1 — Concept Mapping

"An Architecture Building Block represents a package of functionality. At which level of the Architecture Continuum does it reside?"

Maps TOGAF artefacts and concepts to their position in the Enterprise Continuum or Architecture Repository. Draw the Enterprise Continuum diagram from memory and label every component.

Part 2 — Scenario Application (Open Book)

"A large government agency is completing Phase B. The business sponsor raises a concern about regulatory compliance in the Target Architecture. According to TOGAF, what should the architect do FIRST?"

Part 2 gives you the TOGAF Standard to reference but tests complex scenario judgment. Practise answering Part 2 questions against a time limit — 8 questions in 90 minutes allows over 11 minutes per question, but scenario reading takes time.

How to prepare — 4-week study plan

This plan assumes one hour per weekday and roughly 30 minutes of lighter review on weekends. It is calibrated for someone with some relevant experience. If you are starting from zero, add an extra week before Week 1 to familiarise yourself with the basics.

Week 1: TOGAF Core Concepts & ADM Phase Overview

Read the TOGAF Standard Part 1 and Part 2 overview chapters: understand the overall structure, the purpose of the ADM, and the relationship between architecture domains (Business, Data, Application, Technology).
Create an ADM phase reference table: for each phase (Preliminary, A–H, Requirements Management), record the phase objective in one sentence and the three most important outputs.
Study the Enterprise Continuum: Architecture Continuum (Foundation — Common Systems — Industry-Specific — Organisation-Specific) and Solution Continuum with its parallel structure.
Complete a 30-question ADM basics quiz; focus on phase sequence, phase names, and phase transitions.

Week 2: Architecture Repository, Content Framework & Building Blocks

Study the Architecture Repository in depth: six components (Architecture Metamodel, Architecture Landscape, Standards Library, Reference Library, Governance Log, Architecture Requirements Repository).
Learn the TOGAF Content Framework: architecture artifacts (catalogs, matrices, diagrams), architecture building blocks, and the distinction between ABBs and SBBs.
Study the TOGAF Reference Models: Technical Reference Model (TRM) with its Application Platform and the Integrated Information Infrastructure Reference Model (III-RM).
Complete a 25-question content framework and building blocks drill; map every wrong answer to the correct TOGAF Standard chapter.

Week 3: ADM Deep Dive, Governance & Open-Book Technique

Study Architecture Governance: the Architecture Board, compliance reviews, Architecture Contracts, and the distinction between Architecture Governance and IT Governance.
Cover Stakeholder Management: the stakeholder map, concern identification, viewpoints and views, and how to tailor architecture descriptions for different audiences.
Practise the open-book technique for Part 2: tab or bookmark the TOGAF Standard by phase, mark the Architecture Governance section, and practise the scenario-reading approach used in PRINCE2 Practitioner.
Sit a full Part 1 (40 questions, 60 minutes) mock exam; record your score per domain and flag any area below 55%.

Week 4: Part 2 Scenario Mastery & Final Mock Exams

Complete all available Part 2 (8-question scenario) mock papers under timed open-book conditions; read the TOGAF Standard section before attempting each question set.
Re-drill Part 1 weak areas: focus especially on Architecture Continuum positioning and ADM phase output identification.
Sit a complete combined mock (Part 1 + Part 2 back to back, 2.5 hours total) to simulate exam-day endurance.
On exam day, complete Part 1 within 55 minutes to leave 5 minutes for review, then use the full 90 minutes for Part 2 — never rush the scenario questions.

Common mistakes candidates make

These patterns appear repeatedly among candidates who resit this exam. Knowing them in advance is worth several percentage points.

Confusing the Architecture Continuum with the Solution Continuum

The Architecture Continuum describes increasingly specific architecture descriptions (Foundation → Common Systems → Industry → Organisation), while the Solution Continuum describes corresponding implemented products and services. They are parallel but distinct. Exam questions frequently ask which continuum a specific artefact or activity belongs to.

Treating Part 2 as an extension of Part 1

Part 2 does not just test more TOGAF knowledge — it tests your ability to reason through complex architectural decisions in context. Candidates who approach Part 2 questions by scanning for TOGAF terms rather than understanding the scenario's business problem tend to select technically correct but contextually wrong answers. Practice reading scenarios for stakeholder intent before looking at options.

Misidentifying ADM phase outputs

Many wrong answers result from attributing a deliverable to the adjacent phase. For example, the Architecture Vision is produced in Phase A, not the Preliminary Phase. The Architecture Roadmap is developed iteratively from Phase E. Create a strict phase-to-output mapping table and test yourself until every assignment is automatic.

Under-using the open book in Part 2

Unlike PRINCE2 Practitioner where over-reliance on the open book wastes time, TOGAF Part 2 gives 90 minutes for only 8 questions — over 11 minutes each. For any question where you are less than 80% confident, locate the relevant ADM phase section in the TOGAF Standard and verify your answer before selecting it. The open book is a genuine advantage at this pace.
