OGEA-103 TOGAF Enterprise Architecture Combined Exam: Preparing for Foundation and Practitioner Together

OGEA-103 is the current TOGAF Enterprise Architecture Combined Part 1 and Part 2 examination from The Open Group. It provides a direct route to the TOGAF Enterprise Architecture Practitioner qualification for candidates who want to take both levels in one appointment. The examination contains 48 questions across two sections and allows 150 minutes in total: 40 Foundation-style questions in Part 1 with a 60-minute limit, followed by eight scenario-based Practitioner questions in Part 2 with a 90-minute limit.

The two sections are assessed separately. Part 1 requires at least 60%, and Part 2 also requires at least 60% of its gradient-scored points. Passing one section while failing the other does not award the combined qualification, but The Open Group’s current policy allows the candidate to retain the passed result and retake only the failed standalone part after the required waiting period. That structure makes OGEA-103 convenient, but it does not turn Foundation recall and Practitioner analysis into one undifferentiated study task.

The combined route compresses scheduling, not learning

OGEA-103 is often attractive because a candidate can target Practitioner certification through a single booked examination rather than scheduling OGEA-101 and OGEA-102 separately. The efficiency is administrative. The knowledge still spans two cognitive levels: Part 1 checks understanding of concepts, the ADM, techniques, governance, application, and architecture content, while Part 2 asks the candidate to apply and analyze the standard in realistic situations.

A good plan therefore creates two preparation tracks that converge late. Build Foundation precision first so terminology and phase purposes are automatic. In parallel, begin scenario work once the vocabulary is stable. Near the exam, combine the tracks into full sessions that reproduce the change in pace between sections. Trying to prepare only with mixed question banks can hide a weakness because familiarity with scenarios does not guarantee clean Foundation recall, and strong recall does not guarantee Practitioner judgment.

Part 1 rewards organized understanding under a steady pace

The first section uses forty simple multiple-choice questions and a sixty-minute limit. Candidates should be comfortable with core concepts, the structure and purpose of the ADM, introductory ADM techniques, application and tailoring, architecture governance, and architecture content. The average pace is manageable, but indecision over basic distinctions can create unnecessary time pressure before the more demanding second section.

Use the current Part 1 blueprint to allocate revision proportionally. The ADM is the largest area, but smaller domains cannot be ignored. Create compact explanations of stakeholder, concern, view, viewpoint, architecture principles, building blocks, deliverables, artifacts, governance, requirements, baseline and target architecture, and the purpose of each ADM phase. The objective is not a memorized glossary; every term should connect to how architecture work is organized.

Because the combined exam moves directly into Part 2, train yourself to close the Foundation section mentally once it is finished. Replaying uncertain questions wastes attention you will need for scenarios, and the exam does not allow the candidate to return to Part 1 after moving forward.

Part 2 requires ranking plausible actions rather than spotting one obvious fact

The Practitioner section contains eight scenario-based questions with gradient scoring. The best response receives five points, with lower partial credit for less suitable alternatives. This format expects the candidate to interpret context: which stakeholders matter, what phase or architecture concern is active, what requirements constrain the choice, and which action best aligns the method to the situation.

Practice by ranking all response options before reading the explanation. State why the strongest answer is superior and why the nearest alternative is incomplete. This turns partial-credit scoring into a study advantage because it encourages comparative reasoning. If an answer contains a valid TOGAF activity but performs it at the wrong time, ignores stakeholder concerns, or skips required governance, that weakness should be visible.

Part 2 provides its relevant body of knowledge as an integrated open-book reference. Use it to confirm details after identifying the governing concept, not as a replacement for knowing where to look. The strongest candidates enter a scenario with a mental map of the method and use the reference selectively.

The ADM must remain coherent across both levels

The Architecture Development Method is the thread joining the two sections. Part 1 asks what phases and concepts mean; Part 2 asks how to use them. For every ADM phase, prepare at three levels: purpose, typical decisions, and scenario signals. For example, recognizing Phase A is one skill; noticing that a case still lacks agreed scope, stakeholders, or Architecture Vision is the applied version of that skill.

Requirements Management deserves the same treatment. It is easy to recite that requirements interact with the ADM, but Practitioner questions can ask what to do when a requirement changes, conflicts with architecture direction, or emerges from later analysis. Connect the definition to impact assessment, traceability, stakeholder decisions, and governance. That is the kind of bridge from knowledge to practice that the combined exam is designed to expose.

Tailoring and iteration also prevent mechanical phase-order answers. TOGAF provides a method, not a claim that every architecture engagement has identical scope and depth. The candidate should recognize disciplined adaptation without choosing options that bypass necessary architecture work.

Architecture Content should support decisions rather than become document memorization

Foundation questions may ask candidates to distinguish deliverables, artifacts, and building blocks. Practitioner scenarios can then require judgment about what information or architecture output is needed. Study the content model as a way to structure architecture knowledge: catalogs organize lists, matrices expose relationships, diagrams communicate views, and formal deliverables package material for review and use.

A useful exercise is to take a simple transformation and identify the minimum architecture information needed to support a decision. Which stakeholders need which views? Which relationships must be made visible? What needs formal approval? What can be reused from an architecture repository? This turns content terminology into a decision-support system rather than a list of document names.

Governance and stakeholder work become more important as the scenarios become realistic

Enterprise Architecture succeeds only when decisions have owners, stakeholders understand implications, and implementation is governed against architecture direction. Part 2 scenarios often become difficult because more than one answer is technically possible, but only one respects stakeholder concerns, approval authority, or the need to assess conformance before acting.

Practice identifying the stakeholder whose concern actually drives the question. An executive sponsor, security team, operations group, delivery team, regulator, and business owner may all be present, yet the required architecture action can differ depending on whose concern must be addressed at that point. Good scenario reasoning avoids the false choice between “communicate” and “do architecture”; stakeholder engagement is part of doing architecture well.

The combined exam has a specific recovery path if one section fails

The Open Group’s current rules are more nuanced than simply “fail the whole exam.” OGEA-103 awards the Practitioner qualification only when both sections are passed, and passing Part 1 alone inside the combined exam does not separately award Foundation certification. However, a passed section is retained. After the required one-month waiting period, the candidate needs to retake only the corresponding standalone exam for the failed section.

That means a Part 1 failure is recovered through OGEA-101, while a Part 2 failure is recovered through OGEA-102. Once the missing pass result is received, the results are combined for the qualification. Candidates should know this before booking because it affects risk and scheduling decisions. Someone who wants a Foundation credential awarded as soon as possible may prefer the staged route even if the total subject matter is the same.

OGEA-103 is not the only path to the current Practitioner qualification

The current certification portfolio supports multiple routes. Foundation holders can take Part 2. New candidates can take Part 1 and then Part 2, or the combined exam. People who already hold TOGAF 9 Certified can use the bridge route through OGEA-10B. Choosing among them should depend on existing credentials, desired milestones, and exam-day preferences rather than an assumption that one path is intrinsically more prestigious.

Candidates should also be cautious with study material that calls the current qualification “TOGAF 10 Certified.” The Open Group intentionally names it TOGAF Enterprise Architecture Practitioner and decouples certification naming from a simple version-number label. Using current terminology helps keep training, booking, and credential expectations aligned.

The combined route also rewards deliberate mental reset. Part 1 is dense with definitions and relationships; Part 2 slows the pace and demands richer comparison. During full mocks, create a brief transition routine: finish the first section, release the unanswered doubt you can no longer change, reset your reading pace, and approach the first scenario as a new task. This sounds minor, but it prevents the fast-response rhythm of Foundation questions from carrying into cases that require slower interpretation.

A combined mock session is the best final readiness test

Late in preparation, reproduce the full 150-minute structure. Use a timed Foundation block, stop when it ends, and immediately begin a timed Practitioner block. This tests more than knowledge. It reveals whether pace, concentration, reference use, and decision quality remain stable after the first hour. Review the two sections separately afterward so one strong result cannot hide a weak one.

For Foundation errors, identify the missing concept or relationship and repair it with concise notes. For Practitioner errors, record the scenario clue that changed the ranking of answers. Then repeat only targeted drills before the next full simulation. This is more efficient than endlessly taking complete mocks without diagnosing why points are being lost.

OGEA-103 preparation should reproduce the combined structure rather than mixing unrelated questions: time a Foundation block, transition directly into scenario analysis, then review each section independently. Keep the official body of knowledge and current exam rules as the boundary so practice strengthens understanding and reasoning instead of replacing them with memorized question patterns.
