TOGAF® EA Practitioner — Mock Exam Studio

🌐 Live demo: https://csahli.github.io/TOGAF_EA_10_Prep/

A single-page web app for practising TOGAF Standard 10th Edition exam questions, aligned to the published OGEA-101 / OGEA-102 / OGEA-103 exam structure.

Features

• Level 1 (Foundation) — 128 single-best-answer recall questions, each with a best-effort citation back to the TOGAF Standard 10th Edition (C220) or the relevant TOGAF Series Guide. 128 unique stems across 25 topics.
• Level 2 (Practitioner) — 128 scenario questions scored on the same 5/3/1/0 gradient the OGEA-102 exam uses (best = 5, second-best = 3, third-best = 1, distractor = 0). The gradings themselves are the author's interpretation, not an Open Group answer key. Built from 16 distinct scenario templates × company-name variants — within any single session, picks are deduplicated so the same scenario never repeats under a different company name.
• Blended — mixes both levels in one practice session.
• Practice mode — pick your own question count, shuffle and toggle instant feedback per question. When you answer a question the rationale and the C220 reference appear inline immediately.
• Official exam simulation — enforces the published Open Group conditions:
  • OGEA-101: 40 questions / 60 minutes / closed book / 24-40 pass
  • OGEA-102: 8 questions / 90 minutes / open book / 24-40 pass
  • OGEA-103 Combined: 48 questions / 150 minutes / each part 24-40 to pass
  • Visible countdown timer, auto-submit on timeout
  • The full set of questions is chosen up-front at the start of the simulation (no on-the-fly resampling) and Level 2 picks are guaranteed to come from distinct scenario templates.
• Score ring, per-question review with rationales and source citations on both the inline feedback and the final review screen
• Glossary of 30 core TOGAF concepts with links to the official TOGAF Standard, plus 10 inline reference diagrams (ADM Cycle, TOGAF Enterprise Metamodel, Content Framework, Architecture Repository, Enterprise Continuum, ABB→SBB, ADM Iteration Cycles, Architecture Landscape levels, Stakeholder Power/Interest matrix, Architecture Partitioning) — click any diagram to enlarge
• Score history stored in your browser (localStorage) — plus Export to JSON

Run it

Just double-click index.html (or open it in any browser). No server required.

The question banks are loaded as plain JavaScript files (data/questions_level1.js / data/questions_level2.js) via <script> tags, so everything runs straight from file://. Keep the data/ folder next to index.html.

Accuracy and verification

This tool is provided as a free study aid on a best-effort basis. It is not authoritative and is not a substitute for the official TOGAF Standard, a reputable study guide, or accredited training.

The questions and rationales were drafted with reference to the TOGAF Standard 10th Edition evaluation bundle (C220 Parts 0-5) and then run through a self-review pass to catch obvious errors, miscitations, and TOGAF 10 → TOGAF 9 naming drift. A handful of corrections were applied as a result (e.g. Architecture Development iteration, TOGAF Enterprise Metamodel, Implementation Factor Catalog). The per-question Reference: line on the review screen points at the C220 section the item was drafted from, so you can always verify a claim against the source yourself — and you should, especially before relying on any item for exam preparation.

Known limitations:

• The review pass was best-effort, not exhaustive; remaining inaccuracies, ambiguous phrasing, or outdated terminology are likely.
• "Best", "second-best", "third-best" and "distractor" gradings on Level 2 scenarios reflect the author's interpretation of TOGAF guidance, not an Open Group answer key. Real OGEA-102 grading may differ on borderline options.
• The L2 question pool is built from 16 distinct scenario templates combined with org-name variants. Within any one session the app enforces template-distinct picks, so you won't see the same scenario twice in a row — but across many sessions you will eventually see every template. Coverage is narrower than the headline "128 L2 questions" suggests; treat repeated exposure as familiarity practice, not as evidence of mastery.
• Citation accuracy is the author's best read of where each concept lives in the standard; chapter and section numbers may be off by one in places.

If you spot an error, please open an issue or a pull request — corrections are welcome.

For authoritative practice and assessment, use The Open Group's own materials, an accredited training provider's study pack, or the published TOGAF® Series Guides and the TOGAF Standard itself.

Regenerate / extend the question banks

Edit the templates in generate_questions.py, then:

python generate_questions.py

This rewrites both JSON files and both JS files (128 questions each).

Edit or add diagrams

Each reference diagram lives as its own .svg file in data/diagrams/, with metadata (title, description, topic) in data/diagrams/descriptions.json. After editing either, rebuild the runtime bundle:

python build_diagrams.py

See data/diagrams/README.md for the file conventions and how to add a new diagram.
