What This Course Is
This course covers the Claude Certified Architect – Professional exam in the same format as the Foundations course: one lesson per Anthropic module, each containing the complete frameworks, decision tables, and rules the exam tests directly.
Exam snapshot:
- 5 modules, 7 domains
- 63 questions (11 + 8 + 12 + 10 + 9 + 9 + 4 across domains)
- 120 minutes
- Target: 75%+ per domain
Domain weights:
| Domain | Weight |
|---|---|
| Integration | 19% |
| Solution Design & Architecture | 17% |
| Evaluation, Testing & Optimization | 16% |
| Governance, Safety & Risk | 14% |
| Stakeholder Communication & Lifecycle | 14% |
| Claude Models, Prompting & Context Engineering | 13% |
| Developer Productivity & Ops | 7% |
Professional vs Foundations
Foundations asks: can you identify the correct mechanism?
Professional asks: given these business, compliance, cost, and latency constraints — which architecture, and why?
The answer choices at Professional level are longer, more plausible, and often use the right vocabulary while drawing the wrong conclusion. You need to know not just what each pattern is, but when the wrong answer would fail.
The Master Pattern
Every module in this course is a variation on one idea:
A thing that looks handled and a thing that has been verified to be handled are different claims.
This is the test key. Every wrong answer on the Professional exam collapses this distinction:
| "Looks handled" | "Verified as handled" |
|---|---|
| Demo ran clean 5 times | Deterministic |
| Control named in a design doc | Control with an owner and evidence artifact |
| Compliant route chosen | Proof of ongoing compliance |
| Confident model output | Correct model output |
| Architecture diagram drawn | Decision rationale recorded |
| Per-call cost quoted | Monthly bill at volume |
| Human review gate exists | Human review gate that doesn't rubber-stamp |
When you see an answer that sounds like it handles the requirement — ask: is it handled, or does it just look handled? The correct answer is almost always the one that can be verified or evidenced.
The 12 Trap Patterns
The exam is built around 12 named failure modes. You'll encounter them in Module lessons — and you'll review them all in the final cheatsheet lesson. Keep these in the back of your mind as you work through the modules:
- Right tradeoff word, wrong conclusion
- Collapsing layers (training behavior ≠ system-prompt enforcement)
- Platform name ≠ configuration
- Presence ≠ verified function
- Confidence ≠ correctness
- Aggregate metric hides tail
- Named-but-unowned = unenforced
- Missing the third tradeoff element (reversal cost)
- Scariest-sounding constraint isn't the binding one
- Everything reviewed = nothing reviewed
- Architectural complexity justified by the wrong reason
- An instruction asked to do a security layer's job

How to Use This Course
- Read each lesson once for comprehension — don't memorize, build the mental model
- After each lesson, try the corresponding domain questions in the practice quiz
- Note which questions you miss — those are your study targets for re-reading
- Do the cheatsheet lesson in the 24 hours before the exam, not weeks before
- Run the full 120-minute exam mode once to calibrate your pacing
The practice quiz at the end has all 63 questions — Practice Mode shows rationale for every wrong answer, Exam Mode gives you the real 120-minute experience.
