Claude Certified Architect - Professional
The whole certification as bullets and pictures, with the official exam keywords and the real situations behind each one.
Module 1
Claude Platform & Solution Design
Foundations
- Non-determinism forces evaluation frameworks
- Context is finite token budget
- Confidence is not validity
- External system owns fast-changing truth
Important to learn · exam keywords

Design around Claude's properties like an engineer designs around steel
Platform Map
- Entry points, interfaces, routes: three layers
- Every deployment involves all three
- Patterns assemble the seven primitives
- Use fewest primitives necessary

A house: front door, wiring, and the power street
Decomposition
- Three owners: Claude, systems, humans
- Systems own already-reliable work
- Decomposition produces a delegation map
- Model doing lookups drifts silently
Important to learn · exam keywords

Do not have the chef weigh every cup
Patterns
- Predictability versus autonomy places each pattern
- Agent trajectory IS the control flow
- Four sub-patterns: chaining, routing, parallelization, evaluator-optimizer
- Tightest constraint, often error cost, decides

Workflow is a relay; agent is a mapless explorer
Orchestration
- Orchestrator decomposes, subagents carry parts
- Fan-out splits units, runs parallel, synthesizes
- Lost orchestrator state often unrecoverable
- Shared trace identifier keeps runs reconstructable

Reuse & Recap
- Caching needs a stable prefix
- Static before dynamic content
- Skill for cross-team versioned procedure
- Governance rules out routes first

Module 2
Enterprise Integration & Production
Evals
- Climb grading ladder, cheapest reliable first
- Code-based grading: unambiguous, near-zero, never drifts
- Calibrate LLM judge against human labels
- Criterion: behavior, threshold, failure modes

POC to Production
- Demo hides cost, latency, reliability, failure modes
- Model cost and latency, design against p95
- Backoff, fallback chains, circuit breakers placed by layer
- Caching helps stable prompt, risks consistency window

Sizing & Feasibility
- Feasibility: verdict plus boundary conditions
- Check POC moves the business metric first
- Name boundary conditions before committing
- ROI needs net, ranges, measured baseline

Integration
- Compliance eliminates routes and entry points first
- Entry points span Direct API to MCP
- Minimum-necessary data, reference IDs over fields
- Design-time observability catches data-scope violations

A/B & Recap
- Hypothesis, random assignment, primary metric, sample size
- Fix metric and sample size before running
- Probabilistic outputs need larger, noise-aware samples
- Significance is not practical significance

Module 3
Responsible AI, Safety & Risk
The Safety Stack
- Constitution prioritizes safe, ethical, helpful behavior
- Constitution ignorant of your domain policy
- Deployment rules enforced only at inference-time
- Assumed domain rules fail silently, no error

Guardrails
- Fail-open control worse than none
- Chain input, output, tool-call authorization in series
- Combine classifiers and deterministic rules; fail differently
- Screen retrieved content and tool outputs too
- Untrusted Skill is a supply-chain risk

Fairness
- Passing outputs still yield unequal outcomes
- Four injection points for unequal outcomes
- Skewed corpus or leading frame skews outcomes
- Log inputs, context, output, routing per decision
- Different audiences need different explanations

Human Review
- Human review is a finite attention budget
- Route low-confidence irreversible or high-cost decisions
- Weight cost and reversibility over confidence
- Give reviewers inputs, output, flag reason
- Pre-action approval blocks harm but adds latency

Compliance & Recap
- Compliant entry point prerequisite, not proof
- Each obligation needs control, owner, evidence artifact
- Evidence artifact most often missed
- Reviewer accepts live proof, not design docs
- Training-excluded data still retained for logging

Module 4
Stakeholder Engagement, Lifecycle & GTM
Discovery
- Structured elicitation across four fixed categories
- Deliverable is a translation table
- Experience words signal more discovery needed
- Must-prove ignored fails an audit

Tradeoffs & GTM
- Present decision as a package
- Reversal cost makes it informed
- Sort objections: governance, capability, compliance
- Wrong evidence erodes trust
