These resources target the English AB-100 objectives effective October 14, 2026. This is an incoming version at the September 27, 2026 source review. If you test before October 14, use the objectives that apply on your exam date. Localized exams can update later; confirm your language and exam date with Microsoft.

## Target domains

Weight ranges are not guaranteed question counts. Summary and detail agree as reviewed.

## 1. Confirm your version and starting point

Record your intended exam date and language. Read the official audience profile and current credential requirements. Compare the effective-date heading with your appointment. Use the checklist to distinguish what you can explain, what needs practice, and what needs a documentation refresh.

**Leave with:** Exam date and language; selected objective version; first checklist pass.

## 2. Plan around a business outcome

Choose a small scenario, such as routing a service request to the right team. Define success, data boundaries, and a non-AI baseline before selecting a platform. Compare building, buying, and extending. State ROI assumptions rather than promising savings.

**Leave with:** A requirement, measurable acceptance criteria, constraints, and a short option comparison.

## 3. Design a bounded solution

Identify the agent role, grounding sources, allowed actions, caller identity, and approval points. Compare candidate platform capabilities against the same requirement. Trace one happy path and one denied or failed action. Record facts that still require current product documentation or a lab.

**Leave with:** A simple architecture sketch and a decision record with a credible alternative.

## 4. Make deployment and operation testable

Define quality and safety test cases, telemetry, ownership, release gates, and rollback. Review least privilege, data residency, auditability, and prompt-manipulation risks. Practice with non-sensitive data in an authorized sandbox; check access and cost before provisioning.

**Leave with:** A test matrix, monitoring plan, and change/rollback note.

## 5. Return to evidence, then repeat

Work through the official learning path to address the gaps you found. Revisit the complete objective bullets in the study guide, not only the ten grouped areas here. Update Explain, Practice, and Refresh separately. Reopen decisions when product documentation, constraints, or the objective version changes.

**Leave with:** Evidence links, an honest remaining-gap list, and a next-review date.
