| Issuer | Microsoft |
| Certification lane | Microsoft 365 Copilot and Agent Administration Fundamentals |
| Exam code | AB-900 |
| Main scope | Microsoft 365 tenant readiness, identity, permissions, data governance, Copilot administration, agents, monitoring, and adoption |
| IT Mastery status | Sample questions available |
| Area | What to know | Common trap |
|---|---|---|
| Tenant readiness | Licensing, users, groups, admin roles, service health, and configuration | Enabling Copilot before tenant basics are clean |
| Identity and access | Microsoft Entra, permissions, groups, conditional access, and reviews | Assuming Copilot ignores existing permissions |
| Data governance | SharePoint, OneDrive, Teams, sensitivity labels, retention, and oversharing | Letting AI surface poorly governed content |
| Copilot and agents | Admin controls, availability, policy, lifecycle, and user enablement | Treating agents as unmanaged personal tools |
| Adoption and monitoring | Training, feedback, usage, risk signals, and support path | Measuring only license assignment |
| Distinction | How to decide |
|---|---|
| License vs readiness | A license permits use; readiness makes use safe and valuable. |
| Permission vs label | Permissions control access; labels classify and protect content. |
| Copilot vs agent | Copilot assists in Microsoft experiences; agents handle designed tasks and workflows. |
| Admin role vs user role | Admin roles manage tenant settings; user roles govern daily work access. |
| Adoption metric vs security signal | Adoption shows use; security signals show risk and control issues. |
For AB-900 misses, identify whether the scenario is about tenant setup, identity, data governance, Copilot controls, agents, monitoring, or adoption. Fundamentals answers usually improve readiness before rollout.
