What is the Microsoft AB-900 Exam? Fundamentals

The AB-900: Microsoft 365 Certified: Copilot and Agent Administration Fundamentals is Microsoft's foundational certification validating an administrator's ability to configure, secure, and govern AI-driven productivity workloads. As organizations adopt Microsoft 365 Copilot and build specialized autonomous agents with Microsoft Copilot Studio, IT professionals must understand the administrative guardrails that protect sensitive corporate assets.

Rather than testing abstract programming, the AB-900 evaluates practical administrative literacy. You will be tested on how the Semantic Index and Microsoft Graph work together, how role-based access controls prevent accidental data exposure, and how Microsoft Purview sensitivity labels enforce tenant-wide security boundaries.
