AB-900 Skills measured breakdown

Exam AB-900 Skills Measured

Microsoft's Exam AB-900 study guide organizes skills measured into three official objective areas. Use those areas as the study structure instead of relying on local practice-bank counts or guessed exam emphasis.

Identify Microsoft 365 Services and Objects

This area covers core Microsoft 365 administration knowledge. Microsoft lists topics such as license types, Microsoft 365 admin center organization settings, Exchange Online mailboxes and distribution groups, SharePoint sites and libraries, Teams objects, Microsoft Entra objects, least privilege, and audit log review.

Understand Data Protection and Governance

This area centers on Microsoft Purview and governance risks for Microsoft 365 and Copilot. Study sensitivity labels, retention concepts, audit, Communication Compliance, Insider Risk, DLP, oversharing, external sharing, data access governance reports, and controls that affect what Copilot can discover.

Perform Basic Copilot and Agent Administration

This area covers the features and administration of Microsoft 365 Copilot and agents. Microsoft includes built-in Copilot capabilities, agents, monthly license versus pay-as-you-go concepts, agent use cases, Copilot license assignment, usage and adoption reporting, billing policies, and agent lifecycle monitoring.

How to Use the Skills List

Treat the skills measured list as a checklist of Microsoft tools and decisions. For each bullet, ask which admin center, report, governance feature, license model, or agent feature is involved. That approach keeps study aligned with Microsoft's scope and avoids turning practice metadata into exam guidance.
