AB-650

Administering Microsoft 365 AI services requires controlling the information that Copilot can access, securing agent identities, and maintaining reliable tenant operations. The AB-650 exam assesses these responsibilities alongside identity protection, compliance, and workload administration. It is associated with the Microsoft 365 Certified: Microsoft 365 and AI Services Administrator Associate certification and is intended for administrators who manage both traditional productivity services and emerging AI capabilities.

Microsoft Entra Conditional Access and Tenant Security

Identity governance is a major part of this examination. Candidates should understand user and group management, administrative units, delegated roles, Privileged Identity Management, and Microsoft Graph PowerShell. Authentication methods, multifactor authentication, self-service password reset, and risk-based Conditional Access policies also require attention.

Security responsibilities extend into Microsoft Defender for Office 365, where administrators investigate collaboration threats, configure protection policies, and respond to alerts. Microsoft Purview introduces another layer through sensitivity labels, retention policies, Data Loss Prevention, and Data Security Posture Management.

For AB-650, distinguish identity restrictions from information protection. A user may have permission to open a document while separate policies restrict how AI services process its contents.

Copilot Readiness, SharePoint Permissions, and Data Governance

Microsoft 365 Copilot administration begins with tenant readiness, licensing, and the accessibility of organizational information. Candidates should understand how SharePoint and OneDrive permissions, search configuration, and overshared content affect Copilot experiences.

Important administrative distinctions include:

• SharePoint access permissions versus Purview DLP restrictions.
• Copilot Search configuration versus external connector management.
• Sensitivity labeling versus retention and data lifecycle controls.
• Tenant-wide Copilot settings versus individual user experiences.

Related workloads include Exchange Online mailboxes, Microsoft Teams administration, meeting transcription, and Microsoft 365 Backup. These services provide the operational foundation on which AI-enabled collaboration depends.

Agent Registry, Microsoft Entra Agent ID, and Agent 365

AI agent administration introduces responsibilities beyond managing human users. Candidates should understand agent identity lifecycles, ownership, access packages, sharing restrictions, and Conditional Access for agents. Microsoft Entra Agent ID and Agent 365 support distinct aspects of identity management and agent governance.

The agent registry provides controls for discovering, reviewing, approving, blocking, and managing organizational agents. Administrators must also consider connected tools, third-party integrations, sensitive data exposure, and compliance monitoring.

Operational monitoring covers Copilot adoption reports, AI service consumption, tenant health, and the Copilot Control System. These measurements help administrators assess how AI services are used and identify configuration or governance concerns.

A web-based practice test runs in the browser with nothing to install, while downloadable PDF questions and answers can be printed and annotated for offline revision. For AB-650, combine these formats with hands-on administration of Entra policies, Purview controls, Copilot settings, and agent access decisions.
