A.Global Administrator
B.Copilot Administrator
C.Compliance Administrator
D.Teams Administrator
Explanation: The Copilot Administrator role is purpose-built to manage Microsoft 365 Copilot settings, usage policies, and configurations without requiring full Global Admin privileges, following the principle of least privilege.

A.Settings > Org settings > Copilot
B.Active users > Licenses and apps
C.Reports > Copilot usage
D.Billing > Purchase services
Explanation: Administrators go to Active users, select the user, and use the Licenses and apps panel to assign or remove the Microsoft 365 Copilot add-on license, controlling which individuals can access Copilot features.
3Which report in the Microsoft 365 admin center shows aggregated Copilot feature usage such as active users and which apps are being used?
A.Adoption Score
B.Service Health
C.Copilot Usage Report
D.Message Center
Explanation: The Copilot Usage Report in the Microsoft 365 admin center provides aggregated data on active users, feature-level usage (chat, email, meetings, documents), and adoption trends across the licensed population.
4What does the Microsoft Copilot Dashboard in Viva Insights primarily provide to organizational leaders?
A.Real-time DLP violation alerts from Copilot sessions
B.Usage metrics and employee sentiment about Copilot's helpfulness

B.Whether Copilot can search Bing and the public web to enrich responses
C.Whether Copilot indexes SharePoint sites for the semantic index
D.Whether Copilot can use third-party plugins
Explanation: The web grounding toggle controls whether Microsoft 365 Copilot can query Bing and public web content to supplement organizational data in its responses. Admins in regulated industries may disable this to keep responses strictly within governed internal data.

A.A managed database for storing Copilot conversation history
B.A low-code platform for building, customizing, and deploying AI agents and copilots
C.A Microsoft Purview compliance monitoring tool
D.A SIEM platform for AI security events

7In Copilot Studio, what is a 'topic' and what does it define?
A.A SharePoint knowledge page linked to the agent
B.A conversation flow triggered by specific user intents, containing trigger phrases and response logic
C.A Dataverse table that stores agent responses
D.A Power Automate scheduled flow called by the agent
Explanation: A topic in Copilot Studio is a modular conversation flow that defines how the agent responds to specific user inputs or intents. Each topic contains trigger phrases that activate it and a sequence of nodes (messages, questions, actions) that guide the conversation.
8Which Copilot Studio deployment channel makes a custom agent available directly as a Teams app within Microsoft Teams?
A.Web chat channel
B.Teams channel
C.SharePoint channel
D.Direct Line channel
Explanation: The Teams channel in Copilot Studio enables publishing an agent into Microsoft Teams, where users can interact with it as a Teams app or personal bot, leveraging the Teams interface and identity infrastructure.
9What capability does 'generative answers' provide in a Microsoft Copilot Studio agent?
A.The ability to generate images from user text prompts
B.AI-powered responses from configured knowledge sources when no authored topic matches the user query
C.A way to generate synthetic conversation training data
D.Automatic generation of Power Automate flows from natural language
Explanation: Generative answers uses Azure OpenAI to dynamically generate answers from configured knowledge sources—websites, SharePoint, documents—when no authored topic's trigger phrases match the user's input.
10What does BYOA (Bring Your Own Agent) mean in the Microsoft 365 Copilot ecosystem?
A.Importing personal ChatGPT conversations into Microsoft Teams
B.Integrating externally built agents into Microsoft 365 Copilot or Teams via agent manifests or plugin registrations

Frequently Asked Questions

What is the AB-900 exam?

The AB-900 (Microsoft 365 Copilot and Agent Administration Fundamentals) exam validates foundational knowledge for supporting an AI-enabled Microsoft 365 environment. It covers core M365 services, data protection with Microsoft Purview, and Copilot/agent administration.

How is AB-900 different from MS-900?

MS-900 (Microsoft 365 Fundamentals) covers broad Microsoft 365 services, security, and licensing. AB-900 specifically focuses on administering Microsoft 365 Copilot and agents, with deep coverage of Purview governance, Copilot data access, and agent lifecycle management.

Does AB-900 certification expire?

Yes, AB-900 requires annual renewal via a free online assessment on Microsoft Learn. This is different from older Dynamics 365 fundamentals exams which do not expire. The renewal keeps your knowledge current as Copilot features evolve rapidly.

What are the main AB-900 exam domains?

AB-900 has three domains: Data Protection and Governance for Microsoft 365 and Copilot (35-40%), Core Features and Objects of Microsoft 365 Services (30-35%), and Basic Administrative Tasks for Copilot and Agents (25-30%).

What is DSPM for AI on the AB-900 exam?

Data Security Posture Management (DSPM) for AI is a Microsoft Purview capability that helps organizations discover and manage AI activity, identify sensitive data accessed by Copilot, and maintain a strong security posture as AI usage scales across the organization.

What background do I need for AB-900?

You should be familiar with Microsoft 365 services and admin centers (Exchange Online, SharePoint, Teams, Entra, Purview), core security concepts like Zero Trust and conditional access, and AI-driven productivity tools. No formal prerequisites are required but Microsoft 365 familiarity is strongly recommended.
