Microsoft 365 Copilot and Agent Administration Fundamentals
AB-900
Prepare for AB-900 with scenario-based questions covering Microsoft 365 Copilot and agent administration fundamentals across core services, security, identity, and governance. This track focuses on practical operational decisions such as licensing, access control, data protection, and monitoring. The set is designed to build confidence in managing Copilot and agent capabilities responsibly in real organizational environments.

Target Audience
Designed for Microsoft 365 administrators, security/compliance practitioners, support leads, and cross-functional teams adopting Copilot and agent capabilities. It is suitable for professionals who need to coordinate licensing, access, governance, and operational controls in Microsoft 365 environments.
Prerequisites
No strict prerequisite certification is required, but familiarity with Microsoft 365 core workloads (Exchange Online, SharePoint, Teams, Entra) is strongly recommended. You should understand identity/access basics, conditional access, auditing, data protection concepts, and operational governance workflows. Practical exposure to AI-enabled productivity tools and modern admin-center operations will improve readiness significantly.

Recognition Scope
Microsoft Certified: Copilot and Agent Administration Fundamentals — a globally recognized entry-level credential. It renews annually via a free online assessment on Microsoft Learn.
Exam Domains
Identify core functions and objects of Microsoft 365 services
Understand data protection and governance for Microsoft 365 and Copilot
Perform basic administration tasks for Copilot and agents
Recommended Study Plan
- Week 1: Map Microsoft 365 core objects and admin centers — which center to use for each task (Microsoft 365/Exchange/SharePoint/Teams/Entra/Purview/Power Platform) and how licenses gate feature access.
- Week 2: Solidify security and identity — the three Zero Trust principles, authentication vs authorization, Microsoft Entra, Conditional Access, SSO, MFA, PIM, and Identity Secure Score.
- Week 3 (largest weight): Focus on data protection and governance — the Purview solutions (sensitivity labels, DLP, Insider Risk, Communication Compliance, DSPM for AI, Data Lifecycle) and internalize that "Copilot only uses existing permissions" plus SharePoint oversharing (DAG report, restricted access control).
- Week 4: Finish Copilot and agent administration — monthly subscription vs pay-as-you-go, Researcher vs Analyst vs custom agents, license assignment, usage (Copilot Analytics), prompt management, and agent approval/lifecycle.
- Before the exam: run timed mocks to quickly pick "which center, Purview solution, or license model" fits each requirement.

Frequently Asked Questions
Q. What is the AB-900 exam?
A. It is an entry-level certification for administering Microsoft 365 Copilot and agents (exam code AB-900). It assesses Microsoft 365 core objects and admin centers, security and identity (Zero Trust, Entra, Conditional Access), data protection and governance with Microsoft Purview, and basic Copilot/agent administration. No coding is required; the key skill is deciding which center, solution, or license model fits a requirement.
Q. Which area weighs the most, and what are common traps?
A. Data protection and governance (35–40%) is the largest. Recurring items: distinguishing Purview solutions (sensitivity labels = protect, DLP = prevent risky sharing, retention = lifecycle) and the fact that "Copilot grants no new access — it only uses a user's existing permissions." Oversharing is a pre-existing permissions problem, not a Copilot flaw, and is addressed with the SharePoint DAG report and restricted access control. Confusing admin centers (agents live in the Power Platform admin center) is another trap.
Q. What is the passing score and prep time?
A. You need 700 out of 1000 to pass. As a fundamentals exam, 2–4 weeks of focused study is usually enough. The certification renews annually via a free online assessment. When your mock-exam errors in distinguishing Purview solutions and picking the right admin center decline, you are generally in a safe range.
Q. How is AB-900 different from MS-900?
A. MS-900 (Microsoft 365 Fundamentals) broadly covers Microsoft 365 services, licensing, and subscriptions. AB-900 builds on that but focuses specifically on administering Copilot and agents and on data protection and governance with Microsoft Purview. They share foundational topics (admin centers, identity, security), but AB-900 centers on how Copilot accesses organizational data and how to govern it safely. Taking MS-900 first helps but is not required.
Q. Do I need hands-on experience with Copilot and Purview?
A. Not required. But even at fundamentals level, knowing "which admin center does what" from the actual UI flow makes the scenario questions much easier. If you can, walk through the Microsoft 365 admin center, the Microsoft Purview portal, and the Power Platform admin center in a trial/demo tenant, and watch the flows for sensitivity labels, DLP, Copilot license assignment, and creating an agent. If hands-on is not possible, build a table that maps each task to its center and solution instead.
Q. How do practice questions and the timed mock exam differ?
A. Practice questions are solved by topic with answer explanations to shore up weak areas; the timed mock exam is taken like the real thing. Both use original questions with AI tutor explanations.
Q. Is this similar to exam dumps?
A. PasslyExam does not provide leaked dumps. Our content is built from official guides and public exam objectives, then tuned to reflect realistic question patterns and difficulty distribution. The focus is practical readiness with explanation-based learning, not memorization of leaked items.
