Exam Strategy

Tips to pass Microsoft 365 Certified: Copilot and Agent Administration Fundamentals (AB-900) on your first attempt

Practical advice for applying what you know, managing questions and preparing for exam conditions.

🗓

MS-900 was retired on March 31, 2026 and can no longer be scheduled — if you're studying now, you're preparing for AB-900, a substantially different exam, not a refreshed MS-900.

🔍

Only about 30-35% of MS-900 knowledge carries over directly (core M365 services, identity fundamentals, basic security concepts) — the rest is new AI-administration content.

⏭

Data Protection and Governance for Copilot is the single largest domain (37%) — go deep on Microsoft Purview: DSPM for AI, sensitivity labels, and SharePoint oversharing controls.

📊

Understand the difference between Copilot (built-in AI assistant across M365 apps) and agents (custom AI workers organizations build and deploy) — the exam tests administration of both.

🔁

Know your five key admin portals: Microsoft 365 admin center, Exchange admin center, SharePoint admin center, Teams admin center, and Microsoft Entra/Purview.

🧪

Agent lifecycle management (creation, approval, monitoring) spans both the Microsoft 365 admin center and the Power Platform admin center — don't assume it's all in one place.

📝

AB-900 has no prerequisites but assumes more baseline M365 familiarity than MS-900 did — if you're completely new to Microsoft 365, budget extra study time on core services first.

Reviews

What candidates say after passing

★★★★★

SharePoint vs. OneDrive use case distinction is tested far more specifically on MS-900 than candidates expect.Edureify AI's collaboration scenarios - personal productivity vs. team document management vs. intranet publishing - made the right service selection automatic within a few weeks of practice.

Omar A.

IT Manager

★★★★★

Microsoft Purview vs. Microsoft Defender is the compliance vs. security distinction the exam tests throughout.Edureify AI's scenarios required me to classify every data protection question as compliance (Purview) or security (Defender) before selecting a solution. That classification instinct prevented many wrong answers.

Stephanie L.

Data Engineer

★★★★★

M365 licensing tier differences are more significant than candidates assume. Business Basic vs. Standard vs. Premium have meaningful capability gaps, especially in security features.Edureify AI's plan selection scenarios - match the plan to the stated compliance and security requirements - built that decision framework.

Clara V.

Business Analyst

★★★★★

Entra ID vs. on-premises Active Directory is a conceptual distinction that cloud-new candidates often miss.Edureify AI's identity scenarios made the cloud-native vs. on-premises boundary explicit - Conditional Access, SSO, and MFA live in Entra ID, not traditional AD - which is exactly how the exam tests it.
