Exam Strategy

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

Tactical advice beyond content knowledge - what separates candidates who pass from those who retake.

🗓
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.
