AB-900 Frequently Asked Questions

Everything you need to know about the AB-900 Microsoft 365 Copilot and Administration Fundamentals certification

What is the AB-900 exam?
AB-900 is a Microsoft fundamentals certification that validates knowledge of Microsoft 365 services, data protection and governance for Microsoft 365 and Copilot, and basic administrative tasks for Copilot and agents. It's designed for IT professionals and administrators who work with Microsoft 365 and Microsoft Copilot environments.
How hard is the AB-900 exam?
AB-900 is a fundamentals-level exam, but it covers a broad range of topics including Microsoft Purview, Copilot licensing models, and agent administration. Candidates with hands-on Microsoft 365 experience should expect 2-3 weeks of preparation. Our practice questions are calibrated slightly harder than the real exam so you're over-prepared on test day.
What does AB-900 cover?
AB-900 covers three main domains: Microsoft 365 core services including Exchange Online, SharePoint, Teams, and Entra ID (30-35%); data protection and governance tasks for Microsoft 365 and Copilot including Microsoft Purview, DLP, sensitivity labels, and DSPM for AI (35-40%); and basic Copilot and agent administration including licensing, billing, usage monitoring, and agent lifecycle management (25-30%).
Is AB-900 worth getting in 2026?
Yes. As Microsoft Copilot adoption grows rapidly in enterprises, administrators who understand Copilot governance, data protection, and agent management are in high demand. AB-900 validates the foundational skills needed to manage Copilot deployments responsibly and securely, making it increasingly valuable for M365 administrators.
What score do I need to pass AB-900?
You need 700 out of 1000 to pass. Microsoft uses scaled scoring, so it's not a simple 70%. Our practice tests help you consistently score above 80% so you have a comfortable margin on exam day.
