Exam AB-900 is tied to the Microsoft 365 Certified: Copilot and Agent Administration Fundamentals credential. Microsoft's official scope focuses on Microsoft 365 core services and objects, data protection and governance for Microsoft 365 and Copilot, and basic administrative tasks for Copilot and agents.
The correct credential is Microsoft 365 Certified: Copilot and Agent Administration Fundamentals. The exam is Exam AB-900: Microsoft 365 Copilot and Agent Administration Fundamentals. Use that naming when planning study so you do not confuse it with unrelated Azure, Power Platform, or general AI fundamentals exams.
Microsoft's study guide groups the exam into three objective areas: identify the core features and objects of Microsoft 365 services, understand data protection and governance tasks for Microsoft 365 and Copilot, and perform basic administrative tasks for Copilot and agents. Those official areas are the safest way to organize study.
Expect Microsoft 365 tenant objects, workload admin centers, Microsoft Purview, SharePoint data governance, Copilot access, Copilot reporting, pay-as-you-go billing concepts, and agent administration. AB-900 is a fundamentals exam, so it tests recognition of the correct service, tool, or admin action more than deep implementation detail.
Start with the official study guide, review each Microsoft documentation area that maps to the skills measured, and use practice questions to check whether you can choose the right tool for a scenario. Avoid using local practice-bank counts or guessed percentages as evidence for exam emphasis; Microsoft's published study guide is the authority.
