AB-900: Copilot & Agent Administration Fundamentals

As the author of this practice-exam course for AB-900: Copilot & Agent Administration Fundamentals, I designed a focused, exam-first study path to help you move from familiarity to mastery. This course contains five full-length practice exams with over 250 realistic questions and thorough explanations for every answer — not only why an option is correct, but why the others are incorrect — so you learn from each attempt and track real improvement. The material and question distribution mirror the topics and administrative scenarios emphasized by Microsoft for AB-900, which cover Microsoft 365 Copilot, agent administration, governance, and core Microsoft 365 admin concepts.
