What makes the AB-100 hard
AB-100 is the expert level architect exam for AI in Microsoft business applications, and it is wide. The blueprint, skills measured as of 22 July 2026, spans Dynamics 365 Sales, Service, Contact Center, Finance and Supply Chain, Power Platform, Copilot Studio, Microsoft 365 Copilot and Microsoft Foundry, and expects candidates to decide between them rather than know one deeply.
The biggest domain, at 40 to 45%, is Deploy: monitoring agents and reading telemetry, testing strategies for agents and custom models, ALM for Copilot Studio agents, Foundry agents and custom models, and a full section on responsible AI, security and governance covering prompt manipulation, data residency and audit trails. Plan covers the Cloud Adoption Framework AI adoption process, build versus buy versus extend, and ROI analysis. Design covers task, autonomous and prompt-and-response agents, MCP and computer use in Copilot Studio, and the Power Platform Well-Architected Framework.
Because the exam is only a few months old, there is very little in circulation. This pack has 120 practice questions for the AB-100.
