AB-100 covers three skill areas: Plan AI-powered business solutions (25-30%), Design AI-powered business solutions (25-30%), and Deploy AI-powered business solutions (40-45%). Deploy carries the highest weight and includes ALM, monitoring, responsible AI, security, and governance.
How much does the AB-100 exam cost?

How should I study for the AB-100 exam?
Lead with the Deploy domain (40-45%) since it carries the most weight: ALM, monitoring, responsible AI, security, residency, and audit. Then cover Design (Copilot Studio, Foundry, Dynamics 365 extensibility, MCP, Computer Use) and Plan (strategy, ROI, build/buy/extend).

AB-100 is an Expert-level architect credential focused on agentic-first business solutions across Copilot Studio, Microsoft Foundry, Dynamics 365, Power Platform, and Microsoft 365 Copilot. Unlike Azure AI Engineer (AI-102), which targets engineers building AI services, AB-100 targets solution architects designing multi-agent systems, governance, and ALM at enterprise scale.
