The AB-100 exam contains approximately 40 questions. Question types include multiple choice and scenario-based questions that test your ability to plan, design, and deploy agentic AI business solutions using Microsoft Copilot Studio, Foundry, and Dynamics 365.

The AB-100 exam duration is 120 minutes. The extra time reflects the expert-level depth — scenario questions require careful analysis of multi-agent architecture decisions, ALM processes, and responsible AI governance requirements.

The AB-100 exam costs $165 USD. Microsoft offers free exam vouchers through Microsoft Learn challenges, AI Cloud Partner Program benefits, and virtual training days — check the Microsoft Learn events page before registering at full price.

AB-100 is a challenging expert-level exam because it spans the full lifecycle of agentic AI solutions — from ROI analysis and AI adoption strategy through multi-agent architecture design to ALM, monitoring, and responsible AI governance. You need hands-on experience with Copilot Studio, Microsoft Foundry, and Dynamics 365 AI features to handle the scenario-based questions.

Most candidates spend 6–8 weeks preparing. Focus first on the Deploy domain (40–45% of the exam) — it covers ALM processes, monitoring, governance, and responsible AI which are heavily tested. Then cover Design (Copilot Studio agents, Foundry, task and autonomous agent patterns) and finally Plan (AI adoption strategy, ROI analysis, multi-agent solution design). Hands-on labs with Copilot Studio and Foundry are essential.

AB-100 covers three domains: Plan AI-powered business solutions (25–30%) — AI adoption strategy, Cloud Adoption Framework for AI, multi-agent solution design, ROI analysis, prompt libraries, small language models, and AI Center of Excellence; Design AI-powered business solutions (25–30%) — task agents, autonomous agents, prompt-response agents, MCP in Copilot Studio, Computer Use, agent behaviors, Foundry tools, Dynamics 365 AI customizations; Deploy AI-powered business solutions (40–45%) — monitoring agents, testing strategies, ALM for Copilot Studio and Foundry, responsible AI principles, security and governance for agents, data residency, and audit trails.

Yes, AB-100 follows Microsoft's standard renewal policy for role-based certifications — you must renew annually via a free online assessment on Microsoft Learn. Renewal assessments become available 6 months before your certification expires and can be retaken for free until you pass.
