Sample Exam Questions

Try these 12 original sample questions for Microsoft AB-100. They are designed for self-assessment and are not official exam questions.

Question 1

Topic: solution architecture

A business wants an agent that can answer questions and trigger approved workflows. What should the architect define first?

Question 5

Topic: data grounding

A finance agent must answer from approved policy documents and ERP data. What should be designed?

  • A. Grounded retrieval, connector permissions, freshness, citations, and source governance.
