AI-900 Verified 2026 Edition

AI-900 Practice Exam

AI-900, Microsoft's original Azure AI Fundamentals exam, was retired in mid-2026 and replaced by AI-901. This practice test still covers the retired objectives: AI workloads and responsible AI principles, machine learning on Azure, computer vision, natural language processing, and generative AI services. Candidates should prepare for the current AI-901 exam instead.
