    Identify AI concepts and capabilities

    The concept half of Azure AI Fundamentals: the six responsible AI principles, how generative models produce output, how to pick and configure a model, and which workload fits a scenario. Every Foundry build in Domain 2 assumes you can reason through these first.

    Inside this domain

    • Describe considerations for fairness in an AI solution
    • Describe considerations for reliability and safety in an AI solution
    • Describe considerations for privacy and security in an AI solution
