Prepare for the AI-300 exam: Operationalizing Machine Learning and Generative AI Solutions

Prepare for the AI-300 exam, Operationalizing Machine Learning and Generative AI Solutions, with 6 practice tests of 250 exam style questions each — 1,500 questions in total — built to match the format and depth of the live exam. Passing AI-300 earns the Microsoft Certified: Machine Learning Operations Engineer Associate credential, the successor to the retired DP-100.

Exam Domain Coverage

Each AI-300 practice test mirrors the real exam blueprint and its five weighted domains:

Design and implement an MLOps infrastructure (19%)
Implement machine learning model lifecycle and operations (30%)
Design and implement a GenAIOps infrastructure (24%)
Implement generative AI quality assurance and observability (14%)
Optimize generative AI systems and model performance (13%)

You will practice the same tooling the AI-300 exam covers: Azure Machine Learning, Microsoft Foundry, MLflow, GitHub Actions, Bicep, and the Azure CLI, alongside RAG optimization, fine-tuning, and AI evaluation and observability.

Detailed Explanations

Every AI-300 question includes a detailed explanation. You get the reasoning behind the correct answer, a clear note on why each distractor is wrong, and references to the official Microsoft Learn documentation so you can study further at the source. This turns each attempt into a focused study session rather than just a score.

Exam Format

The real AI-300 exam runs 120 minutes with a passing score of 700 and is delivered in English, and it targets MLOps and GenAIOps engineers who already work with Azure Machine Learning and Python. Use these AI-300 practice tests to find your weak areas, close them, and build the confidence to pass on your first attempt.
