AI-300 Machine Learning Operations Engineer Practice Exams

Prepare for the Microsoft AI-300 Machine Learning Operations Engineer Associate exam with hands-on, scenario-based practice

These AI-300 practice tests are for engineers preparing for the Microsoft Certified: Machine Learning Operations (MLOps) Engineer Associate credential. The exam is also called Operationalizing Machine Learning and Generative AI Solutions. It covers two production stacks together: traditional machine learning on Azure Machine Learning, and generative AI applications and agents on Microsoft Foundry. This course helps you practice running both of them reliably in production.

Why this course

AI-300 rewards practical operations judgment. You need to know which deployment option fits a workload, why a pipeline fails, how to catch drift before users notice, and how to measure whether a generative AI app is grounded and safe. Every question here starts from a realistic engineering situation and asks for the best next step. All questions are original, mapped to the current skills outline, and updated as Microsoft revises the exam.

What’s inside, by exam domain

• MLOps infrastructure: Azure Machine Learning workspaces, datastores, compute, environments, components, and registries; identity, access, and network isolation; infrastructure as code with Bicep, Azure CLI, and GitHub Actions; and Git source control

• Machine learning model lifecycle: experiment tracking with MLflow, automated machine learning, hyperparameter tuning, distributed training, and training pipelines; model registration, versioning, and responsible AI evaluation; real-time and batch endpoints, progressive rollout, and safe rollback; and drift detection with retraining triggers

• GenAIOps infrastructure: Foundry resources and projects, managed identities and role-based access, private networking, deploying and selecting foundation models, provisioned throughput, and prompt design, variants, and version control

• Generative AI quality and observability: test datasets, quality metrics such as groundedness and relevance, risk and safety evaluations, automated evaluation workflows, and monitoring of latency, token cost, logging, and tracing

• Generative AI optimization: tuning retrieval-augmented generation with chunking, similarity thresholds, embedding models, and hybrid search; A/B testing; and fine-tuning with synthetic data from development through production

How the explanations help you learn

Every question includes a detailed explanation for every answer option. You learn why the correct choice works in that scenario, and why each of the other choices fails. A wrong option might use the wrong endpoint type, leave a security gap, miss a metric, or add cost for no benefit. These are the operational trade-offs the exam tests and the ones you face on the job.

Who it’s for

• Machine learning engineers, data scientists, and DevOps or platform engineers who deploy and maintain AI workloads on Azure

• Candidates moving to AI-300 from the retired Azure Data Scientist path
