Background

Fabrikam Inc. is a mid-sized healthcare analytics company that provides population health dashboards and predictive insights to regional hospital systems across the United States. Fabrikam Inc. customers rely on near real time analytics to monitor patient flow, staffing needs, and readmission risks. They use multiple traditional forecasting machine learning models for predictions.

Fabrikam Inc. has an established Microsoft Azure footprint. The company uses Jupyter Notebooks that run on a local server as the primary development environment. The data science team is experiencing scalability, asset management and code management issues with the current development platform. Fabrikam Inc. plans to migrate to a cloud- based development environment to mitigate the issues.

Additionally, the company plans to implement a Retrieval-Augmented Generation (RAG)- based chat application for client support. Leadership requires the application to be developed and deployed with a low operational risk.

Current Environment

Fabrikam Inc. operates a single Azure subscription that has the following components:

Azure Data Lake Storage Gen2 that contains de-identified clinical and operational datasets Azure AI Search indexing curated analytical documents and reference materials A small set of Python-based training scripts maintained by data scientists Azure OpenAI Service with deployed foundational models A Microsoft Foundry resource for building a RAG-based solution Evaluation data has manually defined expected responses.

The current challenges faced by the data science team include the following:

Model training jobs are run manually from notebooks.

Experiment tracking is inconsistent Model versions are registered without standardized metadata.

Deployment is performed manually by data scientists, with limited rollback capability.

The team has no standardized evaluation process for generative AI outputs.

The environment currently allows public network access. Authentication relies on user accounts rather than managed identities. Compute targets are manually created and shared across experiments. This has led to resource contention during peak usage.

Business Requirements

Fabrikam Inc. has the following business requirements for the modernization initiative:

Provide a conversational interface that answers analytics questions by using internal documents and datasets.

Ensure that sensitive healthcare-related data is not exposed outside the Fabrikam Inc. Azure tenant.

Enable repeatable and auditable model training and deployment processes.

Support experimentation to compare prompt strategies and fine-tuned models.

Align the model with the ranked preferences and optimize behavior for the long term.

Minimize disruption to existing analytics workloads during rollout.

Technical Requirements

To support the business goals, Fabrikam Inc. identifies these technical requirements:

Use Azure Machine Learning workspaces to centrally manage data assets, models, and environments.

Implement experiment tracking and model versioning for all training jobs.

Orchestrate training and evaluation by using pipelines rather than manually running notebooks.

Deploy traditional machine learning models with support for staged rollout and rollback.

Improve RAG-based solution output quality.

Use the existing evaluation datasets that are based on real data with input-output pairs.

Apply advanced fine-tuning techniques only when prompt engineering is insufficient

Issues and Constraints

Fabrikam Inc. must comply with internal security policies that require the company to restrict network access and avoid long-lived secrets. The data science team has limited Azure DevOps experience, so solutions must favor managed services and automation over custom infrastructure.

Cost predictability is important. Leadership prefers serverless or managed compute options where possible but is willing to approve dedicated compute for stable production workloads.

Problem Statement

Fabrikam Inc. must design and implement an Azure-based AI operations solution that enables reliable training, evaluation, deployment, and iteration of generative AI models. The solution must support experimentation and gradual rollout while ensuring governance, security, and operational stability. The data science and platform teams must collaborate to deliver this solution by using Azure Machine Learning and Microsoft Foundry capabilities.

You need to standardize how Fabrikam Inc. manages machine learning assets.

Which action should you perform first?

  1. Register assets in the Azure Machine Learning registry.
  2. Create a shared Azure Machine Learning workspace.
  3. Deploy a managed online endpoint.
  4. Create a new Microsoft Foundry project.
Show answer and explanation

Correct answer: B. Create a shared Azure Machine Learning workspace.

A shared Azure Machine Learning workspace is the foundational unit that centrally holds data assets, models, environments, jobs, and compute, so it must exist before any standardized asset management can happen. Once the workspace is in place, the team can apply consistent naming, versioning, and experiment tracking to every asset the data scientists produce. Registries, endpoints, and Foundry projects all build on top of that central management plane.

Why the other options are wrong

  • A. A registry is designed to promote and share already curated assets across workspaces and regions, so it is a later step rather than the starting point for standardization.
  • C. Deploying a managed online endpoint serves models that have already been registered and governed, so it does nothing to standardize asset management.
  • D. A Microsoft Foundry project supports the generative AI and RAG work, not the centralized management of traditional machine learning data assets, models, and environments.

Problem Statement

Fabrikam Inc. must design and implement an Azure-based AI operations solution that enables reliable training, evaluation, deployment, and iteration of generative AI models. The solution must support experimentation and gradual rollout while ensuring governance, security, and operational stability. The data science and platform teams must collaborate to deliver this solution by using Azure Machine Learning and Microsoft Foundry capabilities.

You need to isolate training workloads while remaining cost-aware to address Fabrikam Inc.’s issues, constraints, and technical requirements.

What should you implement?

  1. Training jobs that run on a single shared compute cluster
  2. Fixed-size compute cluster
  3. Dedicated compute clusters per experiment
  4. Managed compute targets with autoscaling
Show answer and explanation

Correct answer: D. Managed compute targets with autoscaling

Managed compute targets with autoscaling address all of Fabrikam's requirements: they isolate training workloads by providing dedicated resources for each job, reduce costs through autoscaling that adjusts to actual demand, support experimentation without resource contention, and align with the preference for managed services over custom infrastructure. Autoscaling eliminates the cost waste of fixed resources while providing isolation superior to shared clusters.

Why the other options are wrong

  • A. A single shared compute cluster causes resource contention during peak usage, which is explicitly identified as a current problem.
  • B. Fixed-size clusters lack cost efficiency and cannot adapt to varying workload demands, reducing cost predictability.
  • C. Dedicated clusters per experiment consume unnecessary resources continuously and increase costs without the flexibility of managed autoscaling.

Question 3

You manage an Azure Machine learning workspace. You develop a machine learning model.

You must deploy the model to use a low-priority VM with a pricing discount.

You need to deploy the model.

Which compute target should you use?

  1. Azure Container Instances (ACI)
  2. Azure Machine Learning compute clusters
  3. Local deployment
  4. Azure Kubernetes Service (AKS)
Show answer and explanation

Correct answer: B. Azure Machine Learning compute clusters

Azure Machine Learning compute clusters support low-priority VMs with pricing discounts through spot instances and scale sets configured for cost optimization. This compute target is specifically designed for machine learning workloads and provides the pricing flexibility needed. Azure Container Instances does not support low-priority VMs, local deployment is not cloud-based, and while AKS can use low-priority nodes, it adds unnecessary complexity for standard ML model deployment.

Why the other options are wrong

  • A. Azure Container Instances does not support low-priority VM pricing or spot instances.
  • C. Local deployment does not utilize cloud compute resources and cannot leverage Azure's low-priority VM discounts.
  • D. Azure Kubernetes Service is more complex than necessary for standard ML model deployment and adds operational overhead.

What makes the AI-300 hard

AI-300 is a new exam, not a rename. It is an operations exam that assumes a model can already be trained; what it tests is whether it can be run in production, and then whether the same can be done for a generative AI application.

The first half is classic MLOps on Azure Machine Learning: workspaces, datastores, compute targets, registries, MLflow tracking, AutoML, hyperparameter sweeps, pipelines, managed endpoints, and data drift and retraining triggers. The second half is GenAIOps in Microsoft Foundry: serverless API endpoints versus managed compute, provisioned throughput units, prompt versioning in Git, evaluation with groundedness, relevance, coherence and fluency metrics, tracing and token-cost monitoring, and RAG tuning with chunk sizes, hybrid search and embedding fine-tuning. Bicep, Azure CLI and GitHub Actions run through every domain, so provisioning the infrastructure is expected alongside using it.

Because the exam is only a few months old, there is very little in circulation. This pack has 170 practice questions for the AI-300.
