NEW QUESTION # 116
Case Study 1 - Fabrikam Inc.
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 isolate training workloads while remaining cost-aware to address Fabrikam Inc.'s issues, constraints, and technical requirements. What should you implement?
Answer: B
Explanation:
Scenario: Issues and Constraints: Cost predictability is important. Leadership prefers serverless or managed compute options where possible but is willing to approve dedicated compute for stable production workloads.
Managed compute targets with autoscaling are the best choice for Azure Machine Learning training workloads when serverless or managed options are preferred and cost predictability is critical.
Best Implementation: Managed Compute with Autoscaling
This option, specifically using Azure Machine Learning compute clusters (AmlCompute), aligns with all your requirements:
Managed Infrastructure: Azure handles the creation, patching, and lifecycle of the virtual machines, reducing management overhead.
Cost Predictability & Efficiency: Autoscaling allows you to set a minimum of zero nodes. This ensures you only pay for compute while a job is running, preventing costs from idle resources.
Scalability: It can automatically scale up to a multi-node cluster to handle large datasets or distributed training jobs.
Enterprise Governance: Administrators can enforce cost control by setting quotas at the subscription or workspace level.

NEW QUESTION # 117
You manage an Azure Machine Learning workspace. You train a model named model1.
You must identify the features to modify for a differing model prediction result.
You need to configure the Responsible Al (RAI) dashboard for model1.
Which three actions should you perform in sequence? To answer move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

NEW QUESTION # 118
Fabrikam Inc. needs to improve the performance of a GPT-5 model based on the stated technical requirements.
Which action should you perform first?
Answer: A
Explanation:
The first action should be to evaluate the model output . Fabrikam already has evaluation data containing manually defined expected responses, and the technical requirements explicitly state that the organization must use its existing evaluation datasets based on real data with input-output pairs . Microsoft Foundry supports evaluating a model against an existing curated dataset to establish measurable baseline performance before optimization. Evaluation results can identify weaknesses in accuracy, relevance, groundedness, safety, or other quality dimensions and provide objective evidence for subsequent changes.
This sequencing is critical because Fabrikam also requires that advanced fine-tuning be applied only when prompt engineering is insufficient . Therefore, immediately fine-tuning the model would bypass the required baseline evaluation and optimization process. Fine-tuning should be driven by demonstrated performance gaps, not applied automatically.
Deploying directly to production is also inappropriate because leadership requires low operational risk and gradual rollout. Production traffic should not be used as the first evaluation mechanism when curated evaluation data already exists. Synthetic interaction data is useful when evaluation coverage is insufficient, but Microsoft specifically positions synthetic generation as an option when an adequate test dataset is unavailable. Fabrikam already has suitable evaluation data.
Study Guide Reference: Optimize generative AI systems and model performance - evaluate model performance, benchmark against curated datasets, iterate on prompts, and apply advanced fine-tuning when justified.
NEW QUESTION # 119
A machine learning model is deployed to production in Azure Machine Learning and is actively serving predictions for a business application. The model was trained by using a historical dataset that represented expected input patterns at the time of deployment.
The team working on the model must ensure the following:
Changes in input data distribution are detected.
Appropriate actions are triggered when predefined thresholds are exceeded.
You need to configure monitoring to meet the requirements.
Which configuration should you use for each requirement? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Azure Machine Learning ' s data drift monitor solves the first requirement: it continuously compares the statistical distribution of live inference input features against the baseline training data distribution, flagging when significant drift occurs. For the second requirement of triggering appropriate actions when thresholds are exceeded, Azure Monitor alert rules are configured on the drift metrics. When the drift coefficient exceeds a defined threshold, Azure Monitor fires an alert that can invoke Logic Apps, send emails, trigger an Azure ML retraining pipeline, or post to Teams. This two-layer approach - ML-specific drift detection backed by Azure Monitor alerting - is the Microsoft-recommended pattern for production model monitoring. The data drift monitor handles detection, while Azure Monitor handles the operational response, keeping the two concerns cleanly separated.

NEW QUESTION # 120
Hotspot Question
You have an Azure Machine Learning workspace.
You plan to set up logging and tracking experiments by using MLflow Tracking.
You need to log the accuracy as a numerical value and the training loss as a plot.
How should you complete the commands? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: log_metric("log", num1)
Log Numerical Metrics
To track a single numerical value that changes over time (like accuracy or evaluation scores), you use the mlflow.log_metric() function. This enables Azure Machine Learning to plot the value on a performance graph automatically.
Box 2: log_artifact(img1)
Log Plots and FilesTo save external files, images, or plots generated during training, you use the mlflow.log_artifact() function. This uploads the specified file (in this case, your saved Matplotlib image) to the run's artifact storage.
