                                                  問題 #48
                                                  A data science team completes multiple training runs within an experiment by using MLflow.
                                                  The team wants to store a selected model in Azure Machine Learning so that it can be versioned and deployed later.
                                                  The model must be versioned centrally for reuse across environments.
                                                  You need to version the trained model.
                                                  Which two actions should you perform? Each correct answer presents part of the solution.
                                                  Choose two.
                                                  NOTE: Each correct selection is worth one point.

                                                  • A. Export the model files to local storage.
                                                  • B. Register the model in the Azure Machine Learning workspace.
                                                  • C. Locate and capture the model artifacts from the outputs of the training run.
                                                  • D. Tag the training experiment with a name.

                                                  答案：B,C

                                                  解題說明：
                                                  To set up versioning for a trained model in an Azure Machine Learning (Azure ML) workspace using MLflow, you must capture the model artifacts during the training run and then register the model into the centralized registry.
                                                  [A]
                                                  1. Capture Model Artifacts
                                                  During each training run, use the MLflow SDK to log the model. This ensures that all necessary files (the model binary, environment dependencies, and the MLmodel metadata) are stored as run outputs in the workspace.
                                                  Manual Logging: Use a flavor-specific method like mlflow.sklearn.log_model(model,
                                                  "model_path") within an active run.
                                                  Automatic Logging: Call mlflow.autolog() before starting your training. This automatically captures metrics, parameters, and the model artifacts for supported frameworks.
                                                  Artifact Location: Once logged, artifacts are typically found in the outputs/ folder of the specific run, accessible via the Azure Machine Learning Studio.
                                                  [B]
                                                  2. Register the Model
                                                  After identifying the best-performing run, you register it to the Model Registry. This creates a named, versioned entity that can be accessed across different environments for deployment.
                                                  To set up versioning for an MLflow model in Azure Machine Learning (Azure ML) that is accessible across different environments, you should use a centralized Azure ML Registry. While a standard Azure ML Workspace acts as an MLflow server for individual experiments, an Azure ML Registry is the specifically designed feature for sharing models, environments, and components across multiple workspaces and environments within an Azure tenant.
                                                  3. Centralized Reuse
                                                  By registering the model in the workspace's registry, you establish a single source of truth. You can then load this specific version in any environment (e.g., staging or production) using its registry URI: models:/<model_name>/<version_or_alias>.
                                                  Incorrect:
                                                  [Not D]
                                                  Must use an Azure ML Registry (Central).

                                                  問題 #49
                                                  Drag and Drop Question
                                                  An organization is adopting Microsoft Foundry to support multiple generative AI projects across different teams. Microsoft Foundry platform administrators require centralized governance.
                                                  Development teams need isolated environments for experimentation and deployment.
                                                  Shared policies must be enforced consistently while allowing teams to work independently.
                                                  You need to configure the Microsoft Foundry environment to meet the requirements.
                                                  Which Microsoft Foundry components should you configure? To answer, move the appropriate configurations to the correct responsibilities. You may use each configuration once, more than once, or not at all. You may need to move the split bar between panes or scroll to view content.
                                                  NOTE: Each correct selection is worth one point.

                                                  解題說明：


                                                  問題 #50
                                                  An organization maintains separate Azure Machine Learning workspaces for development and production.
                                                  Both environments must use the same validated assets without duplicating them.
                                                  Assets must be shared across workspaces while maintaining centralized governance and version control.
                                                  You need to enable reuse of assets across workspaces without copying them.
                                                  What should you do?

                                                  • A. Publish the asset to an Azure Machine Learning registry.
                                                  • B. Publish the asset as a pipeline component.
                                                  • C. Enable workspace-level Git integration and sync assets between repositories.
                                                  • D. Create a shared Azure Machine Learning environment that includes the asset.

                                                  答案：A

                                                  To share validated assets between development and production workspaces while maintaining centralized governance and version control, you should use Azure Machine Learning Registries.
                                                  Microsoft Learn
                                                  Unlike standard workspaces, registries are workspace-agnostic. They act as a central catalog that decouples assets from individual environments, allowing you to "promote" a model or environment from Dev to Prod without manual duplication or data drift.

                                                  問題 #51
                                                  Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
                                                  After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear on the review screen.
                                                  You manage a Retrieval-Augmented Generation (RAG) application built on Microsoft Foundry.
                                                  The application retrieves documents from an indexed knowledge base and generates answers for internal users.
                                                  Recent feedback indicates that answers are fluent but sometimes include information that is not supported by the documents that were retrieved.
                                                  You need to evaluate whether a proposed change improves RAG answer quality by using supported and measurable techniques.
                                                  Solution: Review user feedback comments collected after deployment to determine whether answers appear more accurate.
                                                  Does the solution meet the goal?

                                                  • A. Yes
                                                  • B. No

                                                  答案：A

                                                  解題說明：
                                                  Correct:
                                                  * Review user feedback comments collected after deployment to determine whether answers appear more accurate.
                                                  Relying solely on user feedback comments is not the proper immediate action for evaluating this specific issue but it is still the best choice.
                                                  Evaluate whether your proposed change improves the Retrieval-Augmented Generation (RAG) system by reducing hallucinations (unsupported information), you need to measure faithfulness and context relevance using automated, quantifiable metrics.
                                                  The proper course of action is to implement an LLM-as-a-Judge framework using an open-source evaluation library like Ragas or TruLens.
                                                  Recommended Evaluation Plan
                                                  Establish a baseline: Run your current RAG pipeline through a test dataset of 50-100 representative user queries.
                                                  Capture the outputs: Save the user query, the exact retrieved document snippets, and the generated response for every test.
                                                  Apply the change: Deploy your proposed modification (e.g., altered prompt, different temperature, or re-ranking algorithm).Run the evaluation: Pass the test dataset through the updated pipeline to generate a new set of responses.
                                                  Compare the metrics: Use the framework to score both sets of data and mathematically verify if the change reduced unsupported claims.
                                                  Incorrect:
                                                  * Compare embedding vector dimensions used by the retrieval pipeline before and after the change.
                                                  Comparing embedding vector dimensions is not a valid or effective method for measuring RAG answer quality. Vector dimensions (e.g., 1536 or 3072) are static architectural properties of your embedding model. They do not reflect factual accuracy, semantic grounding, or the rate of hallucinations in your text generation.
                                                  * Measure token throughput and average response latency before and after applying the proposed change.
                                                  Measuring token throughput and latency is not the correct action to solve this specific problem.

                                                  Developers must be able to create and update project assets but must not be able to change resource-level configurations.
                                                  You need to enforce least privilege access for the engineers and developers.
                                                  Which two actions should you perform? Each correct answer presents part of the solution.
                                                  Choose two.
                                                  NOTE: Each correct selection is worth one point.

                                                  • A. Share a single API key across all teams.
                                                  • B. Assign a resource-level Azure AI Administrator role to the platform engineers.
                                                  • C. Disable Microsoft Entra ID authentication for the Microsoft Foundry resource.
                                                  • D. Assign the Azure AI Developer role to the developers.

                                                  答案：B,D

                                                  解題說明：
                                                  [A]
                                                  Engineer Permissions (Hub Scope)
                                                  Engineers require the ability to manage infrastructure, networking, and global security settings.
                                                  Role: Azure AI Administrator or Contributor.
                                                  Assignment Scope: Assign at the Foundry Hub/Resource level.
                                                  Capabilities: They can manage virtual networks, customer-managed keys, and shared connections (e.g., Azure OpenAI) that all projects inherit.
                                                  [C]
                                                  Developer Permissions (Project Scope)
                                                  Developers should be restricted from changing the underlying resource configurations but need full access to their specific AI workloads.
                                                  Role: Azure AI Developer or Project Contributor.
                                                  Assignment Scope: Assign strictly at the Foundry Project level.
                                                  Capabilities: This allows them to create and update project assets (agents, flows, evaluations) and deploy models without permission to modify Hub-level infrastructure or security settings Reference:
