質問 # 100
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: Measure token throughput and average response latency before and after applying the proposed change.
Does the solution meet the goal?
正解：A
解説：
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.

You need to standardize how Fabrikam Inc. manages machine learning assets.
Which action should you perform first?
正解：B
解説：
In Azure Machine Learning, a workspace is the top-level resource that acts as a centralized hub for every ML activity. It stores experiments, pipelines, datasets, models, environments, and compute targets all in one place.
Before you can register assets or deploy endpoints, the workspace itself must exist and be shared across the team. Fabrikam ' s core challenge is inconsistent experiment tracking, ad-hoc versioning, and no standardized deployment path - all symptoms of the absence of a single, governed workspace. Option A (registering assets) is a subsequent action only possible after the workspace exists. Option C (online endpoint) is a deployment concern, not an asset-management foundation. Option D (Foundry project) is appropriate for generative AI workloads, not for the traditional ML pipeline standardization described here. The workspace is the prerequisite that makes every other governance action possible.

質問 # 102
A team plans to deploy a large foundation model in Microsoft Foundry as part of a new enterprise AI capability.
Different business units across the team ' s organization will access the model from various internal applications.
You need to deploy a foundation model by minimizing latency.
Which deployment type should you use?
正解：C

質問 # 104
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.
You have an Azure Machine Learning workspace. You connect to a terminal session from the Notebooks page in Azure Machine Learning studio.
You plan to add a new Jupyter kernel that will be accessible from the same terminal session.
You need to perform the task that must be completed before you can add the new kernel.
Solution: Delete the Python 3.6 - AzureML kernel.
Does the solution meet the goal?
正解：A
解説：
No. Removing the existing Python 3.6 - AzureML kernel is not a prerequisite for adding a new kernel. Azure Machine Learning supports multiple installed Jupyter kernels on the same compute instance, and notebooks can select among those kernels without requiring one existing kernel to be removed first. Microsoft states that the notebook environment automatically discovers all Jupyter kernels installed on the connected compute instance.
The supported new-kernel workflow begins by creating a separate environment, for example with conda create --name newenv, and activating it. The required pip and ipykernel packages are then installed in the environment before registering it with Jupyter by using python -m ipykernel install --user --name newenv.
Deleting an existing AzureML kernel provides no technical benefit to that workflow. Microsoft also explicitly cautions users not to delete Conda environments or Jupyter kernels they did not create , because doing so can interfere with built-in Jupyter/JupyterLab functionality on the compute instance.
Therefore, the existing Python 3.6 kernel should remain untouched; the new kernel should be installed alongside it in its own environment.
