You need to change the state of the model version to meet the requirements.
What should you do?
正解：C
質問 # 171
A team is building a Retrieval-Augmented Generation (RAG) system.
The team observes that the retrieved documents are often irrelevant or incomplete.
You need to improve retrieval accuracy.
What should you adjust?
正解：D
解説：
Chunk size and overlap directly affect the precision and completeness of information retrieved in a RAG architecture. Microsoft identifies effective chunking as a critical part of successful RAG implementation. If chunks are too large, they can contain excessive unrelated information, reducing retrieval precision because the vector representation covers multiple concepts. Conversely, chunks that are too small can omit necessary surrounding context or separate related information across chunk boundaries, resulting in incomplete retrieval.
Overlap helps preserve semantic continuity between adjacent chunks. Microsoft recommends using overlap particularly with fixed-size chunking because relevant facts or concepts can span chunk boundaries. The optimal chunk size and overlap should therefore be evaluated against representative documents and queries rather than treated as fixed constants. Microsoft specifically notes that larger chunks can preserve contextual richness, while appropriately configured overlap prevents contextual information from being lost at segmentation boundaries.
Temperature controls generation variability , not document retrieval. Token limits constrain how much content a model processes but do not inherently make retrieval more relevant. Embedding strategy can also influence retrieval quality, but given the stated symptom of irrelevant or incomplete retrieved passages , tuning chunk size and overlap is the directly targeted remediation.

質問 # 172
You retrain an existing model.
You need to register the new version of a model while keeping the current version of the model in the registry.
What should you do?
正解：B
解説：
Model version: A version of a registered model. When a new model is added to the Model Registry, it is added as Version 1. Each model registered to the same model name increments the version number.

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 recommend an experiment-tracking strategy that ensures consistent experiment results. What should you recommend?
正解：C
解説：
Scenario:
The current challenges faced by the data science team include the following: Experiment tracking is inconsistent To support the business goals, Fabrikam Inc. identifies these technical requirements: Implement experiment tracking and model versioning for all training jobs.
In Azure-based AI operations, integrating MLflow with Azure Machine Learning (Azure ML) provides a unified interface to track experiments, version models, and manage the lifecycle of both traditional ML and Generative AI workloads.
Direct Implementation Strategy
To ensure consistent experiment results and comparison of prompt strategies versus fine-tuned models, use the following architectural approach:
Centralized Tracking: Configure the MLflow tracking URI to point to your Azure ML Workspace.
This allows all logs (from local notebooks, remote training jobs, or Prompt Flow) to aggregate in a single "Experiments" dashboard.
Prompt Strategy Comparison: Use Azure ML Prompt Flow to develop and test prompt variants.
Prompt Flow automatically logs metrics (like groundedness and relevance) which can be viewed alongside fine-tuned model metrics in the Azure ML Studio.
Model Versioning: Use the MLflow Model Registry hosted within Azure ML. Each successful training or fine-tuning run should be registered as a new version of a named model, providing a clear lineage from data to deployment.

質問 # 174
A financial services company is deploying Microsoft Foundry to host generative AI workloads that process regulated customer data. The Microsoft Foundry environment must prevent any public network exposure while still allowing services managed by Microsoft Foundry to communicate with dependent Azure resources.
Security auditors require that all traffic to and from the Microsoft Foundry resource remain on private networks, with no public endpoints available.
You need to configure the Microsoft Foundry environment so that network access is restricted while maintaining full platform functionality.
Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point. Choose two .
正解：C、D
解説：
Microsoft ' s Azure AI Foundry documentation describes two required configurations for fully private network isolation. First, configure a managed virtual network for the Foundry resource: this provisions a Microsoft-managed VNet that encapsulates all internal service communications - the Foundry control plane communicates with dependent Azure services such as storage, key vault, and cognitive services over private endpoints within this managed VNet, so no traffic crosses the public internet. Second, disable public network access to the Foundry resource: this removes the public endpoint entirely, ensuring that only clients on approved private networks via private endpoint connection can reach it. Together, these two actions ensure all traffic remains on private networks with no public endpoints available, satisfying the security auditor requirement for complete network isolation.
