You complete the fine-tuning of a generative model in Microsoft Foundry. The fine-tuned model now appears as a new model variant in your development environment.
The deployment process must ensure that proper validation and control is maintained.
You need to promote the fine-tuned model from development to production.
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.
정답：
설명：
Explanation:
Correct sequence:
* Create a Developer Tier deployment.
* Evaluate and validate the model.
* Create a Global Standard deployment.
The fine-tuned model should first be deployed using the Developer Tier because Microsoft specifically positions this deployment type for fine-tuned model candidate evaluation rather than production use .
Developer Tier deployments provide a cost-efficient environment for testing custom models and do not provide a production SLA.
After deployment, the model should be evaluated and validated . Microsoft Foundry supports running the model through the playground and the Evaluations service to assess the deployed candidate against expected quality, safety, and task-performance criteria. Microsoft explicitly documents that evaluations can be executed against a deployed fine-tuned model candidate and compared with other model versions.
Only after the candidate satisfies the required validation criteria should it be promoted to a Global Standard deployment for production inference. Global Standard is designed for general production workloads and provides substantially more appropriate production characteristics than Developer Tier.
Register the fine-tuned model version is the distractor here. The scenario already states that fine-tuning is complete and the resulting model variant exists in Microsoft Foundry; the required promotion workflow is therefore test deployment # validation # production deployment .

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 manage a Microsoft Foundry project.
You are evaluating two RAG solutions.
When generating answers, the solutions display the following results:
* The first solution displays low completeness and low utilization.
* The second solution displays low completeness and high utilization.
You need to address the issues found during evaluation.
Which action should you perform first for each issue? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Explanation:
Low completeness, low utilization: Increase chunk size
Low completeness, high utilization: Verify relevant chunks were retrieved For low completeness and low utilization , the retrieved context neither completely answers the query nor is fully used by the model. Microsoft recommends investigating the chunking strategy when completeness is poor. For fixed-size chunking specifically, increasing the chunk size can preserve additional surrounding context and reduce fragmentation of information across separate chunks. This can improve the probability that each retrieved chunk contains enough information to support a complete answer. Decreasing top-k would retrieve fewer chunks and could further reduce completeness, while reducing chunk size can fragment the required context even more.
For low completeness and high utilization , the model is already making effective use of the context supplied to it, but that context does not contain enough information to answer the entire question. Therefore, the first diagnostic step is to verify that all relevant chunks were actually retrieved . Microsoft specifically recommends determining whether additional relevant chunks exist but were not returned and, if so, investigating the retrieval process, ranking strategy, or search configuration.
Prompt tuning is less appropriate as the first step because high utilization indicates that the model is already using the supplied context.

질문 # 109
You manage a Microsoft Foundry project.
You are developing a solution to generate content based on text and images. The solution requires the ability to manage high-volume processing and avoid disruptions to the online workloads.
You need to deploy the solution.
Which deployment type and large language model (LLM) should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
정답：
설명：
Explanation:
LLM model: GPT-4o
Deployment type: Global batch
GPT-4o is the correct model because it is a multimodal model capable of processing both text and image inputs while generating text-based responses. This directly satisfies the requirement to generate content based on a combination of text and images. DALL-E is primarily designed for image generation rather than general multimodal language processing, while Whisper is designed for speech recognition and audio transcription.
Global batch is the correct deployment type because Microsoft specifically positions it for large-scale, high- volume asynchronous processing . Global Batch accepts large groups of requests and processes them using a separate enqueued-token quota. Critically, Microsoft states that this separate quota helps ensure that batch processing does not disrupt online workloads , which directly matches the scenario. It also provides a target turnaround of approximately 24 hours and is optimized for use cases such as large-scale content generation.
Standard deployments are better suited to interactive or lower-volume inference. Global provisioned deployments provide reserved predictable throughput, but they do not provide the specific workload isolation benefit described for asynchronous Global Batch processing.
