NEW QUESTION # 145
You have a deployment of an Azure OpenAI Service base model.
You plan to fine-tune the model.
You need to prepare a file that contains training data.
Which file format should you use?
Answer: A
Explanation:
To fine-tune a model in the Azure OpenAI Service, your training data must be in JSONL (JSON Lines) format.
File Requirements
Format: Each line of the file must be a single, valid JSON object.
Encoding: The file must be encoded in UTF-8.
Special Requirement: For some older tools or specific Azure OpenAI use cases, the file may need to include a byte-order mark (BOM).
Size Limits: Individual files typically have a maximum size (e.g., 100 MB per file in some contexts), but you can often upload multiple files.

NEW QUESTION # 146

You use Azure Machine Learning to deploy a model as a real-time web service.
You need to create an entry script for the service that ensures that the model is loaded when the service starts and is used to score new data as it is received.
Which functions should you include in the script? To answer, drag the appropriate functions to the correct actions. Each function may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Load the model when the service starts: init()
Use the model to score new data: run()
Azure Machine Learning scoring scripts for online endpoints use two required entry-point functions: init() and run() . Microsoft explicitly states that the scoring script specified for an online deployment must contain both functions.
The init() function is invoked when the inference container is initialized or started, typically immediately after a deployment is created or updated. It is intended for one-time initialization tasks such as locating the registered model through AZUREML_MODEL_DIR, deserializing the model, and storing it in memory.
Loading the model once during initialization avoids repeatedly loading it for every inference request, which reduces latency and processing overhead.
The run() function is called each time the endpoint receives an inference request. It accepts the incoming request data, transforms or parses the input as required, invokes the loaded model ' s prediction logic, and returns the scoring result. Microsoft describes run() as the function that performs the actual scoring or prediction for each endpoint invocation.
main(), score(), and predict() may exist inside application code or model libraries, but they are not the required Azure Machine Learning scoring-script entry points.
NEW QUESTION # 147
You are preparing training data for a fine-tuning job in Microsoft Foundry.
Real production conversations cannot be used due to compliance requirements.
You need to generate synthetic interaction data that can be used for fine-tuning a generative model.
What should you do?
Answer: C
Explanation:
The correct approach is to generate synthetic prompt-response interactions that reproduce the structure and behavioral patterns of the target task. Microsoft Foundry supports synthetic data generation specifically for cases where real production data is unavailable, scarce, sensitive, or subject to privacy and compliance restrictions. Generated examples can be converted into the structured conversational format required for fine- tuning, such as JSONL containing messages with system, user, and assistant roles.
A simulator or synthetic-data generator can construct representative conversations without exposing genuine customer interactions. This allows the team to create sufficient task-specific examples, review their quality, remove unsuitable samples, and then use the resulting dataset for supervised fine-tuning. Microsoft notes that synthetic data can preserve useful task structure while avoiding reliance on proprietary or sensitive production datasets.
Option A is incorrect because evaluation logs are primarily intended for assessment and observability and are not automatically suitable as training examples. Option C directly violates the requirement because it captures real production traffic. Option D confuses training data with observability artifacts: telemetry logs and traces describe execution behavior and diagnostics rather than producing the prompt-response examples required for fine-tuning.

NEW QUESTION # 148
You are fine-tuning a base language model to analyze customer feedback.
You label examples of support tickets. You must improve classification accuracy by configuring and fine-tuning the base model in Microsoft Foundry.
You need to configure and run fine-tuning.
What should you do first?
Answer: D
Explanation:
In Microsoft Foundry, when configuring and running a fine-tuning job for analyzing customer feedback (e.g., classifying support tickets), you should first enable tracing for all inference calls in the evaluation pipeline.
Tracing is a critical step in the "Evaluate" phase of the fine-tuning workflow, allowing you to capture input/output examples, identify the root cause of classification errors, monitor latency, and analyze model behavior before and after training.
Note:
To fine-tune a model and evaluate it effectively, you should follow this sequence:
1. Enable Tracing for Initial Baseline
Before you fine-tune, you should indeed enable tracing for all inference calls in your existing evaluation pipeline.
Purpose: This creates a clear "paper trail" of how the base model is currently failing.
Benefit: Tracing captures the exact inputs, outputs, and intermediate steps. By analyzing these traces, you can identify if the low accuracy is due to the model not following instructions, missing domain-specific jargon, or struggling with specific ticket categories.
Setup: You can enable Automatic Tracing (currently in preview) in Foundry to log these details to Application Insights without changing your code.
2. Configure and Run Fine-Tuning
Once you have analyzed the traces and prepared your labeled dataset, you can proceed with the fine-tuning job.
3. Continuous Evaluation
After the job completes, you must compare the fine-tuned model against your original traces Reference:

NEW QUESTION # 149
You manage a Retrieval-Augmented Generation (RAG) system that uses Azure AI Search to retrieve documents from an indexed knowledge base.
The system must support the following retrieval requirements:
Queries that include exact policy identifiers must return matching documents even when semantic similarity is low.
Natural-language questions must prioritize semantically relevant documents even when keywords are not an exact match.
You need to configure the retrieval approach to meet the requirements.
How should you configure the retrieval behavior for each requirement? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Different query types require fundamentally different retrieval algorithms. For queries that include exact policy identifiers, keyword or BM25 search is the correct choice because BM25 scores documents based on term frequency and inverse document frequency - an exact match on a specific policy identifier such as POL-
2024-HR-042 scores very highly regardless of semantic context. This is the right approach when semantic similarity is low but exact term matching is critical. For natural-language questions where keywords may not be an exact match, semantic or vector search is the correct choice because vector embeddings capture meaning rather than exact tokens, finding relevant documents even when the user ' s vocabulary differs from the document ' s terminology. Azure AI Search supports both modes through its hybrid search capability, and the correct configuration maps each query type to its optimal retrieval algorithm.
