問題 #82
An Azure Machine Learning workspace processes sensitive training data.
The workspace must NOT be accessible from the public internet.
You need to restrict network access.
Which configuration should you implement?
答案：C
解題說明：
To ensure an Azure Machine Learning (AML) workspace handling sensitive data is not accessible from the public internet, you must disable the Public Network Access flag and implement Private Endpoints. This configuration creates a private link between your Azure Virtual Network (VNet) and the workspace, ensuring traffic never traverses the public internet.

問題 #83
You are reviewing a dataset that will be used for an advanced fine-tuning job in Microsoft Foundry.
The fine-tuning job uses preference comparison data.
You review the following dataset excerpt.
For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.
答案：
解題說明：
Explanation:
Preference comparison data with chosen versus rejected response pairs is the input format for Direct Preference Optimization (DPO) or RLHF-style fine-tuning - an advanced fine-tuning technique available in Microsoft Foundry. A valid DPO dataset record must have three fields: a prompt as the input, a chosen field containing the preferred response, and a rejected field containing the less preferred response. The file must be in JSONL format with UTF-8 encoding, where each line represents one complete preference pair. When evaluating statements about this dataset, mark True if the dataset contains all three required fields and chosen responses represent higher-quality outputs than rejected ones. Mark False if the format is incompatible with DPO requirements, if the required rejected field is missing, or if the chosen and rejected responses appear to be of equivalent quality with no clear preference signal.

問題 #84
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 work in Microsoft Foundry with a prompt flow.
You must manually evaluate prompts and compare results across prompt variants.
You need to capture the inputs, outputs, token usage, and latencies for each flow run for the evaluation.
Solution: Configure Azure Monitor to collect logs from the workspace. Use the logs to perform prompt evaluation.
Does the solution meet the goal?
答案：B
解題說明：
Azure Monitor is valuable for production observability , but it is not the appropriate mechanism for the stated development-time requirement: manually inspecting individual prompt-flow executions and comparing prompt variants with their inputs, outputs, token consumption, and latency.
Prompt flow provides purpose-built run outputs and tracing . Microsoft documents that after a flow execution, the Outputs experience exposes detailed flow inputs and outputs. When tracing is enabled, the Trace view provides execution duration and token information and lets the developer expand individual steps to inspect their inputs and execution details.
Prompt flow also directly supports variants and batch/evaluation runs. Multiple variants can be executed and compared, while the run details expose per-test-case inputs, outputs, token counts, duration, and evaluation results. Microsoft explicitly states that multiple runs can be selected to compare their metrics and outputs.
Azure Monitor/Application Insights can collect operational metrics such as token consumption and flow or node latency for deployed applications, but that telemetry is primarily intended for monitoring and troubleshooting rather than the interactive prompt-variant evaluation workflow described here.
Therefore, the proposed solution does not meet the goal .
Study Guide Reference: Implement generative AI quality assurance and observability - prompt evaluation, tracing, debugging, token consumption, latency, and prompt-variant comparison.
問題 #85
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?
答案：C
解題說明：
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.
Study Guide Reference: Optimize generative AI systems and model performance - synthetic data generation, supervised fine-tuning datasets, simulator-based interaction generation, privacy-preserving model customization, and training-data preparation.
