NEW QUESTION # 71
You create an Azure Machine Learning workspace.
You must use the Python SDK v2 to implement an experiment from a Jupyter notebook in the workspace. The experiment must log a list of numerical metrics.
You need to implement a method to log a list of numerical metrics.
Which method should you use?
Answer: D
Explanation:
To log a list of numerical metrics using the Azure Machine Learning Python SDK v2, you should use the mlflow.log_metric() method within a loop, or mlflow.log_metrics() to log them simultaneously as a dictionary.

NEW QUESTION # 72
You manage an Azure Machine Learning workspace named workspace1 by using the Python SDK v2. You create a General Purpose v2 Azure storage account named mlstorage 1. The storage account includes a publicly accessible container named mlcontainer 1. The container stores 10 blobs with files in the CSV format.
You must develop Python SDK v2 code to create a data asset referencing all blobs in the container named mlcontainer 1.
You need to complete the Python SDK v2 code.
How should you complete the code? To answer, select the appropriate options in the answer area . NOTE:
Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Because you want to reference all blobs in a container rather than a single file, the correct asset type is AssetTypes.URI_FOLDER. This type points to a directory-level URI, allowing Azure ML to traverse all files within it. For a publicly accessible Azure Blob Storage container, the URI follows the pattern
https://storage_account.blob.core.windows.net/container_name/. You then create the Data object with the correct type, path, name, and version parameters, and register it in the workspace using ml_client.data.
create_or_update. Do not use AssetTypes.URI_FILE, which references a single file. Do not use AssetTypes.
MLTABLE unless you have an MLTable YAML descriptor. URI_FOLDER is the correct choice for referencing a collection of CSV blobs in an Azure Blob Storage container, allowing Azure ML to discover and process all files within the specified path.

NEW QUESTION # 73
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 # 74
You run Azure Machine Learning training experiments. The training scripts directory contains 100 files that includes a file named .amlignore. The directory also contains subdirectories named ./outputs and ./logs.
There are 20 files in the training scripts directory that must be excluded from the snapshot to the compute targets. You create a file named .gitignore in the root of the directory. You add the names of the 20 files to the .gitignore file. These 20 files continue to be copied to the compute targets.
You need to exclude the 20 files.
What should you do?
Answer: B
Explanation:
To exclude the 20 files from the training snapshot, you must add the file names to the .amlignore file located in the root of your training scripts directory.
Why the Files Are Still Copying
Azure Machine Learning training experiments use a specific order of precedence when creating a directory snapshot for compute targets:
.amlignore takes absolute priority: If an .amlignore file exists in the directory, Azure ML only respects the rules inside it. It completely ignores any .gitignore file present.
.gitignore is a fallback: Azure ML only respects .gitignore rules if an .amlignore file does not exist in the directory. Because you have both files, the .gitignore file is being completely bypassed.

NEW QUESTION # 75
You manage an Azure Machine Learning workspace That has an Azure Machine Learning datastore.
Data must be loaded from the following sources:
* a credential-less Azure Blob Storage
* an Azure Data Lake Storage (ADLS) Gen 2 which is not a credential-less datastore You need to define the authentication mechanisms to access data in the Azure Machine Learning datastore.
Which data access mechanism should you use? To answer, move the appropriate data access mechanisms to the correct storage types. You may use each data access mechanism once, more than once, or not at all. You may need to move the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
