NEW QUESTION # 60
you create an Azure Machine learning workspace named workspace1. The workspace contains a Python SOK v2 notebook mat uses Mallow to correct model coaxing men's anal arracks from your local computer.
Vou must reuse the notebook to run on Azure Machine I earning compute instance m workspace.
You need to comminute to log training and artifacts from your data science code.
What should you do?
Answer: A
NEW QUESTION # 61
Hotspot Question
A team retrains a machine learning model on a weekly basis by using updated training data.
The team must be able to rerun any previous experiment by using the exact data that was available at the time it was originally run. The solution must preserve historical versions of the data without duplicating training scripts.
You need to manage the data so that experiments can be reproduced reliably.
Which workspace actions should you perform? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: Create a versioned dataset
Track data changes over time.
Creating a versioned dataset in your machine learning workspace configuration is the correct and industry-standard way to solve this.
Versioned datasets allow you to decouple your training scripts from your data state. This approach satisfies all your constraints without duplicating code or creating messy infrastructure.
Enables Reproducibility: Every time you run a training job, you log the specific dataset version used (e.g., v1, v2, v3). To rerun a historical experiment, you simply call that specific version identifier.
Prevents Code Duplication: Your training scripts remain identical. They accept a dataset version as an input parameter rather than pointing to hardcoded file paths.
Tracks Weekly Updates: When the weekly data refresh occurs, you register the new data as v+1 in the workspace registry, keeping a clean chronological ledger.
Box 2: Use the data asset in the experiment
Associate a specific dataset version with a run.
To best associate a specific dataset version with a run in the workspace, you should use the data asset in the experiment.
Automatic Lineage: Registering data as a versioned data asset automatically tracks which exact version was used in which specific run.
Exact Reproducibility: You can look back at any historical run and instantly identify or retrieve the precise data state used at that moment.
No Script Duplication: Your training scripts remain decoupled from the data, satisfying your requirement to preserve history without changing code.
Incorrect:
[Pass the storage key at runtime]
Passing a storage key at runtime only connects the run to a storage location, not a specific, immutable version of the data at a frozen point in time.

NEW QUESTION # 62
You deploy a new model version to a managed online endpoint. You must test it with 10% traffic and automatically roll back if latency or error rate increases beyond threshold. What should you configure?

NEW QUESTION # 63

You review the following Azure CLI command and the relevant Bicep excerpt.
(Non-relevant sections are omitted.)
You need to validate what the snippet will do before it is merged. For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
The command deploys the resources into an existing resource group named rg-foundry-dev: Yes The system-assigned managed identity defined in the template will automatically be inherited by all Microsoft Foundry projects: No To deploy this template to a different subscription, you must modify the Bicep file to include a subscriptionId parameter: No The first statement is Yes . The command uses az deployment group create --resource-group rg-foundry-dev, which performs an Azure Resource Manager deployment at resource-group scope . Microsoft documents that the target resource group must already exist; if it does not, it must be created before running the resource- group deployment.
The second statement is No . The Bicep declaration assigns a system-assigned managed identity to the Foundry resource itself . A Microsoft Foundry project is a child resource and can have its own managed identity . Microsoft explicitly shows project creation with " identity " : { " type " : " SystemAssigned " } and separately discusses assigning permissions to a project ' s managed identity. Therefore, the parent ' s system- assigned identity is not automatically inherited as the identity of every project.
The third statement is No . Because targetScope = ' resourceGroup ' , the same Bicep template can be deployed to a resource group in another subscription without adding a subscriptionId parameter. Azure CLI supports the global --subscription argument, or the active subscription can be changed with az account set.
NEW QUESTION # 64
You are implementing hyperparameter tuning by using Bayesian sampling for an Azure ML Python SDK v2-based model training from a notebook. The notebook is in an Azure Machine Learning workspace. The notebook uses a training script that runs on a compute cluster with 20 nodes.
The code implements Bandit termination policy with slackjactor set to 0.2 and a sweep job with max_concurrent_trials set to 10.
You must increase effectiveness of the tuning process by improving sampling convergence.
You need to select which sampling convergence to use.
What should you select?
Answer: C
Explanation:
To improve the sampling convergence and effectiveness of your Bayesian hyperparameter sweep, you must decrease the value of max_concurrent_trials (for example, setting max_concurrent_trials = 4).
Decrease max_concurrent_trials
Bayesian sampling is a fundamentally sequential algorithm. It relies entirely on the outcomes of previously completed trials to calculate and select the next optimized set of hyperparameters.
The Problem: Setting max_concurrent_trials = 10 forces the optimization engine to kick off 10 trials at the exact same time. Because none of these 10 overlapping trials have completed or generated metrics yet, they cannot learn from one another. This high parallelism compromises the intelligence of the algorithm, turning your structured Bayesian sweep into a less effective random sampling process.
The Solution: Reducing max_concurrent_trials to a smaller number (such as 4) allows sets of trials to complete sequentially. This ensures the optimizer captures enough historical performance data to intelligently direct subsequent runs, achieving significantly better convergence.
