NEW QUESTION # 76
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?
Answer: B
Explanation:
Azure Private Endpoints are network interfaces that connect your Azure ML workspace to your Virtual Network using a private IP address from the VNet ' s address space. Once a private endpoint is created and DNS is configured, all traffic to the workspace - including the Studio UI, REST API, and SDK calls - travels entirely over Microsoft ' s private backbone rather than the public internet. The workspace ' s public endpoint can then be completely disabled. Azure Firewall (option A) filters traffic at the network layer but still requires the workspace to have a public IP. Network Security Groups (option C) control traffic within VNets but cannot block the public endpoint of a PaaS service. Service endpoints (option D) keep traffic on the Azure backbone but the workspace still has a public-facing address. Private endpoints are the only option that fully removes the public network presence.

NEW QUESTION # 77
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.
Answer:
Explanation:
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.

NEW QUESTION # 78
A team runs training jobs by using multiple Azure Machine Learning pipelines.
The team must ensure that all runs use the same Python packages and system libraries. The solution must allow dependency updates to be versioned without modifying training code.
You need to configure the workspace so that runtime dependencies are consistent and reusable.
Which four 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.
Answer:
Explanation:
Explanation:
To ensure runtime dependencies are consistent and reusable, first create a conda.yaml or requirements.txt file that lists all Python packages and system libraries required by your training code - this file is the single source of truth for your runtime. Next, create an Environment object using the Azure ML Python SDK v2 with a name and reference to the conda.yaml file, specifying the base Docker image. Then register the Environment by calling ml_client.environments.create_or_update, which publishes it to the workspace registry with an auto-incremented version. Finally, reference the registered environment by name and version in all pipeline job steps. Azure ML will build or retrieve the cached Docker image and use it as the execution container. This approach means updating dependencies only requires modifying the conda.yaml and registering a new version - training code remains unchanged.

NEW QUESTION # 79
An Azure Machine Learning workspace contains multiple registered versions of a model that is used in production.
An older model version must no longer be deployable, but it must remain available for compliance review and potential rollback.
You need to change the state of the model version to meet the requirements.
What should you do?
Answer: C
Explanation:
Azure Machine Learning ' s model registry supports three lifecycle states: Active (the default, fully usable state), Archived (not deployable but still accessible for review), and Deleted (permanently removed).
Archiving is precisely designed for this scenario: it ensures that operations teams cannot accidentally select the old version for a new deployment, while compliance officers can still inspect it, compare its metrics to newer versions, and reactivate it quickly if a rollback is needed. Deleting (option B) would permanently remove the version, making compliance review and rollback impossible and violating both requirements.
Unregistering (option D) is not a standard Azure ML operation; deletion is the removal action. Archiving the training dataset (option A) is unrelated to the model version ' s deployability. Archiving creates a soft-block on deployment while preserving the full artifact history.

NEW QUESTION # 80
You have an Azure Machine Learning (ML) model deployed to an online endpoint.
You need to review container logs from the endpoint by using Azure Ml Python SDK v2. The logs must include the console log from the inference server with print/log statements from the models scoring script.
What should you do first?
Answer: C
