Explanation:
Azure Machine Learning infrastructure can be described as Infrastructure as Code using ARM templates, Bicep, or Terraform. To make provisioning fully automated, two separate concerns must be addressed. First, the trigger: a CI/CD system like GitHub Actions or Azure DevOps Pipelines must detect changes to IaC template files in the repository, configured through a branch-push or pull-request trigger. Second, the execution: the CI/CD pipeline runs the provisioning commands such as az ml workspace create or bicep deploy non-interactively using a service principal or managed identity, eliminating the need for a human to run scripts manually. Together, these two mechanisms deliver the GitOps-style automation that modern MLOps practices require, ensuring every template change automatically results in a consistent, auditable infrastructure update.

Explanation:
Deploy resources from a pipeline: Azure CLI Commands
Define Azure resources declaratively: Bicep templates
Azure CLI Commands should be used to deploy resources from an automation pipeline. Azure Machine Learning supports integration with CI/CD platforms such as Azure DevOps and GitHub Actions, and Microsoft documents the Azure CLI with the Machine Learning extension as a standard mechanism for automating resource provisioning, training pipelines, model deployment, and other MLOps operations. Azure CLI commands can be executed non-interactively within pipeline stages, making them appropriate for repeatable automated deployments.
Bicep templates should be used to define Azure infrastructure declaratively. Bicep is Microsoft ' s domain- specific Infrastructure-as-Code language for Azure Resource Manager. Instead of specifying individual imperative provisioning steps, a Bicep file describes the desired state of Azure resources. Azure Resource Manager then determines the deployment operations required to reach that state. This provides repeatable, version-controlled, consistent infrastructure across development, testing, and production environments.
Bicep deployments can also be invoked directly through Azure CLI commands such as az deployment group create, allowing the declarative infrastructure definition and automated deployment mechanism to work together in an MLOps CI/CD pipeline.

正確答案:
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.
A team manages prompts that are used by a generative AI application built on Microsoft Foundry. Multiple developers contribute prompt updates, and changes must be reviewed and tracked over time.
The team requires that:
Prompt changes are reviewed before being applied to the version in production.
Previous prompt versions can be restored if issues occur.
Prompt updates follow the same governance practices as the application code.
You need to implement a controlled process for managing and updating prompts in production.
How should you manage prompt updates to meet the requirements? To answer, move the appropriate actions to the correct requirements. You may use each action 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.

正確答案:
Explanation:
All three requirements point to Git as the underlying mechanism, but each uses a different Git capability. For reviewing changes before production: a branch-based workflow where prompt changes are made on feature branches and merged to the main branch only after pull request approval enforces the review gate. For restoring previous versions: Git ' s commit history and tag system provide a precise, immutable record of every prompt state, and a git revert or checkout to a specific commit SHA restores any prior version instantly.
For governance parity with application code: by storing prompts in the same Git repository as application code, all the same CI/CD, branch protection, code review, and audit trail policies apply automatically. The alternatives such as Blob Storage or embedded configuration files lack native review workflows, branch protection, and full audit history.

正確答案:
Explanation:
Correct sequence:
* Deploy a new model version.
* Validate the behavior of the new version.
* Update the model settings on the production route.
The safe approach is to deploy the new model side by side with the existing production deployment rather than modifying the currently serving model immediately. Microsoft Foundry documentation explains that a newly available model version can be tested through a separate deployment, allowing teams to evaluate behavioral differences without affecting existing production requests.
After deployment, validate the behavior of the new version against representative production workloads.
Validation should cover response quality, latency, errors, structured-output compatibility, tool-calling behavior, safety characteristics, and application-specific acceptance criteria. Microsoft ' s model-migration guidance explicitly places validation before production rollout and recommends proving that the new configuration meets defined quality requirements before broad exposure.
Once validation succeeds, update the model settings on the production route so that the application ' s existing production entry point directs requests to the validated deployment. This preserves the stable application-facing endpoint while changing the backend model in a controlled manner.
Shift 100% of traffic to the new version is not the appropriate intermediate safe-promotion action because immediately transferring all production traffic removes the staged validation safeguard. Creating another AI gateway route version is also unnecessary for the required three-step promotion sequence.
