The first action is to register the model in the Azure Machine Learning workspace . Microsoft’s documented no-code workflow for generating Responsible AI insights in Azure Machine Learning studio explicitly starts by registering the model. After registration, you navigate to Models , select the registered model, and choose Create Responsible AI dashboard .

The scenario already specifies an MLflow-formatted regression model using tabular data , which aligns with the Responsible AI dashboard’s supported model architecture. Microsoft states that models used by the Responsible AI components must be registered in Azure Machine Learning in MLflow format with an sklearn flavor , and the associated datasets must use supported tabular formats such as MLTable.

Option B is incorrect because model explanations are an optional dashboard component configured after selecting the registered model; they are not the prerequisite first step. Option C is unnecessary and counterproductive because MLflow is a supported format. Option D is also unnecessary: a Responsible AI dashboard evaluates a registered model and does not require deployment to a managed online endpoint first. Microsoft also describes Responsible AI dashboards as being linked directly to registered models in the model registry.

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.

In Azure ML command jobs, MLflow automatically creates a run context, so explicit start_run is optional. The training script must call mlflow.log_param to record each hyperparameter for the run. If the script calls this for each hyperparameter, the requirement for capturing parameters per run is met. The script must also call mlflow.log_metric to record numeric metrics such as accuracy or loss, optionally indexed by training step. Metrics and parameters logged inside an Azure ML command job are automatically associated with the correct experiment and run — no manual specification of experiment or run ID is required. If all three elements (run context, parameter logging, metric logging) are present in the script, all experiment tracking statements are True. If any element is absent, the corresponding statement is False and the tracking requirement is not met.

Dictionary of key value properties for the Model. These properties cannot be changed after registration, however new key value pairs can be added.

The team cannot rely on live user traffic for evaluation because it would make results non-reproducible and could expose users to untested prompts. Synthetic data generation within Microsoft Foundry allows the team to produce diverse, representative input examples that simulate real user queries without any live traffic risk, giving a stable, consistent test set evaluated under identical conditions. Option B (content filters) and Option C (blocklists) are safety controls applied at inference time, not evaluation inputs. Option D (observability metrics) is a monitoring capability for production systems. With synthetic data, the team can construct edge cases, varied phrasings, and domain-specific scenarios that would take months to accumulate organically from real users, directly enabling the controlled evaluation the question requires without any dependency on live traffic.

A Git repository provides all three capabilities required: version history for every change with author attribution and timestamp, branching for experimentation, tagging for stable releases, and a single source of truth accessible to all projects via clone or submodule reference. Azure ML datasets (option B) are designed for training data, not text configuration artifacts, and lack per-line diff tracking and review workflows. Embedding prompts in application configuration files (option C) scatters prompt content across multiple applications with no unified view, no shared versioning, and no cross-project reuse. Unstructured Blob Storage with folder organization (option D) provides no version history, no diff tracking, no review workflow, and no native tooling for comparing prompt variants. Git is the definitive answer for centralized tracking, versioning, and reuse of prompt content across Microsoft Foundry projects.
