In an Azure Machine Learning environment, you are deploying two models using a blue/green deployment strategy and wish to direct a specific percentage of traffic to each model. Using the Azure Machine Learning Python SDK, how would you configure the endpoint to route 70% of the traffic to the 'blue' model and 30% to the 'green' model? Choose the correct code snippet from the options below, assuming the endpoint object is already defined.

B- endpoint.traffic = {"blue": 70, "green": 30}; ml_client.begin_create_or_update(endpoint).result()

You're developing a machine learning model in an Azure Notebook and need to load data from a CSV file into a pandas DataFrame. The file, 'source_data.csv', is located in the same directory as your Python script 'MyMLScript.py'. What is the correct way to load this data into a DataFrame at the beginning of your script?

A- source_data = pd.read_csv('source_data.csv')

In a simple regression model training pipeline built using Azure Machine Learning studio Designer, which step is considered optional?

B- Excluding irrelevant columns from the loaded data.

In Python, when working with pandas DataFrames, you often encounter columns with null or missing values. If you need to replace these null values in a numerical column of a DataFrame with a specific numerical value, which line of code is the correct approach?

A- my_dataframe.fillna( value={"Claim Amount": 0.01}, inplace=True)

In the context of converting notebooks to production-ready scripts in Azure Machine Learning, Microsoft recommends refactoring large, monolithic code blocks into smaller functions. What are the primary benefits of this practice? (Choose 2)

B- To facilitate easier testing of the code; C- To improve code readability and maintainability

In the context of Azure Automated Machine Learning (AutoML), how can a user influence the outcomes and performance despite AutoML's automation features? (Choose 2)

A- Exclude specific algorithms to tailor AutoML's algorithm selection process.; D- Choose the primary performance metric for the model evaluation.
