Question 61

You are building an experiment using the Azure Machine Learning designer.
You split a dataset into training and testing sets. You select the Two-Class Boosted Decision Tree as the algorithm.
You need to determine the Area Under the Curve (AUC) of the model.
Which three modules should you use in sequence? To answer, move the appropriate modules from the list of modules to the answer area and arrange them in the correct order.

Question 62

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
An IT department creates the following Azure resource groups and resources:

The IT department creates an Azure Kubernetes Service (AKS)-based inference compute target named aks-cluster in the Azure Machine Learning workspace.
You have a Microsoft Surface Book computer with a GPU. Python 3.6 and Visual Studio Code are installed.
You need to run a script that trains a deep neural network (DNN) model and logs the loss and accuracy metrics.
Solution: Attach the mlvm virtual machine as a compute target in the Azure Machine Learning workspace.
Install the Azure ML SDK on the Surface Book and run Python code to connect to the workspace. Run the training script as an experiment on the mlvm remote compute resource.
  • Question 63

    You have a Python data frame named salesData in the following format:

    The data frame must be unpivoted to a long data format as follows:

    You need to use the pandas.melt() function in Python to perform the transformation.
    How should you complete the code segment? To answer, select the appropriate options in the answer area.
    NOTE: Each correct selection is worth one point.

    Question 64

    You have a model with a large difference between the training and validation error values.
    You must create a new model and perform cross-validation.
    You need to identify a parameter set for the new model using Azure Machine Learning Studio.
    Which module you should use for each step? To answer, drag the appropriate modules to the correct steps.
    Each module may be used once or more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
    NOTE: Each correct selection is worth one point.

    Question 65

    You publish a batch inferencing pipeline that will be used by a business application.
    The application developers need to know which information should be submitted to and returned by the REST interface for the published pipeline.
    You need to identify the information required in the REST request and returned as a response from the published pipeline.
    Which values should you use in the REST request and to expect in the response? To answer, select the appropriate options in the answer area.
    NOTE: Each correct selection is worth one point.
