Question 101

You are creating a machine learning model. You have a dataset that contains null rows.
You need to use the Clean Missing Data module in Azure Machine Learning Studio to identify and resolve the null and missing data in the dataset.
Which parameter should you use?

    You are using Azure Machine Learning to run an experiment that trains a classification model.
    You want to use Hyperdrive to find parameters that optimize the AUC metric for the model. You configure a HyperDriveConfig for the experiment by running the following code:

    You plan to use this configuration to run a script that trains a random forest model and then tests it with validation data. The label values for the validation data are stored in a variable named y_test variable, and the predicted probabilities from the model are stored in a variable named y_predicted.
    Solution: Run the following code:

    Does the solution meet the goal?
  • Question 103

    You need to correct the model fit issue.
    Which three 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.

    Question 104

    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.

    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: Install the Azure ML SDK on the Surface Book. Run Python code to connect to the workspace and then run the training script as an experiment on local compute.
    Does the solution meet the goal?
  • Question 105

    You use Data Science Virtual Machines (DSVMs) for Windows and Linux in Azure.
    You need to access the DSVMs.
    Which utilities should you use? To answer, select the appropriate options in the answer area.
    NOTE: Each correct selection is worth one point.
