Question 61

You are retrieving data from a large datastore by using Azure Machine Learning Studio. You must create a subset of the data for testing purposes using a random sampling seed based on the system clock. You add the Partition and Sample module to your experiment. You need to select the properties for the module. Which values should you select? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. Hot Area:

Question 62

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?

  1. Replace with mean
  2. Remove entire column
  3. Remove entire row
  4. Hot Deck
  5. Custom substitution value
  6. Replace with mode

Question 63

The finance team asks you to train a model using data in an Azure Storage blob container named finance-data. You need to register the container as a datastore in an Azure Machine Learning workspace and ensure that an error will be raised if the container does not exist. How should you complete the code? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. Hot Area:

Question 64

You plan to provision an Azure Machine Learning Basic edition workspace for a data science project. You need to identify the tasks you will be able to perform in the workspace. Which three tasks will you be able to perform? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

  1. Create a Compute Instance and use it to run code in Jupyter notebooks.
  2. Create an Azure Kubernetes Service (AKS) inference cluster.
  3. Use the designer to train a model by dragging and dropping pre-defined modules.
  4. Create a tabular dataset that supports versioning.
  5. Use the Automated Machine Learning user interface to train a model.

Question 65

A coworker registers a datastore in a Machine Learning services workspace by using the following code: You need to write code to access the datastore from a notebook. 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. Hot Area:
