• Question 63:

  HOTSPOT

  You create an Azure Machine Learning workspace named workspace1. You assign a custom role to a user of workspace1.

  The custom role has the following JSON definition:

  

  Instructions: For each of the following statements, select Yes if the statement is true. Otherwise, select No.

  NOTE: Each correct selection is worth one point.

  Hot Area:

  

  Correct Answer:

  

  Box 1: No

  The actions listed in NotActions are prohibited.

  If the roles include Actions that have a wildcard (*), the effective permissions are computed by subtracting the NotActions from the allowed Actions.

  Box 2: No

  Deleting compute resources in the workspace is in the NotActions list.

  Box 3: Yes

  Writing metrics is not listed in NotActions.

• Question 64:

  HOTSPOT

  You are the owner of an Azure Machine Learning workspace.

  You must prevent the creation or deletion of compute resources by using a custom role. You must allow all other operations inside the workspace.

  You need to configure the custom role.

  How should you complete the configuration? To answer, select the appropriate options in the answer area.

  Correct Answer:

  

  Box 1: Microsoft.MachineLearningServices/workspaces/*/read

  Reader role: Read-only actions in the workspace. Readers can list and view assets, including datastore credentials, in a workspace. Readers can't create or update these assets.

  Box 2: Microsoft.MachineLearningServices/workspaces/*/write

  If the roles include Actions that have a wildcard (*), the effective permissions are computed by subtracting the NotActions from the allowed Actions.

• Question 65:

  HOTSPOT

  You create a Python script named train.py and save it in a folder named scripts. The script uses the scikit-learn framework to train a machine learning model.

  You must run the script as an Azure Machine Learning experiment on your local workstation.

  You need to write Python code to initiate an experiment that runs the train.py script.

  How should you complete the code segment? To answer, select the appropriate options in the answer area.

  Correct Answer:

  

  Box 1: source_directory

  source_directory: A local directory containing code files needed for a run.

  Box 2: script

  Script: The file path relative to the source_directory of the script to be run.

  Box 3: environment

• Question 66:

  HOTSPOT

  You are using an Azure Machine Learning workspace. You set up an environment for model testing and an environment for production.

  The compute target for testing must minimize cost and deployment efforts. The compute target for production must provide fast response time, autoscaling of the deployed service, and support real-time inferencing.

  You need to configure compute targets for model testing and production.

  Which compute targets should you use? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.

  Hot Area:

  

  Correct Answer:

  

  Box 1: Local web service

  The Local web service compute target is used for testing/debugging. Use it for limited testing and troubleshooting. Hardware acceleration depends on use of libraries in the local system.

  Box 2: Azure Kubernetes Service (AKS)

  Azure Kubernetes Service (AKS) is used for Real-time inference.

  Recommended for production workloads.

  Use it for high-scale production deployments. Provides fast response time and autoscaling of the deployed service

  HOTSPOT

  Complete the sentence by selecting the correct option in the answer area.

  Hot Area:

  

  Correct Answer:

  

  Replace using Probabilistic PCA: Compared to other options, such as Multiple Imputation using Chained Equations (MICE), this option has the advantage of not requiring the application of predictors for each column. Instead, it approximates the covariance for the full dataset. Therefore, it might offer better performance for datasets that have missing values in many columns.

• Question 69:

  HOTSPOT

  You use an Azure Machine Learning workspace.

  You create the following Python code:

  

  For each of the following statements, select Yes if the statement is true. Otherwise, select No.

  NOTE: Each correct selection is worth one point.

  Hot Area:

  

  Correct Answer:

  

  Box 1: No

  Environment is a required parameter. The environment to use for the run. If no environment is specified, azureml.core.runconfig.DEFAULT_CPU_IMAGE will be used as the Docker image for the run.

  The following example shows how to instantiate a new environment. from azureml.core import Environment myenv = Environment(name="myenv")

  Box 2: Yes

  Parameter compute_target: The compute target where training will happen. This can either be a ComputeTarget object, the name of an existing ComputeTarget, or the string "local". If no compute target is specified, your local machine will be

  used.

  Box 3: Yes

  Parameter source_directory. A local directory containing code files needed for a run.

  Parameter script. The file path relative to the source_directory of the script to be run.
