Question 169

DRAG DROP - You are developing a machine learning solution by using the Azure Machine Learning designer. You need to create a web service that applications can use to submit data feature values and retrieve a predicted label. 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 170

You are implementing hyperparameter tuning for a model training from a notebook. The notebook is in an Azure Machine Learning workspace. You must configure a grid sampling method over the search space for the num_hidden_layers and batch_size hyperparameters. You need to identify the hyperparameters for the grid sampling. Which hyperparameter sampling approach should you use?

Question 171

HOTSPOT - You load data from a notebook in an Azure Machine Learning workspace into a pandas dataframe. The data contains 10,000 records. Each record consists of 10 columns. You must identify the number of missing values in each of the columns. You need to complete the Python code that will return the number of missing values in each of the columns. Which code segments should you use? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Question 172

HOTSPOT - You manage an Azure Machine Learning workspace. You create a training script named sample_training_script.py. The script is used to train a predictive model in the conda environment defined by a file named environment.yml. You need to run the script as an experiment. How should you complete the following code segment? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Question 173

HOTSPOT - You have an Azure Machine Learning workspace. You need to use the Azure Machine Learning SDK for Python to create and register the Azure Data Lake Storage Generation 2 datastore for the workspace. How should you complete the following code segment? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Question 174

You have an Azure Machine Learning workspace. You are connecting an Azure Data Lake Storage Gen2 account to the workspace as a data store. You need to authorize access from the workspace to the Azure Data Lake Storage Gen2 account. What should you use?

Question 175

DRAG DROP - You provision an Azure Machine Learning workspace in a new Azure subscription. You need to attach Azure Databricks as a compute resource from the Azure Machine Learning workspace. Which four 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 176

You create an Azure Machine Learning workspace. You must configure an event handler to send an email notification when data drift is detected in the workspace datasets. You must minimize development efforts. You need to configure an Azure service to send the notification. Which Azure service should you use?

Question 177

You are creating a compute target to train a machine learning experiment. The compute target must support automated machine learning, machine learning pipelines, and Azure Machine Learning designer training. You need to configure the compute target. Which option should you use?

Question 178

HOTSPOT - You create an Azure Data Lake Storage Gen2 storage account named storage1containing a file system named fs1 and a folder named folder1. The contents of folder1 must be accessible from jobs on compute targets in the Azure Machine Learning workspace. You need to construct a URI to reference folder1. How should you construct the URI? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
