Question 721
To complete the sentence, select the appropriate option in the answer area.
From Azure Machine Learning designer, to deploy a real-time inference pipeline as a service for others to consume, you must deploy the model to __________.
A. a local web service.
B. Azure Container Instances.
C. Azure Kubernetes Service (AKS).
D. Azure Machine Larning compute.
Answer
C. Azure Kubernetes Service (AKS).
Explanation
To perform real-time inferencing, you must deploy a pipeline as a real-time endpoint. Real-time endpoints must be deployed to an Azure Kubernetes Service cluster.
Question 722
To complete the sentence, select the appropriate option in the answer area.
Predicting how many hours of overtime a delivery person will work based on the number of order received is an example of __________.
A. classification
B. clustering
C. regression
Answer
C. regression
Explanation
In the most basic sense, regression refers to prediction of a numeric target. Linear regression attempts to establish a linear relationship between one or more independent variables and a numeric outcome, or dependent variable. You use this module to define a linear regression method, and then train a model using a labeled dataset. The trained model can then be used to make predictions.
Incorrect Answers:
- Classification is a machine learning method that uses data to determine the category, type, or class of an item or row of data.
- Clustering, in machine learning, is a method of grouping data points into similar clusters. It is also called segmentation. Over the years, many clustering algorithms have been developed. Almost all clustering algorithms use the features of individual items to find similar items. For example, you might apply clustering to find similar people by demographics. You might use clustering with text analysis to group sentences with similar topics or sentiment.
Question 723
HOTSPOT -For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Statement 1: Azure Machine Learning designer provides a drag-and-drop visual canvas to build, test, and deploy machine learning models.
Statement 2: Azure Machine Learning designer enables you to save your progress as a pipeline draft.

Answer
Statement 1: Azure Machine Learning designer provides a drag-and-drop visual canvas to build, test, and deploy machine learning models. Yes
Statement 2: Azure Machine Learning designer enables you to save your progress as a pipeline draft. Yes
Statement 3: Azure Machine Learning designer enables you to include custom JavaScript functions. No
Explanation
Box 1: Yes -Azure Machine Learning designer lets you visually connect datasets and modules on an interactive canvas to create machine learning models.
Box 2: Yes -With the designer you can connect the modules to create a pipeline draft.As you edit a pipeline in the designer, your progress is saved as a pipeline draft.
Box 3: No –
