HOTSPOT
Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
You have an initial dataset that contains the crime data from major cities.
You plan to build training models from the training dat
a. You plan to automate the process of adding more data to the training models and to constantly tune the models by using the additional data, including data that is collected in near real-time. The system will be used to analyze event data gathered from many different sources, such as Internet of Things (IoT) devices, live video surveillance, and traffic activities, and to generate predictions of an increased crime risk at a particular time and place.
You have an incoming data stream from Twitter and an incoming data stream from Facebook, which are event-based only, rather than time-based. You also have a time interval stream every 10 seconds.
The data is in a key/value pair format. The value field represents a number that defines how many times a hashtag occurs within a Facebook post, or how many times a Tweet that contains a specific hashtag is retweeted.
You must use the appropriate data storage, stream analytics techniques, and Azure HDInsight cluster types for the various tasks associated to the processing pipeline.
You are using Microsoft Power BI Desktop to create visualizations of the crime data predictions. You connect to a JSON file that is stored in Azure Blob storage.
After loading the data into Power BI, the query shows the following metadata fields only:
Name
Content
Extension
Date created
Date accessed
Date modified
The actual columns have the following names:
Duration
Zip Code
Start Time
Probability
Crime Type
Likelihood Percent
You need to transform the query so that Power BI can access the actual columns rather than the metadata.
Which two actions should you perform from the Edit Queries menu on the Home ribbon? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
You have several Linux-based and Windows-based Azure HDInsight clusters. The clusters are indifferent Active Directory domains.
You need to consolidate system logging for all of the clusters into a single location. The solution must provide near real-time analytics of the log dat a.
What should you use?
You have an Azure HDInsight cluster.
You need a build a solution to ingest real-time streaming data into a nonrelational distributed database.
What should you use to build the solution?
Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
You need to deploy an HDInsight cluster to perform real-time event processing. The cluster server must be managed by using Remote Desktop.
What should you do?
DRAG DROP
You have an Apache HBase cluster in Azure HDInsight. The cluster has a table named sales that contains a column family named customerfamily.
You need to add a new column family named customeraddr to the sales table.
How should you complete the command? To answer, drag the appropriate values to the correct targets.
Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
