Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have a table named Table1 that contains 3 billion rows. Table1 contains data from the last 36 months.
At the end of every month, the oldest month of data is removed based on a column named DateTime.
You need to minimize how long it takes to remove the oldest month of data.
Solution: You specify DateTime as the hash distribution column.
Does this meet the goal?

You need to use the Cognition.Vision.FaceDetector() function in U-SQL to analyze images.
Which attribute can you detect by using the function?

You need to copy data from Microsoft Azure SQL Database to Azure Data Lake Store by using Azure Data Factory.
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.

You have a Microsoft Azure Data Lake Analytics service and an Azure Data Lake Store.
You need to use Python to submit a U-SQL job.
Which Python module should you install?

You plan to use Microsoft Azure Event Hubs in Azure Stream Analytics to consume time-series aggregations from several published data sources, such as IoT data, reference data, and social media.
You expect several TB of data to be consumed daily. All the consumed data will be retained for one week.
You need to recommend a storage solution for the data. The solution must minimize costs.
What should you recommend?

You have IoT devices that produce the following output.

You need to use Microsoft Azure Stream Analytics to convert the output into the tabular format described in the following table.

How should you complete the Stream Analytics query? 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.

Note: This question is part of a series of questions that present 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.
Start of repeated scenario
You are migrating an existing on-premises data warehouse named LocalDW to Microsoft Azure. You will use an Azure SQL data warehouse named AzureDW for data storage and an Azure Data Factory named AzureDF for extract, transformation, and load (ETL) functions.
For each table in LocalDW, you create a table in AzureDW.
On the on-premises network, you have a Data Management Gateway.
Some source data is stored in Azure Blob storage. Some source data is stored on an on-premises Microsoft SQL Server instance. The instance has a table named Table1.
After data is processed by using AzureDF, the data must be archived and accessible forever. The archived data must meet a Service Level Agreement (SLA) for availability of 99 percent. If an Azure region fails, the archived data must be available for reading always. The storage solution for the archived data must minimize costs.
End of repeated scenario.
You need to configure an activity to move data from blob storage to AzureDW.
What should you create?

You plan to use Microsoft Azure Event Hubs to ingest data. You plan to use Azure Stream Analytics to analyze the data in real time and to send the output directly to Azure Data Lake Store.
You discover duplicate records in the output data.
What is a possible cause of the duplicate records?

You plan to capture the output from a group of 500 IoT devices that produce approximately 10 GB of data per hour by using Microsoft Azure Stream Analytics. The data will be retained for one year.
Once the data is processed, it will be stored in Azure, and then analyzed by using an Azure HDInsight cluster.
You need to select where to store the output data from Stream Analytics. The solution must minimize costs.
What should you select?
