• Question 2:

  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.

  End of repeated scenario.

  You need to configure an activity to move data from blob storage to AzureDW.

  What should you create?

  A. a pipeline
  B. a linked service
  C. an automation runbook
  D. a dataset
  A. a pipeline

• Question 3:

  You have sensor devices that report data to Microsoft Azure Stream Analytics. Each sensor reports data several times per second.

  You need to create a live dashboard in Microsoft Power BI that shows the performance of the sensor devices. The solution must minimize lag when visualizing the data.

  Which function should you use for the time-series data element?

  A. LAG
  B. SlidingWindow
  C. System.TimeStamp
  D. TumblingWindow
  D. TumblingWindow

• Question 4:

  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 define the schema of Table1 in AzureDF.

  What should you create?

  A. a gateway
  B. a linked service
  C. a dataset
  D. a pipeline
  C. a dataset

• Question 5:

  You have a Microsoft Azure SQL data warehouse that has 10 compute nodes.

  You need to export 10 TB of data from a data warehouse table to several new flat files in Azure Blob storage. The solution must maximize the use of the available compute nodes. What should you do?

  A. Use the bcp utility.
  B. Execute the CREATE EXTERNAL TABLE AS SELECT statement.
  C. Create a Microsoft SQL Server Integration Services (SSIS) package that has a data flow task.
  D. Create a Microsoft SQL Server Integration Services (SSIS) package that has an SSIS Azure Blob Storage task.
  D. Create a Microsoft SQL Server Integration Services (SSIS) package that has an SSIS Azure Blob Storage task.

• Question 6:

  You have a fact table named PowerUsage that has 10 billion rows. PowerUsage contains data about customer power usage during the last 12 months. The usage data is collected every minute. PowerUsage contains the columns configured as shown in the following table.

  

  LocationNumber has a default value of 1. The MinuteOfMonth column contains the relative minute within each month. The value resets at the beginning of each month. A sample of the fact table data is shown in the following table.

  

  There is a related table named Customer that joins to the PowerUsage table on the CustomerId column. Sixty percent of the rows in PowerUsage are associated to less than 10 percent of the rows in Customer. Most queries do not require the

  use of the Customer table. Many queries select on a specific month.

  You need to minimize how long it takes to find the records for a specific month.

  What should you do?

  A. Implement partitioning by using the MonthKey column. Implement hash distribution by using the CustomerId column.
  B. Implement partitioning by using the CustomerId column. Implement hash distribution by using the MonthKey column.
  C. Implement partitioning by using the MonthKey column. Implement hash distribution by using the MeasurementId column.
  D. Implement partitioning by using the MinuteOfMonth column. Implement hash distribution by using the MeasurementId column.
  C. Implement partitioning by using the MonthKey column. Implement hash distribution by using the MeasurementId column.

• Question 7:

  You have a Microsoft Azure Data Lake Analytics service. You need to provide a user with the ability to monitor Data Lake Analytics jobs. The solution must minimize the number of permissions assigned to the user. Which role should you assign to the user?

  A. Reader
  B. Owner
  C. Contributor
  D. Data Lake Analytics Developer
  A. Reader

• Question 8:

  HOTSPOT

  You use Microsoft Visual Studio to develop custom solutions for customers who use Microsoft Azure Data Lake Analytics.

  You install the Data Lake Tools for Visual Studio.

  You need to identify which tasks can be performed from Visual Studio and which tasks can be performed from the Azure portal.

  What should you identify for each task? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.

  Hot Area:

  

  

• Question 9:

  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 are monitoring user queries to a Microsoft Azure SQL data warehouse that has six compute nodes.

  You discover that compute node utilization is uneven. The rows_processed column from sys.dm_pdw_workers shows a significant variation in the number of rows being moved among the distributions for the same table for the same query.

  You need to ensure that the load is distributed evenly across the compute nodes.

  Solution: You add a nonclustered columnstore index.

  Does this meet the goal?

  A. Yes
  B. No
  B. No

• Question 10:

  You are using Cognitive capabilities in U-SQL to analyze images that contain different types of objects.

  Which two reference assemblies should you use? Each correct answer presents part of the solution.

  NOTE: Each correct selection is worth one point.

  A. ExtPython
  B. ImageCommon
  C. ImageTagging
  D. ExtR
  E. FaceSdk
