      Answer:

      Explanation: Step 1: Configure a Microsoft Data Management Gateway Install and configure Azure Data Factory Integration Runtime.
      The Integration Runtime is a customer managed data integration infrastructure used by Azure Data Factory to provide data integration capabilities across different network environments. This runtime was formerly called "Data Management Gateway".
      Step 2: Create a linked service for Azure Blob storage
      Create an Azure Storage linked service (destination/sink). You link your Azure storage account to the data factory.
      Step 3: Create a linked service for SQL Server
      Create and encrypt a SQL Server linked service (source)
      In this step, you link your on-premises SQL Server instance to the data factory. Step 4: Create an input dataset and an output dataset.
      Create a dataset for the source SQL Server database. In this step, you create input and output datasets. They represent input and output data for the copy operation, which copies data from the on-premises SQL Server database to Azure Blob storage.
      Step 5: Create a pipeline..
      You create a pipeline with a copy activity. The copy activity uses SqlServerDataset as the input dataset and AzureBlobDataset as the output dataset. The source type is set to SqlSource and the sink type is set to BlobSink.

          Your company has several thousand sensors deployed.
          You have a Microsoft Azure Stream Analytics job that receives two data streams Input1 and Input2 from an Azure event hub. The data streams are portioned by using a column named SensorName. Each sensor is identified by a field named SensorID.
          You discover that Input2 is empty occasionally and the data from Input1 is ignored during the processing of the Stream Analytics job.
          You need to ensure that the Stream Analytics job always processes the data from Input1.
          How should you modify the query? To answer, select the appropriate options in the answer area.

                70-475 dumps exhibit

                  Answer:

                  Explanation: Lambda architecture is a data-processing architecture designed to handle massive quantities of data by taking advantage of both batch- and stream-processing methods. This approach to architecture attempts to balance latency, throughput, and fault-tolerance by using batch processing to provide comprehensive and accurate views of batch data, while simultaneously using real-time stream processing to provide views of online data. The two view outputs may be joined before presentation
                  Box 1: Speed
                  The speed layer processes data streams in real time and without the requirements of fix-ups or completeness. This layer sacrifices throughput as it aims to minimize latency by providing real-time views into the most recent data.
                  Box 2: Batch
                  The batch layer precomputes results using a distributed processing system that can handle very large quantities of data. The batch layer aims at perfect accuracy by being able to process all available data when generating views.
                  Box 3: Serving
                  Output from the batch and speed layers are stored in the serving layer, which responds to ad-hoc queries by returning precomputed views or building views from the processed data.

                  You have a Microsoft Azure Data Factory pipeline.
                  You discover that the pipeline fails to execute because data is missing. You need to rerun the failure in the pipeline.
                  Which cmdlet should you use?

                  • A. Set-AzureRmAutomationJob
                  • B. Set-AzureRmDataFactorySliceStatus
                  • C. Resume-AzureRmDataFactoryPipeline
                  • D. Resume-AzureRmAutomationJob

                  Answer: B

                  Explanation: Use some PowerShell to inspect the ADF activity for the missing file error. Then simply set the dataset slice to either skipped or ready using the cmdlet to override the status.
                  For example:
                  Set-AzureRmDataFactorySliceStatus `
                  -ResourceGroupName $ResourceGroup `
                  -DataFactoryName $ADFName.DataFactoryName `

                      Answer:

                      Explanation: Box 1: Azure HDInsight MapReduce
                      Azure Event Hubs allows you to process massive amounts of data from websites, apps, and devices. The Event Hubs spout makes it easy to use Apache Storm on HDInsight to analyze this data in real time.
                      Box 2: Azure Event Hub
                      Box 3: Azure Stream Analytics
                      Stream Analytics is a new service that enables near real time complex event processing over streaming data. Combining Stream Analytics with Azure Event Hubs enables near real time processing of millions of events per second. This enables you to do things such as augment stream data with reference data and output to storage (or even output to another Azure Event Hub for additional processing).

                      NOTE: Each correct selection is worth one point.

                      • A. a Microsoft Azure SQL data warehouse
                      • B. a Microsoft Azure HDInsight Hadoop cluster
                      • C. a Microsoft SQL Server database
                      • D. a Microsoft Azure HDInsight Storm cluster
                      • E. Microsoft Azure Table Storage

                      Answer: AE

                      Explanation: A: Azure SQL Data Warehouse is a SQL-based, fully-managed, petabyte-scale cloud data warehouse. It’s highly elastic, and it enables you to set up in minutes and scale capacity in seconds. Scale compute and storage independently, which allows you to burst compute for complex analytical workloads, or scale down your warehouse for archival scenarios, and pay based on what you're using instead of being locked into predefined cluster configurations—and get more cost efficiency versus traditional data warehouse solutions.
                      E: Use Azure Table storage to store petabytes of semi-structured data and keep costs down. Unlike many data stores—on-premises or cloud-based—Table storage lets you scale up without having to manually shard your dataset. Perform OData-based queries.
