You have an Apache Hive cluster in Microsoft Azure HDInsight. The cluster contains 10 million data files.
You plan to archive the data.
The data will be analyzed monthly.
You need to recommend a solution to move and store the data. The solution must minimize how long it takes to move the data and must minimize costs.
Which two services should you include in the recommendation? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

• A.Azure Queue storage
• B.Azure Data Factory
• C.Microsoft SQL Server Integration Services (SSIS)
• D.Azure Table Storage
• E.Azure Data Lake

You have a Microsoft Azure Data Factory that loads data to an analytics solution.
You receive an alert that an error occurred during the last processing of a data stream.
You debug the problem and solve an error.
You need to process the data stream that caused the error.
What should you do?

• A.From Azure Cloud Shell, run the az batch job enable command.
• B.From Azure Cloud Shell, run the az dla job command.
• C.From PowerShell, run the Resume-AzureRmDataFactoryPipeline cmdlet.
• D.From PowerShell, run the Set-AzureRmDataFactorySliceStatus cmdlet.

You need to configure the alert to meet the requirements for ETL.
Which settings should you use for the alert? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Explanation

Scenario: Relecloud identifies the following requirements for extract, transformation, and load (ETL): An email alert must be generated when a failure of any type occurs during ETL processing.

You have a web app that accepts user input, and then uses a Microsoft Azure Machine Learning model to predict a characteristic of the user.
You need to perform the following operations:
* Track the number of web app users from month to month.
* Track the number of successful predictions made during the last minute.
* Create a dashboard showcasing the analytics tor the predictions and the web app usage.
Which lambda layer should you query for each operation? To answer, drag the appropriate layers to the correct operations. Each layer 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.

정답:

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 manage a Microsoft Azure HDInsight Hadoop cluster. All of the data for the cluster is stored in Azure Premium Storage.
You need to prevent all users from accessing the data directly. The solution must allow only the HDInsight service to access the data.
Which five 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.

정답:

Explanation
1. Create Shared Access Signature policy2. Save the SAS policy token, storage account name, and container name. These values are used when associating the storage account with your HDInsight cluster.3. Update property of core-site4. Maintenance mode5.
