1. Note: This question is part of a series of questions that present the same Scenario. Each question I 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 correct solution.

You are building a security tracking solution in Apache Kafka to parse Security logs. The Security logs record an entry each time a user attempts to access an application. Each log entry contains the IP address used to make the attempt and the country from which the attempt originated.

You need to receive notifications when an IP address from outside of the United States is used to access the application.

Solution: Create two new brokers. Create a file import process to send messages. Run the producer.

Does this meet the goal?

5. 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.

6. You have an Azure HDlnsight cluster.

You need to build a solution to ingest real-time streaming data into nonrelational distributed database.

What should you use to build the solution?

7. You have on Apache Hive table that contains one billion rows.

You plan to use queries that will filter the data by using the WHERE clause. The values of the columns will be known only while the data loads into a Hive table.

You need to decrease the query runtime.

What should you configure?

8. You plan to copy data from Azure Blob storage to an Azure SQL database by using Azure Data factory. Which file formats can you use?

9. You have an Apache Spark cluster in Azure HDInsight.

You plan to join a large table and a lookup table.

You need to minimize data transfers during the join operation.

What should you do?

10. DRAG DROP

You have an Apache Hive cluster in Azure HDInsight. You need to tune a Hive query to meet the following requirements:

• Use the Tez engine.

• Process 1,024 rows in a batch.

How should you complete this query? To answer, drag the appropriate values to the correct targets.

11. You have an Apache Spark cluster in Azure HDInsight. You execute the following command,

%spark

import org.aache.spark.sql.hive.orc._

import org.apcahe.spark.sql._

What is the result of running the command?

12. You use YARN to manage the resources for a Spark Thrift Server running on a Linux based Apache Spark cluster in Azure HDInsight. You discover that the cluster does not fully utilize the resources. You want to increase resource allocation. You need to increase the number of executors and the allocation of memory to the Spark Thrift Server driver.

Which two parameters should you modify? Each correct answer presents part of the solution NOTE: Each correct selection is worth one point.

13. DRAG DROP

You have a text file named Data/examples/product.txt that contains product information.

You need to create a new Apache Hive table, import the product information to the table, and then read the top 100 rows of the table.

Which four code segments should you use in sequence? To answer, move the appropriate code segments from the list of code segments to the answer area and arrange them in the correct order.

14. You are configuring the Hive views on an Azure HDInsight cluster that is configured to use Kerberos.

You plan to use the YARN loos to troubleshoot a query that runs against Apache Hadoop. You need to view the method, the service, and the authenticated account used to run the query. Which method call should you view in the YARN logs?
