• Question 12:

  Note: This question is part of a series of questions that use 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.

  You have an initial dataset that contains the crime data from major cities.

  You plan to build training models from the training data. You plan to automate the process of adding more data to the training models and to constantly tune the models by using the additional data, including data that is collected in near real-

  time. The system will be used to analyze event data gathered from many different sources, such as Internet of Things (IoT) devices, live video surveillance, and traffic activities, and to generate predictions of an increased crime risk at a

  particular time and place.

  You have an incoming data stream from Twitter and an incoming data stream from Facebook, which are event-based only, rather than time-based. You also have a time interval stream every 10 seconds.

  The data is in a key/value pair format. The value field represents a number that defines how many times a hashtag occurs within a Facebook post, or how many times a Tweet that contains a specific hashtag is retweeted.

  You must use the appropriate data storage, stream analytics techniques, and Azure HDInsight cluster types for the various tasks associated to the processing pipeline.

  You are designing the real-time portion of the input stream processing. The input will be a continuous stream of data and each record will be processed one at a time. The data will come from an Apache Kafka producer.

  You need to identify which HDInsight cluster to use for the final processing of the input data. This will be used to generate continuous statistics and real-time analytics. The latency to process each record must be less than one millisecond and

  tasks must be performed in parallel.

  Which type of cluster should you identify?

  A. Apache Storm
  B. Apache Hadoop
  C. Apache HBase
  D. Apache Spark
  A. Apache Storm

• Question 14:

  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 sections, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

  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 new topics. Create a file import process to send messages. Start the consumer and run the producer. Does this meet the goal?

  A. Yes
  B. No
  A. Yes

• Question 15:

  Note: This question is part of a series of questions that use 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.

  You are planning a big data infrastructure by using an Apache Spark cluster in Azure HDInsight. The cluster has 24 processor cores and 512 GB of memory.

  The architecture of the infrastructure is shown in the exhibit. (Click the Exhibit button.)

  

  The architecture will be used by the following users:

  The data sources in the batch layer share a common storage container. The following data sources are used:

  You need to ensure that the support analysts can develop embedded analytics applications by using the least amount of development effort.

  Which technology should you implement?

  A. Zeppelin
  B. Jupyter
  C. Apache Ambari
  D. Livy
  D. Livy

  The architecture will be used by the following users:

  The data sources in the batch layer share a common storage container. The following data sources are used:

  The business analysts require queries to monitor the sales data. The queries must be faster and more interactive than the batch layer queries.

  You need to create a new infrastructure to support the queries. The solution must ensure that you can tune the cache policies of the queries.

  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.

• Question 17:

  DRAG DROP

  You have a domain-joined Azure HDInsight cluster.

  You plan to assign permissions to several support staff.

  You need to assign roles to the staff so that they can perform specific tasks. The solution must use the principle of least privilege.

  Which role should you assign for each task? To answer, drag the appropriate roles to the correct targets. Each role 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.
