  You need to connect to an AKS node by using SSH.

  Solution: You add an SSH key to the node, and then you create an SSH connection.

  Does this meet the goal?

  A. Yes

  B. No

  Correct Answer: A

  By default, SSH keys are generated when you create an AKS cluster. If you did not specify your own SSH keys when you created your AKS cluster, add your public SSH keys to the AKS nodes. You also need to create an SSH connection to the AKS node.

• Question 64:

  You are developing a Computer Vision application.

  You plan to use a workflow that will load data from an on-premises database to Azure Blob storage, and then connect to an Azure Machine Learning service.

  What should you use to orchestrate the workflow?

  A. Azure Kubernetes Service (AKS)

  B. Azure Pipelines

  C. Azure Data Factory

  D. Azure Container Instances

  Correct Answer: C

  With Azure Data Factory you can use workflows to orchestrate data integration and data transformation processes at scale. Build data integration, and easily transform and integrate big data processing and machine learning with the visual interface.

• Question 65:

  Your company has a data team of Transact-SQL experts.

  You plan to ingest data from multiple sources into Azure Event Hubs.

  You need to recommend which technology the data team should use to move and query data from Event Hubs to Azure Storage. The solution must leverage the data team's existing skills.

  What is the best recommendation to achieve the goal? More than one answer choice may achieve the goal.

  A. Azure Notification Hubs

  B. Azure Event Grid

  C. Apache Kafka streams

  D. Azure Stream Analytics

  Correct Answer: D

  Azure Stream Analytics is a real-time analytics and complex event processing engine that is well-suited for ingesting, processing, and storing data from various sources, including Azure Event Hubs. It provides a familiar SQL-like language (Transact-SQL) for querying and transforming data, making it a suitable choice for a data team of Transact-SQL experts. With Azure Stream Analytics, the data team can easily define queries and transformations to move and query data from Event Hubs to Azure Storage.

• Question 66:

  You plan to design a solution for an AI implementation that uses data from IoT devices.

  You need to recommend a data storage solution for the IoT devices that meets the following requirements:

  1.

  Allow data to be queried in real-time as it streams into the solution.

  2.

  Provide the lowest amount of latency for loading data into the solution. What should you include in the recommendation?

  A. a Microsoft Azure Table Storage solution

  B. a Microsoft Azure HDInsight R Server cluster

  C. a Microsoft Azure HDInsight Hadoop cluster

  D. a Microsoft Azure SQL database that has In-Memory OLTP enabled

  Correct Answer: C

  You can use HDInsight to process streaming data that's received in real time from a variety of devices.

  Internet of Things (IoT)

  You can use HDInsight to build applications that extract critical insights from data. You can also use Azure Machine Learning on top of that to predict future trends for your business.

  By combining enterprise-scale R analytics software with the power of Apache Hadoop and Apache Spark, Microsoft R Server for HDInsight gives you the scale and performance you need. Multi-threaded math libraries and transparent

  parallelization in R Server handle up to 1000x more data and up to 50x faster speeds than open-source R, which helps you to train more accurate models for better predictions.

• Question 67:

  Your company has factories in 10 countries. Each factory contains several thousand IoT devices.

  The devices present status and trending data on a dashboard.

  You need to ingest the data from the IoT devices into a data warehouse.

  Which two Microsoft Azure technologies should you use? Each correct answer presents part of the solution.

  NOTE: Each correct selection is worth one point.

  A. Azure Stream Analytics

  B. Azure Data Factory

  C. an Azure HDInsight cluster

  D. Azure Batch

  E. Azure Data Lake

  Correct Answer: CE

  With Azure Data Lake Store (ADLS) serving as the hyper-scale storage layer and HDInsight serving as the Hadoop-based compute engine services. It can be used for prepping large amounts of data for insertion into a Data Warehouse

• Question 68:

  You plan to deploy two AI applications named AI1 and AI2. The data for the applications will be stored in a relational database.

  You need to ensure that the users of AI1 and AI2 can see only data in each user's respective geographic region. The solution must be enforced at the database level by using row-level security.

  Which database solution should you use to store the application data?

  A. Microsoft SQL Server on a Microsoft Azure virtual machine

  B. Microsoft Azure Database for MySQL

  C. Microsoft Azure Data Lake Store

  D. Microsoft Azure Cosmos DB

  Correct Answer: A

  Row-level security is supported by SQL Server, Azure SQL Database, and Azure SQL Data Warehouse.

  References: https://docs.microsoft.com/en-us/sql/relational-databases/security/row-level-security?view=sql-server-2017

• Question 69:

  You are designing an AI workflow that will aggregate data stored in Azure as JSON documents.

  You expect to store more than 2 TB of new data daily.

  You need to choose the data storage service for the data. The solution must minimize costs.

  Which data storage service should you choose?

  A. Azure Manage Disks

  B. Azure Blob Storage

  C. Azure File Storage

  D. Azure Data Lake Storage

  Correct Answer: B

  Generally, Data Lake will be a bit more expensive although they are in close range of each other. Blob storage has more options for pricing depending upon things like how frequently you need to access your data (cold vs hot storage). Data Lake is priced on volume, so it will go up as you reach certain tiers of volume.
