Writing data in a Table using HBase Shell
You are building an Azure Stream Analytics pipeline. You need to configure the pipeline to analyze events that occur during a five-minute window after an event fires. Which windowing function should you use?
You create an Azure Stream Analytics job. You run the job for five hours. You need to ensure that these events are not dropped. What should you do?
You design an Azure Data Factory data flow activity to move large amounts of data from text files to an Azure Synapse Analytics database. You add a data flow script to your data flow. The data flow in the designer has the following tasks: distinctRows1: Aggregate data by using myCols that produce columns. source1: Import data from DelimitedText1. derivedColumn1: Create and update the C1 columns. select1: Rename derivedColumn1 as select1 with columns C1. sink1: Add a sink dataset. You need to ensure that all the rows in source1 are deduplicated. What should you do?
You have 500 IoT devices and an Azure subscription. You plan to build a data pipeline that will process real-time data from the devices. You need to ensure that the devices can send messages to the subscription. What should you deploy?
You have a Delta Lake solution that contains a table named table1. You need to roll back the contents of table1 to 24 hours ago. Which command should you run?
You have an Azure Data Factory pipeline named Pipeline1. Which two types of triggers can you use to start Pipeline1 directly? Each correct answer presents a complete solution.
You have an Azure Data Factory pipeline named Pipeline1. You need to send an email message if Pipeline1 fails. What should you do?
