                                              168. Frage
                                              You have an Azure Data Factory pipeline that performs an incremental load of source data to an Azure Data Lake Storage Gen2 account.
                                              Data to be loaded is identified by a column named LastUpdatedDate in the source table.
                                              You plan to execute the pipeline every four hours.
                                              You need to ensure that the pipeline execution meets the following requirements:
                                              * Automatically retries the execution when the pipeline run fails due to concurrency or throttling limits.
                                              * Supports backfilling existing data in the table.
                                              Which type of trigger should you use?

                                              Antwort: B

                                              Begründung:
                                              Section: [none]
                                              Explanation:
                                              The Tumbling window trigger supports backfill scenarios. Pipeline runs can be scheduled for windows in the past.
                                              Incorrect Answers:
                                              D: Schedule trigger does not support backfill scenarios. Pipeline runs can be executed only on time periods from the current time and the future.

                                              DRAG DROP
                                              Your company analyzes images from security cameras and sends alerts to security teams that respond to unusual activity. The solution uses Azure Databricks.
                                              You need to send Apache Spark level events, Spark Structured Streaming metrics, and application metrics to Azure Monitor.
                                              Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions in the answer area and arrange them in the correct order.

                                              Section: [none]
                                              Explanation:
                                              Send application metrics using Dropwizard.
                                              Spark uses a configurable metrics system based on the Dropwizard Metrics Library.
                                              To send application metrics from Azure Databricks application code to Azure Monitor, follow these steps:
                                              Step 1: Configure your Azure Databricks cluster to use the Databricksmonitoring library.
                                              Prerequisite: Configure your Azure Databricks cluster to use the monitoring library.
                                              Step 2: Build the spark-listeners-loganalytics-1.0-SNAPSHOT.jar JAR file Step 3: Create Dropwizard counters in your application code Create Dropwizard gauges or counters in your application code

                                              Hotspot Question
                                              You have an Azure subscription that contains an instance of SQL Server on Azure Virtual Machines named SQLVM1 and a user named User1. SQLVM1 hosts a database named DB1.
                                              You need to ensure that User1 can perform the following tasks on DB1:
                                              - Create jobs.
                                              - View all jobs.
                                              - Modify, delete, and disable the jobs the user created.
                                              The solution must use the principle of least privilege.
                                              Which built-in database role should you assign to User1, and where is the role defined? To answer, select the appropriate options in the answer area.

                                              SIMULATION
                                              You need to configure differential backups for the db1 Azure SQL database to be once a day instead of twice day.
                                              You may need to use SQL Server Management Studio and the Azure portal.

                                              Antwort:

                                              Begründung:

                                              To change the PITR backup retention period or the differential backup frequency for active databases by using the Azure portal:
                                              Step 1: Go to the logical server in Azure with the databases whose retention period you want to change.
                                              Step 2: Select Backups on the left pane, and then select the Retention policies tab.
                                              Step 3: Select the databases for which you want to change the PITR backup retention. [Select db1] Step 4: Select Configure policies from the action bar.
                                              Step 5: To change the retention period for point-in-time restore backups, use the slider under Point-in-time restore.
                                              Step 6: To change differential backup frequency, select 12 Hours or 24 hours from the drop- down menu under Differential backup frequency . [Select 12 hours]
