                                                                                            You have files that are ingested and loaded into an Azure Data Lake Storage Gen2 container named container1.
                                                                                            You plan to insert data from the files into Table1 and transform the data. Each row of data in the files will produce one row in the serving layer of Table1.
                                                                                            You need to ensure that when the source data files are loaded to container1, the DateTime is stored as an additional column in Table1.
                                                                                            Solution: You use an Azure Synapse Analytics serverless SQL pool to create an external table that has an additional DateTime column.
                                                                                            Does this meet the goal?

                                                                                            You have an on-premises server named Server1 that has Microsoft SQL Server installed. Server1 contains a database named DB1. You have an Azure subscription that contains a user named User1. You need to ensure that User1 can perform the following actions:
                                                                                            * Register a resource provider to support migrating DB1 to Azure.
                                                                                            * Create an Azure Database Migration Service instance
                                                                                            * Migrate DB1 to Azure SQL Database.
                                                                                            The solution must follow the principle of least privilege.
                                                                                            Which role should you assign to User1 for the subscription, and which resource provider should User1 register? To answer, select the appropriate options in the answer area.

                                                                                            Explanation:

                                                                                            Basic Concept: This question tests choosing the correct Azure migration approach by matching the source platform, target service, downtime tolerance, and administrative effort.
                                                                                            Why the selected answer is Correct: The selected values fit this scenario because they apply the required Azure SQL configuration at the correct scope and sequence: You need to ensure that User1 can perform the following actions: * Register a resource provider to support migrating DB1 to Azure.
                                                                                            Why the alternate choices are Wrong: The alternate selections would either use a migration tier that does not match the downtime requirement, choose a network resource that does not support the migration path, or add an unnecessary deployment component.

                                                                                            Question #5

                                                                                            You have an Azure Synapse Analytics dedicated SQL pool named Pool1 and an Azure Data Lake Storage Gen2 account named Account1.
                                                                                            You plan to access the files in Account1 by using an external table.
                                                                                            You need to create a data source in Pool1 that you can reference when you create the external table.
                                                                                            How should you complete the Transact-SQL statement? To answer, select the appropriate options in the answer area.
                                                                                            NOTE: Each correct selection is worth one point.

                                                                                            Box 1: blob

The correct choice is determined by the exact service boundary and operational requirement stated in the scenario.
                                                                                            Why the selected answer is Correct: The selected values fit this scenario because they apply the required Azure SQL configuration at the correct scope and sequence: You need to create a data source in Pool1 that you can reference when you create the external table.
                                                                                            Why the alternate choices are Wrong: The alternate selections apply to different administrative stages or different scopes. In a hotspot or drag-drop task, order and scope are part of the answer, so a technically valid Azure feature can still be wrong if it is placed in the wrong step.
