Question
You need to copy data in bulk from Azure SQL Database to Azure SQL Data Warehouse, using Azure PowerShell. You first create a data factory with the name “QuickStart” by running the Set-AzDataFactoryV2 cmdlet but get the following error message: “The specified Data Factory name ‘QuickStart’ is already in use.” Which of the following describes what you must do to successfully create a data factory?
A. The database name needs to be replaced with values of your Azure SQL Database before running the command.
B. The name of the Azure data factory is case sensitive, so you must resubmit the data with no uppercase lettering.
C. The servername needs to be replaced with values of your Azure SQL Database before running the command.
D. The name of the Azure data factory must be globally unique, so you must change the name and run the command again.
Answer
To successfully create an Azure Data Factory when encountering the error message “The specified Data Factory name ‘QuickStart’ is already in use,” you must ensure that the name of your data factory is globally unique. This error occurs because Azure enforces a naming rule where each data factory name must be unique across all Azure subscriptions. Here’s how to resolve the issue:
D. The name of the Azure data factory must be globally unique, so you must change the name and run the command again.
Explanation
Global Uniqueness Requirement
Azure Data Factory names are case-insensitive and must be unique across all subscriptions in Microsoft Azure. For example, “QuickStart” cannot be reused if it is already taken by another user or project anywhere in Azure.
Steps to Resolve
Modify the $dataFactoryName variable in your PowerShell script to a new, globally unique name. For instance, instead of “QuickStart”, use a name like “QuickStartFactory123” or append random alphanumeric characters to ensure uniqueness.
Example Command
$dataFactoryName = "QuickStartFactory123" $DataFactory = Set-AzDataFactoryV2 -ResourceGroupName $ResGrp.ResourceGroupName -Location $ResGrp.Location -Name $dataFactoryName Rerun the command after updating the name.
Why Other Options Are Incorrect
Option A: Replacing the database name is irrelevant because this error pertains to the data factory’s global naming rules, not database configuration.
Option B: While names are case-insensitive, changing uppercase letters does not address uniqueness across subscriptions.
Option C: Replacing server names pertains to database connectivity and does not resolve a data factory naming conflict.
By ensuring your data factory name is globally unique, you will successfully create it and proceed with your pipeline setup for copying data from Azure SQL Database to Azure SQL Data Warehouse.
