Explanation

This question tests knowledge of Azure App Service backup configuration, specifically how to set up scheduled backups and exclude specific folders from those backups.

Approach. To configure a daily (scheduled) backup of an Azure App Service, you must first create an Azure Storage Account (and a container within it) because App Service backups require a storage account as the destination. To exclude Folder2 from the backup, you use a file named '_backup.filter' placed in the wwwroot directory of the app - this is a special text file where you list the paths of folders or files to be excluded from the backup. The _backup.filter file should contain the path to Folder2 (e.g., \site\wwwroot\Folder2), and Azure App Service will honor these exclusions during the backup process. So: first create a Storage Account (with a Blob container), and use the _backup.filter file to exclude Folder2.

Concept tested. Azure App Service backup configuration - specifically the prerequisite of a Storage Account for scheduled backups and the use of the _backup.filter file to exclude specific directories from App Service backups.

Reference. https://docs.microsoft.com/en-us/azure/app-service/manage-backup - Azure App Service backup and restore documentation, which describes the _backup.filter file for exclusions and the requirement for an Azure Storage Account.
