You have an Azure Storage account named storage1.

In Azure Role-Based Access Control (RBAC), the Storage Account Key Operator Service Role allows a user to list and regenerate access keys for a storage account but does not grant permission to access the data itself.

The Storage Account Key Operator Service Role has the following key permissions:

Microsoft.Storage/storageAccounts/listkeys/action

Microsoft.Storage/storageAccounts/regeneratekey/action

Microsoft.Storage/storageAccounts/read

This role is typically used by automation or service accounts that need to manage storage account keys without having full access to the data stored within the account (blobs, files, queues, etc.).

In the scenario, User1 only needs to list and regenerate storage account keys for storage1, not perform data operations or modify configurations. The Storage Account Key Operator Service Role provides precisely these permissions, making it the correct and minimal-privilege choice for this task.

Thus, assigning this role to User1 meets the goal as per Azure RBAC guidelines and Microsoft’s least privilege principle documented in the Azure Administrator exam guide.
