You are a SharePoint administrator for Contoso, Ltd. The company acquires WingTip Toys. You must be able to manage and administer SharePoint site collections in the WingTip Toys SharePoint farm by…

Adding WingTip administrators to Site Collection Administrators grants SharePoint UI-level access to site collections, not the SQL-level permissions required to run Windows PowerShell cmdlets remotely.

Site Collection Administrators is a SharePoint permission group controlling UI access to site collections, not the backend database-level access required for PowerShell administration of a farm.

The SharePoint_Shell_Access role is a SQL Server database role that grants the minimum permissions needed to execute SharePoint Windows PowerShell cmdlets against a farm. Contoso administrators need this role on the WingTip farm because they are the ones performing the remote administration tasks. Without this role, PowerShell cmdlets will fail with access-denied errors regardless of SharePoint-level permissions.

WingTip administrators do not need the SharePoint_Shell_Access role; the Contoso administrators who are performing the remote management tasks are the ones who require this role on the WingTip farm.
