You need to ensure that sales department users can create site collections. You run the following Windows PowerShell commands: $w.SelfServiceSiteCreationEnabled =$True $w.Update() Does the solution me

The $w variable references an SPWebApplication object. Setting SelfServiceSiteCreationEnabled to $True on that object and calling Update() persists the change to the configuration database, enabling self-service site collection creation for users scoped to that web application. This is the correct PowerShell approach to enable this feature at the web application level.

Incorrect because both commands are valid - SelfServiceSiteCreationEnabled is a legitimate SPWebApplication property and Update() correctly commits the change to the SharePoint configuration database.
