You have the authority to create both Windows accounts and SQL logins and roles on your network. You have a Windows server that contains a shared folder called Administration and a shared folder called Marketing. On your SQL Sever database you have database called Marketing. Ten of your users will be working on a short-term project together; all of them require the same access to the Marketing database on the SQL Server and the Marketing folder on the Windows server, but only four of them are allowed access to the Administration folder on the Windows server. Choose the best way to grant these users access to the database resources.
(Because the users do not need access to the same resources on the Windows servers, you have no reason to create a Windows group for them. And because there are so few users here, it is easiest to create user accounts for each user and add them to a custom database role.)
