Question 12

Answer D is correct. You can programmatically map linked server logins by using the sp_addlinkedsrvlogin procedure. sp_helplogins provides information about logins and users but does nothing to create or map users. sp_addlogin can be used to add logins to the local instance. sp_adduser adds a login to a database. sp_grantlogin creates a SQL Server login on a local instance.
