Your network consists of one Active Directory forest that contains two domains named Domain1.contoso.com and Domain2.contoso.com. The functional level of the forest is Windows Server 2003. The domains contain the global security groups shown in the following table. Each domain has three servers. Each server has a group named Sales-Applications-Local. The Sales-Applications-Local groups are used to grant permissions to resources on the servers. You need to implement a solution to meet the following requirements: Allow Sales department employees from any domain to access the Sales department resources in any domain. Minimize administrative effort when membership of the Sales department changes, additional domains are added,or additional servers are added. What should you do? （）

• B、·On each of the servers, add Sales-Department-Universal group to Sales-Applications-Local. ·In each domain, create a domain local security group named Sales-Applications-Domain-Local. ·In each domain, add Domain1-Sales-Global and Domain2-Sales-Global to Sales-Applications-Domain-Local.
• C、·On each of the servers, assign permissions to Sales-Applications-Domain-Local from the local domain. ·Create two universal security groups named Domain1/Sales-Department-Universal andDomain2/Sales-Department-Universal. ·Add Domain1/Domain1-Sales-Global to Domain1/Sales-Department-Universal. ·Add Domain2/Domain2-Sales-Global to Domain2/Sales-Department-Universal.
