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?

A.
On each of the servers, add Domain1 Sales Global and Domain2 Sales Global to Sales Applications Local.

B.
In Domain1, create a universal security group named Sales Department Universal. Add Domain1 Sales Global and Domain2 Sales Global to Sales Department Universal.
On each of the servers, add Sales Department Universal group to Sales Applications Local.

C.
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.
On each of the servers, assign permissions to Sales Applications Domain Local from the local domain.

D.
Create two universal security groups named Domain1\Sales Department Universal and Domain2\Sales Department Universal.
Add Domain1\Domain1 Sales Global to Domain1\Sales Department Universal. Add Domain2\Domain2 Sales Global to Domain2\Sales Department Universal.
On each of the servers, add Domain1\Sales Department Universal and Domain2\Sales Department Universal to Sales Applications Local.
