Your network consists of three Active Directory forests. Forest trust relationships exist between all forests. Each forest contains one domain. All domain controllers run Windows Server 2008 R2. Your company has three network administrators. Each network administrator manages a forest and the Group Policy objects （GPOs） within that forest.   You need to create standard GPOs that the network administrators in each forest will use. The GPOs must meet the following requirements：   èThe GPOs must only contain settings for either user configurations or computer configurations. èThe number of GPOs must be minimized.   Which two actions should you perform？（）

• A、Export the new GPOs to .cab files. Ensure that the .cab files are available to the network administrator  in each forest.
• B、Create two new GPOs. Configure both GPOs to use the required user configurations and the required  computer configurations.
• C、Create two new GPOs. Configure one GPO to use the required user configuration. Configure the other GPO to use the required computer configuration.
• D、Back up the Sysvol folder that is located on the domain controller where the new GPOs were created. Provide the backup to the network administrator in each forest.
