Your company has a single-domain Active Directory Domain Services (AD DS) forest named contoso.com. The forest contains one domain controller named DC1 in the main office.
You plan to deploy a second writeable domain controller named DC2 to a branch office.
You need to configure a deployment option that will minimize initial network bandwidth usage between the main office and the branch office.
Which option should you modify during the deployment of DC2?
- the database location
- the Global Catalog (GC) option
- the Install from media option
- This answer is correct.
- the SYSVOL location
- the Install from media option
Given the answer choices, the only one which affects the bandwidth used during the deployment of an additional domain controller to a single-domain forest is the Install from media option. In this scenario, to significantly reduce the amount of traffic over a WAN link, you create an AD DS backup from DC1 and transfer the backup (typically offline via removable media) to the remote location. When you are at the remote location, during domain controller promotion, you select the Install from media option. This way, a majority of the database and SYSVOL content is copied locally from the backup media. The WAN link transfers only security-related traffic and changes to AD DS that took place following the backup. Clearing the option to configure the domain controller as a global catalog can have an impact in a multi-domain forest, but not in a single-domain forest. The SYSVOL and AD DS database are always local to the domain controller, so their location is irrelevant to network bandwidth utilization.
