Your network contains two Active Directory forests named contoso.com and adatum.com. All domain controllers run Windows Server 2012. The adatum.com
domain contains a Group Policy object (GPO) named GPO1. An administrator from adatum.com backs up GPO1 to a USB flash drive. You have a domain
controller named dc1.contoso.com. You insert the USB flash drive in dc1.contoso.com. You need to identify the domain-specific reference in GPO1. What should
you do?
A.
From Group Policy Management, run the Group Policy Results Wizard.
B.
From the Migration Table Editor, click Populate from GPO.
C.
From Group Policy Management, run the Group Policy Modeling Wizard.
D.
From the Migration Table Editor, click Populate from Backup.
A migration table is used when you copy or import a Group Policy object (GPO) from one domain or forest to another. The key challenge when migrating Group Policy objects (GPOs) from one domain or forest to another is that some information in the GPO is actually specific to the domain or forest where the GPO is defined. When transferring the GPO to a new domain or forest, it may not always be desirable, or even possible, to use the same settings. You can use a migration table to reference users, groups, computers, and UNC paths in the source GPO to new values in the destination GPO
