What should you use?

Your network contains an Active Directory domain named contoso.com. The domain contains more than 100 Group Policy objects (GPOs). Currently, there are no enforced GPOs. The domain is renamed to adatum.com. Group Policies no longer function correctly. You need to ensure that the existing GPOs are applied to users and computers. You want to achieve this goal by using the minimum amount of administrative effort.

A . Dcgpofix
B . Get-GPOReport
C . Gpfixup
D . Gpresult
E . Gpedit. msc
F . Import-GPO
G . Restore-GPO
H . Set-GPInheritance

Answer: C

Explanation:

You can use the gpfixup command-line tool to fix the dependencies that Group Policy objects (GPOs) and Group Policy links in Active Directory Domain Services (AD DS) have on Domain Name System (DNS) and NetBIOS names after a domain rename operation.
