Which tool should you use?

Your network contains an Active Directory domain named contoso.com. All domain
controllers run Windows Server 2012 R2.
An organizational unit (OU) named OU1 contains 200 client computers that run Windows 8
Enterprise. A Group Policy object (GPO) named GPO1 is linked to OU1.
You make a change to GPO1.
You need to force all of the computers in OU1 to refresh their Group Policy settings
immediately. The solution must minimize administrative effort.
Which tool should you use?

A.
The Secedit command

B.
Group Policy Management Console (GPMC)

C.
Server Manager

D.
The Gpupdate command

Explanation:
In the previous versions of Windows, this was accomplished by having the user run
GPUpdate.exe on their computer.
Starting with Windows Server® 2012 and Windows® 8, you can now remotely refresh Group
Policy settings for all computers in an OU from one central location through the Group Policy
Management Console (GPMC). Or you can use the Invoke-GPUpdatecmdlet to refresh

Group Policy for a set of computers, not limited to the OU structure, for example, if the
computers are located in the default computers container.
