Your company’s security policy states that all of the servers deployed to a branch office must not have the graphical user interface (GUI) installed. In a branch
office, a support technician installs a server with a GUI installation of windows Server 2016 on a new server, and then configures the server as a DHCP server.
You need to ensure that the new server meets the security policy. You want to achieve this goal by using the minimum amount of Administrative effort.
What should you do?
A.
Reinstall windows Server 2016 on the server.
B.
From Windows PowerShell, run Uninstall-WindowsFeature Desktop-Experience.
C.
From Windows PowerShell, run Uninstall-WindowsFeature PowerShell-ISE.
D.
From Server Manager, uninstall the User Interfaces and Infrastructure feature.
not with Windows Server 2016, that option is not possible, you need to reinstall
