You have a server named Server1 that runs a Server Core installation of Windows Server 2012 R2 Standard.
You establish a Remote Desktop session to Server1.
You need to identify which task can be performed on Server1 from within the Remote Desktop session.
What should you identify?

A.
Install a feature by using Server Manager.

B.
Modify the network settings by using Sconfig.

C.
Disable services by using Msconfig.

D.

Explanation:
In Windows Server 2012 R2, you can use the Server Configuration tool (Sconfig.cmd) to configure and manage
several common aspects of Server Core installations. You must be a member of the Administrators group to
use the tool. Sconfig.cmd is available in the Minimal Server Interface and in Server with a GUI mode.
