How can you automate the promotion of the server using the settings in the TK-RODC1.txt file?

You work as a Network Administrator at AIOTestking.com. AIOTestking.com has an Active Directory
Domain Services (AD DS) domain named AIOTestking.com. All domain controllers in the AIOTestking.com
domain have either Windows Server 2008 R2 Service Pack 1 (SP1) or Windows Server 2012 R2
installed.
You plan to create a Windows Server 2012 R2 Read Only Domain Controller in the AIOTestking.com
domain.
You open Active Directory Users and Computers and select the Pre-create a read-only domain
controller account option. You go through the Welcome to the Active Directory Domain Services
Installation Wizard and specify the settings to create an account named TK-RODC1. You use the
Export Settings option to export the settings to a file named TK-RODC1.txt. You plan to use this
text file to automate the installation of the Read Only Domain Controller.
You install a Window Server 2012 R2 Server.
