How can you ensure that only Sales desktop computers receive the GPO?

You work as a Network Administrator at AIOTestking.com. AIOTestking.com has an Active Directory
Domain Services (AD DS) domain named AIOTestking.com. All servers in the AIOTestking.com domain
have Microsoft Windows Server 2012 R2 installed.
AIOTestking.com has a Sales department and a Research department. An organizational unit (OU)
exists for each department. The OUs contain the user and computer accounts for the respective
departments.
The client computers are a mix of portable laptop computers and desktop computers. All client
computers have Windows 7 Professional installed.
You configure a group policy object (GPO) named SalesDesktops. You link the GPO to the Sales
OU.
You need to ensure that the SalesDesktops GPO applies to only the desktop computers in the
Sales department. Your solution should ensure that any new desktop computers added to the
Sales OU also receive the SalesDesktops GPO.
