Your company has an Active Directory Domain Services (AD DS) domain. All servers run Windows
Server 2008 R2. All client computers run Windows 7. You have a Remote Desktop Session Host (RD
Session Host) server and a Remote Desktop Gateway (RD Gateway) server. You change the
configuration of Windows Firewall by using Group Policy. Users on the corporate network are then
unable to connect to their virtual desktops. You need to ensure that users can connect to their
virtual desktops. What should you do? (Each correct answer presents part of the solutions. Choose
two.)

A.
Create a Windows Firewall inbound rule for port 443 on the RD Gateway server.

B.
Create a Windows Firewall inbound rule for port 443 on the RD Session Host server.

C.
Create a Windows Firewall inbound rule for port 3389 on the RD Gateway server.

D.
Create a Windows Firewall inbound rule for port 3389 on the RD Session Host server.

Explanation:
An RD Gateway server uses port 443, which transmits data through a Secure Sockets Layer (SSL)
tunnel. http://windows.microsoft.com/en-us/windows7/What-is-a-Remote-Desktop-Gateway-server
