Your network consists of a single Active Directory domain. All domain controllers run Windows
Server 2008 R2. There are five Windows Server 2003 SP2 servers that have the Terminal Server
component installed. A firewall server runs Microsoft Internet Security and Acceleration (ISA) Server
2006. You need to create a remote access strategy for the Remote Desktop Services servers that
meets the following requirements:
• Restricts access to specific users
• Minimizes the number of open ports on the firewall
• Encrypts all remote connections to the Remote Desktop Services servers
What should you do?
A.
Implement SSL bridging on the ISA Server. Require authentication on all inbound connections to
the ISA Server.
B.
Implement port forwarding on the ISA Server. Require authentication on all inbound connections
to the ISA Server.
C.
Upgrade a Windows Server 2003 SP2 server to Windows Server 2008 R2. On the Windows Server
2008 R2 server, implement the Remote Desktop Gateway (RD Gateway) role service, and configure a
Remote Desktop resource authorization policy (RD RAP).
D.
Upgrade a Windows Server 2003 SP2 server to Windows Server 2008 R2. On the Windows Server
2008 R2 server, implement the Remote Desktop Gateway (RD Gateway) role service, and configure a
Remote Desktop connection authorization policy (RD CAP).

MCITP Self-Paced Training Kit Exam 70-646 Windows Server Administration:
Terminal Services Gateway TS Gateway allows Internet clients secure, encrypted access to Terminal
Servers behind your organization’s firewall without having to deploy a Virtual Private Network (VPN)
solution. This means that you can have users interacting with their corporate desktop or applications
from the comfort of their homes without the problems that occur when VPNs are configured to run
over multiple Network Address Translation (NAT) gateways and the firewalls of multiple vendors.
TS Gateway works using RDP over Secure Hypertext Transfer Protocol (HTTPS), which is the same
protocol used by Microsoft Office Outlook 2007 to access corporate Exchange Server 2007 Client
Access Servers over the Internet. TS Gateway Servers can be configured with connection
authorization policies and resource authorization policies as a way of differentiating access to
Terminal Servers and network resources.
Connection authorization policies allow access based on a set of conditions specified by the
administrator; resource authorization policies grant access to specific Terminal Server resources
based on user account properties.
Connection Authorization Policies
Terminal Services connection authorization policies (TS-CAPs) specify which users are allowed to
connect through the TS Gateway Server to resources located on your organization’s internal
network. This is usually done by specifying a local group on the TS Gateway Server or a group within
Active Directory. Groups can include user or computer accounts. You can also use TS-CAPs to specify
whether remote clients use password or smart-card authentication to access internal network
resources through the TS Gateway Server. You can use TS-CAPs in conjunction with NAP; this
scenario is covered in more detail by the next lesson.
