Your network consists of a single Active Directory domain. All domain controllers run Windows Server 2008 R2.
There are five servers that run Windows Server 2003 SP2. The Windows Server 2003 SP2 servers have the Terminal Server component installed. A firewall server runs Microsoft Internet Security and Acceleration (ISA) Server 2006. All client computers run Windows 7.
You plan to give remote users access to the Remote Desktop Services servers.
You need to create a remote access strategy for the Remote Desktop Services servers that meets the following requirements:
Minimizes the number of open ports on the firewall server.
Encrypts all remote connections to the Remote Desktop Services servers.
Prevents network access to client computers that have Windows Firewall disabled.
What should you do?
A. Implement port forwarding on the ISA Server. Implement Network Access Quarantine Control on the ISA Server.
B. 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 implement Network Access Protection (NAP).
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 connection authorization policy (RD CAP).
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 resource authorization policy (RD RAP).
