B.
Use Round-robin DNS

C.
Use Terminal Services Gateway (TS Gateway)

D.
Use Network Load Balancing (NLB)

E.
None of the above

Explanation:

To create a Terminal Services server farm with given requirements, you need to use Terminal Services Session Broker (TS Session Broker).
Terminal Services Session Broker (TSSession Broker) is a role service in WindowsServer�2008 that enables a user to reconnect to an existing session in a load-balanced terminal server farm. Additionally, Windows Server2008 includes the new TSSession Broker Load Balancing feature. This feature enables you to distribute the session load between servers in a load-balanced terminal server farm.
TSSession Broker stores session state information that includes session IDs and their associated user names, and the name of the server where each session resides. In the second phase, the terminal server where the initial connection was made redirects the user to the terminal server that was specified by TSSession Broker. The redirection behavior is as follows:
A user with an existing session will connect to the server where their session exists. A user without an existing session will connect to the terminal server that has the fewest sessions.
