You are a messaging professional.
Your company has four offices. Each office has a perimeter network. The perimeter network includes a wireless access point that allows access for employees and guest users. The perimeter network is created between two Microsoft Windows Server 2003 computers that run Microsoft Internet Security and Acceleration (ISA) Server 2006.
Each office has an Edge Transport server on the perimeter network, and a Hub Transport server, a Client Access server, and a Mailbox server on the internal network. One office has a member server that runs Internet Authentication Service (IAS).
Employees who connect to the wireless access points are not able to receive e-mail messages from the nearest Exchange server.
You need to ensure that all employee computers that are connected to the wireless access points can retrieve e-mail messages in the most secure manner. You also need to ensure that guest computers can access the perimeter network by connecting to the wireless access point.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution.
Choose two.)
A.
Configure the wireless access point as a RADIUS client and activate TKIP-PSK security.
B.
Configure the internal ISA Server 2006 computer in each office to publish RPC over HTTPS services on the
Client Access Server.
C.
Configure the external ISA Server 2006 computer in each office to publish RPC over HTTPS services on
the Edge Transport server.
D.
Configure the internal ISA Server 2006 computer in each office as a RADIUS client and configure each
wireless client computer to establish a VPN connection to the nearest ISA Server 2006 computer.
E.
Configure the external ISA Server 2006 computer in each office as a RADIUS client and configure each
wireless client computer to establish a VPN connection to the nearest ISA Server 2006 computer.
