You are a messaging professional. Your company uses a Microsoft Exchange
Server 2007 messaging solution.

The company has deployed a single Microsoft Active Directory domain. An organizational unit named
ExchangeServers is configured in the domain. ExchangeServers contains two child organizational units
named HTServers and MboxServers. HTServers contains the computer accounts for the Hub Transport
servers and MboxServers contains the computer accounts for the Mailbox servers.

The Edge Transport servers are stand-alone computers that are part of a workgroup named Edge.

You need to ensure that all e-mail messages sent between the Hub Transport server and the Edge
Transport server are encrypted by using IPSec. You want to achieve this goal without disrupting message
delivery.

Which two tasks should you perform? (Each correct answer presents part of the solution. Choose two.)

A.
Assign the IPSec Server policy to HTServers. Configure IPSec authentication to use the appropriate
authentication.

B.
Assign the IPSec Server policy to MboxServers. Configure IPSec authentication to use the appropriate
authentication.

C.
Assign the IPSec Secure Server policy to HTServers. Configure IPSec authentication to use the appropriate
authentication.

D.
Assign the IPSec Server policy to each Edge Transport server by using the Local Security Policy. Configure
IPSec authentication to use the appropriate authentication.

E.
Assign the IPSec Secure Server policy to each Edge Transport server by using the Local Security Policy.
Configure IPSec authentication to use the appropriate authentication.
