which server should you do this?

You are the systems administrator for your company. You install Windows Essential Business Server (EBS) 2008 Premium Edition on the network. You migrate from Exchange Server 2003 to the Messaging Server. You want to modify some settings for the edge transport role.

On which server should you do this?

A.
Management Server

B.
Security Server

C.
Messaging Server

D.
Database Server

Explanation:
You should modify the settings for the edge transport role on the Security Server. An Exchange Server 2007 organization contains five roles: the client access role, edge transport role, hub transport role, mailbox role, and unified messaging role. Of these five roles, the Messaging Server runs the client access, hub transport, and mailbox roles, while the Security Server runs the edge transport role. The unified messaging role is not available in Windows EBS 2008.

The options stating Management Server, Messaging Server, and Database Server are incorrect because the edge transport role is installed on the Security Server.
