You are the messaging engineer for your company. Your company has two offices. One office is located in Tokyo and the other office is located in New York. Both offices are connected to the Internet.

In each office, you deploy an Exchange Server 2007 Edge Transport server and a Hub Transport server.
Both Edge Transport servers receive e-mail from the Internet.
