You are a messaging professional. Your company runs a Microsoft

Exchange Server 2007 messaging system.

The company has deployed a single Microsoft Active Directory domain with three Active Directory sites,

in New York City (NYC), Los Angeles (LA), and Tokyo, Japan.

The Exchange Server 2007 organization includes six Exchange Server 2007 computers on each site. The

Exchange organization is managed by administrators in LA.

The companys sites are connected to one another by using two dedicated T3 WAN links; NYC to LA and

LA to Tokyo. Each site has an Internet connection.

The Tokyo location includes an Internet application that is mission critical. The only network traffic that

is allowed on the Internet connection in Tokyo is traffic related to this application.

You are planning to implement a Microsoft Windows Server Update Services (WSUS) server on each site

to update the Exchange Server 2007 computers. Only administrators in LA will approve all updates for

the Exchange Server 2007 computers.

You need to design the WSUS implementation to update the Exchange Server 2007 computers on each

site. You also need to minimize the bandwidth consumption for updates on WAN links and Internet

connections.

How should you design the Exchange update hierarchy to design the WSUS implementation to update the Exchange Server 2007 computers?
