You are a messaging professional. Your company uses a Microsoft Exchange Server 2007 messaging system.
Your company has a single office. You deploy a Client Access Server, a Hub Transport server, and two Mailbox servers. A total of 1,000 mailboxes are located on the two Mailbox servers.
Your company acquires another company that has four offices located across the U.S. Each office has 250 users. The Wide Area Network (WAN) links are installed from each acquired branch office to the main office.
All the users from the acquired company are provided a Microsoft Active Directory user account and a mailbox in the parent company’s Exchange organization. All users in the branch offices use Microsoft Outlook 2002.
The users in the acquired company frequently report that the access to the Exchange Server 2007 computers is slow and that the messaging system is unavailable.
You need to resolve this issue for the users in the acquired company. Your solution must minimize network usage on the WAN.
What should you do?
A.
Deploy an Active Directory global catalog server and Exchange Server 2007 computers in each new branch
office.
B.
Deploy a new Client Access Server in the main office. Instruct the remote users to use Microsoft Outlook
Web Access to access their mailboxes.
C.
Deploy Microsoft Office Outlook 2007 on all the client computers in the branch offices. Configure all the
client computers to use the Exchange Cached Mode.
D.
Deploy a Microsoft Internet Security and Acceleration Server (ISA) 2006 server in each office. Configure
caching on each ISA Server 2006 computer. Configure a hub-and-spoke, site-to-site Virtual Private Network
(VPN) topology between all the branch offices and the main office.
