You have an Exchange Server 2003 organization. All users connect to their mailboxes by using Microsoft Office Outlook. You start to transition the organization to new Exchange Server 2010 servers. The new servers are on a secured subnet that is separated by a firewall. You will move half of the mailboxes to the new servers. Client Access servers and Mailbox servers are on the secured subnet. Client computers on the network can access the Client Access servers. You need to recommend a solution that allows users to connect to Public Folders by using Outlook or Outlook Web App (OWA).

What should you include in the solution?

A.
Public Folder referrals and forms-based authentication

B.
Public Folder referrals and HTTP connections to the Mailbox servers

C.
Public Folder replicas and MAPI connections to the Mailbox servers

D.
Public Folder replicas and WebReady Document Viewing
