A corporate environment includes a main office and a branch office. The company plans to deploy Exchange Server 2010. The Mailbox servers will be part of a single database availability group (DAG) that spans both locations. There is only intermittent connectivity between the two locations. You need to recommend a public folder database solution that enables users from either location to consistently access public folders.

Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

A.
Configure cross-site RPC Client Access on the DAG

B.
Configure public folder referrals between the main office and the branch office.

C.
Create a single public folder database in the main office and add it as a replica for the public folders.

D.
Create a single public folder database in the branch office and add it as a replica for the public folders.
