You have an Exchange Server 2010 organization. The organization contains a Mailbox server named
Server1. Server1 hosts two mailbox databases and one public folder database. You plan to deploy a
new Mailbox server named Server2. You need to recommend a high-availability solution for Server1
that meets the following requirements:
• Mailboxes and public folders must be available if a single Mailbox server fails
• Deploy the minimum number of servers
What should you recommend?

A.
Install fallover clustering on both servers, and then configure cluster continuous replication.
Replicate all public folders to Server2.

B.
Create and configure a database availability group (DAG).
Add Server1 and Server2 to the DAG. Create database copies.
Replicate all public folders to Server2.

C.
Create and configure a database availability group (DAG).
Add Server1 and Server2 to the DAG. Deploy a new server named Server3.
Create database copies.
Configure Server3 as a dedicated public folder server.

D.
Install fallover Clustering on both servers, and then configure a single copy cluster (SCC).
Deploy a new server named Server3.
Configure Server3 as a dedicated public folder server.

Explanation:

This question really only talks about one server so I am not sure where server 2 enters the picture. In
order to have to a high availability you will need a second server – which in that case B is the correct
answer.
