You are the Exchange administrator for your company. All network computers are member of a single Active Directory domain.

The company has one branch office, which is connected to the main office by a WAN connection.
Each office has its own intranet. Network characteristics are shown in the following table.

The sales department is located in the main office. An Exchange Server 2003 computer named Exch3 contains all mailboxes for users in this department.

Currently, company users do not have public folders. The sales department purchases a custom application that is based on Exchange public folders.

Another administrator creates a new public folder for sales department users and installs the custom application in the public folder.

Three weeks later, you discover that the WAN connection and the intranets have high volumes of network traffic associated with public folder replication.

You need to reduce the replication traffic as much as possible, without affecting the ability of sales users to access the custom application in Microsoft Outlook.

What should you do?

A.
Configure public folder replication to use low priority replication.

B.
Remove the public folder replicas from all Exchange servers except Exch3.

C.
Make the sales public folder available only on Exch3 and and on one Exchange server in the branch office.

D.
Remove the custom application from the sales public folder. Create a new Exchange server in the main office and place the new server in a new Exchange organization. Install the application on the new server.

Explanation:
The question deals with the high volume of replication traffic.
To reduce the traffic, you need to reduce the amount of replication traffic generated. The sales department is located in the main office. An Exchange Server 2003 computer named Exch3 contains all mailboxes for users in sales department. There are no users of sale department in regional office, therefore, we can remove the public folder replicas.
