You are a messaging professional. Your company runs a Microsoft

Exchange Server 2007 messaging system.

The Exchange Server 2007 messaging system has three Mailbox servers named MB1, MB2, and MB3.

The messaging system also has a single Client Access Server named CAS1. All the mailbox databases and

transaction log files are stored on separate RAID 10 arrays. Each mailbox database is in a separate

storage group. MB1 contains the mailboxes of all managers in the company.

Recently, MB1 experienced a motherboard failure and was out of service for 24 hours.

You need to implement a solution to ensure that managers can access their mailboxes in the future in

spite of these types of failures.

What should you do to implement a solution to ensure that managers can access their mailboxes in the future?

A.
Enable Local Continuous Replication for the storage group that contains the managers mailboxes.

B.
Deploy a new Exchange Server 2007 Mailbox server named MB4. Move half of the managers mailboxes
from MB1 to MB4.

C.
Deploy an Exchange Server 2007 clustered Mailbox server named MBC on a Single Copy Cluster. Move all
mailboxes from MB1 to MBC. Add a host record for MBC in Domain Name System (DNS).

D.
Deploy a Client Access Server named CAS2. Create a new Network Load Balancing cluster named CAS
that has CAS1 and CAS2 as members. Add a host record for CAS in Domain Name System (DNS).
