You are a messaging professional. Your company uses a Microsoft Exchange Server 2007 messaging system.

The company purchases two new Exchange Server 2007 computers.

The new computers must meet the following Service Level Agreement (SLA) requirements:

The mailbox data is resilient.
The computers tolerate single-disk failures without service disruption.
The computers provide the maximum database I/O performance.

You need to plan a storage group layout to meet the SLA requirements.

Which set of actions should you include in the plan?

A.
Configure Local Continuous Replication (LCR). Place the transaction log directory for each storage group
and the database files for each mailbox store on separate RAID 5 volumes.

B.
Configure Local Continuous Replication (LCR). Place the transaction log directory for each storage group
and the database files for each mailbox store on separate RAID 10 volumes.

C.
Configure a two-node Single Copy Cluster (SCC) cluster. Place the transaction log directory for each
storage group and the database files for each mailbox store on separate RAID 0 volumes.

D.
Configure a two-node Single Copy Cluster (SCC) cluster. Place the transaction log directory for each
storage group and the database files for each mailbox store on separate RAID 10 volumes.
