Exchange 2010 is being implemented on a pair of VNX storage arrays. There will be a production
site and a DR site, each with two servers and one VNX storage array. EMC RecoverPoint will
handle the remote replication between the sites.
Which is a valid architecture?

A.
Implement both Exchange servers in a local DAG. Install EMC Replication Enabler for
Exchange (REE) and install Replication Manager agents on all severs in the DAG.

B.
Implement both Exchange servers in a cluster with shared disks. Use separate LUNs and RAID
Groups for the Database, Log and Quorum. Install and enable EMC Replication Manager for
remote replication.

C.
Implement both Exchange servers in a local DAG. Install EMC Replication Manager for remote
replication.

D.
Implement both Exchange servers in a cluster with shared disks. Use separate LUNs and RAID
Groups for the Database, Log and Quorum. Install and enable Microsoft Cluster Enabler for
RecoverPoint to enable cluster failover between sites.
