Explanation
CCR is non-existent in Exchange 2010 so the only viable solution is D. With Exchange 2010, we no longer have the concept of Local Continuous Replication (LCR), Single Copy Clusters (SCC), Cluster Continuous Replication (CCR) or Standby Continuous Replication (SCR) for that matter. WHAT!? I hear some of you yell! Yes I am not kidding here. But to be more specific, only LCR and SCC have been removed from the Exchange Server product. CCR and SCR have been combined and have evolved into a more unified high availability framework in which the new Database Availability Group (DAG) act as the base component. This means that no matter if you are going to deploy a local or site-level highly available or disaster recoverable solution, you use a DAG. To make myself clear, with Exchange 2010, your one and only method to protect mailbox databases is by using DAG. recovery/uncovering-exchange-2010-database-availability-groups-dags-part1.html
