15.An architect is designing storage for a new vSphere environment to meet the following requirements:
-Asynchronous replication is required between two sites.
-The impact on the storage layer should not impact the performance of the compute layer.
-Each application tier will require different replication attributes.
-Virtual machine live migration across compute and storage must be supported
-Virtual machine aware back up will be leveraged
-Operational management overhead should be minimized
-Operational automation should be supported
-Which storage design recommendations would meet the requirements?

A、　 Two new Fibre Channel storage arrays will be deployed, one at either site.Each application tier will be initially provisioned a new LUN.Data replication will be offloaded to the new arrays.

B、　 Two new vSphere clusters enabled with vSAN will be deployed, one at either site.vSAN will be used to provide policy-based management for each application tier.vSphere Replication will be used to replicate the virtual machine data in an asynchronous configuration.

C、　 Two new ISCSI storage arrays will be deployed, one at either site.Each application tier will be initially provisioned a new LUN.Data replication will be offloaded to the new arrays.

D、　 Two new storage arrays will be deployed, one at either site. vSphere Volumes (vVOLs) will be used to provide policy-based management for each application tier.Data replication will be offloaded to the new arrays.
