You have an Exchange Server 2010 organization. You plan to deploy a database availability group
(DAG). You need to recommend disk configurations for the servers in the organization. The solution
must minimize costs. What should you recommend?
A.
7200 RPM SATA hard disks in a Direct Attach Storage (DAS)
B.
7200 RPM SATA hard disks in a Network Attached Storage (NAS)
C.
15000 RPM SAS hard disks in a Network Attached Storage (NAS)
D.
15000 RPM SAS hard disks in a Fiber Channel (FC) Storage Area Network (SAN)
Explanation:
DAG has been designed to run well on low cost hard drive storage. Generally, there are no special
storage requirements that are specific to DAGs or mailbox database copies. DAGs don’t require or
use cluster managed shared storage.
