You have an Active Directory forest that contains one site. You plan to deploy an Exchange
organization. All servers in the organization will have Exchange Server 2010 Service Pack 1 (SP1)
installed. The relevant Mailbox servers are configured as shown in the following table.

Each Mailbox server will host 2,000 mailboxes. Corporate policy states that the servers must have a
maximum write latency of 100 ms and an average write latency of 10 ms. The hardware vendor for
the planned deployment provides test hardware. You need to recommend a solution to ensure that
the planned deployment meets the requirements of the corporate policy. Which of the following
solutions is the best recommendation? (More than one answer choice may achieve the goal. Select
the BEST answer.)

A.
Identify the workload at which the hardware can deliver acceptable latency by using the Jetstress
tool.

B.
Gather a baseline of the disk I/O usage by using the Windows Performance Monitor.

C.
Calculate the number of IOPS required for the planned deployment by using the Exchange 2010
Mailbox Server Role Requirements Calculator.

D.
Test the performance of the hardware under a simulated user workload by using the Loadgen
tool.
