A corporate environment includes Exchange Server 2010 SP1. The Exchange Server environment
includes one Hub Transport server, one Client Access server, and one Mailbox server. You are
designing an infrastructure for a secondary datacenter that will provide site resiliency for the
primary datacenter that contains the existing Exchange Server environment. You have the following
requirements:
• Ensure that employees can access email if the primary datacenter fails.
• Ensure that each Mailbox database is active in only one datacenter at a time.
• Minimize the number of Exchange servers required.
You need to recommend a solution that meets the requirements. Which two actions should you
recommend? (Each correct answer presents part of the solution. Choose two.)
A.
In the secondary datacenter, deploy one server with the Hub Transport, Client Access, and
Mailbox roles. Create a database availability group (DAG) that spans both datacenters.
B.
In the secondary datacenter, deploy one server with the Hub Transport and Client Access roles,
and one server with the Mailbox role. Create a database availability group (DAG) that spans both
datacenters.
C.
Enable datacenter activation coordination (DAC) mode.
D.
Disable datacenter activation coordination (DAC) mode.
