You have two Exchange Server 2010 Service Pack 1 (SP1) servers named Server1 and
Server2. Both servers have the Client Access, Hub Transport, and Mailbox server roles
installed. The servers are members of a database availability group (DAG).
You need to ensure that all Microsoft Outlook users automatically connect to an available
Client Access server if a single server or service fails.
What should you do?

A.
from DNS manager, create two new records for the Client Access servers.

B.
from Failover Cluster Manager, create a new service named Client Access Server and
assign a new IP address.

C.
Install the Network Load Balancing feature on each server and assign a second IP
address to each network adapter.

D.
Deploy a hardware load balancer. Create a DNS record for the virtual IP address and
configure a Client Access server array.
