A corporate environment will include Exchange Server 2010 in two Active Directory Domain Services

Outlook Web App (OWA) connections. What should you recommend?

A.
Deploy one Client Access server array for each AD DS site.

B.
Deploy one Client Access server array.

C.
Configure a hardware load balancer for the Client Access servers.

D.
Configure Autodiscover in each AD DS site for a common internal URL.

Explanation:
In an organization that has multiple Active Directory sites and multiple Client Access in each site, you
can use Network Load Balancing (NLB) to load balance traffic proxies between the Client Access
servers in each site and for users directly accessing those servers. Just deploying a load balancer isn’t
enough ensure traffic is balanced effectively. You must also perform some additional configuration
of the InternalURL and ExterrnalURL properties. We recommend you include only Client Access
servers within the same Active Directory site in a load-balancing array. You can deploy NLB in an
Internet-facing Active Directory site and in a non-Internet-facing Active Directory site.
