Your company has five main offices. Each office contains a data center.
You plan to deploy an Active Directory forest and an Exchange Server 2013 organization. Each office will be configured as a separate Active Directory site. User mailboxes will be hosted in each site.
You need to recommend an Exchange Server 2013 deployment strategy that meets the following requirements:
Provides redundancy for all mailbox databases
Creates a temporary copy of outbound email messages
Minimizes the number of servers deployed to the network
Provides redundancy for client access by using Network Load Balancing (NLB) What should you recommend?
A. In each site, deploy one server that has both the Mailbox server role and the Client Access server role installed and another server that has the Client Access server role installed.
B. In each site, deploy one server that has the Mailbox server role installed and two servers that have the Client Access server role installed.
C. In each site, deploy one server that has both the Mailbox server role and the Client Access server role installed.
