You have an Exchange Server 2010 organization. The network contains an Exchange Server 2010
Mailbox server named Server1. All mailboxes are stored on Server1. You perform a Typical
installation of Exchange Server 2010 on a new server named Server2. You plan to implement
redundancy for mailbox access. You need to recommend a solution that ensures that client
computers can reconnect to their mailbox within five minutes if Server1 fails. What should you
recommend?
A.
Configure cluster continuous replication (CCR).
Implement a file share witness.
B.
Configure a Network Load Balancing cluster that includes Server1 and Server2.
Implement Active Directory-integrated DNS zones.
C.
Configure a database availability group (DAG) that includes Server1 and Server2.
Set the time to live (TTL) for the DNS record.
D.
Configure a database availability group (DAG) that includes Server1 and Server2.
Use the same certificate for both servers.
