Your network contains two offices named Office1 and Office2. The offices are connected by
a WAN link. Each office is configured as an Active Directory site.
You have an Exchange Server 2010 organization. The organization contains four Mailbox
servers that are members of a database availability group (DAG). Two servers are located in
each site.
All Exchange and non-Exchange servers in Office1 become unavailable. Users in both
offices report that they cannot access their mailboxes.
You notice that all Mailbox database copies in Office2 have a Failed status. You need to
mount all Mailbox database copies in Office2.
What should you do first?

A.
Run Cluster.exe /ForceQuorum on the Mailbox server in Office2.

B.
Run the Set-DatabaseAvailabilityGroup cmdlet on the Mailbox server in Office2.

C.
Evict the Mailbox server from Office2 from the cluster.

D.
Configure an Alternate File Share Witness for the DAG.
