HOTSPOT
Your network contains two Active Directory sites named Sitel and Site2. Both sites contain
an equal number of users. Each site contains two Exchange Server 2013 Mailbox servers.
You need to recommend a high-availability solution that meets the following requirements:
If a single Mailbox server fails, the active mailbox database copies on that server must fail
over to a Mailbox server in the same site.
If both Mailbox servers in the same site fail, the active mailbox databases copies must be
switched over to the other site manually.
If a WAN link fails, multiple copies of the same mailbox database must not be activated in
both sites simultaneously.
How should you configure the database availability groups (DAGs)? (To answer, configure
the appropriate options in the answer area.)
