You have an Exchange Server 2013 organization that contains two servers. The servers are configured as
shown in the following table.
EX1 and EX2 are members of a database availability group (DAG) named DAG1. You have a database named
DB1 that replicates to EX1 and EX2.
EX1 fails.
You discover that DB1 does not mount on EX2.
You view the status of the mailbox databases as shown in the following table.
You need to ensure that the database attempts to mount on EX2 if EX1 fails.
What should you change?
A.
The AutoDatabaseMountDial setting to Lossless
B.
The AutoDatabaseMountDial setting to BestAvailabilty
C.
The activation preference of DB1\\EX2
D.
The activation preference of DB1\\EX1
Explanation:
* The MailboxServer.AutoDatabaseMountDial property gets or sets the automatic database mount behavior for
an Exchange server that is running the Mailbox server role in a continuous replication environment after a
database failover.
* The AutoDatabaseMountDial property specifies the automatic database mount behavior of a Mailbox server
after a failover. Each behavior is based on the copy queue length, or the number of logs that are recognized by
the passive copy that need to be replicated. If the copy queue length is greater than the value specified for the
behavior, the database does not automatically mount. If the copy queue length is less than or equal to the value
specified for the behavior, the Mailbox server tries to copy the remaining logs to the passive copy and mounts
the database.
* BestAvailabilityThe database automatically mounts immediately after a failover if the queue length is less than or equal to 12.
Incorrect:
Not A: Lossless
The database does not automatically mount until all logs generated on the active device are copied to the
passive device
