You have an Exchange Server 2013 organization that contains the servers configured as shown in the
following table.
All mailbox servers are members of a database availability group (DAG) named DAG1. DAG1 has
Datacenter Activation Coordination (DAC) mode enabled. The data center in Dallas experiences a
power failure, causing quorum to be lost.
You need to mount the databases in the data center in Houston.

Stop-DatabaseAvailabilityGroup -Identity DAG1 -MailboxServer EX1 -ConfigurationOnly.
B.
Restore-DatabaseAvailabilityGroup -Identity DAG1 -ActiveDirectorySite Exchange-Site –
AlternateWitnessServer -AlternateWitnessDirectory D:\DAG1

D.

Must be A as there is only 1 AD site (this rules C out)
