You have an Exchange organization. All servers in the organization have Exchange Server
2010 Service Pack 1 (SP1) installed. The organization contains a database availability group
(DAG) named DAG1. DAG1 contains three Mailbox servers including a server named
Server1. Server1 fails. You restore Server1. You need to ensure that Server1 can replicate
mailbox databases from DAG1. What should you do first?
A.
Modify the GUID for Server1.
B.
Remove the object for Server1 from DAG1.
C.
Remove the default mailbox database from Server1.
D.
Disable log truncation for the mailbox databases in DAG1.
Explanation:
Remove-DatabaseAvailabilityGroupServer -Identity DAG1 -MailboxServer MBX1 –
ConfigurationOnly
High level steps to recover Server1:
1) Remove the failed server’s configuration from the DAG by using the RemoveDatabaseAvailabilityGroupServer cmdlet. Because the DAG member being removed was
offline and could not be brought online, you must add the ConfigurationOnly parameter to
the above command.
2) Reset the server’s computer account in Active Directory.
3) Open a Command Prompt window. Using the original Setup media, run the following
command: Setup /m:RecoverServer
4) When the Setup recovery process is complete, add the recovered server to the DAG by
using the Add-DatabaseAvailabilityGroupServer cmdlet.
5) After the server has been added back to the DAG, you can reconfigure mailbox database
copies by using the Add-MailboxDatabaseCopy cmdlet.http://technet.microsoft.com/en-us/library/dd638206.aspx
