You have an Exchange Server 2013 organization that contains one office in Los Angeles and one
office in New York.
All servers have the Mailbox server role and the Client Access server role installed and are members
of a data availability group (DAG) named DAG1. The servers and databases are shown in the exhibit.
(Click the Exhibit button.)
You need to ensure that if the active copy of LADB01 fails, a server in the same site will attempt to
activate a copy of the database before a server in another site does. The solution must not influence
the activation of other database copies.
Which command should you run?
A.
Set-databaseavailabilitygroupserver -identity dagl-alternatewitnessserverfs2
B.
Set-mailboxserver-identity ex6 autodatabasemountdial bestavailability
C.
Suspend-mailboxdatabasecopy-identity ladb01\ex6 -activationonly
D.
Set-mailboxdatabasecopy -identity ladb01\ex2-activationpreference l
Explanation:
Use the Set-MailboxDatabaseCopy cmdlet to configure the properties of a database copy. With this
cmdlet, you can configure the replay lag time, truncation lag time, and activation preference value
for a mailbox database copy.
/ activationpreference The ActivationPreference parameter value is used as part of Active Manager’s
best copy
selection process and to redistribute active mailbox databases throughout the database availability
group (DAG) when using the RedistributeActiveDatabases.ps1 script. The value for the
ActivationPreference parameter is a number equal to or greater than 1, where 1 is at the top of the
preference order. The position number can’t be larger than the number of database copies of the
mailbox database.
Incorrect: Not C: Use the Suspend-MailboxDatabaseCopy cmdlet to block replication and replay
activities (log copying and replay) or activation for a database configured with two or more database
copies.
/ Identity The Identity parameter specifies the name of the database copy being suspended.
/ ActivationOnly The ActivationOnly switch specifies whether to suspend only activation for the
mailbox database copy.
Not really liking this question.
I’m guessing what they are saying is for this labdb01, you should do something like this:
Set-mailboxdatabasecopy -identity ladb01\ex2-activationpreference l
Set-mailboxdatabasecopy -identity ladb01\ex1-activationpreference 2
Set-mailboxdatabasecopy -identity ladb01\ex3-activationpreference 3
Alternatively you could run this Suspend-mailboxdatabasecopy-identity ladb01\ex* -activationonly against all 3 of the servers on the other site and you’d have to manually intervene in order to activate the DB at the other site.
Still I don’t like the question’s answers since they aren’t really a complete solution
This should probably ask what you should run first rather than what should you run.
Why not C, when database copy is suspended in the server ex6 obviously the quourum allways will be higher at site 1.
C. Suspend-mailboxdatabasecopy-identity ladb01\ex6 -activationonly
