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.
