Which command should you run?

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

You need to ensure that if the active copy of NYDB01 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.
