To increase the availability of an Advanced Replication environment, you can add a new master to a replication group without quiescing the group. This is achived _________________.
Only when the new master site already has existing replication groups.
By issuing a single command to create , populate, and activate the new master.
When the master definition site is not the same for all of the master grouups.
Without impacting end users who are executing data manipulation language (DML) commands on the replicated tables.
