Explanation:
BE: The broker simplifies switchovers and failovers by allowing you to invoke them using a single key click in
Oracle Enterprise Manager or a single command at the DGMGRL command-line interface (referred to in this
documentation as manual failover).
C: The broker coordinates database state transitions and update database properties dynamically with the
broker recording the changes in a broker configuration file that includes profiles of all the databases in the
configuration. The broker propagates the changes to all databases in the configuration and their server
parameter files.
