Which TWO statements are true regarding Data Guard Broker?

The Data Guard Broker is a framework that automates and centralizes the management and monitoring of a Data Guard configuration. Two of its primary functions are simplifying role transitions and providing comprehensive monitoring. It allows administrators to perform complex switchover and failover operations with a single command. It also provides a consolidated view of the entire configuration's health, including the status of redo transport and log apply services, apply lag, and transport lag, making it easy to monitor the environment.

A. The Broker manages an existing Data Guard configuration; it does not create the standby database itself. Standby creation is done with tools like RMAN or Enterprise Manager.
C. The DMON process is started by the database instance when the DGBROKERSTART parameter is set to TRUE, not directly by the Broker.
E. When creating a configuration, you add the primary first. You cannot add a primary to an existing configuration, as it can only have one primary.
