Correct Answer: ABE
Explanation/Reference:
A: Oracle Enterprise Manager Cloud Control (Cloud Control) works with the Oracle Data Guard monitor to automate and simplify the management of an Oracle Data Guard configuration.
With Cloud Control, the complex operations of creating and managing standby databases are simplified through Oracle Data Guard management pages and wizards, including:
* A switchover operation that helps you switch roles between the primary database and a standby database.
B (not D): The Oracle Data Guard monitor process (DMON) is an Oracle background process that runs on every database instance that is managed by the broker.
E: The broker’s DMON process persistently maintains information about all members of the broker configuration in a binary configuration file.
