The command executed (CREATE CONFIGURATION 'DGConfig' AS PRIMARY DATABASE IS 'PROD'

CONNECT IDENTIFIER IS PROD;) is used to create a Data Guard Broker configuration named

'DGConfig'. The successful execution of this command depends on several conditions:

A: The DG_BROKER_START parameter must be set to TRUE on the primary database to start the Data

Guard Broker processes. Without the broker processes running, the configuration cannot be created.

D: Oracle Net connectivity to the PROD database instance must be established on the primary host.

This is because the Data Guard Broker requires network accessibility to communicate with the

primary database and manage the configuration.

E: When the configuration is created, the Data Guard Broker configuration files are indeed

automatically created in the locations specified by the DG_BROKER_CONFIG_FILEn parameters on

the primary database.

It's important to note that the command will not automatically add the PRODSBY1 standby database

to the configuration (thus B and C are not correct), and there is no requirement for the standby

database to have Oracle Net connectivity defined on the primary host for the execution of this

command (making F incorrect as well).

Reference: This information can be validated in Oracle's Data Guard Broker documentation, which

outlines the requirements for setting up and managing a Data Guard configuration using the Data

Guard Broker.
