You edit the DGConnectIdentifier database property using the edit database set property DGMGRL command.
Which two are effects of this change?
A.
The fal_client database initialization parameter on all standby databases is updated with the new value.
B.
The service attribute of the log_archive_dest_n initialization parameter for any database referring to the
specified database is updated with the new value.
C.
The fal_client database initialization parameter for the specified database is updated with the new value.
D.
The broker configuration must be disabled and then enabled to use the new connection property.
E.
The service attribute of the log_archive_dest_n initialization parameter referring to all standby databases is
updated with the new value.
Explanation:
B: The DGConnectIdentifier configurable database property specifies the connection identifier the broker uses
when making connections to a database.
The value of this property is specified in the SERVICE attribute of the LOG_ARCHIVE_DEST_n parameter
when the broker configures redo transport services on the primary database.
A: The connect identifier for a database must allow all other databases in the configuration to reach it.

Apparently it should be FAL_SERVER not FAL_CLIENT; In that case Ans: A, B.
The DGConnectIdentifier property value is also used to set up the FAL_SERVER initialization parameter. If the DGConnectIdentifier property for any database is changed, the SERVICE attribute of the corresponding LOG_ARCHIVE_DEST_n initialization parameter will also be changed.
In addition, the FAL_SERVER initialization parameter will also be updated on every enabled standby database in the configuration.
