The image below depicts a high-level diagram of configuration auditing within WebLogic Server. When Administrators make configuration changes to the WebLogic Server domain, those changes are sent to the audit provider for logging. 

What task must be performed in order to make configuration audit messages in the log meaningful to an observer? 

Answer options:

A. Define unique users for all administrators.
B. Configure a persistent store for log messages.
C. Configure the CONFIG severity level.
D. Define the audit message listener for audit messages.

D

You can configure the Administration Server to emit a log message when a user changes the configuration or invokes management operations on any resource within a domain. For example, if a user disables SSL on a Managed Server in a domain, the Administration Server emits a log message. These messages provide an audit trail of changes within a domain`s configuration. You can then create and use a JMX listener and filter that respond to configuration auditing messages. Reference: https://docs.oracle.com/cd/E13222_01/wls/docs81/jmx/notifications.html
