View the Exhibit and examine the output. Which two statements are true regarding the LISTENER2 listener? (Choose two.)
Correct Answer: B,D
Explanation/Reference: Explanation: Database Service Registration For a listener to forward client connections to an instance, the listener must know the name of the instance and where the instance's ORACLE_HOME is located. The listener can find this information in two ways: * Dynamic service registration: Oracle8i and later instances automatically register with the default listener on database startup. No additional listener configuration is required for the default listener. * Static service registration: Earlier releases of the Oracle database do not automatically register with the listener and, therefore, require that the listener configuration file contain a list of all database services that the listener will serve. You may still choose to use static service registration with newer releases if: - Your listener is not on the default port of 1521, and you do not want to configure your instance to register with a nondefault port - Your application requires static service registration
