Which are two ways for a database service to be recognized by a listener in Oracle Database 12c? (Choose two.)

In Oracle 12c and later, the LREG (Listener Registration) background process is specifically tasked with dynamically registering information about database services and their dispatchers with the listener.

The SMON (System Monitor) process manages instance recovery and temporary segments, but it is not involved in registering database services with the listener.

Static registration in the listener.ora file uses the SERVICE_NAME or SID_NAME parameters, not the GLOBAL_DBNAME parameter, for service recognition.

While PMON previously handled listener registration, in Oracle 12c and later, the LREG process has taken over the responsibility for dynamic service registration with the listener.

Static registration involves manually configuring service information within the listener.ora file, typically using the SERVICE_NAME parameter in the SID_LIST section, which allows the listener to recognize services that may not dynamically register.
