8. Which are two ways for a database service to be recognized by a listener in Oracle Database 12c?
A) Static registration in the listener.ora file using the service_name parameter
B) Dynamic Registration by the smon process
C) Static registration in the listener.ora file using the global_dbname parameter
D) Dynamic Registration by the pmon process
E) Dynamic Registration by the lreg process
Answer：AE
(解析：如果是静态注册的监听，使用 service_name 设置值为 cuug.oracle.com，但是在启动实例时发现 service name 不是cuug.oracle.com，而是实例名，说明它没有被承认(recognized);而用 global_dbname 设置的值就能够被承认。动态注册的只有用 lreg 进程才可以。来自3组：1015267481)
