QUESTION 12
In the spfile of a single instance database, LOCAL_LISTENER is set to LISTENER_1.
The TNSNAMES.ORA file in $ORACLE_HOME/network/admin in the database home contains:

Which statement is true?

Dynamic service registration cannot be used for this database instance

The LREG process registers services dynamically with the LISTENER_1 listener

LISTENER_1 must also be defined in the LISTENER.ORA file to enable dynamic service registration

There are two listeners named LISTENER and LISTENER_1 running simultaneously using port 1521 on the same host as the database instances

The definition for LISTENER_1 requires a CONNECT_DATA section to enable dynamic service registration

The listener forwards client requests to supported services. These services are dynamically registered with the listener. This dynamic registration feature is called service registration. The registration is performed by the Listener Registration (LREG) process. Dynamic service registration does not require any manual configuration in the listener.ora file.

A TRUNCATE command issued in a session causes all rows in a GLOBAL TEMPORARY TABLE for the issuing session to be deleted.

GLOBAL TEMPORARY TABLE rows inserted by a session are available to any other session whose user has been granted select on the table.

QUESTION 18
Which two statements are true about trace files produced by the Oracle Database server? (Choose two.)

They can be written by server processes

Trace files are written to the Fast Recovery Area (FRA)

Trace file names are based on the database name concatenated with a sequential number

Reference:
https://docs.oracle.com/html/E25494_01/monitoring001.htm
Each server and background process can write to an associated trace file. When an internal error is detected by a process, it dumps information about the error to its trace file. Some of the information written to a trace file is intended for the database administrator, and other information is for Oracle Support Services. Trace file information is also used to tune applications and instances.
