A person or program can have more than one session with an instance by logging in with the same user.

NO.45 You want to view the initialization parameter settings for only a specific PDB. Which of the following statements is true?

From the PDB, execute SELECT db_uniq_name, pdb_uid, name, value$ FROM pdb_spfile$;

From the CDB root, execute SELECT NAME, VALUE, ISPDB_MODIFIABLE FROM v$parameter;

From the CDB root, execute SELECT db_uniq_name, pdb_uid, name, value$ FROM pdb_spfiles;

From the PDB, execute SELECT NAME, VALUE, ISPDB_MODIFIABLE FROM v$parameter;

NO.46 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: LISTENER_1 = (ADDRESS = (PROTOCOL = TCP)(HOST = host1.abc.com)(PORT = 1521)). Which statement is true?

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

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

The LREG process registers services dynamically with the LISTENER_1 listener.

Dynamic service registration cannot be used for this database instance.

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

Dynamic service registration allows a database to automatically register its services with a listener without manual configuration in LISTENER.ORA. Let’s analyze each option:
A . The definition for LISTENER_1 requires a CONNECT_DATA section to enable dynamic service registration.
False. The CONNECT_DATA section is part of a client-side TNSNAMES.ORA entry for connecting to a service, not for listener registration. Dynamic registration is handled by the database’s LREG (Listener Registration) process, which uses the LOCAL_LISTENER parameter to locate the listener’s address (e.g., host1.abc.com:1521). No CONNECT_DATA is needed in the listener address definition itself. This option confuses client connection syntax with listener configuration.
Mechanics:The listener address in TNSNAMES.ORA (LISTENER_1) is sufficient for LREG to find and register with it, as long as the listener is running at that address.
B . LISTENER_1 must also be defined in the LISTENER.ORA file to enable dynamic service registration.
False. Dynamic registration doesn’t require the listener to be explicitly defined in LISTENER.ORA. The LOCAL_LISTENER parameter pointing to LISTENER_1 (resolved via TNSNAMES.ORA) tells LREG where to register services. If the listener is running on host1.abc.com:1521, LREG will find it without a LISTENER.ORA entry. However, LISTENER.ORA is needed tostartthe listener process, but that’s separate from dynamic registration.
Practical Note:If LISTENER.ORA isn’t configured, a default listener might run on port 1521, but the question implies LISTENER_1 is operational.
C . The LREG process registers services dynamically with the LISTENER_1 listener.
True. In Oracle 23ai, the LREG background process (replacing PMON’s registration role in earlier versions) dynamically registers database services with listeners specified by LOCAL_LISTENER. Here, LOCAL_LISTENER=LISTENER_1 resolves to host1.abc.com:1521 via TNSNAMES.ORA. LREG periodically sends service information (e.g., service names, instance details) to the listener, enabling clients to connect without static configuration.
Mechanics:LREG uses the TNS alias (LISTENER_1) to locate the listener’s IP and port, registers services like orcl or orclpdb, and updates the listener’s service table. This happens automatically every 60 seconds or on significant events (e.g., instance startup).
D . Dynamic service registration cannot be used for this database instance.
False. The setup (LOCAL_LISTENER set and a valid TNSNAMES.ORA entry) explicitly supports dynamic registration. No blockers (e.g., REGISTRATION_EXCLUDED_LISTENERS) are mentioned, so LREG can function normally.
E . There are two listeners named LISTENER and LISTENER_1 running simultaneously using port 1521 on the same host as the database in LISTENERS.
False. The question mentions only LISTENER_1 in the SPFILE and TNSNAMES.ORA. There’s no evidence of a second listener (LISTENER) or a LISTENERS configuration (possibly a typo). Two listeners can’t share the same port (1521) on the same host due to port conflicts unless explicitly configured with different IPs, which isn’t indicated here.

NO.47 You execute this command: CREATE SMALLFILE TABLESPACE sales DATAFILE ‘/u01/app/oracle/sales01.dbf’ SIZE 5G SEGMENT SPACE MANAGEMENT AUTO; Which two statements are true about the SALES tablespace?

Free space is managed using freelists.

It uses the database default block size.

It must be smaller than the smallest BIGFILE tablespace.

It is a locally managed tablespace.

Any data files added to the tablespace must have a size of 5 gigabytes.

NO.48 Which two statements are true about undo segments and the use of undo by transactions in an Oracle database instance?

Undo segments can be stored in the SYSTEM tablespace.

A single transaction may use multiple undo segments simultaneously.

Undo segments can be stored in the SYSAUX tablespace.

Undo segments can extend when a transaction fills the last extent of the undo segment.

Undo segments can wrap around to the first extent when a transaction fills the last extent of the undo segment.

NO.49 You want to apply the principle of Least Privilege in all your live databases. One of your requirements is to revoke unnecessary privileges from all users who have them using Privilege Analysis. Which three types of analyses can be done using the DBMS_PRIVILEGE_CAPTURE package?

Analysis of privileges that a user has on their own schema objects that they did not use.

Analysis of all privileges used by all users including administrative users in the database.

Analysis of all privileges used by all users but excluding administrative users in the database.

Analysis of privileges granted directly to a role that are then used by a user who has been granted that role.

Analysis of privileges granted indirectly to a role that are then used by a user who has beengranted that role.

Analysis of privileges that a user has on their own schema objects that they did use.

NO.50 Which two SQL Plan Management Advisor tasks are part of Automatic Maintenance Tasks?

The Automatic SQL Access Advisor task, which is used to manage an application SQL load.

The Automatic SQL Performance Analyzer task, which is used to provide details about impact of database changes to application SQL batch.

The Automatic Index Advisor task, which is used to create and maintain table indexes based on the DML load and operations.

The Automatic SQL Plan Management Evolve Advisor task, which evolves plans that have recently been added as the SQL plan baseline for statements.

The Automatic SQL Tuning Advisor tasks, which would examine the performance of high-load SQL statements and make recommendations for those statements.

NO.51 Which three statements are true about roles?

Roles must be password protected.

Roles may be granted to other roles.

The SET ROLE statement can enable one or more roles for a session.

Object privileges may not be granted to roles.

All roles granted to a user are set on default when the user logs in.

The SET ROLE statement can disable one or more roles for a session.

NO.52 Which three statements are true about the tools used to configure Oracle Net Services?

Oracle Net Manager can be used to centrally configure listeners on any database server target.

The Oracle Net Configuration Assistant is only used when running the Oracle installer.

Enterprise Manager Cloud Control can be used to centrally configure net service names for any database server target.

Enterprise Manager Cloud Control can be used to centrally configure listeners on any managed database server.

The lsnrctl utility requires a listener.ora file to exist before it is started.

Oracle Net Manager can be used to locally configure naming methods on a database server.

NO.53 Which of the following is true about the status of a PDB that has been unplugged from a CDB?

The STATUS column in CDB_PDBS of the unplugged PDB will be UNPLUGGED.

The STATUS column in CDB_PDBS of the unplugged PDB will be UNAVAILABLE.

The STATUS column in CDB_PDBS of the unplugged PDB will be REMOVED.

The STATUS column in CDB_PDBS of the unplugged PDB will be DISABLED.
