Oracle Database 23ai Administration Associate Sample Questions (Q64-Q69):

NEW QUESTION # 64
Which three statements are true about an SPFILE?

A. It can be created by SYS from an idle instance.
B. It contains only static initialization parameters.
C. It contains initialization parameters whose values can be changed using the ALTER SYSTEM statement.
D. It must exist for a database instance to start.
E. It can be used to create a PFILE.

Answer: A,C,E

Explanation:
A .True. CREATE SPFILE FROM PFILE works when idle.
B .False. Includes dynamic parameters too.
C .True. CREATE PFILE FROM SPFILE generates a PFILE.
D .False. A PFILE can start the instance if no SPFILE exists.
E .True. Dynamic parameters (e.g., DB_CACHE_SIZE) are modifiable.

NEW QUESTION # 65
In which two ways would you disable timing information collected for wait events and much of the performance monitoring capability of the database?

A. By executing the PL/SQL procedure DBMS_TIME_STATISTIC.DISABLE(TRUE).
B. By setting the TIMED_STATISTICS_LEVEL system parameter to FALSE.
C. By executing the PL/SQL procedure DBMS_TIME_STATISTIC.LEVEL(BASIC).
D. By setting the TIMED_STATISTICS system parameter to FALSE.
E. By setting the STATISTICS_LEVEL parameter to BASIC.

Answer: D,E

Explanation:
A .True. TIMED_STATISTICS = FALSE disables timing data collection.
B .False. No such procedure exists.
C .False. No TIMED_STATISTICS_LEVEL parameter exists.
D .True. STATISTICS_LEVEL = BASIC disables most performance monitoring.
E .False. No such procedure exists.

NEW QUESTION # 66
Which resource plan is used to manage the resources for the predefined maintenance window?

A. The predefined maintenance window starts automatically with 20% of the system resources ...
B. By default, all predefined maintenance windows use the DEFAULT_MAINTENANCE_PLANresource plan, and automated maintenance tasks run under subplan called ORA$AUTOTASK.
C. The resources used by the predefined maintenance window can only be adjusted if you create a new resource plan in Resource Manager ...
D. The SYS_GROUP consumer resource group policies define the resources assigned ...

Answer: B

Explanation:
A .True. Oracle 23ai uses DEFAULT_MAINTENANCE_PLAN with ORA$AUTOTASK subplan for maintenance tasks (e.g., stats gathering). Others are incorrect or speculative.

NEW QUESTION # 67
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?

A. The definition for LISTENER_1 requires a CONNECT_DATA section to enable dynamic service registration.
B. LISTENER_1 must also be defined in the LISTENER.ORA file to enable dynamic service registration.
C. The LREG process registers services dynamically with the LISTENER_1 listener.
D. Dynamic service registration cannot be used for this database instance.
E. There are two listeners named LISTENER and LISTENER_1 running simultaneously using port 1521 on the same host as the database in LISTENERS.

Answer: C

Explanation:
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.

NEW QUESTION # 68
Which three statements are true about UNDO and REDO?

A. REDO is used for read consistency.
B. UNDO is used for some flashback operations.
C. REDO is used for instance recovery.
D. Both REDO and UNDO can be multiplexed.
E. REDO is used for ROLLBACK.
F. UNDO is used for read consistency.

Answer: B,C,F

Explanation:
A . REDO is used for read consistency.False. Read consistency is achieved using UNDO, which provides a consistent view of data as of a specific point in time. REDO logs changes for recovery, not consistency.
B . UNDO is used for some flashback operations.True. Flashback features like Flashback Query and Flashback Table rely on UNDO to reconstruct past states of data.
C . UNDO is used for read consistency.True. UNDO stores pre-change data, enabling multi-version read consistency for queries.
D . Both REDO and UNDO can be multiplexed.False. REDO logs can be multiplexed (mirrored across multiple destinations), but UNDO is managed within a single UNDO tablespace per instance (though it can have multiple data files).
E . REDO is used for ROLLBACK.False. ROLLBACK uses UNDO to revert changes; REDO logs the changes but isn't used to undo them.
F . REDO is used for instance recovery.True. REDO logs are replayed during instance recovery to reapply committed changes after a crash.
