NEW QUESTION # 24
Your database instance is started with an SPFILE. A PFILE is also available. You execute this command: ALTER SYSTEM SET DB_CACHE_SIZE=100K; Where does the value change?

• A. In the SPFILE and PFILE
• B. In the SPFILE and memory
• C. In the SPFILE, PFILE, and memory
• D. Only in the SPFILE
• E. Only in memory

Answer: B

Explanation:
B .True. Without SCOPE, ALTER SYSTEM defaults to BOTH (memory and SPFILE); PFILE isn't updated unless manually recreated.

NEW QUESTION # 25
Which two statements are true about Fine-Grained Auditing (FGA)?

• A. FGA policies by default can be created by a schema owner on an object in their schema.
• B. FGA policies can be created by a user having granted the CREATE_FGA_POLICY role.

• D. FGA policies can only be created by a user with SYSDBA privilege.
• E. FGA policies can be created by a user having EXECUTE privilege on the DBMS_FGA package.

Answer: C,E

Explanation:
A .False. Schema owners need EXECUTE on DBMS_FGA.
B .False. Not limited to SYSDBA.
C .True. AUDIT_ADMIN includes FGA creation rights.
D .False. No such role exists.
E .True. DBMS_FGA.ADD_POLICY requires this privilege.

NEW QUESTION # 26
Which two statements describe why Database Auditing is a security requirement?

• A. To protect against data corruption.
• B. To monitor suspicious activity.
• C. To alert DBAs about system issues.
• D. To monitor proper usage of the system and data by privileged users.
• E. To protect against data theft by a non-authorized user.

Answer: B,D

Explanation:
A .True. Auditing tracks suspicious actions.
B .False. That's monitoring, not auditing.
C .False. Auditing detects, doesn't prevent.
D .False. Corruption is a reliability issue.
E .True. Ensures privileged user compliance.

NEW QUESTION # 27
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 setting the TIMED_STATISTICS_LEVEL system parameter to FALSE.
• B. By setting the STATISTICS_LEVEL parameter to BASIC.
• C. By executing the PL/SQL procedure DBMS_TIME_STATISTIC.LEVEL(BASIC).
• D. By setting the TIMED_STATISTICS system parameter to FALSE.
• E. By executing the PL/SQL procedure DBMS_TIME_STATISTIC.DISABLE(TRUE).

Answer: B,D

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 # 28
As the DBA, you execute this command: GRANT CREATE VIEW TO usr1 WITH ADMIN OPTION; USR1 then executes: GRANT CREATE VIEW TO usr2 WITH ADMIN OPTION; USR2 then executes: GRANT CREATE VIEW TO usr3; Which statement is true?

• A. USR1 can revoke the CREATE VIEW privilege from USR3.
• B. The DBA can revoke only ADMIN OPTION from USR1.
• C. When the DBA revokes the CREATE VIEW privilege from USR1, it is neither revoked from USR2 nor USR3.
• D. When the DBA revokes the CREATE VIEW privilege from USR2, it is revoked from USR3.
• E. When the DBA revokes the CREATE VIEW privilege from USR1, it is revoked from USR2 but not USR3.

Answer: C,D

Explanation:
A .False. Revoking from USR1 doesn't cascade due to WITH ADMIN OPTION.
B .True. Revoking from USR2 cascades to USR3 because USR2 granted it.
C .False. DBA can revoke the full privilege, not just ADMIN OPTION.
D .False. USR1 can't revoke from USR3 directly; only the grantor (USR2) can.
E .True. WITH ADMIN OPTION breaks the revoke chain from USR1 onward.

NEW QUESTION # 29
Which three statements are true about UNDO and REDO?

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

Answer: D,E,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.

NEW QUESTION # 30
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. Dynamic service registration cannot be used for this database instance.
• B. The LREG process registers services dynamically with the LISTENER_1 listener.
• C. The definition for LISTENER_1 requires a CONNECT_DATA section to enable dynamic service registration.
• D. There are two listeners named LISTENER and LISTENER_1 running simultaneously using port 1521 on the same host as the database in LISTENERS.
• E. LISTENER_1 must also be defined in the LISTENER.ORA file to enable dynamic service registration.

Answer: B

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 # 31
Which data dictionary view describes the data sources of external tables?

• A. DBA_ALL_USER_EXTERNAL_TABLES
• B. DBA_ALL_USER_TABLES
• C. DBA_ALL_USER_TAB_COLUMNS
• D. DBA_ALL_USER_EXTERNAL_LOCATIONS

Answer: D

Explanation:
A .True. DBA_EXTERNAL_LOCATIONS (or prefixed variants) shows external table data sources (e.g., file paths).
B-D .False. These views cover columns or tables but not external sources specifically.

NEW QUESTION # 32
What are Optimizer Statistics?

• A. Optimizer Statistics are part of system performance statistics stored in AWR required for calculating SQL execution plans.
• B. Optimizer Statistics are table, column, index, and system statistics used for generating efficient SQL execution plans.
• C. Optimizer Statistics are statistics about data distribution within Oracle Datafiles.
• D. Optimizer Statistics are a set of data distribution statistics collected in real time as data is inserted, deleted, or updated, which are stored in AWR and used for generating SQL execution plans.

Answer: B

Explanation:
A .False. Not real-time; collected periodically.
B .False. Not about datafile distribution.
C .True. Includes table, column, index stats for plan generation.
D .False. Stored in data dictionary, not AWR.

NEW QUESTION # 33
What is the result of the following command? ALTER PLUGGABLE DATABASE PDB1 DISCARD STATE;

• A. It should be used whenever PDB1 open mode needs to be changed.
• B. It is unnecessary if the PDB is in the process of being upgraded.
• C. PDB1 is reverted to its default properties, which includes not to automatically open after a CDB restart.
• D. PDB1 is reverted to its default properties, which includes automatic opening after a CDB restart.

Answer: C

Explanation:
A .False. DISCARD STATE isn't tied to upgrades; it resets PDB startup behavior.
B .True. Discards saved state, reverting PDB1 to manual open mode (not auto-open) after CDB restart.
C .False. Default is not auto-open; it's manual unless explicitly saved as OPEN.
D .False. Used for state management, not general mode changes (e.g., OPEN READ WRITE).

NEW QUESTION # 34
Which three statements are true about dynamic performance views?

• A. They can be queried only when the database is open.
• B. They are owned by the SYSTEM user.

• D. Data displayed by querying dynamic performance views is derived from metadata in the data dictionary.
• E. V$FIXED_TABLE can be queried to display the names of all dynamic performance views.

Answer: C,D,E

Explanation:
A .True. V$ views reflect real-time memory data, not consistent snapshots.
B .True. V$FIXED_TABLE lists all V$ views.
C .True. Data comes from memory structures and data dictionary metadata.
D .False. Owned by SYS, not SYSTEM.
E .False. Some V$ views are accessible in MOUNT state.
