Oracle Database 23ai Administration Associate Sample Questions (Q16-Q21):

NEW QUESTION # 16
Your data center uses Oracle Managed Files (OMF) for all databases. All tablespaces are smallfile tablespaces. SALES_Q1 is a permanent user-defined tablespace in the SALES database. The following command is about to be issued by a DBA logged in to the SALES database: ALTER TABLESPACE sales_q1 ADD DATAFILE; Which two actions independently ensure that the command executes successfully?

A. Ensure that DB_RECOVERY_FILE_DEST and DB_CREATE_FILE_DEST each specify locations with at least 50 MB of available space.
B. Add the AUTOEXTEND ON clause with NEXT set to 100M.
C. Specify a path in the DATAFILE clause of the command specifying a location with at least 100 MB of available space.
D. Ensure that DB_CREATE_FILE_DEST specifies a location with at least 100 MB of available space.
E. Ensure that DB_RECOVERY_FILE_DEST and DB_CREATE_FILE_DEST each specify locations with at least 50 MB of available space.

Answer: D,E

Explanation:
With OMF enabled, Oracle automatically manages file creation. The command ALTER TABLESPACE sales_q1 ADD DATAFILE without a file specification relies on initialization parameters:
A . Specify a path in the DATAFILE clause ... with at least 100 MB of available space.False. With OMF, explicitly specifying a path overrides OMF behavior, but it's not required for success if OMF parameters are set correctly.
B . Add the AUTOEXTEND ON clause with NEXT set to 100M.False. AUTOEXTEND is optional and affects file growth, not the initial creation success, which depends on available space in the OMF location.
C . Ensure that DB_RECOVERY_FILE_DEST and DB_CREATE_FILE_DEST each specify locations with at least 50 MB of available space.True. If both parameters are set,Oracle may use either for data files (depending on context), and sufficient space (e.g., 50 MB minimum for a smallfile) ensures success.
D . Ensure that DB_CREATE_FILE_DEST specifies a location with at least 100 MB of available space.True. This is the primary OMF parameter for data files; sufficient space (typically 100 MB minimum for a new file) guarantees the command succeeds.
E . Ensure that DB_RECOVERY_FILE_DEST and DB_CREATE_FILE_DEST each specify locations with at least 50 MB of available space.False. This is redundant with C; only one needs sufficient space, though C's phrasing makes it a valid independent action.

NEW QUESTION # 17
What are the three components of Oracle Database Automatic Maintenance Tasks?

A. A set of tasks that are started automatically at regular intervals to perform maintenance operations on the database.
B. Oracle Database Resource Manager, which enables you to manage and configure system resources used by the Automatic Maintenance Tasks.
C. A database alert log that stores details about major database operations and errors, which is used to manage cluster performance.
D. A diagnostic system that collects database error logs and details about database failures that can be found to diagnose complete file.
E. A packaging system that allows you to combine all error and failure logs to share with Oracle Support.
F. The maintenance windows managed by Oracle Database Scheduler, which are predefined time intervals permitting scheduled tasks.

Answer: A,B,F

Explanation:
A .False. Diagnostic collection is ADR, not AMT.
B .True. Resource Manager allocates resources to AMTs.
C .True. Scheduler defines maintenance windows.
D .False. Packaging is IPS/ADR, not AMT.
E .False. Alert log is separate from AMTs.
F .True. Tasks like stats collection are AMTs.

NEW QUESTION # 18
Which two statements are true about the Automatic Diagnostic Repository (ADR)?

A. The ADR base defaults to $ORACLE_HOME/dbs if the DIAGNOSTIC_DEST parameter and the ORACLE_BASE environment variable are not set.
B. It is held inside an Oracle database schema.
C. It supports diagnostics for Automatic Storage Management (ASM).
D. It supports diagnostics for Oracle Clusterware.
E. The ADR base defaults to $ORACLE_HOME/rdbms/admin if neither DIAGNOSTIC_DEST nor ORACLE_BASE is set.

Answer: C,D

Explanation:
A .False. ADR is file-based, not in a schema.
B .False. No such default exists.
C .True. ADR logs ASM diagnostics.
D .True. Supports Clusterware diagnostics.
E .False. Defaults to $ORACLE_BASE or /u01/app/oracle if unset.

NEW QUESTION # 19
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. LISTENER_1 must also be defined in the LISTENER.ORA file to enable dynamic service registration.
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. The LREG process registers services dynamically with the LISTENER_1 listener.

Answer: E

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 # 20
Which two statements are true about views used for viewing tablespace and datafile information?

A. Tablespace free space can be viewed in V$TABLESPACE.
B. V$TABLESPACE displays information that is contained in the control file about tablespaces.
C. Tablespace free space can be viewed in DBA_TABLESPACES.
D. V$TABLESPACE displays information about tablespaces contained in the data dictionary.
E. A datafile can be renamed when the database is in MOUNT state and the new file name is displayed when querying DBA_DATA_FILES after the database is opened.

Answer: B,E

Explanation:
A .False. V$TABLESPACE doesn't show free space directly.
B .False. It's from the control file, not the data dictionary.
C .True. Renaming in MOUNT state updates DBA_DATA_FILES post-open.
D .False. DBA_TABLESPACES shows attributes, not free space directly (use DBA_FREE_SPACE).
E .True. V$TABLESPACE reflects control file data.
