NEW QUESTION # 60
Which three are benefits of using temp UNDO when performing DML on global temporary tables?
- A. It reduces I/Os to the SYSTEM tablespace.
- B. It permits DML on global temporary tables even if the database is opened read-only.
- C. It reduces the amount of redo generated.
- D. It reduces I/Os to the SYSAUX tablespace.
- E. It reduces the amount of UNDO stored in the UNDO tablespace.
Answer: A,C,E
Explanation:
Temp UNDO, introduced in Oracle 12c and refined in 23ai, stores undo for global temporary tables (GTTs) in temporary tablespaces:
A . It permits DML on GTTs even if the database is opened read-only.False. In read-only mode, DML on GTTs is allowed regardless of temp UNDO, as GTT data is session-private, but temp UNDO doesn't specifically enable this.
B . It reduces the amount of UNDO stored in the UNDO tablespace.True. Temp UNDO stores undo in the temporary tablespace, reducing usage of the permanent UNDO tablespace.
C . It reduces I/Os to the SYSTEM tablespace.True. By avoiding permanent undo, it reduces metadata updates in the SYSTEM tablespace related to undo management.
D . It reduces the amount of redo generated.True. Temp UNDO changes are not redo-logged to the same extent as permanent undo, minimizing redo generation.
E . It reduces I/Os to the SYSAUX tablespace.False. SYSAUX is unrelated to undo management; temp UNDO affects temporary and SYSTEM tablespaces.
NEW QUESTION # 61
What are the three components of Oracle Database Automatic Maintenance Tasks?
- A. A packaging system that allows you to combine all error and failure logs to share with Oracle Support.
- B. The maintenance windows managed by Oracle Database Scheduler, which are predefined time intervals permitting scheduled tasks.
- C. A database alert log that stores details about major database operations and errors, which is used to manage cluster performance.
- D. Oracle Database Resource Manager, which enables you to manage and configure system resources used by the Automatic Maintenance Tasks.
- E. A diagnostic system that collects database error logs and details about database failures that can be found to diagnose complete file.
- F. A set of tasks that are started automatically at regular intervals to perform maintenance operations on the database.
Answer: B,D,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 # 62
Which three statements are true about Oracle Managed Files (OMF)?
- A. If DB_RECOVERY_FILE_DEST is specified, at least two different locations must be specified for DB_CREATE_ONLINE_LOG_DEST_n.
- B. If DB_CREATE_ONLINE_LOG_DEST_1 is specified but DB_CREATE_FILE_DEST is not, new data files and temp files are stored in DB_CREATE_ONLINE_LOG_DEST_1 by default.
- C. If DB_RECOVERY_FILE_DEST is specified but DB_CREATE_ONLINE_LOG_DEST_n is not, the redo logs and control files are placed in DB_RECOVERY_FILE_DEST by default.
- D. If only DB_CREATE_FILE_DEST is specified, only data files and temp files are Oracle managed.
- E. If DB_CREATE_FILE_DEST is specified but DB_CREATE_ONLINE_LOG_DEST_n is not, new redo logs and control files are stored in DB_CREATE_FILE_DEST by default.
- F. If only DB_CREATE_ONLINE_LOG_DEST_1 is specified, only redo logs and control files are Oracle Managed.
Answer: B,C,E
Explanation:
A .True. Without DB_CREATE_ONLINE_LOG_DEST_n, redo logs and control files default to DB_RECOVERY_FILE_DEST.
B .False. If only DB_CREATE_FILE_DEST is set, redo logs and control files also use it unless overridden.
C .True. DB_CREATE_ONLINE_LOG_DEST_1 becomes the default for data files and temp files if DB_CREATE_FILE_DEST is unset.
D .True. DB_CREATE_FILE_DEST serves as the default for all file types if no log-specific parameter is set.
E .False. Data files and temp files would also use DB_CREATE_ONLINE_LOG_DEST_1 if no other parameter is specified.
F .False. No such requirement exists; DB_RECOVERY_FILE_DEST operates independently.
NEW QUESTION # 63
One of your database instances was shut down normally and then started in NOMOUNT state. You then executed this command: ALTER DATABASE MOUNT; Which two of these actions are performed?
- A. Online data files are opened.
- B. Online redo logs are opened.
- C. Oracle shared memory structures are allocated.
- D. The alert log has instance startup details written to it.
- E. Control files are read.
- F. The initialization parameter file is read.
Answer: D,E
Explanation:
A .False. Data files open in OPEN.
B .False. Redo logs open in OPEN.
C .False. PFILE/SPFILE is read at NOMOUNT.
D .False. SGA is allocated at NOMOUNT.
E .True. Alert log records mount event.
F .True. Control files are read in MOUNT.
NEW QUESTION # 64
Which three statements are true about UNDO and REDO?
- A. REDO is used for instance recovery.
- B. UNDO is used for read consistency.
- C. UNDO is used for some flashback operations.
- D. Both REDO and UNDO can be multiplexed.
- E. REDO is used for read consistency.
- F. REDO is used for ROLLBACK.
Answer: A,B,C
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 # 65
You execute the SHUTDOWN ABORT command. Which two statements are true?
- A. A checkpoint is written.
- B. Data files are closed normally.
- C. Uncommitted transactions are not rolled back by the shutdown.
- D. Subsequent instance startup performs media recovery.
- E. Subsequent instance startup performs instance recovery.
Answer: C,E
Explanation:
A .False. No checkpoint occurs with ABORT.
B .False. Instance recovery, not media recovery, is needed.
C .True. Crash recovery rolls back uncommitted changes on startup.
D .False. Files aren't closed cleanly with ABORT.
E .True. Shutdown doesn't roll back; recovery does.
NEW QUESTION # 66

- F. Automatic Backups of the database system files.
Answer: C,D,E
Explanation:
A .False. Backups are via RMAN, not AMTs.
B .True. Stats collection is an AMT.
C .False. Error logging isn't an AMT.
D .True. SPM tasks are included.
E .False. Notifications aren't AMTs.
F .True. Segment Advisor is an AMT.
NEW QUESTION # 67
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?
- A. Analysis of privileges that a user has on their own schema objects that they did not use.
- B. Analysis of privileges granted indirectly to a role that are then used by a user who has beengranted that role.
- C. Analysis of all privileges used by all users including administrative users in the database.
- D. Analysis of privileges granted directly to a role that are then used by a user who has been granted that role.
- E. Analysis of privileges that a user has on their own schema objects that they did use.
- F. Analysis of all privileges used by all users but excluding administrative users in the database.
Answer: A,B,E
Explanation:
A .True. Captures unused self-owned object privileges.
B .False. SYS is excluded from capture.
C .False. No exclusion option for admin users.
D .False. Direct role grants aren't separately analyzed.
E .True. Tracks indirect role privileges used.
F .True. Identifies used self-owned privileges.
NEW QUESTION # 68
Which two statements are true about the configuration and use of UNDO?
- A. UNDO_RETENTION specifies for how long Oracle attempts to keep expired and unconsumed UNDO.
- B. Active UNDO is always retained.
- C. Unexpired UNDO is always retained.
- D. UNDO_RETENTION specifies for how long Oracle attempts to keep unexpired UNDO.
- E. UNDO_RETENTION specifies how long all types of UNDO are retained.
Answer: B,D
NEW QUESTION # 69
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_CREATE_FILE_DEST specifies a location with at least 100 MB of available space.
- B. Ensure that DB_RECOVERY_FILE_DEST and DB_CREATE_FILE_DEST each specify locations with at least 50 MB of available space.
- C. Specify a path in the DATAFILE clause of the command specifying a location with at least 100 MB of available space.
- D. Add the AUTOEXTEND ON clause with NEXT set to 100M.
- E. Ensure that DB_RECOVERY_FILE_DEST and DB_CREATE_FILE_DEST each specify locations with at least 50 MB of available space.
Answer: A,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 # 70
Which two statements are true about the PMON background process?
- A. It frees resources held by abnormally terminated processes.
- B. It records checkpoint information in the control file.
- C. It rolls back transactions when a process fails.
- D. It frees unused temporary segments.
- E. It registers database services with all local and remote listeners known to the database instance.
Answer: A,C
Explanation:
A .False. LREG handles registration in 23ai, not PMON.
B .False. CKPT (Checkpoint) process updates the control file.
C .True. PMON cleans up after failed processes (e.g., releases locks).
D .True. PMON rolls back uncommitted transactions of failed processes.
E .False. SMON (System Monitor) manages temporary segment cleanup.
NEW QUESTION # 71
Which statement is true about database links?
- A. A public database link can be used by any user allowing remote database instance connection for selecting schema data.
- B. A public database link can be created only by SYS.
- C. A database link created in a database allows a connection from that database's instance to the target database's instance for selecting schema data.
- D. Private database link creation requires the same user to exist in both the local and the remote databases.
- E. A database link can be created only between two Oracle databases.
Answer: C
Explanation:
A .False. Links can connect to non-Oracle DBs via gateways.
B .False. No such user requirement; authentication is separate.
C .False. Any user with CREATE PUBLIC DATABASE LINK can create one.
D .True. Links enable remote schema access (e.g., SELECT * FROM emp@remote).
E .False. Public links allow access, but privileges on remote objects are needed.
NEW QUESTION # 72
