Oracle Database 23ai Administration Associate Sample Questions (Q35-Q40):

NEW QUESTION # 35
Which data dictionary view describes the data sources of external tables?

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

Answer: A

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 # 36
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. When the DBA revokes the CREATE VIEW privilege from USR1, it is neither revoked from USR2 nor USR3.
  • B. The DBA can revoke only ADMIN OPTION from USR1.
  • C. When the DBA revokes the CREATE VIEW privilege from USR1, it is revoked from USR2 but not USR3.
  • D. When the DBA revokes the CREATE VIEW privilege from USR2, it is revoked from USR3.
  • E. USR1 can revoke the CREATE VIEW privilege from USR3.

Answer: A,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 # 37
Which three statements are true about UNDO and REDO?

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

Answer: A,C,E

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 # 38
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. Specify a path in the DATAFILE clause of the command specifying 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. Add the AUTOEXTEND ON clause with NEXT set to 100M.
  • 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: B,D

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 # 39
Which two statements are true concerning logical and physical database structures?

  • A. A segment might have only one extent.
  • B. A segment's blocks can be of different sizes.
  • C. A segment can span multiple data files in some tablespaces.
  • D. A segment's blocks can be of different sizes.
  • E. All tablespaces may have one or more data files.
  • F. Segments can span multiple tablespaces.

Answer: A,C

Explanation:
False. All blocks in a segment use the tablespace's block size (e.g., 8KB). While a database can have tablespaces with different block sizes (e.g., 8KB, 32KB), a single segment's blocks are uniform, as it resides in one tablespace.
Explanation:
Logical structures (e.g., segments, extents) map to physical structures (e.g., data files, blocks). Let's dissect each option:
A : A segment can span multiple data files in some tablespaces.
True. A segment (e.g., a table or index) is a logical entity stored in a tablespace. In a smallfile tablespace (default in Oracle), a segment's extents can span multiple data files if the tablespace has multiple files and space allocation requires it. This is common in large tables or when autoextend adds new files.
Mechanics:Oracle allocates extents across available data files in a round-robin fashion (with ASSM) or as needed, ensuring the segment's data is distributed. This doesn't apply to bigfile tablespaces, which use a single data file.
Example:A 10GB table in a tablespace with two 5GB data files will span both.
B : Segments can span multiple tablespaces.
False. A segment is confined to a single tablespace. Oracle enforces this to maintain logical separation (e.g., a table's data stays in its assigned tablespace). Partitioned tables can have partitions in different tablespaces, but each partition is a separate segment.
Why Not:The segment header and extent map reside in one tablespace, preventing cross-tablespace spanning for a single segment.
C : A segment might have only one extent.
True. A segment starts with one extent upon creation (e.g., a small table or index). If no further growth occurs, it remains a single-extent segment. This is common with small objects or when INITIAL extent size suffices.
Mechanics:In locally managed tablespaces (default), the initial extent is allocated based on INITIAL or tablespace defaults (e.g., 64KB), and additional extents are added only as needed.
D : All tablespaces may have one or more data files.
False. Bigfile tablespaces are restricted to one data file (up to 128TB). Smallfile tablespaces (traditional) can have multiple data files (up to 1022), but the "all" phrasing makes this false due to bigfile exceptions.
Clarification:The question's intent may assume smallfile tablespaces, but Oracle 23ai supports both types.
