Oracle Database 23ai Administration Associate Sample Questions (Q34-Q39):

NEW QUESTION # 34
Which two statements are true concerning logical and physical database structures?

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

Answer: A,F

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.

NEW QUESTION # 35
Which two statements are true about views used for viewing tablespace and datafile information?

A. 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.
B. Tablespace free space can be viewed in V$TABLESPACE.
C. Tablespace free space can be viewed in DBA_TABLESPACES.
D. V$TABLESPACE displays information that is contained in the control file about tablespaces.
E. V$TABLESPACE displays information about tablespaces contained in the data dictionary.

Answer: A,D

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.

NEW QUESTION # 36
What are Oracle Database Metrics?

A. Oracle Database Metrics are a set of measured statistics per unit of time (per second), transaction, or sessions that are used to evaluate performance.
B. Oracle Database Metrics are part of the Oracle Database Notification system to email information about major database events.
C. Oracle Database Metrics are part of Oracle Enterprise Manager Cloud Control's Notification system used to email alerts.
D. Oracle Database Metrics are a set of statistics built in Oracle Enterprise Manager Cloud Control and used for automation.
E. Oracle Database Metrics monitor performance using thresholds to generate alerts.

Answer: A,E

Explanation:
A .True. Metrics (e.g., V$SYSMETRIC) use thresholds for alerts.
B .False. Metrics aren't tied to email notifications directly.
C .True. Metrics measure rates (e.g., IOPS, transactions/sec).
D .False. EMCC uses metrics, but they're DB-level, not EM-specific.
E .False. Metrics exist in the DB, not just EMCC.

NEW QUESTION # 37
Examine this command: SQL> ALTER TABLE ORDERS SHRINK SPACE COMPACT; Which two statements are true?

A. The SHRINK operation causes rows to be moved to empty space starting toward the end of the ORDERS segment.
B. The SHRINK operation causes rows to be moved to empty space starting from the beginning of the ORDERS segment.
C. Dependent indexes become UNUSABLE.
D. Queries and DML statements are allowed on ORDERS while the SHRINK is executing.
E. Only queries are allowed on ORDERS while SHRINK is executing.
F. The high-water mark (HWM) of ORDERS is adjusted.

Answer: B,D

Explanation:
A . Dependent indexes become UNUSABLE.False. SHRINK SPACE COMPACT does not affect index usability; only SHRINK SPACE without COMPACT may require index maintenance if CASCADE is omitted.
B . ... starting toward the end of the ORDERS segment.False. Rows are compacted toward the beginning of the segment, not the end.
C . Only queries are allowed ...False. Both queries and DML are allowed during SHRINK SPACE COMPACT as it's an online operation.
D . The high-water mark (HWM) of ORDERS is adjusted.False. COMPACT moves rows but doesn't adjust the HWM; the full SHRINK SPACE command is needed for HWM adjustment.
E . Queries and DML statements are allowed ...True. This is an online operation in 23ai, allowing concurrent access.
F . ... starting from the beginning of the ORDERS segment.True. Rows are moved to fill free space from the segment's start.

NEW QUESTION # 38
Which two actions can you perform using DBCA for an existing database?

A. Create an additional listener.
B. Change the server mode from dedicated to shared, and vice versa.
C. Create a template that can be used to clone the database.
D. Change the character set.
E. Create nonstandard block size tablespaces.

Answer: B,C

Explanation:
A .False. DBCA can't change character sets post-creation.
B .False. Listeners are managed via NetCA or lsnrctl.
C .True. DBCA can switch server modes for existing DBs.
D .False. Tablespaces are created via SQL, not DBCA for existing DBs.
E .True. DBCA can generate clone templates from existing DBs.
