Oracle Database 23ai Administration Associate Sample Questions (Q78-Q83):

NEW QUESTION # 78
Which three statements are true about Deferred Segment Creation in Oracle databases?

  • A. It is the default behavior for tables and indexes.
  • B. It is supported for Index Organized Tables (IOTs) contained in locally managed tablespaces.
  • C. It is supported for SYS-owned tables contained in locally managed tablespaces.
  • D. Sessions may dynamically switch back and forth from DEFERRED to IMMEDIATE segment creation.
  • E. Indexes inherit the DEFERRED or IMMEDIATE segment creation attribute from their parent table.

Answer: A,D,E

Explanation:
A .False. IOTs require immediate segment creation.
B .False. SYS-owned tables don't use deferred creation.
C .True. Default since 11gR2, continued in 23ai.
D .True. Indexes inherit this attribute unless overridden.
E .True. Sessions can alter this via DEFERRED_SEGMENT_CREATION.


NEW QUESTION # 79
Which two statements describe why Database Auditing is a security requirement?

  • A. To alert DBAs about system issues.
  • B. To monitor proper usage of the system and data by privileged users.
  • C. To protect against data corruption.
  • D. To monitor suspicious activity.
  • 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 # 80
Which three Oracle database space management features will work with both Dictionary and Locally managed tablespaces?

  • A. Capacity planning growth reports based on historical data in the Automatic Workload Repository (AWR).
  • B. Online table segment shrink.
  • C. Online index segment shrink.
  • D. Automatic data file extension (AUTOEXTEND).
  • E. Oracle Managed Files (OMF).

Answer: A,D,E

Explanation:
Dictionary-managed tablespaces (DMTs) use the data dictionary for extent management, whilelocally managed tablespaces (LMTs) use bitmaps. Let's evaluate compatibility:
A . Capacity planning growth reports based on historical data in the Automatic Workload Repository (AWR).
True. AWR tracks space usage (e.g., DBA_HIST_TBSPC_SPACE_USAGE) regardless of tablespace type, enabling growth reports for both DMTs and LMTs.
Mechanics:MMON collects metrics like segment growth, stored in SYSAUX, accessible via EM or scripts.
Practical Use:Helps predict when to add data files, universal across management types.
B . Online table segment shrink.
False. ALTER TABLE ... SHRINK SPACE requires LMTs with Automatic Segment Space Management (ASSM), unavailable in DMTs, which lack bitmap-based free space tracking.
Why Incorrect:DMTs use freelists, incompatible with shrink operations.
C . Online index segment shrink.
False. Like tables, ALTER INDEX ... SHRINK SPACE requires LMTs with ASSM, not supported in DMTs.
Why Incorrect:Same limitation as B; DMTs can't compact online.
D . Oracle Managed Files (OMF).
True. OMF automates file naming and placement (via DB_CREATE_FILE_DEST) for both DMTs and LMTs, agnostic to extent management.
Mechanics:Example: CREATE TABLESPACE ts1; creates an OMF file in either type.
Edge Case:DMTs are rare in 23ai, but OMF still applies.
E . Automatic data file extension (AUTOEXTEND).
True. AUTOEXTEND ON allows data files to grow as needed, supported in both DMTs and LMTs since early versions.
Mechanics:ALTER DATABASE DATAFILE ... AUTOEXTEND ON NEXT 100M; works universally.


NEW QUESTION # 81
You execute this command: CREATE BIGFILE TABLESPACE big_tbs DATAFILE '/u01/oracle/data/big_f1.dbf' SIZE 20G; Sufficient storage is available in filesystem /u01. Which two statements are true about the BIG_TBS tablespace?

  • A. Additional data files may not be added.
  • B. It will always have a 32K blocksize.
  • C. It must be bigger than the largest SMALLFILE tablespace.
  • D. AUTOEXTEND is possible for the datafile.
  • E. It will be a dictionary-managed tablespace by default.

Answer: A,D

Explanation:
A .False. LMT is default in 23ai.
B .True. Bigfile tablespaces have one data file only.
C .True. AUTOEXTEND works with bigfile data files.
D .False. Block size defaults to DB_BLOCK_SIZE (e.g., 8K).
E .False. No size comparison requirement.


NEW QUESTION # 82
Which three statements are true about Oracle Managed Files (OMF)?

  • A. 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.
  • B. If only DB_CREATE_FILE_DEST is specified, only data files and temp files are Oracle managed.
  • C. If DB_RECOVERY_FILE_DEST is specified, at least two different locations must be specified for DB_CREATE_ONLINE_LOG_DEST_n.
  • D. 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.
  • E. 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.
  • F. If only DB_CREATE_ONLINE_LOG_DEST_1 is specified, only redo logs and control files are Oracle Managed.

Answer: A,D,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.
