Oracle Database 23ai Administration Associate Sample Questions (Q30-Q35):

NEW QUESTION # 30
Which of the following ALTER SYSTEM statements can be run from within a pluggable database (PDB)?

  • A. ALTER SYSTEM SWITCH LOGFILE
  • B. ALTER SYSTEM CHECKPOINT
  • C. ALTER SYSTEM FLUSH BUFFER_CACHE
  • D. ALTER SYSTEM ENABLE / DISABLE RESTRICTED SESSION

Answer: B,D

Explanation:
A .True. Local checkpoints are allowed in PDBs.
B .False. Buffer cache is CDB-level.
C .False. Log switching is CDB-level.
D .True. Restricted session can be toggled per PDB.


NEW QUESTION # 31
Which three actions are ways to apply the principle of least privilege?

  • A. Enabling Unified Auditing.
  • B. Setting the O7_DICTIONARY_ACCESSIBILITY parameter to TRUE.
  • C. Using Access Control Lists (ACLs).
  • D. Revoking execute privilege on UTL_SMTP, UTL_TCP, UTL_HTTP, and UTL_FILE from the roles/users (assuming typo for duplicate option).
  • E. Setting the REMOTE_OS_AUTHENT parameter to TRUE.

Answer: A,C,D

Explanation:
A .True. Auditing tracks privilege use, enforcing least privilege.
B .True. Revoking unnecessary PL/SQL access limits capabilities.
C .True. ACLs restrict network access precisely.
D .False. TRUE relaxes dictionary access, violating least privilege.
E .False. TRUE allows risky OS auth, weakening security.


NEW QUESTION # 32
How do you validate that the database was migrated to Unified Auditing?

  • A. By querying V$OPTION for parameter Unified Auditing.
  • B. By querying the DBA_UNIFIED_AUDIT_OPTION view.
  • C. By executing DBMS_AUDIT_MGMT PL/SQL package in Verify mode.
  • D. By using the LSINVENTORY Command to query the Oracle Database Software Library.

Answer: A

Explanation:
Unified Auditing is enabled at database creation or migration in 23ai. Let's analyze:
A . By querying V$OPTION for parameter Unified Auditing.
True. SELECT VALUE FROM V$OPTION WHERE PARAMETER = 'Unified Auditing'; returns TRUE if enabled. It's the definitive way to confirm Unified Auditing is active at the database level.
Mechanics:V$OPTION reflects compiled-in features; TRUE indicates the binary was linked with Unified Auditing (uniauflt=on during relink).
Practical Use:Quick, reliable check post-migration or upgrade.
B . By using the LSINVENTORY Command to query the Oracle Database Software Library.
False. LSINVENTORY (from OPatch) lists installed software components, not runtime features like auditing mode.
C . By querying the DBA_UNIFIED_AUDIT_OPTION view.
False. This view doesn't exist; DBA_AUDIT_POLICIES or UNIFIED_AUDIT_TRAIL show policies and records but not migration status.
D . By executing DBMS_AUDIT_MGMT PL/SQL package in Verify mode.
False. No "Verify mode" exists in DBMS_AUDIT_MGMT; it manages audit trails, not migration validation.


NEW QUESTION # 33
Which three statements are true about UNDO and REDO?

  • A. Both REDO and UNDO can be multiplexed.
  • B. UNDO is used for read consistency.
  • 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: B,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 # 34
Which of the following statements is true about external tables?

  • A. They are read/write tables.
  • B. They describe how data is stored in the external source.
  • C. They describe how the external table layer presents data to the server.
  • D. They describe data stored in the database.

Answer: C

Explanation:
A .False. External tables are read-only.
B .True. Defines how external data (e.g., CSV) is mapped to SQL.
C .False. Data is external, not in the DB.
D .False. Storage is external; Oracle doesn't define it.
