Oracle Database 23ai Administration Associate Sample Questions (Q43-Q48):NEW QUESTION # 43
Your database instance is started with an SPFILE. A PFILE is also available. You execute this command: ALTER SYSTEM SET DB_CACHE_SIZE=100K; Where does the value change?
  • A. In the SPFILE, PFILE, and memory
  • B. Only in the SPFILE
  • C. In the SPFILE and PFILE
  • D. In the SPFILE and memory
  • E. Only in memory
Answer: D
Explanation:
B .True. Without SCOPE, ALTER SYSTEM defaults to BOTH (memory and SPFILE); PFILE isn't updated unless manually recreated.

NEW QUESTION # 44
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. The high-water mark (HWM) of ORDERS is adjusted.
  • F. Only queries are allowed on ORDERS while SHRINK is executing.
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 # 45
What memory structure caches the data dictionary providing access to all database user processes?
  • A. The Large Pool
  • B. The Shared Pool
  • C. The Java Pool
  • D. The Streams Pool
Answer: B
Explanation:
D .True. The Shared Pool caches data dictionary metadata (e.g., table definitions) in the Library Cache and Dictionary Cache, accessible to all processes. Others serve different purposes (e.g., Large Pool for backups).

NEW QUESTION # 46
Which three statements are true about roles?
  • A. Roles must be password protected.
  • B. All roles granted to a user are set on default when the user logs in.
  • C. The SET ROLE statement can enable one or more roles for a session.
  • D. Roles may be granted to other roles.
  • E. The SET ROLE statement can disable one or more roles for a session.
  • F. Object privileges may not be granted to roles.
Answer: C,D,E
Explanation:
Roles in Oracle manage privileges efficiently. Let's dive into each option:
A . Roles must be password protected.
False. Roles can be password-protected (e.g., CREATE ROLE mgr IDENTIFIED BY secret), but it's optional. Non-protected roles (default) are enabled automatically if granted, requiring no password.
Mechanicsassword-protected roles need SET ROLE mgr IDENTIFIED BY secret, enhancing security for sensitive privileges.
B . Roles may be granted to other roles.
True. Roles can form hierarchies (e.g., GRANT clerk TO mgr), allowing nested privilege management.
Mechanics:A user with mgr inherits clerk privileges indirectly. Revoking clerk from mgr cascades appropriately.
Practical Use:Simplifies complex privilege structures in large organizations.
C . The SET ROLE statement can enable one or more roles for a session.
True. SET ROLE role1, role2; activates specified roles for the session, assuming they're granted and not password-protected (or password is provided).
Mechanics:Enabled roles grant their privileges immediately within the session scope.
D . Object privileges may not be granted to roles.
False. Object privileges (e.g., GRANT SELECT ON emp TO clerk) are a primary use of roles, making this statement incorrect.
Why Incorrect:Roles are designed for this purpose, contradicting the option.
E . All roles granted to a user are set on default when the user logs in.
False. Only roles marked as DEFAULT ROLE (via ALTER USER ... DEFAULT ROLE role1) are enabled at login. Non-default roles require SET ROLE.
Mechanics:Check via SELECT * FROM DBA_ROLE_PRIVS WHERE DEFAULT_ROLE='YES'.
F . The SET ROLE statement can disable one or more roles for a session.
True. SET ROLE NONE disables all roles, or SET ROLE role1 implicitly disables others not listed, providing granular control.
Practical Use:Useful for testing or restricting privileges temporarily.

NEW QUESTION # 47
Which three statements are true about resumable space allocation in Oracle databases?
  • A. Resumable space allocation is only possible with locally managed tablespaces.
  • B. The AFTER SUSPEND event trigger can itself be suspended due to space conditions.
  • C. A user's session may be suspended and resumed multiple times.
  • D. All sessions must have the same timeout value when waiting for resumable space allocations.
  • E. A user's session may be suspended even if the user has the UNLIMITED TABLESPACE system privilege.
  • F. Resumable space allocation may be enabled for some sessions and not others.
Answer: C,E,F
Explanation:
A .True. Enabled per session with ALTER SESSION ENABLE RESUMABLE.
B .True. Multiple suspensions can occur in one session.
C .False. Works with dictionary-managed tablespaces too.
D .False. Timeout is session-specific.
E .True. Privilege doesn't prevent suspension; quota limits do.
F .False. Triggers execute but can't suspend themselves.
