Oracle Database 23ai Administration Associate Sample Questions (Q44-Q49):

NEW QUESTION # 44
Which resource plan is used to manage the resources for the predefined maintenance window?

A. By default, all predefined maintenance windows use the DEFAULT_MAINTENANCE_PLANresource plan, and automated maintenance tasks run under subplan called ORA$AUTOTASK.
B. The resources used by the predefined maintenance window can only be adjusted if you create a new resource plan in Resource Manager ...
C. The SYS_GROUP consumer resource group policies define the resources assigned ...
D. The predefined maintenance window starts automatically with 20% of the system resources ...

Answer: A

Explanation:
A .True. Oracle 23ai uses DEFAULT_MAINTENANCE_PLAN with ORA$AUTOTASK subplan for maintenance tasks (e.g., stats gathering). Others are incorrect or speculative.

NEW QUESTION # 45
Which two tasks can you perform using DBCA for databases?

A. Change the standard block size of an existing database.
B. Configure a nonstandard block size for a new database.
C. Enable flashback database for an existing database.
D. Configure incremental backups for a new database.
E. Register a new database with an available Enterprise Manager Management server.

Answer: B,E

Explanation:
A .False. Backups are configured via RMAN, not DBCA.
B .True. DBCA allows nonstandard block sizes during DB creation.
C .True. DBCA can register new DBs with EM.
D .False. Block size is fixed post-creation.
E .False. Flashback is enabled via SQL, not DBCA for existing DBs.

NEW QUESTION # 46
Which three statements are true about roles?

A. All roles granted to a user are set on default when the user logs in.
B. Roles may be granted to other roles.
C. Object privileges may not be granted to roles.
D. Roles must be password protected.
E. The SET ROLE statement can enable one or more roles for a session.
F. The SET ROLE statement can disable one or more roles for a session.

Answer: B,E,F

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.
Mechanics:Password-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 actions are ways to apply the principle of least privilege?

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

Answer: A,D,E

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 # 48
In which two ways would you disable timing information collected for wait events and much of the performance monitoring capability of the database?

A. By setting the TIMED_STATISTICS_LEVEL system parameter to FALSE.
B. By executing the PL/SQL procedure DBMS_TIME_STATISTIC.DISABLE(TRUE).
C. By setting the STATISTICS_LEVEL parameter to BASIC.
D. By executing the PL/SQL procedure DBMS_TIME_STATISTIC.LEVEL(BASIC).
E. By setting the TIMED_STATISTICS system parameter to FALSE.

Answer: C,E

Explanation:
A .True. TIMED_STATISTICS = FALSE disables timing data collection.
B .False. No such procedure exists.
C .False. No TIMED_STATISTICS_LEVEL parameter exists.
D .True. STATISTICS_LEVEL = BASIC disables most performance monitoring.
E .False. No such procedure exists.
