Oracle Database 23ai Administration Associate Sample Questions (Q28-Q33):

NEW QUESTION # 28
Which three statements are true about roles?

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

Answer: A,C,D

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 # 29
You have connected to the CDB root as a common user with the CREATE PLUGGABLE DATABASE system privilege and issued the following command: SQL> CREATE PLUGGABLE DATABASE pdb1 ADMIN USER admin1 IDENTIFIED BY p1 ROLES = (CONNECT) FILE_NAME_CONVERT = ('PDB$SEEDdir', 'PDB1dir'); Which three are results of the CREATE command?

A. It creates tablespaces to store metadata.
B. It creates new default schemas for the PDB.
C. The PDB must be opened Read Only to complete the integration of the PDB into the CDB.
D. It creates a new local user ADMIN with restricted privileges.
E. It creates a new local user ADMIN with SYSDBA privileges.
F. After the PDB is created, it is automatically opened Read/Write.

Answer: A,B,D

Explanation:
A .True. PDBs inherit default schemas from the seed.
B .True. Metadata tablespaces (e.g., SYSTEM, SYSAUX) are created.
C .False. ADMIN1 (not ADMIN) isn't granted SYSDBA.
D .False. No read-only requirement post-creation.
E .False. PDBs start in MOUNTED state, not open.
F .True. ADMIN1 is a local user with CONNECT role only.

NEW QUESTION # 30
Which two SQL Plan Management Advisor tasks are part of Automatic Maintenance Tasks?

A. The Automatic SQL Plan Management Evolve Advisor task, which evolves plans that have recently been added as the SQL plan baseline for statements.
B. The Automatic Index Advisor task, which is used to create and maintain table indexes based on the DML load and operations.
C. The Automatic SQL Access Advisor task, which is used to manage an application SQL load.
D. The Automatic SQL Tuning Advisor tasks, which would examine the performance of high-load SQL statements and make recommendations for those statements.
E. The Automatic SQL Performance Analyzer task, which is used to provide details about impact of database changes to application SQL batch.

Answer: A,D

Explanation:
Automatic Maintenance Tasks (AMTs) in 23ai optimize database performance. Let's explore:
A .False. SQL Access Advisor exists but isn't an AMT; it's manual or invoked separately.
B .False. SQL Performance Analyzer assesses change impacts but isn't part of AMTs.
C .False. No "Automatic Index Advisor" exists as an AMT; Auto Index is a separate feature.
D .True. The SPM Evolve Advisor task (part of ORA$AUTOTASK) automatically evolves SQL plan baselines, testing and accepting new plans.
Mechanics:Runs in maintenance windows, managed by DBMS_SPM.
E .True. SQL Tuning Advisor (STA) runs automatically via AMTs, tuning high-load SQL.
Mechanics:Identifies candidates from AWR and suggests indexes, profiles, etc.

NEW QUESTION # 31
Which statement regarding PDBs (Pluggable Databases) is correct?

A. When the relocation of a PDB is finished, the source PDB must be dropped.
B. You cannot drop a source PDB of a refreshable PDB.
C. You can drop a PDB as long as it is not the PDB seed.
D. You can drop an application root along with the associated PDBs.

Answer: C

Explanation:
A .True. Any PDB except PDB$SEED can be dropped.
B .False. Source PDBs of refreshable clones can be dropped after cloning.
C .False. Dropping an application root requires explicit handling of PDBs.
D .False. Relocation doesn't mandate dropping the source PDB.

NEW QUESTION # 32
Which of the following ALTER SYSTEM statements can be run from within a pluggable database (PDB)?

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

Answer: A,C

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.
