Oracle Database 23ai Administration Associate Sample Questions (Q41-Q46):

NEW QUESTION # 41
Which two statements are true about views used for viewing tablespace and datafile information?

A. V$TABLESPACE displays information that is contained in the control file about tablespaces.
B. V$TABLESPACE displays information about tablespaces contained in the data dictionary.
C. Tablespace free space can be viewed in V$TABLESPACE.
D. Tablespace free space can be viewed in DBA_TABLESPACES.
E. A datafile can be renamed when the database is in MOUNT state and the new file name is displayed when querying DBA_DATA_FILES after the database is opened.

Answer: A,E

Explanation:
A .False. V$TABLESPACE doesn't show free space directly.
B .False. It's from the control file, not the data dictionary.
C .True. Renaming in MOUNT state updates DBA_DATA_FILES post-open.
D .False. DBA_TABLESPACES shows attributes, not free space directly (use DBA_FREE_SPACE).
E .True. V$TABLESPACE reflects control file data.

NEW QUESTION # 42
Which two statements describe why Database Auditing is a security requirement?

A. To monitor suspicious activity.
B. To protect against data corruption.
C. To monitor proper usage of the system and data by privileged users.
D. To protect against data theft by a non-authorized user.
E. To alert DBAs about system issues.

Answer: A,C

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 # 43
What are Oracle Database Metrics?

A. Oracle Database Metrics are a set of statistics built in Oracle Enterprise Manager Cloud Control and used for automation.
B. Oracle Database Metrics monitor performance using thresholds to generate alerts.
C. Oracle Database Metrics are a set of measured statistics per unit of time (per second), transaction, or sessions that are used to evaluate performance.
D. Oracle Database Metrics are part of the Oracle Database Notification system to email information about major database events.
E. Oracle Database Metrics are part of Oracle Enterprise Manager Cloud Control's Notification system used to email alerts.

Answer: B,C

Explanation:
A .True. Metrics (e.g., V$SYSMETRIC) use thresholds for alerts.
B .False. Metrics aren't tied to email notifications directly.
C .True. Metrics measure rates (e.g., IOPS, transactions/sec).
D .False. EMCC uses metrics, but they're DB-level, not EM-specific.
E .False. Metrics exist in the DB, not just EMCC.

NEW QUESTION # 44
Which three statements are true about roles?

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

Answer: A,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.
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 # 45
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. The PDB must be opened Read Only to complete the integration of the PDB into the CDB.
B. After the PDB is created, it is automatically opened Read/Write.
C. It creates tablespaces to store metadata.
D. It creates a new local user ADMIN with SYSDBA privileges.
E. It creates new default schemas for the PDB.
F. It creates a new local user ADMIN with restricted privileges.

Answer: C,E,F

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.
