Oracle Database 23ai Administration Associate Sample Questions (Q54-Q59):

NEW QUESTION # 54
As the DBA, you execute this command: GRANT CREATE VIEW TO usr1 WITH ADMIN OPTION; USR1 then executes: GRANT CREATE VIEW TO usr2 WITH ADMIN OPTION; USR2 then executes: GRANT CREATE VIEW TO usr3; Which statement is true?

A. USR1 can revoke the CREATE VIEW privilege from USR3.
B. When the DBA revokes the CREATE VIEW privilege from USR1, it is revoked from USR2 but not USR3.
C. The DBA can revoke only ADMIN OPTION from USR1.
D. When the DBA revokes the CREATE VIEW privilege from USR2, it is revoked from USR3.
E. When the DBA revokes the CREATE VIEW privilege from USR1, it is neither revoked from USR2 nor USR3.

Answer: D,E

Explanation:
A .False. Revoking from USR1 doesn't cascade due to WITH ADMIN OPTION.
B .True. Revoking from USR2 cascades to USR3 because USR2 granted it.
C .False. DBA can revoke the full privilege, not just ADMIN OPTION.
D .False. USR1 can't revoke from USR3 directly; only the grantor (USR2) can.
E .True. WITH ADMIN OPTION breaks the revoke chain from USR1 onward.

NEW QUESTION # 55
Which statement is true about database links?

A. A database link created in a database allows a connection from that database's instance to the target database's instance, but not vice versa.
B. A public database link can be used by a user connected to the local database instance to connect to any schema in the remote database instance.
C. A public database link can be created only by SYS.
D. Private database link creation requires the same user to exist in both the local and the remote databases.
E. A database link can be created only between two Oracle databases.

Answer: A

Explanation:
Database links enable cross-database queries in Oracle. Let's analyze each option with extensive detail:
A . A public database link can be created only by SYS.
False. Any user with the CREATE PUBLIC DATABASE LINK privilege (not just SYS) can create a public link (e.g., CREATE PUBLIC DATABASE LINK remote_db CONNECT TO scott IDENTIFIED BY tiger USING 'orcl'). While SYS typically has this privilege, it's not exclusive to SYS.
Mechanics:Privilege is granted via GRANT CREATE PUBLIC DATABASE LINK TO user;. Public links are accessible to all users in the local DB.
Why Incorrect:Overly restrictive; Oracle's security model allows delegation.
B . A database link can be created only between two Oracle databases.
False. Database links can connect to non-Oracle databases using Oracle Heterogeneous Services or gateways (e.g., ODBC or JDBC drivers), such as linking to SQL Server. Example: CREATE DATABASE LINK mssql_link USING 'hsodbc';.
Mechanics:Requires configuration of hs_ parameters in init.ora and a gateway listener.
Historical Note:Heterogeneous links were introduced in 8i, expanded in 23ai for cloud integration.
C . A database link created in a database allows a connection from that database's instance to the target database's instance, but not vice versa.
True. A database link is unidirectional; it enables queries from the local instance to the remote instance (e.g., SELECT * FROM emp@remote_db), but the remote instance can't use it to query back unless a separate link is created there.
Mechanics:Stored in DBA_DB_LINKS, the link defines a one-way connection via a TNS alias or connect string.
Practical Use:Ensures controlled access; bidirectional access requires explicit configuration.
Edge Case:Loops are prevented unless explicitly designed with mutual links.
D . A public database link can be used by a user connected to the local database instance to connect to any schema in the remote database instance.
False. Public links allow all local users to use them, but access to remote schemas depends on the link's credentials (e.g., CONNECT TO scott) and the user's remote privileges. "Any schema" overstates it; access is limited to what the link's user can see.
Why Incorrect:Misrepresents privilege scope; remote schema access isn't universal.
E . Private database link creation requires the same user to exist in both the local and the remote databases.
False. A private link (e.g., CREATE DATABASE LINK my_linkCONNECT TO scott IDENTIFIED BY tiger USING 'orcl') requires the remote user (scott) to exist, but the local creator (e.g., HR) need not match. The link is owned locally and authenticated remotely.
Mechanics:Only the CREATE DATABASE LINK privilege is needed locally.

NEW QUESTION # 56
Examine this command: ALTER DATABASE MOVE DATAFILE '/u01/sales01.dbf' TO '/u02/sales02.dbf'; Which two statements are true?

A. Compressed objects in sales01.dbf will be uncompressed in sales02.dbf after the move.
B. The "TO" clause containing the new file name must be specified even if Oracle Managed Files (OMF) is used.
C. It overwrites any existing file with the name sales02.dbf in /u02 by default.
D. Tables with one or more extents in this data file may be queried during the execution of this command.
E. DML may be performed on tables with one or more extents in this data file during the execution of this command.

Answer: D,E

Explanation:
The ALTER DATABASE MOVE DATAFILE command relocates a data file to a new location while the database remains online, introduced in Oracle 12c and enhanced in subsequent releases like 23ai. Let's evaluate each option:
A . DML may be performed on tables with one or more extents in this data file during the execution of this command.True. The move operation is online by default in Oracle 23ai, allowing DML (INSERT, UPDATE, DELETE) operations on tables within the data file being moved. The database ensures consistency using redo and undo mechanisms.
B . It overwrites any existing file with the name sales02.dbf in /u02 by default.False. By default, the command does not overwrite an existing file unless the REUSE clause is specified (e.g., ALTER DATABASE MOVE DATAFILE ... REUSE). Without it, the command fails if the target file exists.
C . The "TO" clause containing the new file name must be specified even if Oracle Managed Files (OMF) is used.False. When OMF is enabled (via DB_CREATE_FILE_DEST), the TO clause is optional. If omitted, Oracle automatically generates a file name and places it in the OMF destination.
D . Compressed objects in sales01.dbf will be uncompressed in sales02.dbf after the move.False. The move operation is a physical relocation of the data file; it does not alter the logical structure or compression state of objects within it. Compressed data remains compressed.
E . Tables with one or more extents in this data file may be queried during the execution of this command.True. The online nature of the move allows queries (SELECT statements) to proceed without interruption, leveraging Oracle's multi-version consistency model.

NEW QUESTION # 57
You execute the SHUTDOWN ABORT command. Which two statements are true?

A. A checkpoint is written.
B. Subsequent instance startup performs media recovery.
C. Uncommitted transactions are not rolled back by the shutdown.
D. Subsequent instance startup performs instance recovery.
E. Data files are closed normally.

Answer: C,D

Explanation:
A .False. No checkpoint occurs with ABORT.
B .False. Instance recovery, not media recovery, is needed.
C .True. Crash recovery rolls back uncommitted changes on startup.
D .False. Files aren't closed cleanly with ABORT.
E .True. Shutdown doesn't roll back; recovery does.

NEW QUESTION # 58
Which resource plan is used to manage the resources for the predefined maintenance window?

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

Answer: C

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.
