NEW QUESTION # 32
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. DML may be performed on tables with one or more extents in this data file during the execution of this command.
  • 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. The "TO" clause containing the new file name must be specified even if Oracle Managed Files (OMF) is used.

Answer: B,D

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 # 33
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. When the DBA revokes the CREATE VIEW privilege from USR2, it is revoked 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 USR1, it is neither revoked from USR2 nor USR3.
  • E. USR1 can revoke the CREATE VIEW privilege from USR3.

Answer: A,D

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.
