D. At the PDB level if the policy is created by a COMMON user.
E. COMMON Unified Audit Policies can only be created at CDB level to monitor DBA operation at any level.

Answer: A,D

B .True. Common policies apply at CDB level.
C .False. Application Root uses app-specific policies.
D .False. "COMMON option" isn't a feature; policies are common by creation context.
E .True. A common user can create policies for PDBs.

NEW QUESTION # 82
Which two statements are true about the DUAL table?

A. It can display multiple rows but only a single column.
B. It can display multiple rows and columns.
C. It can be accessed only by the SYS user.
D. It can be used to display only constants or pseudo columns.
E. It consists of a single row and single column of VARCHAR2 data type.
F. It can be accessed by any user who has the SELECT privilege in any schema.

Answer: E,F

Explanation:
A .True. DUAL is public; any user with SELECT can query it.
B .True. One row, one VARCHAR2 column (DUMMY).
C .False. Fixed at one row.
D .False. Not restricted to SYS.
E .False. One row, one column only.
F .False. Can return expressions, not just constants.

NEW QUESTION # 83
Which three statements are true about an SPFILE?

A. It can be used to create a PFILE.
B. It must exist for a database instance to start.
C. It contains only static initialization parameters.
D. It contains initialization parameters whose values can be changed using the ALTER SYSTEM statement.
E. It can be created by SYS from an idle instance.

Answer: A,D,E

Explanation:
A .True. CREATE SPFILE FROM PFILE works when idle.
B .False. Includes dynamic parameters too.
C .True. CREATE PFILE FROM SPFILE generates a PFILE.
D .False. A PFILE can start the instance if no SPFILE exists.
E .True. Dynamic parameters (e.g., DB_CACHE_SIZE) are modifiable.

E. Unexpired UNDO is always retained.

Answer: B,D

NEW QUESTION # 85
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. It overwrites any existing file with the name sales02.dbf in /u02 by default.
C. DML may be performed on tables with one or more extents in this data file during the execution of this command.
D. The "TO" clause containing the new file name must be specified even if Oracle Managed Files (OMF) is used.
E. Tables with one or more extents in this data file may be queried during the execution of this command.

Answer: C,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.
