NEW QUESTION # 102
For which two requirements can you use the USER_TABLESPACEclause with the CREATE PLUGGABLE DATABASEcommand? (Choose two.)

• A. to specify the list of user tablespaces to include when moving a non-CDB to a PDB
• B. to specify a default tablespace in a PDB cloned from another PDB in the same CDB.

• D. to include specific user tablespaces only when relocating a PDB
• E. to exclude all tablespaces except SYSTEM, SYSAUX, and TEMP when plugging in a PDB
• F. to specify the list of tablespaces to include when creating a PDB from the CDB seed

Answer: A,F

Explanation:
A - False : When you create the PDB from the PDB seed or an application seed and specify the DEFAULT TABLESPACE clause, Oracle Database creates a smallfile tablespace and sets it as the default tablespace for the PDB.
B, E - False : Specify ALL EXCEPT to include all tablespaces, except for the tablespaces listed.
This clause does not apply to the SYSTEM, SYSAUX, or TEMP tablespaces. Do not include these tablespaces in a tablespace list for this clause.
C - False : This clause can be used to specify user tablespaces when cloning, creating, or relocating a PDB D - True : For example, when you move a non-CDB to a PDB, and the non-CDB had several schemas that each supported a different application, you can use this clause to separate the data belonging to each schema into a separate PDB. This technique assumes that each schema used a separate tablespace in the non-CDB.
F - True : The USER_TABLESPACES clause of the CREATE PLUGGABLE DATABASE statement specifies which tablespaces are available in the new PDB. List one or more tablespaces to include.
