Q4. Your multitenant container database (CDB) contains pluggable databases (PDBs), you are connected to the HR_PDB. You execute the following command:
SQL > CREATE UNDO TABLESPACE undotb01

What is the result?
A. It executes successfully and creates an UNDO tablespace in HR_PDB.
B. It falls and reports an error because there can be only one undo tablespace in a CDB.
C. It fails and reports an error because the CONTAINER=ALL clause is not specified in the command.
D. It fails and reports an error because the CONTAINER=CURRENT clause is not specified in the command.
E. It executes successfully but neither tablespace nor the data file is created.
Answer: E
