• Connection interruptions occur

• The data file is restored

What is the assumed scenario when a data file is deleted and no backup is available?

• The database shuts down

• The data file is recreated

What is the final step after removing a PDB with unavailable data files?

• Create a new PDB

• Restart the database

• Backup the remaining data files

• Shut down and start up the CDB

What is the consequence of not having a backup when a PDB data file is deleted?
