Not D – If there is not enough disk space to grow, then DBUA prompts you to create space by adding more data files. DBUA does not automatically add new data files, because DBUA cannot determine where to create the files.
Not C – Be aware that the upgrade process itself does not automatically enable unified auditing. You must manually migrate to unified auditing,
not A – The resources that generally require increases for a new Oracle Database release are as follows:
• SYSTEM and SYSAUX tablespaces
Typically if your SYSTEM tablespace size is insufficient, you receive an error message during the upgrade.
