Which two dynamic performance views can you use to identify files that need to be backed up, regardless of whether you are in ARCHIVELOG mode or NOARCHIVELOG mode?

Answer: D

Explanation: The view V$DATAFILE contains all datafiles and V$CONTROLFILE contains a list of all copies of the control file. A is wrong because you do not need to back up the online redo log files. B is wrong because you do not need to back up datafiles from temporary tablespaces , which do not contain any permanent objects, and can be easily re-created if lost. C is wrong because online redo log files do not need to be backed up and V$LOG contains information about online redo log file groups, not individual files.
