Which is not a valid way of backing up a control file?
A.
Backing up the control file to trace
B.
Copying the existing control file of the database to the backup location during a hot backup
C.
Copying the existing control file of the database to the backup location during a cold backup
D.
Creating a backup control file
E.
Using the create controlfile command
Why E is correct? “create controlfile command” is used to [RE]CREATE controlfile (using previously created script from “ALTER DATABASE BACKUP CONTROLFILE TO TRACE” command for example), but not to backup it.
E is correct if A is correct…
