You are using RMAN to back up your database. All the data files are in read/write mode.
Examine the RMAN configuration parameters:
Which two statements are true about a whole consistent backup of a database running in ARCHIVELOG mode?
(Choose two.)
A.
The backup can be used as an incremental level 0 backup.
B.
The database instance must be shut down to take the backup.
C.
The database must be in MOUNT state to take the backup.
D.
The backup consists of blocks that have been formatted.
E.
The system Change Number (SCN) is the same for all the data files in the backup.
The correct answers should be B and C.

I think the answer should be C and E.
B is incorrect if database must be in mount state.
E is correct. The SCN should be the same for all data files.
True. I interpreted B as It requires consistent shutdown.
I agree with Eric, CE
to make a full and consistent backup the database must be in mount state.
Correct answer is C & E.
B is wrong because RMAN cannot locate path of datafile when DB is shutdown (control file has not read yet).
