A

 The online redo log file Is not allowed to be overwritten.

B

 The archived redo log files are written to the flash recovery area until the MANDATORY destination is made available.

C

 The database instance will crash because the archived redo log file cannot be created in a destination set as MANDATORY.

D

 The destination set by the LOG_ARCHIVE_DEST_1 parameter is ignored and the archived redo log files are created in the next two available locations to guarantee archive log success.
