Archive file format LOG_ARCHIVE_FORMAT is defined as arch_%s.arc. A week ago， you just archived arch_4.arch to tape， then removed all archived files to save disk space. Yesterday you saw arch_10.arc and arch_11.arc on the disk. Today， you see arch_3.arc in the archive directory. Which two could you happened？（）A、Redo logs were restored from tape for recovery. B、The file names are only used when they are copied to tape. C、The database was opened with the RESETLOGS option and log numbers restarted. D、Log names run in circular fashion; arch_3.arc is re-created by the ARCn process. E、A file name is randomly chosen by the archive process; as long as it is unique, it does not have to be sequential.
In your database， you may be forced to perform a recovery using the RESETLOGS option during which the redo logs would be reset to sequence number 1. You want to avoid the overwriting of old log files. Which archived log file name format ensures this？ （）A、%t_%s.dbfB、arch_%t.arcC、arch_%d.arcD、arch_%t_%d.arcE、arch_%d_%s_.dbfF、arch_%t_%s_%r.arc
