LOG_ARCHIVE_DEST 1='LOCATION=/disk1/arch MANDATORY'

LOG_ARCHIEVE_DEST 2='LOCATION=/disk2/arch'

LOG_ARCHIVK_DEST_3='LOCATION=/diSk3/arch'

LOG_ARCH1VK_DEST_4='LOCATION=/disk4/arch'

LOG_ARCHIVE_MIN_SUCCEED_DEST=2

While the database instance is functional,you realized that

the destination set by the LOG_ARCHIVE_DEST_1 parameter is not available for the archived redo log file to be created in.

All redo log groups have been used.

What happens in an event of log switch?

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.
