What happens at the next log switch?

Your database is running in archivelog mode. Examine the parameters for your database instance:
LOG_ARCHIVE_DEST_l =’LOCATION=/disk1/arch MANDATORY’
LOG_ARCHIVE_DEST_2 =’LOCATION=/disk2/arch’
LOG_ARCHIVE_DEST_3 =’LOCATIO=/disk3/arch’
LOG_ARCHIVE_DEST _4 =’LOCATIONs/disk4/arch’
LOG_ARCHIVE _MIN_SUCCEED_DEST = 2
While the database is open, you notice that the destination set by the log_archive_dest_1 parameter is not
available. All redo log groups have been used.

A.
The database instance hangs and the redo log files are not overwritten.

B.
The archived redo log files are written to the fast recovery area until the mandatory destination is made
available.

C.
The database instance is shutdown immediately.

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