Free 1z0-060 Sample Question 18
You database is running an ARCHIVELOG mode.
The following parameter are set in your database instance:
LOG_ARCHIVE_FORMAT = arch+%t_%r.arc
LOG_ARCHIVE_DEST_1 = `LOCATION = /disk1/archive'
DB_RECOVERY_FILE_DEST_SIZE = 50G
DB_RECOVERY_FILE = `/u01/oradata'
Which statement is true about the archived redo log files?
A. They are created only in the location specified by the LOG_ARCHIVE_DEST_1 parameter.
B. They are created only in the Fast Recovery Area.
C. They are created in the location specified by the LOG_ARCHIVE_DEST_1 parameter and in the default location $ORACLE_HOME/dbs/arch.
D. They are created in the location specified by the LOG_ARCHIVE_DEST_1 parameter and the location specified by the DB_RECOVERY_FILE_DEST parameter.
Correct Answer: A
You can choose to archive redo logs to a single destination or to multiple destinations. Destinations can be local--within the local file system or an Oracle Automatic Storage Management (Oracle ASM) disk group--or remote (on a standby database). When you archive to multiple destinations, a copy of each filled redo log file is written to each destination. These redundant copies help ensure that archived logs are always available in the event of a failure at one of the destinations. To archive to only a single destination, specify that destination using the LOG_ARCHIVE_DEST and LOG_ARCHIVE_DUPLEX_DEST initialization parameters.
ARCHIVE_DEST initialization parameter. To archive to multiple destinations, you can choose to archive to two or more locations using the LOG_ARCHIVE_DEST_n initialization parameters, or to archive only to a primary and secondary destination using the LOG_ ARCHIVE_DEST and LOG_ARCHIVE_DUPLEX_DEST initialization parameters.
