第1题：

You have configured flash recovery area in your database and you set the following Initialization parameters for your database instance：   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_I 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.

第2题：

The database is running in ARCHIVELOG mode. Examine the initialization parameters and theirvalues set to enable archiving on your database server：  LOG_ARCHIVE_FORMAT = arch_%t_%s_%r.arc  LOG_ARCHIVE_DEST_1 = ’LOCATION = /disk1/archive’  DB_RECOVERY_FILE_DEST = ’/u01/oradata’  DB_RECOVERY_FILE_DEST_SIZE = 20G  Which statement is true regarding the archived redo log files（）

• A、It will be created on the local file system.
• B、It will be created only in the Flash Recovery Area.
• C、It will be created in the location specified by the LOG_ARCHIVE_DEST_1 parameter and the defaultlocation $ORACLE_HOME/dbs.
• D、It will be created in the location specified by the LOG_ARCHIVE_DEST_1 parameter and locationspecified by the DB_RECOVERY_FILE_DEST parameter.

• A、The MANDATORY location must be a flash recovery area.
• B、The optional destinations may not use the flash recovery area.
• C、This setting is not allowed because the first destination is not set as MANDATORY.
• D、The online redo log file is not allowed to be overwritten if the archived log cannot be created in the fourth destination.
