第4题：

You performed an incomplete recovery and opened the database with the RESETLOGS option. The LOG_ARCHIVE_FORMAT parameter is set to ’ora_%t_%s_%r.log’.  Which statement regarding the archived redo log files， created in an earlier incarnation of the database，is true？（）

• A、 The archived redo log files will be overwritten.

• C、 The archived redo log files should be moved to some other location.
• D、 The archived redo log files are still maintained because the file names are unique.

第5题：

You configured the Flash Recovery Area for your database. The database instance has been started inARCHIVELOG mode and the LOG_ARCHIVE_DEST_1 parameter is not set. What will be the implications onthe archiving and the location of archive redo log files（）

• A、Archiving will be disabled because the destination for the redo log files is missing.
• B、The database instance will shut down and the error details will be logged in the alert log file.
• C、Archiving will be enabled and the destination for the archived redo log file will be set to the Flash RecoveryArea implicitly.
• D、Archiving will be enabled and the location for the archive redo log file will be created in the default location$ORACLE_HOME/log.

第6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.
