An xSeries specialist monitors a customer’s server that has poor performance.  The customer is running an x365 with a ServeRAID 6i controller with write-back cache turned on and ten 15K rpm drives in a RAID-5 array.  It is a mission-critical server and must have a redundant storage system.  Performance tests indicate that the Average Disk sec/Transfer exceeds 20 ms.  Which of the following is the lowest-cost method to increase the throughput？（）

• A、Disable the ServRAID cache
• B、Change the RAID level to 10
• C、Change the cache level to Write Through
• D、Add five more drives to the array to increase the number of read/write heads

第9题：

You are administering a database stored in Automatic Storage Management (ASM). You use RMAN to back up the database and the MD_BACKUP command to back up the ASM metadata regularly. You lost an ASM disk group DG1 due to hardware failure. In which three ways can you re-create the lost disk group and restore the data?（）

• A、Use the MD_RESTORE command to restore metadata for an existing disk group by passing the existing disk group name as an input parameter and use RMAN to restore the data.
• B、Use the MKDG command to restore the disk group with the same configuration as the backed-up disk group and data on the disk group.
• C、Use the MD_RESTORE command to restore the disk group with the changed disk group specification, failure group specification, name, and other attributes and use RMAN to restore the data.
• D、Use the MKDG command to restore the disk group with the same configuration as the backed-up disk group name and same set of disks and failure group configuration, and use RMAN to restore the data.
• E、Use the MD_RESTORE command to restore both the metadata and data for the failed disk group.
• F、Use the MKDG command to add a new disk group DG1 with the same or different specifications for failure group and other attributes and use RMAN to restore the data.
