第6题：

You are using an Automatic Storage Management （ASM） instance to manage the database files of your production database. After adding a new disk group to the ASM instance， you execute the following command：  ALTER DISKGROUP dg3 REBALANCE POWER 0； What would be the result of this command？（）

• A、The rebalancing of the disk group would be stopped.
• B、The rebalancing of the disk group would be completed as fast as possible.
• C、The command would result in an error because the value of POWER cannot be 0.
• D、The rebalancing of the disk group would be completed without affecting the disk group DG3.
• E、The command would result in an error because the disk groups cannot be manually rebalanced.

第7题：

You are using an Automatic Storage Management （ASM） instance to manage the files of your production database. You have two disk groups， DG1 and DG2， with one device each. In the parameter file of the production database， the following parameters have been specified： DB_CREATE_ONLINE_LOG_DEST_1 = ’+dg1’  DB_CREATE_ONLINE_LOG_DEST_2 = ’+dg2’  What would be the impact of this setting？（）

• A、When a new log group is added， it would have one member in each disk group.
• B、When a new log group is added， it would have two members in each disk group.
• C、When a new tablespace is added， it would have one data file in each disk group.
• D、When a new log file is added， it would have one member spread across the disk groups.
