考题
You want to check the EMP table in the user， Scott’s schema for block corruption. You also want to fix the corrupted blocks， if any. How will you accomplish the required task？（）A、by using the ANALYZE utilityB、by using the DBVERIFY utilityC、by using the DB_BLOCK_CHECKING parameterD、by using the DBMS_REPAIR package
考题
In your test database， you have created the ORDERS table as an index/x7forganized table （IOT）. To facilitate faster querying， you have created a mapping table and a bitmap index on the ORDER_FILLED column. You observe that the query performance degrades when users perform a large volume of transactions. While investigating the reason， you find that the mapping table segment is fragmented， leading to poor performance. Which option would you use to defragment the mapping table without affecting the original table data？（）A、export and import the mapping tableB、drop and recreate the mapping tableC、truncate the mapping table and reinsert the valuesD、use the ALTER TABLE .. REBUILD command to defragment the mapping table

Which option is NOT a disadvantage of using block media recovery？（）A、 Block Media Recovery must be used with RMAN.B、 You must perform complete recovery of individual blocks.C、 You must have a full RMAN backup， not an incremental backup.D、 You must use the DBVERIFY utility before using the Block Media Recovery feature.
