View the Exhibit and examine the disk groups created at the time of migrating the database storage to Automatic Storage Management （ASM）. 
Why does the FRA disk group initially have more free space even though both DATA and FRA disk groups are provided with the same size？（）

In your production database， users report that they are unable to generate reports on an important table because it does not contain any data. While investigating the reason， you realize that another user executed the TRUNCATE TABLE command， which accidentally caused the data to be lost. Now you want to recover the lost data of the table without affecting objects in other schemas. 
Which method must you use to recover the lost data？（）
