You are working in an online transaction processing （OLTP） environment. You used the FLASHBACK TABLE command to flash back the CUSTOMERS table. Before executing the FLASHBACK TABLE command， the System Change Number （SCN） was 663571. After flashing back the CUSTOMERS table， you realize that the table is not in the correct state and the resultant changes are not what you had desired. So， you need to reverse the effects of the FLASHBACK TABLE command while ensuring that：
a） No other user data in the database is affected.
b） The operation takes the minimum possible time.
Which option would you choose？（）
A. Use ROLLBACK command with SCN 663571.
B. Perform Flashback Transaction Query with SCN 663571.
C. Execute the FLASHBACK DATABASE statement to retrieve the CUSTOMERS table as it was at SCN 663571.
D. Execute another FLASHBACK TABLE statement to retrieve the CUSTOMERS table as it was at SCN 663571.
A. Backup of offline tablespaces.
B. Backup of read-only tablespaces.
C. Backup of system-critical tablespaces.
D. Backup of online， locally managed tablespaces.

One of the tablespaces is readonly in your database. The loss of all control files forced you to recreate the control file. Which operation do you need to perform after recreating the control file and opening the database？（）
The current time is 12：00 noon. You want to recover the USERS tablespace from a failure that occurred at 11：50 a.m. You discover that the only member of an unarchived redo log group containing information from 11：40 a.m. onwards is corrupt.
