You are working in an online transaction processing (OLTP) environment. You use 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.
Now, you need to reverse the effects of the FLASHBACK TABLE command.
Which is the fastest and the most efficient option to reverse the effects of the FLASHBACK
TABLE command?
A.
Restore the backup control file and open the database with RESETLOGS option.
B.
Perform point-in-time recovery because flashback cannot be performed again on this
table
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
