flashback table employees to scn 123456;
The employees table has triggers associated with it. Which of the following statements is true regarding

A. All the triggers are disabled.
B. All the triggers are enabled by default.
C. Enabled triggers remain enabled and disabled triggers remain disabled.
D. Triggers are deleted when a Flashback Table operation is performed.
Answer: A

By default, the database disables triggers on the affected table before performing a FLASHBACK TABLE operation. After the operation, the database returns the triggers to the state they were in before the operation (enabled or disabled). To keep triggers enabled during the flashback of the table, add an ENABLE TRIGGERS clause to theFLASHBACK TABLE statement
