B. By implementing Fine-Grained Auditing (FGA)
C. By granting a secure application role to the users
D. By implementing the Database Resource Manager plan
Q50. Your database is functional with a peak load for the last one hour. You want to preserve the performance statistics collected during this period to be used for comparison when you analyze the performance of the database in the future.
