Hey Brenda,
Ok, you've got Form-based authentication discussed on page 647, and you've got data confidentiality / integrity discussed on page 652. If you compare them, you'll see that they work independently of one another
To get them to work together, check out pages 653-655!
Good luck on the exam, let us know how you do! And... if it seems that you need more time to study, postpone the exam!
