| 13: | What are the advantages and disadvantages of Mobile IP over IPSec? |
| 14: | Registration Revocation allows for which of the following? Timely release of Mobile IP resources Early adoption of domain policy changes with regard to services offered/required of a Mobile IP binding Timely notification to a Mobile Nodes that it is no longer receiving mobility services, thereby significantly shortening any black-hole periods to facilitate a more robust recovery. Accurate Mobile IP and resource accounting All of the above
