# Final Exam Clarifications

**Question:** * I was just wondering for the link state diagram, can we assume that we start from A? It is specified for the distance vector that we start from A, but not for the link state problem. *

**Answer:** Yes, assume that you start with node A for both the link state and distance vector portions of the problem.

**Question:** *Regarding question 6, can we explain any of the strategies that have been described in the book such as token ring LAN or any other taking turns protocols? *

**Answer:** For question 6 you should explore an alternative to exponential backoff, not to Ethernet. If you simply summarize material
from the book you will receive fewer points.
