AnswerD.
3 and 4
Answer: Option C
Solution
Answer: Option C
Solution:
RIPv2 uses the same timers and loop-avoidance schemes as RIPv1. Split horizon is used to stop an update from being sent out the same interface it was received on. Holddown timers allow time for a network to become stable in the case of a flapping link.
