What are the two methods used to prevent loops in a distance vector routing protocol?
A) Split horizon and hold-down timer
B) Split horizon and poison reverse
C) Poison reverse and hop count
D) Split horizon and hop count
B
Explanation: Distance vector routing protocols typically use split horizon or poison reverse for preventing routing loops. The split-horizon method prevents a route learned on one interface from being advertised back out of that same interface, and the poison-reverse method causes a route received on one interface to be advertised back out of that same interface with a metric considered to be infinite or unreachable.
