Which of these potential issues is eliminated by the use of split horizon?

A.
asymmetric routing throughout the network

B.
packet forwarding loops

C.
joined horizons

D.
Cisco Express Forwarding load-balancing inconsistency

Explanation:
Distance-vector routing protocols employ the split horizon rule which prohibits a router from
advertising a route back out the interface from which it was learned. Split horizon is one of the
methods used to prevent routing loops due to the slow convergence times of distance-vector
routing protocols.
