Question

What Layer 3 technology is employed by distance-vector routing protocols in which a router knows which of its interfaces a routing update and will not retransmit, or advertise, that same update on the same interface?

A) split horizon
B) round robin
C) reverse path check
D) spanning tree protocol

Answer 1

So option A is correct which is split technology

Step-by-step explanation:

The technology which is employed by distance vector routing protocols in which a router knows which of its interfaces a routing update and will not re-transmit , or advertise,that same update on the interface is split technology. In slit technology there will no loops of routing. The data received from one protocol will not be advertised back to same protocol.

So option A is correct which is split technology
