Answer

Origin

Question 6

What is the primary purpose of the split horizon rule in dynamic routing protocols?

Accepted Answer

Prevent routing loops

Answer

Optimize routing paths

Answer

Enhance network security

Answer

Reduce network overhead

Question 7

What is the key distinction between distance-vector and link-state routing protocols?

Accepted Answer

Distance-vector protocols use hop count, while link-state protocols use link cost.

Answer

Distance-vector protocols are simpler, while link-state protocols are more complex.

Answer

Distance-vector protocols converge faster, while link-state protocols converge slower.

Answer

Distance-vector protocols are used in large networks, while link-state protocols are used in small networks.

Suppress routing advertisements for specific destinations.

Answer

Propagate routing advertisements for specific destinations.

Answer

Block routing advertisements from specific neighbors.
