N10-005 Question #497: Real Exam Question with Answer & Explanation

The correct answer is B: RIP. RIP (Routing Information Protocol) uses hop count as its sole routing metric, with a maximum of 15 hops (16 is considered unreachable). BGP (Border Gateway Protocol) uses path attributes such as AS-path length and policy. OSPF (Open Shortest Path First) uses cost, which is based

Question

Which of the following dynamic routing protocols selects routing paths based upon hop count?

Options

ABGP
BRIP
COSPF
DIGRP

Explanation

RIP (Routing Information Protocol) uses hop count as its sole routing metric, with a maximum of 15 hops (16 is considered unreachable). BGP (Border Gateway Protocol) uses path attributes such as AS-path length and policy. OSPF (Open Shortest Path First) uses cost, which is based on link bandwidth. IGRP (Interior Gateway Routing Protocol) uses a composite metric incorporating bandwidth, delay, reliability, and load. RIP's simplicity makes it easy to configure but unsuitable for large or complex networks due to its limited hop count and slow convergence.
