EIGRP uses the same metric as IGRP multiplied by ____.

A) 32
B) 64
C) 128
D) 256

Question 13

Classful routing protocols can be used in networks with either discontiguous subnets or networks using variable length subnet masks (VLSM).

Question 14

____ allow EIGRP to discover neighbors and keep track of their status.

A) Reliable Transport Protocol
B) Protocol Dependent Modules
C) Neighbor discovery and maintenance
D) Diffusing Update Algorithm (DUAL)

Question 17

The ____ command overrides RIPv2's default behavior of summarizing to major network boundaries.

A) no default
B) no default summary
C) auto-summary off
D) no auto-summary

In general, ____ routing protocols send periodic updates of the entire routing table to their directly connected neighbors.

A) link-state
B) distance-vector
C) exterior gateway
D) interior gateway

Question 19

EIGRP uses nonperiodic, partial, and bounded routing table updates.

Question 20

OSPF is ideally suited for large networks because it can use a concept known as areas to bound link-state advertisements.

Describe the Routing Information Protocol version 2.

Question 22

Describe the Enhanced Interior Gateway Routing Protocol (EIGRP).

Question 23

What are the major components of EIGRP?

Question 24

Question 30

____________________ routing protocols summarize networks to their major network boundaries (Class A, B, or C) and do not carry subnet mask information in their routing table updates.

Question 31

The ___________________________________ is the heart and soul of EIGRP, and is the reason that EIGRP can quickly recover from a link outage and route around network problems.

Question 32

___________________________________ allow EIGRP to carry multiple routed protocols within their own native packet formats.
