A

Default Route

62
Q

This is defined as a network that is not listed in the router’s routing table.

A

Non routable

63

This is a network layer protocol that exchanges information packets with other internetwork routers in order to build and maintain a routing table

A

Routing protocol

64
Q

This is the most common routing metric

A

Path length

65
Q

This is another routing metric but refers to the dependability of each network link

A

Reliability

66
Q

This refers to the length of time required to move a packet from source to destination through the internetwork.

A

Delay

67
Q

This refers to the available traffic capacity of a link

A

Bandwidth

68
Q

This refers to the degree to which a network resource, such as a router,is busy

A

69
Q

These initialize and maintain routing tables.

A

Algorithms

70
Q

This type of algorithm supports multiple paths to the same destination by load balancing or load sharing

A

Multi path algorithms

71
Q

In this algorithm the routers are peers of all the other.

Sometimes considered the classful routing

A

Flat algorithms

72
Q

This routing structure is called classless routing and supports VLSM

Q

Works with interior gateway protocols like RIP,IGRP,EIGRP,OSPF and IS-IS

Works only within a routing domain

A

Intramural-Domain algorithm

75
Q

This algorithm is used between autonomous systems and is used with exterior gateway protocols

A

Inter-domain algorithms

76
Q

This algorithm calls for each router to send all of its routing table, but only to neighbors by way of Limited broadcast -255.2.55.255.255 that routers are designed not to pass

A

Distance vector

77
Q

Is distance vector classful or classless ?

A

Classful

78
Q

A

Topological database

88
Q

What is called when two neighbor routers are synchronized?

A

Adjacent

89
Q

This router is responsible for generating LSAs for the entire area so only one router is responsible for sending multicast updates.
