Q

True / False: EIGRP must receive a response when querying other routers after a route goes down?

A

Q

What is indicated when an EIGRP route is in the passive state?

A

The route is viable and can be used to forward traffic.

17
Q

True / False: EIGRP packets are use reliable delivery?

A

False

19
Q

The Finite State Machine is?

A

An abstract machine that defines states, events that cause states & what events result from states

21
Q

True / False: EIGRP supports authenticated routing updates much like OSPF and RIP?

A

True

21
Q

EIGRP does not have a Dead-Timer, instead they have?

A

Hold-Timer

22
Q

In EIGRP, what describes how an algorithm will react to events?

A

The Finite State Machine

22
Q

In EIGRP, ff DUAL is recalculating/searching routes are?

A

Active

24
Q

What is an EIGRP Split Horizon?

A

Routes learned on an interface are not advertised out that interface are not advertised out that interface

27
Q

The EIGRP packet header contains what number?

A

The AS number

27
Q

What is the purpose of using protocol-dependent modules in EIGRP?

A

To accommodate routing of different network layer protocols

28
Q

EIGRP Hello Packets multicast to what IPv6 address?

A

FF02::A

29
Q

EIGRP is what type of Routing Protocol (Link-State | Distance Vector)

A

Distance Vector

30
Q

True / False: Some IOS versions allow you to use netmasks rather than wildcard masks with the EIGRP network command?

A

True.

31
Q

Acknowledgement Packets use unreliable or reliable delivery?

A

Reliable

33
Q

The Administrative Distance for an EIGRP Internal route is?

A

90

34
Q

What command enables EIGRP on a router?

A

router eigrp

35
Q

In 1992 Cisco took redeveloped IGRP and changed it to what?

A

Enhanced IGRP

36
Q

EIGRP uses what to route different protocols?

A

Protocol Dependent Modules

37
Q

What argument can be added to the show ip eigrp topology to show routes that are not feasible?

A

all-links

39
Q

The default Hello-Interval for multiaccess networks is?

A

Every 5 seconds

40
Q

RTP involves both Reliable and Unreliable delivery, what is the major difference between the two?

A

Reliable delivery requires ACK from destination

41
Q

The default Hello-Interval for NMBA networks is?

A

Every 60 seconds

41
Q

Where are EIGRP successor routes stored?

A

In the routing table and the topology table
