Flashcards in Network+ Chapter 10 Deck (21):
1

is used to rate the trustworthiness of routing information received on one router from its neighboring router. pg 300

administrative distance (AD)

2

Disabling all the routing protocols except this _______protocol improved the network at least 30% pg 301

EGIRP (this would only work on an all-Cisco router network)

3

What is the default administrative distance of static route?
ch 10 pg 301

1

4

What is the default administrative distance of Internal EIGRP? ch 10 pg 302

90

5

What is the default administrative distance of RIP?
ch 10 pg 302

120

6

What is the default administrative distance of External EIGRP?
ch 10 pg 302

170

7

Using link state protocols, also called what?
ch 10 pg 302

shortest path first protocols,

8

This protocol uses aspects of both distance vector and link state, and formerly, EIGRP was the only one you needed to understand to meet the Network + objectives.Ch 10 pg 303

hybrid protocol

9

If a router finds more than one link with the same hop count to the same remote network, it will automatically perform what's known as what? Ch 10 pg 303

round-robin load balancing.

10

What are 4 differences between RIPv1 and RIPv2.

Ch 10 og 306

RIPv1
Classful
Broadcast Based
No Support for VLSM
No Authentication

RIPv2
Classless
Uses multicast 224.0.0.9
Supports VLSM
Allows for MDS Authentication

11

By using a VLSM design, your network will run faster and you can save a lot of IP addresses. Ch 10 pg 308

False-By using a VLSM design, you do not necessarily make your network run better, but you can save a lot of IP addresses.

12

What is a discontigous network?

Its a network that has two or more subnetwork of classful network connected together by different classful networks

13

What are 3 reasons to create a OSPF in a Hierarchical design?

To decrease routing overhead
To Speed Up Convergence
To confine network instability to single areas of the network.

14

is a path whose reported distance is less than the feasible (best) distance, and it is considered a backup
route. pg 311

Feasible Successor (Backup Routes)

15

is an open-standard routing protocol that's been implemented by a wide variety of network vendors, including Cisco. pg 313

Open Shortest Path First (OSPF)

16

which algorithm is used by OSPF? pg 314

Dijkstra algorithm.

17

is a link state routing protocol, meaning it operates by reliably flooding topology information throughout a network of routers.
(p. 316).

IS-IS

18

is a reference to the default router being the first router, or _________ through which a packet must pass.
(p. 317).

first hop

19

This also provides a redundant— but again, not load-balanced— gateway for hosts on a local subnet.
(p. 319).

Virtual Router Redundancy Protocol (VRRP).

20

The_______ timer is the defined interval during which each of the routers send out ______ messages.
(p. 322).

Hello Timer

21

allows a group of routers to form a single virtual router.
(p. 324).
