Network+ Chapter 10

Question 1

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

Answer 1

administrative distance (AD)

Question 2

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

Answer 2

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

Question 3

What is the default administrative distance of static route?

ch 10 pg 301

Answer 3

1

Question 4

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

Answer 4

90

Question 5

What is the default administrative distance of RIP?

ch 10 pg 302

Answer 5

120

Question 6

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

Answer 6

170

Question 7

Using link state protocols, also called what?

ch 10 pg 302

Answer 7

shortest path first protocols,

Question 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

Answer 8

hybrid protocol

Question 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

Answer 9

round-robin load balancing.

Question 10

What are 4 differences between RIPv1 and RIPv2.

Ch 10 og 306

Answer 10

RIPv1  
Classful   
Broadcast Based
No Support for VLSM
No Authentication

RIPv2
Classless
Uses multicast 224.0.0.9
Supports VLSM
Allows for MDS Authentication

Question 11

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

Answer 11

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

Question 12

What is a discontigous network?

Answer 12

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

Question 13

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

Answer 13

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

Question 14

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

Answer 14

Feasible Successor (Backup Routes)

Question 15

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

Answer 15

Open Shortest Path First (OSPF)

Question 16

which algorithm is used by OSPF? pg 314

Answer 16

Dijkstra algorithm.

Question 17

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

Answer 17

IS-IS

Question 18

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

Answer 18

first hop

Question 19

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

Answer 19

Virtual Router Redundancy Protocol (VRRP).

Question 20

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

Answer 20

Hello Timer

Question 21

allows a group of routers to form a single virtual router.

p. 324

Answer 21

Virtual Router Redundancy Protocol (VRRP)
