CCNA Chapter #3

1. The following line of code is preset in the routing table :
0 10.16.1.0/27 {110/129 via 192.168.1.5,00:00:05,Serial 0/0/1
what does the number 129 indicate in this output ?

The cost for this link has a value of 129

The clock rate on this serial interface is set to 129000

The next hop router is 129 hops away from this router

This route has been updated 129 times

2. What is the purpose of the routing protocol ?

It is used to build and maintain ARP tables

It provides a method for segmenting and reassembling data packets

It allows an administrator to devise an addressing scheme for the network

It allows a router to share information about known networks with other routers

It provides a procedure for encoding and decoding data into bits for packet forwarding

3. The following line of code is displayed in a routing table:
R 209.165.201.0/24{120/2 via 192.168.252.2,00:00:16 S 0/0/0

The packet destined for host 192.168.252.2 will be forwarded out the interface connected to network 209.165.201.0/24

This route was manually configured using the ip route command

192.168.252.2 is an interface on the router that produced this outpus

4. Refer to the exhibiy .which statement correctly describes how R1 will determine the best path of R2?

R1 will install an EIGRP route and a RIP route in its oruing table and load balance between them.

5. Why is fast convergence desirable in networks that use dynamic routing protocols ?

Routers will not allow packets to be forwarded until the network has converged

Hosts are unable to access their gateway until the network has converged

Routers may make incorrect forwarding decisions until the network has converged

Routers will not allow configuration changes to be mad until the network has converged

6. A router learns two paths will equal metrics to a destination network via RIP routing protocol.How will the router handle packets to the destination network?

The router will install the first route it learned into the routing table

The router will install both routes in the routing table and load balance between the two.

The router will put the first route in the routing table, and denote the second route as a backup route

The router will pick the path with the higher bandwidth and will place it in the routing table

7. Which command would the network administrator issue to determine if load balancing is in effect router?

Show ip protocols

Show ip route

Show interface brief

Show ip interface

8. What will be the result of the following commands?
ORL(config)#interface fastethernet 0/0
ORL(config_if)#ip address 172.16.3.1 255.255.255.0
ORL(config-if)#no shutdown

The 172.16.3.0 network will be routed by any dynamic routing protocol automatically

A routing table entry is made to the 172.16.3.0 network with a code of C

A static route is required to route traffic to the 172.16.3.0 network

The commands will be saved to the startup-configuration automatically

9. When multiple routing protocols have a route to the same destination network what determines which routeis installed in the routing table ?

Best metric

Lowest hop count

Greatest available bandwidth

Lowest administrative distance

Lowest cost

10. Refer to the exhibit. router 1 and router 2 are running EIGRP.All interfaces are operational and packets can be forwarded between all networks.What information will be found in the routing table for Router 1 ?

Router 1 will have 6 directly connected networks

The administrative distance of the route of network 172.16.0.0 will be 90

The metric for routes to 172.16.00 will be 1

The interface that is used to forward packets to 172.16.00 will always be S0/1 interface

11. Refer to the exhibit.If RIP is the routing protocol ,what is the value of the metric from router A to network ,192.168.5.0/24

12. An engineer creates a static route by entering the Router(config) # ip route 10.0.0.0 255.255.255.0 192.168.1.2 command .what can be concluded about this route

The administrative distance of this route is 1

192.168.1.2 is the address of an interface on this router.

This route will display as a directly connected network in the routing table

Packets with a destination IP address of 192.168.1.2 will be forwarded to the 10.0.0.0/25 network first.

13. Which two statements are true regarding classless routing protocols ? choose two

Sends subnet mask information in routing updates

Sends complete routing table update to all neighbors

Is supported by RIP version 1

Allows for use of both 192.168.1.0/30 and 192.168.1.16/28 subnets in the same topology

Reduces the amount of address space available in an organization

Submit

14. Which of the following best describes the operation of distnance vector routing protocols ?

They use hop count as their only metric

They only send out updates when a new network is added

They send their routing tables to directly connected neighbors

They flood the entire network with routing updates

15. Which two statements are true regarding metrcs (choose two )

RIP uses bandwidth as a metric

OSPF uses delay as a metric

EIGRP uses bandwidth as a metric

OSPF uses cost based on bandwidth as a metric

RIP uses delay as a metrci

Submit

16. Which two conditions would create a setting where the use of a distance vector routing protocol would be efficient ?(choose two.)

The network requires a special hierarchical design

Fast convergence of the network is crucial

The network is using a hub and spoke topology

There are than 15 hops between the most distant routers

Submit

17. Which of the following conditions must be met in order for a network to have converged ?
