QUESTION 2Lab SIM - RIP v2

A.B.C.D.


Explanation/Reference:(1) Name the router:Router>enableRouter#config terminalRouter(config)#hostname Orlando

(2) Enable-secret password (cisco10):

Orlando(config)#enable secret cisco10

(3) Set the console password toRouterPass:Orlando(config)#line console 0Orlando(config-line)#password RouterPassOrlando(config-line)#loginOrlando(config-line)#exit

(4) Set the Telnet password toscan90:Orlando(config)#line vty 0 4Orlando(config-line)#password scan90Orlando(config-line)#loginOrlando(config-line)#exit

(5) Configure Ethernet interface (on the right) of router Orlando:The subnet mask of the Ethernet network 209.165.201.0 is 27. From this subnet mask, we can find out theincrement by converting it into binary form, that is /27 = 1111 1111.1111 1111.1111 1111.1110 0000. Pay moreattention to the last bit 1 because it tells us the increment, using the formula:Increment = 2place of the last bit 1 (starts counting from 0,from right to left), in this case increment = 25= 32.Therefore:Increment: 32Network address: 209.165.201.0Broadcast address: 209.165.201.31 (because 209.165.201.32 is the second subnetwork, so the previous IP –209.165.201.31 – is the broadcast address of the first subnet).-> The second assignable host address of this subnetwork is209.165.201.2/27Assign the second assignable host address to Fa0/0 interface of Orlando router:Orlando(config)#interface Fa0/0Orlando(config-if)#ip address 209.165.201.2 255.255.255.224Orlando(config-if)#no shutdownOrlando(config-if)#exit

(6)Configure Serial interface (on the left) of rout er Orlando:Using the same method to find out the increment of the Serial network:Serial network192.0.2.128/28:Increment: 16 (/28 = 1111 1111.1111 1111.1111 1111.11110000)Network address: 192.0.2.128 (because 8 * 16 = 128 so 192.0.2.128 is also the network address of thissubnet)Broadcast address: 192.0.2.143-> The last assignable host address in this subnet is192.0.2.142/28.Assign the last assignable host address to S0/0/0 interface of Orlando router:Orlando(config)#interface S0/0/0(or use interface S0/0 if not successful)Orlando(config-if)#ip address 192.0.2.142 255.255.255.240Orlando(config-if)#no shutdownOrlando(config-if)#exit

(7) Configure RIP v2 routing protocol:Orlando(config)#router ripOrlando(config-router)#version 2Orlando(config-router)#network 209.165.201.0Orlando(config-router)#network 192.0.2.128Orlando(config-router)#end

(8)Save the configuration:Orlando#copy running-config startup-configFinally, you should use theping command to verify all are working properly!

Answer: 192.168.200.31Explanation:User the " show ip interface brief" command

User the " show interface fa0/1" command

QUESTION 42what is the bandwidth on the WAN interface of Route r?

A. 16 Kbit/secB. 32 Kbit/secC. 64 Kbit/secD. 128 Kbit/secE. 512 Kbit/secF. 1544 Kbit/sec



Answer: 512 Kbit/secExplanation:Use the " show interfaces serial 0/0" command

QUESTION 43what interface router 1 have not had any configurat ion applicd? (choose two)

A. Ethernet B. Fastethernet 0/0C. Fastethernet 0/1D. serial 0E. serial 0/0F. serial 0/1

Correct Answer: BFSection: GExplanation


Answer: FastEthernet0/0 and Serial 0/1Explanation:User the " show ip interface brief" commandNotice that Router1 does not have Ethernet 0 and Se rial 0 interfaces. FastEthernet 0/1and Serial 0/0 were configured with their IP addres ses therefore only FastEthernet 0/0and Serial0/1 have not had any configurations appli ed.

QUESTION 44including the address on the router1 interface how many hosts can have ip addresseson the LAN to whitch router1 is connected?

A. 6B. 14C. 62D. 126



Answer: 14Explanation:The mask address of interface Fa0/1 of Router1 is / 28, which has four 0 bits (11111111.1111 1111.1111 1111.11110000). Therefore there are 24– 2 = 14 assignable IPaddresses for hosts on the LAN

QUESTION 45the hosts in the lan are not able to connect to the internet . which commands willcorrect this issue?

A.B.C. Router1(conf)# interface s0/0

Router1(conf-if)# no shutdownD.



Answer:Router1(conf)# interface s0/0Router1(conf-if)# no shutdown

Explanation:User the " show ip interface brief" command

From the output, we learn that the status of Serial 0/0 interface which connects to ISProuter is currently "administratively down". This s tatus indicates this interface isshutting down so we need to turn it on.
