CCNA Implementation SIM
This topology contains 3 routers and 1 switch. Complete the topology.
Drag the appropriate device icons to the labeled Device
Drag the appropriate connections to the locations labeled Connections.
Drag the appropriate IP addresses to the locations labeled IP address
(Hint: use the given host addresses and Main router information)
To remove a device or connection, drag it away from the topology.
Use information gathered from the Main router to complete the configuration of any additional routers. No passwords are required to access the Main router. The config terminal command has been disabled for the HQ router. The router does not require any configuration.
Configure each additional router with the following:
Configure the interfaces with the correct IP address and enable the interfaces.
Set the password to allow console access to consolepw
Set the password to allow telnet access to telnetpw
Set the password to allow privilege mode access to privpw
Note: Because routes are not being added to the configurations, you will not be able to ping through the internetwork.
All devices have cable autosensing capabilities disabled.
All hosts are PC’s
Answer and explanation
Note: You can download this sim to practice here: http://www.9tut.com/download/9tut.com_CCNA_Implementation_question.zip
Specify appropriate devices and drag them on the “Device” boxes
For the device at the bottom-right box, we notice that it has 2 interfaces Fa0/2 and Fa0/4; moreover the link connects the PC on the right with the device on the bottom-right is a straight-through link -> it is a switch
The question stated that this topology contains 3 routers and 1 switch -> two other devices are routers
Place them on appropriate locations as following:
(Host D and host E will be automatically added after placing two routers. Click on them to access neighboring routers)
Specify appropriate connections between these devices:
+ The router on the left is connected with the Main router through FastEthernet interfaces: use a crossover cable
+ The router on the right is connected with the Main router through Serial interfaces: use a serial cable
+ The router on the right and the Switch: use a straight-through cable
+ The router on the left and the computer: use a crossover cable
(To remember which type of cable you should use, follow these tips:
- To connect two serial interfaces of 2 routers we use serial cable
– To specify when we use crossover cable or straight-through cable, we should remember:
Group 1: Router, Host, Server
Group 2: Hub, Switch
One device in group 1 + One device in group 2: use straight-through cable
Two devices in the same group: use crossover cable
For example: we use straight-through cable to connect switch to router, switch to host, hub to host, hub to server… and we use crossover cable to connect switch to switch, switch to hub, router to router, host to host… )
Assign appropriate IP addresses for interfaces:
From Main router, use show running-config command:
(Notice that you may see different IP addresses in the real CCNA exam, the ones shown above are just used for demonstration)
From the output we learned that the ip address of Fa0/0 interface of the Main router is 192.168.152.177/28. This address belongs to a subnetwork which has:
Increment: 16 (/28 = 255.255.255.240 or 1111 1111.1111 1111.1111 1111.1111 0000)
Network address: 192.168.152.176 (because 176 = 16 * 11 and 176 < 177)
Broadcast address: 192.168.152.191 (because 191 = 176 + 16 – 1)
And we can pick up an ip address from the list that belongs to this subnetwork: 192.168.152.190 and assign it to the Fa0/0 interface the router on the left
Use the same method for interface Serial0/0 with an ip address of 192.168.152.161
Increment: 16
Network address: 192.168.152.160 (because 160 = 16 * 10 and 160 < 161)
Broadcast address: 192.168.152.175 (because 176 = 160 + 16 – 1)
-> and we choose 192.168.152.174 for Serial0/0 interface of the router on the right
Interface Fa0/1 of the router on the left
IP (of the computer on the left) : 192.168.152.129/28
Increment: 16
Network address: 192.168.152.128 (because 128 = 16 * 8 and 128 < 129)
Broadcast address: 192.168.152.143 (because 143 = 128 + 16 – 1)
-> we choose 192.168.152.142 from the list
Interface Fa0/0 of the router on the right
IP (of the computer on the left) : 192.168.152.225/28
Increment: 16
Network address: 192.168.152.224 (because 224 = 16 * 14 and 224 < 225)
Broadcast address: 192.168.152.239 (because 239 = 224 + 16 – 1)
-> we choose 192.168.152.238 from the list
Let’s have a look at the picture below to summarize
Configure two routers on the left and right with these commands:
Router1 = router on the left
Assign appropriate IP addresses to Fa0/0 & Fa0/1 interfaces:
Router1>enable
Router1#configure terminal
Router1(config)#interface fa0/0
Router1(config-if)#ip address 192.168.152.190 255.255.255.240
Router1(config-if)#no shutdown
Router1(config-if)#interface fa0/1
Router1(config-if)#ip address 192.168.152.142 255.255.255.240
Router1(config-if)#no shutdown
Set passwords (configure on two routers)
+ Console password:
Router1(config-if)#exit
Router1(config)#line console 0
Router1(config-line)#password consolepw
Router1(config-line)#login
Router1(config-line)#exit
+ Telnet password:
Router1(config)#line vty 0 4
Router1(config-line)#password telnetpw
Router1(config-line)#login
Router1(config-line)#exit
+ Privilege mode password:
Router1(config)#enable password privpw
Save the configuration:
Router1(config)#exit
Router1#copy running-config startup-config
Configure IP addresses of Router2 (router on the right)
Router2>enable
Router2#configure terminal
Router2(config)#interface fa0/0
Router2(config-if)#ip address 192.168.152.238 255.255.255.240
Router2(config-if)#no shutdown
Router2(config-if)#interface serial0/0
Router2(config-if)#ip address 192.168.152.174 255.255.255.240
Router2(config-if)#no shutdown
and set console, telnet and privilege mode passwords for Router2 as we did for Router1, remember to save the configuration when you finished
Other lab-sims on this site:
Testtaker tim,
Using the command “router(config)#enable password XXXX” does not encrypt clear text passwords. This only sets a password for enabling the rtr to the privilege exec mode. To encrypt clear text passwords, you have to issue the command “router(config)# service password-encryption”. This command will encrypt clear text passwords on the router.
Wow, this is in every respect what I nedeed to know.
Magnificent goods from you, man. I’ve understand your stuff previous to and you are just extremely fantastic. the life of kendal shaw http://www.tvxqinsh.com/forum.php?mod=viewthread&tid=134753
How come I’m receiving a error every time I try to open these files with Packet Tracer? I get filename.pkt is not a valid Packet Tracer file.
Anyone see this question on a test recently?
Pls how do i get reg code for vce download, it’s running in trial version
On the left of the main router, why have we used a router? As it is a Fast Ethernet connectivity, I was under the impression to use a Switch and have Host A connected via the straight-through cable.
Can someone please explain the logic?
Thanks in advance.
@Zaya
the left device has fastethernet port fa0/0 and thus it is a router because switch has a range from 1-24 and not from 0 -23.
I would like to say thanx to 9tut, I have Just passed CCENT yesterday and this Simulation was there. Know the CDP command in and out… All in all thank you guys you doing a great Job!
To sit for the ccna exam next month and i real need dumps pliz anyone with,send to email:olesimbe@yahoo.com. Thanks a lot!!.
For this one, would you choose a serial dce connection or dte connection?
i am gay
I completed ccna with 986/1000 .I prepard exam only with the help of pass4sure v10 653 questions .Which was realy helpful .
http://6c11e1d9.qqc.co refer this site
I pass with 9xx…thanks 9tut
3 sim: this one , ACL and Frame-relay
Only 3 new questions (I didn’t see them before)
Do we really need to apply any IP’s for the devices on the real exam or is it drag and drop sim?
If ‘show cdp neighbors’ was available, I’d use that instead, as routers CAN have a slot with 4 fast ethernet ports. You shouldn’t assume that fa0/4 = switch.
This will give the neighboring device’s capabilities (e.g. router), allowing for the bottom right device to be determined by elimination. It also reflects what is being asked in the question: use the main router to determine the other devices.
To find IP addresses, use ‘sh ip int brief’, rather than ‘show run’.
Why only router1 and router 2 configure password?
I don’t find that requirement at question.
will this sim come out for CCNA 640 – 802 ?
@Elias, you need to apply IP addresses to 2 additional routers (on the left and right), you need to access the middle one just to see what IP addresses have been assigned to its interfaces,
@anonymous, why not :D this is how cisco decided to go about that question, you won’t be able to make any changes on the central router anyway, read that
“The config terminal command has been disabled for the HQ router. The router does not require any configuration.”
do you not need clock rate on R2 for serial 0/0?
As per omar sim: this one , ACL and Frame-relay, is it true?
Please advice me 9tut
What i am going to do, if i want to take the CCNa 640-802? thus it affect the new cisco accnt on cisco.netacad.com that your going to take, because i take the cisco subject last 3 years ago, and when i see the new cisco site its kinda different, or it still te same, or is it matter to me whether i book for CCNA 640-802? Im kinda confused because of the CCNa 200-… Ssomething, thanks for your anwser, i really appreciate it…
@chanaka: The sims for the CCNA 640-802 exam are EIGRP, VTP, ACL 2. This sim will not appear in your exam.
@Kyu: In fact the new CCNA 200-120 is 80% similar to the 640-802 exam but with smaller pool of questions. The CCNA 640-802 will be retired on Sep-30-2013. If now you have not had prepared well then maybe you should take some time learning and take the new CCNA 200-120.
Are any of these sims on the exam:
Other lab-sims on this site:

if you use a DTE serial cable ping 192.168.152.174 from main router is not working. With DCE ping works so I believe DCE is the right choice.
Can anyone advise where can I find Frame Relay Sim? It is not listed on the main page.
fiz meu exame dia 06/09 e este lab caiu em minha prova, tive a pontuação de 801 e infelizmente não passei rsrsrsr,

Conforme havia escrito acima, fiz a prova hoje (24/09) me enganei escrevendo que faria dia 27.
passei com 920 pontos (92% de acerto) e caiu esse lab para fazer, porém os endereços de IP totalmente diferente.
O outro LAB foi de NAT/PAT que caiu.
abraços e boa sorte a todos.
