Implementation SIM 2
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:
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 in the ICND 1 Exam:
ICND 1 – Show Configuration Sim
Frame Relay Sim – Hotspot (on 9tut.com)
Other lab-sims might appear in the real ICND 1 exam, read and understand them if you have enough time!
Passed today (938 points) had this question as question number 10 (i think) Could ping, from Router1 to HQ and vice versa but couldn’t ping the serial interface of Router2.
Couldn’t even ping the ip address of s0/0 of router2 from the console of router2.
BTW: after you set the enable password, it may that when you want to config the router it doesn’t accept the password, whatever you enter, the password: prompt keeps coming back. The trick is to remove the router from the topology (just drag it back to the bottom left) and than re-add it. It keeps your made configuration, but now accepts the password :~
I know it says that routing isn’t configured (show ip route is disabled in the sim, so is show ip arp)
Did I made a configuration error by not being able to test the serial connection with a ping?
Found out the wording of this in the exam has a (.) at the end of the password configuration instructions and the rest do not.
I also found out if you follow the directions to a tee and include the . at the end of the password you will get it wrong.
after many phone calls with Cisco and pearson vue they correct my test and gave me the points needed to pass.
Everyone should note this when they take the test. don’t be literal (like a computer test should be) and follow the instructions to the dot lol (pun fully intended)
Dear All,
1. Can anybody provide me the details of Drag n Drop question below:
Phising
Trojan
Spyware
Virus
2. Can you also provide details on the testlets questions about the following:
A) 8 PCs connected to a hub
B) Multiple choice questions about security concerns based on show run output of router and switch.
Thanks in advance
did the same thing as pegege and added the dot at the end of the password. the password and the dot were in bold text and so I followed instructions.
no other sentences in the instructions had a full stop either.
going to take it up with cisco and see what happens.
passed anyway but feel cheated.
this is the second time i had writen the exam and this question came up both times.
also know what happens when there are 2 switches connected. one switch is connected to a hub with 8 pcs connected and the other switch has 8 pc’s directly connected. know the switching processes well!!ie. add a computer, remove pc, switch mac tables with hub interaction.
Studied and did lots of dumps but this exam was still hard. maybe 20% from dumps first exam and 40% second time.
Know your stuff!!
Thanks 9tut.net and ciscobibles.com
I passed the exam today.
some new questions in the exam.

Thanks
what Passing score of exam 640-822 how many question and simualtaion are are come in exam
thanks
Helpful blog, bookmarked the website with hopes to read more!
Really nice information, thanks!
can some one send me the latest dumps for ICND1 and ICND2. Thanks, v0052003@yahoo.com
I believe Router 2 on the right needs to have a clock rate set of 6400 for the Serial Port, I believe this is missing?. Perhaps its already set?
Also not sure why Router 1 on the left has to be a Router, why can’t it be a switch?, probably missing something obvious but maybe someone can put me straight on this, thanks
@John Smith: The clock rate has been already set so don’t worry about it. The device on the left should be a router because the question states: “This topology contains 3 routers and 1 switch”.
the configuration are only required for the two new router right?
i am a bit confused with the subnetting for pc c ip address…
is the network really 192.168.152.224?
i have try to calculate it and i got 192.168.152.240 since the bits are 28…
how can i get 192.168.152.224?
can you explain???
makes me want to drink alchoholic beverages
can i know that there is any updated lab sim question from icnd1?
Passed with 960 today… this site was very VERY usefull.
@John, would you mind sharing with us the material you used ? Any hints. Thanks.
please can any one send me the latest sims . please help me i am taking icdn2 exam in 2 days my email is dennistekin@gmail.com
Hay i Passed with 860 Today (ICND 1)
This Question was asked..
Thank You 9tut.
I passed the 822 test yesterday and all of 9tut’s questions are on the test, just different numbers. KNOW THE PROCESS!
When is the last time the ICND1 test changed? Does anyone know.
I need your help, I passed ccent but I had 750!!!!
hi, new to the site, thanks.
…taking it on Friday — by force! May the force be with me….
WONDERFUL Post.thanks for share..extra wait ..
Dumb question — Is copy paste allowed in the lab sims during the test? just curious…
Hello Community,
I am kind of uncertain what topics i have to expect in the icnd1 to be. On Cisco’s Website the topics are described a little to general. Will NAT-configuration and debug commands approach in the exam?
Currently, I prepare for the ICND1 in self study, but, like I mentioned already, I am not sure what to practice.
@ CaptnSubtext
Just go through the cisco press book line by line from the beginning ..
It really helps..
I failed CCNA , then i took ICND1 via press book
All the topics you could possibly face will be clearly mentioned in the book..
All the best..
@DJ
Thanks for your reply, DJ.
I think, i have learned almost everything written in the ICND1 Book from Ciscopress, but when I read about the SDM I wondered if this topic could appear in the exam, too. The same with NAT. I am also a little insecure about the actuality of the topics described in the book because it is from 2007..
Took my 640-822 on 3/7/11 and passed on the first try with a 850. I had this sim and another one from this site. I only wish that I had found out about 9tut earlier, I didn’t prep enough with this information. This site is a great resource for practicing configs and troubleshooting. Kudos to you guys, and thanks so much for the help. Cisco press books are great for the fundamentals, but can’t stress enough how important practice with lab equipment and/or packet-tracer is vital to you passing. Thanks again 9tut, when I prep for my 640-812 I will practice extensively with these labs.
To CaptSubtext,
Read the cisco press ICND1 book from front to beginning and then practice subnetting until you can do it easily. Subnetting is vital and you need to use it in various ways to pass your questions in a timely manner. Try practice labs with packet-tracer if you don’t have your own equipment. It’s intimidating at first but as you get more comfortable with the material, you’ll recognize area’s where you are weaker in. Research on the best practice questions for the exam. I had about 10 to 15 questions that were very similar to the ones I practiced with troytech practice questions.
any way we can get a printed copy of all the SIMS for ICND1 & ICND2?
Thanks!
Hi All,
While the configuration is brilliantly worked out and explained, I am not entirely sure about the ‘correctness’ of the IP addresses assigned to 2 of the interfaces. I think this is a trick question to test your thought process, to see if you adhere to standards.
From the show running-config output, you worked out the following highlighted below:
YOUR TAKE:
1) ip address of Fa0/0 interface of the Main router is 192.168.152.177/28. This address belongs to a subnetwork which has:
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
MY TAKE ON THIS:
The configuration workouts are absolutely correct. However, the SIM/question gives 2 valid addresses in this subnet: 192.168.152.177/28 and 192.168.152.190/28.
You choose 192.168.152.190/28 for the Fa0/0 interface.
I think while this address (192.168.152.190/28) will work, it is not the correct address to assign to the router interface. It is defacto standard to assign the first available address to the router interface, therefore I would have choosen 192.168.152.177/28 for this interface.
2) The same thing for the serial interface.
You choose:
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
MY TAKE:
Same principle again. The SIM/question gives 2 valid addresses within this subnet block; 192.168.152.161/28 and 192.168.152.174.
As mentioned earlier, it is common practice to assign the first available address from the pool to the router interface, therefore, I would have choose 192.168.152.161/28 as the serial interface address.
One other thing that's puzzling from the show running-config output of the main router, is that it shows the clock rate on the serial interface. Considering this, would we not have to also configure the clock rate on the other router (router to right) connected to the main router through the serial connection???? Not entirely sure about this, so your thoughts would be welcomed.
Can someone please explain the whole assigning IP address’s part its the only thing that isnt clicking for me..
@Josh:
it’s simple:
+ you have an IP address (class A, B or C)
+ you have a subnet mask (something like 255.255.255.0). you need it to tell the computer on which network it resides.
+ you have a default gateway (for switches/servers/computers/other network devices that must communicate through the router). this is the IP address of the router that sends data (packets) from this network to other networks or directs data from other networks to a specific device on this network.
my advice: see cbtnuggets videos. there are 3 videos that explain IP addressing. you MUST learn IP addressing or you will certainly fail cisco exams. good luck
in response to Joe’s comments, you can’t choose the 1st & the last IP address in any subnet, therefore can’t assign 192.168.152.177/28, as its the 1st in the subnet range
HELP …HELP ..i need new update questions about current ICND1exam other than posted .
thanks !
longlife for 9Tut
I passed tonight with 975/1000. This question was there. Almost the same one.
Responding to Orals argument. Dude look at the the sh run command listed. .177 and .161 have already been assigned to the MAIN router.
hi all!
pls can any one pls help me with the latest ICND1 dumps my email is osman_1985@live.com
Hello 9 tut…. is it imperative that you type the full commands…eg “show run” instead of “show running-config “is it approved in the real exams?
@kwakutee
you should learn the full command. it worked for me to use short commands
@Kwakutee: You can use the short commands like “show run” but you should know the full commands “show running-config” because sometimes short commands don’t work.
this is in my yesterday’s test. I passed with 874. (804 was my pass line). Thanks for this web site.
Hello guys I took the test ICDN I today. I got 1000/1000. Thk a lot of this site. Don’t be affraid to do this test. Read the book (Odom), see the CBTNuggets, do labs using Packet Tracer and understand by heart Subnetting. I got the second question in my test.
can someone please send me the latest dumps. t.reynolds314@gmail.com
“Set the password to allow privilege mode access to privpw……” Hello 9tut…arent we supposed to use enable secret?..thnx
Facing the CCENT on Tues pliz send me the latest dumps b4 i sit.
@ Kwakutee
No, but you’re close, enable password privpw
,
“enable secret” encrypts current and all passwords.
Correction:
“enable secret” encrypts and overrides password that’s used to secure privileged mode.
Ex…
– The correct command “enable password privpw” will set a password to access privileged mode.
– This command “enable secret privpw2″ will override ” enable password privpw”.
So be very careful and pay attention to what thequestion is asking you.
Ex…
Set the password to allow privilege mode access to privpw = enable password privpw
Enable secret password to privpw2 = enable secret privpw2
Darkplayer
Enable secret only creates an encrypted password
Service password-encryption encrypts all passwords on the router
I am doing the ICND1 on Monday, can somebody send me the lattest dumps plz… proactiv123@yahoo.com
Wow I had no idea how to do these the first time I came to this site.
After going through my study material again (Chris Bryant Train Signal) and this website
http://www.subnettingquestions.com/ these sims aren’t difficult at all.
Quickest way to work out the subnetting questions are:
1. Look at the prefix notation or mask IE /16 or whatever it is.
2. Add up the amount of bits borrowed after the default mask is noted.
Eg. If the prefix is /28, the closest default mask is /24 or 255.255.255.0 or Class C
That means 4 bits were borrowed (28 – 24 = 4).
3. Now imagine those borrowed bits on the octet number line. IE.
128 64 32 16 8 4 2 1
1 1 1 1 0 0 0 0
(The 1′s are the bits borrowed.) Now add up those numbers above the 1′s.
128 + 64 + 32 + 16 = 240.
4. Take the ‘magic number’ 256 and subtract the 240 from it.
256 – 240 = 16.
So now we know 16 is the block size or increment number. Meaning the subnets
will go up in 16′s starting from 0. (Note ‘the magic number’ 256 is always used in
any example to subtract those borrowed bits.
5. Look at the IP address and then look at the the prefix. If the prefix is /28 we are working in the fourth octet of the IP address. 28 > 24. If it was /23 we would be working in the third octet of the IP address. They are directly related to one another regardless of value of the first octet in the IP address. Even if the first octet in the IP address is 172 but the prefix is /28, we still end up working in the fourth octet, not the third. When I say working, I mean where we are going to add up our block size or increment number.
So if its a /28, as we worked out earlier the block size is 16. Look at the fourth octet in the IP address. Count how many times 16 goes into whatever number is there.
IE. If the number in the fourth octet in the IP address is 34, we know that 16 goes into 34 twice, which equals to 32.
0 = first subnet.
16 = second subnet.
32 = 3rd subnet.
48 = 4th subnet
So 32 would be the subnet or network number. 31 would be the first host in that subnet. 32 would be the second host. The valid host range is always the block size – 2.
Reason for this is because the subnet number and the broadcast address do not count as valid hosts. So the last valid host in that subnet would be 46.
47 = Broadcast address
48 = Next subnet number
I’m still learning myself, but if anyone has questions about this I’d be glad to help.

Had this lab on my exam today. It was rough, I had 4 labs and 5 drag and drops. Passed with a 874. Goodluck!
What if the ip address of fa0/0 was 192.168.152.178 ?
Could 192.168.152.177 be used?
@Phenom, .177 is the network address, can not be used.
@BIGD, .177 is the first valid host on the .176 network. so Phenom is right.
I created this Simulation with Cisco Packet Tracer 5.3.2. Go to: http://www.box.net/shared/navc8p9fnvlz1bzm1m4q
and download the Implementation 2.pkt. Please let me know if this helps and please leave me any feedback. I am scheduled for my CCENT exam this coming Tuesday. Thank you 9tut, this site has been very helpful.
I also created the Implementation Sim at the same link for download. I hope this helps you like this site has helped me in my studies.
0 192.168.1.2 R1
*1 10.2.5.5 Sw1
Let supposed I want to open a telnet connection with ip address 192.168.1.2, which of the following commands I would used?
a. resume
b. connect
c. enter
d. resume 1
@king leo
D. resume 1
Do I need to configure the telnet and console password on the main router?
I passed my ICND1 today. Q.2 and Q. 4 were in the exam. Thnx 9tut.
@King Leo
I think you’re asking how to resume a session, correct? I logged into three routers (using Ctrl+Shift+6, x to exit out each time). I had the following three sessions from the router I telnet’d from:
router1#show session
Conn Host Address Byte Idle Conn Name
1 20.15.96.42 20.15.96.42 0 2 20.15.96.42
2 20.35.0.142 20.35.0.142 0 2 20.35.0.142
* 3 20.14.224.1 20.14.224.1 0 0 20.14.224.1
If I just press it will resume my session with the IP with the “*” beside it:
router1#
[Resuming connection 3 to 20.14.224.1 ... ]
If I want to resume a session with one of the other routers, I would use the command “resume” followed by the connection number. So, if I wanted to resume my session with 20.35.0.142, I would enter:
router1#resume 2
[Resuming connection 2 to 20.35.0.142 ... ]
somerouter#
Passed INCD1 today, sim #2 was on the exam.
Pass ICDN1 on jan 24th with a score of 974. I got this sim on the exam, thx 9tut
Guys, a stupid question. How would you know which ip’s to pick and assign to the routers on the left and the right side?
In the above Sim:
Network address: 192.168.152.176 (because 176 = 16 * 11 and 176 < 177)
and
Network address: 192.168.152.160 (because 160 = 16 * 10 and 160 < 161)
This simple equation looks easier than the process I am using to get the Network address.
Can anyone explain where the number 11 comes from in the first example and 10 in the second?
Thanks!
Sorry Guys for ask above, I just figured it out – Way too much studying last night .
9 tut, can you pls tell me how to use the Labsim? I have PT 5.3.3 but can not manage to open the Sims.
