CCNA VTP SIM Question
Question
This task requires you to use the CLI of Sw-AC3 to answer five multiple-choice questions. This does not require any configuration.
To answer the multiple-choice questions, click on the numbered boxes in the right panel.
There are five multiple-choice questions with this task. Be sure to answer all five questions before leaving this item.
Notice: All the images in this VTP LAB are used for demonstration only, you will see slightly different images in the real CCNA exam. You can download this sim to practice here (but notice that this sim is not perfect, only for practicing purpose): http://www.9tut.com/download/9tut.com_CCNA_vtp_sim.pka
If you are not sure about VTP, please read my VTP Tutorial
Note: In this VTP sim, you have to answer 5 questions. After answering the first question, click on the number boxes to move to other questions. If you click “Next” at the first question, you will lose points for 4 remaining questions.
Question 1
What interface did Sw-AC3 associate with source MAC address 0010.5a0c.ffba ?
a) Fa0/1
b) Fa0/3
c) Fa0/6
d) Fa0/8
e) Fa0/9
f) Fa0/12
Answer: Fa 0/8
Explanation: to find out which interface associated with a given MAC address, use the show mac-address-table command. It shows the learned MAC addresses and their associated interfaces. After entering this command, you will see a MAC address table like this:
From this table we can figure out that the MAC address 0010.5a0c.ffba is associated with interface Fa0/8.
Note: There are some reports that the “show mac-address-table” command does not exist in the exam. So in the exam, if you cannot use the “show mac-address-table” command then try using the “show mac address-table” (without “-”) instead.
Question 2
What ports on Sw-AC3 are operating has trunks (choose three)?
a) Fa0/1
b) Fa0/3
c) Fa0/4
d) Fa0/6
e) Fa0/9
f) Fa0/12
Answer: Fa0/3, Fa0/9 and Fa0/12
Explanation: Use the show interface trunk command to determine the trunking status of a link and VLAN status. This command lists port, its mode, encapsulation and whether it is trunking. The image below shows how it works:
(This image is used for demonstration only)
Question 3
What kind of router is VLAN-R1?
a) 1720
b) 1841
c) 2611
d) 2620
Answer: 2620
Explanation: VLAN-R1 is the router directly connected to Sw-Ac3 switch, so we can use the show cdp neighbors command to see:
1. Neighbor Device ID : The name of the neighbor device;
2. Local Interface : The interface to which this neighbor is heard
3. Capability: Capability of this neighboring device – R for router, S for switch, H for Host etc.
4. Platform: Which type of device the neighbor is
5. Port ID: The interface of the remote neighbor you receive CDP information
6. Holdtime: Decremental hold time in seconds
Sample output of show cdp neighbors command:
One thing I want to notice you is “Local Intrfce” in the image above refers to the local interface on the device you are running the “show cdp neighbors” command
Question 4
Which switch is the root bridge for VLAN 1?
Answer: Sw-DS1
Explanation: First we use the show spanning-tree vlan 1 to view the spanning-tree information of VLAN 1
From the “Cost 19″, we learn that the root switch is directly connected to the Sw-Ac3 switch over a 100Mbps Ethernet link
Notice that if you see all of the interface roles are Desg (designated) then you can confirm Sw-Ac3 switch is the root bridge for this VLAN (VLAN 1).
If you see there is at least one Root port in the interface roles then you can confirm Sw-Ac3 is not the root bridge because root bridge does not have root port. In this case, we notice that the root port on Sw-Ac3 switch is FastEthernet0/12, so we have to figure out which switch is associated with this port -> it is the root bridge. You can verify it with the show cdp neighbors command:
The “Local Intrfce” column refers to the interface on the switch running “show cdp neighbors” command. In this case, Sw-DS1 is associated with interface FastEthernet0/12 -> Sw-DS1 is the root bridge
Question 5
What address should be configured as the default-gateway for the host connected to interface fa 0/4 of SW-Ac3?
Answer: 192.168.44.254
Explanation:
First we have to identify which VLAN interface Fa0/4 belongs to by the show vlan command
From the exhibit we know that VLAN 44 is configured on router using sub-interface Fa0/0.44 with IP address 192.168.44.254/24
Therefore the default gateway of the host should be 192.168.44.254
Question 6
From which switch did Sw-Ac3 receive VLAN information ?
Answer: Sw-AC2
Explanation: to view the VTP configuration information, use the show vtp status command
So we knew Sw-Ac3 received VLAN information from 163.5.8.3 (notice:the IP address may be different). Finally we use the show cdp neighbors detail to find out who 163.5.8.3 is:
Note: If in the exam you find that “Configuration last modified by 0.0.0.0” then “0.0.0.0″ here indicates it does not receive VLAN information from anyone -> Sw-Ac3 is also the local updater. Therefore the answer in this case is Sw-Ac3.
Question 7
Refer to the exibit, SwX was taken out of the production network for maintenance. It will be reconnected to the Fa 0/16 port of Sw-Ac3. What happens to the network when it is reconnected and a trunk exists between the two switches?
A – All VLANs except the default VLAN will be removed from all switches
B – All existing switches will have the students, admin, faculty, Servers, Management, Production, and no-where VLANs
C – The VLANs Servers, Management, Production and no-where will replace the VLANs on SwX
D – The VLANs Servers, Management, Production and no-where will be removed from existing switches
Answer and Explanation:
First we should view the VTP configuration of switch Sw-Ac3 by using the show vtp status command on Sw-Ac3
Notice that its configuration revision number is 5 and VTP Domain Name is home-office
Next, from the exhibit we know that SwX has a revision number of 6, which is greater than that of Sw-Ac3 switch, and both of them have same VTP Domain Name called “home-office”.
Therefore SwX will replace vlan information on other switches with its own information. We should check vlan information of Sw-Ac3 switch with show vlan command
So the correct answer is D – The VLANs Servers, Management, Production and no-where will be removed from existing switches
Please notice that in the real CCNA exam you may see a different configuration revision of Sw-Ac3 or of SwX. In general, which switch has a higher revision number it will become the updater and other switches will overwrite their current databases with the new information received from the updater (provided that they are on the same domain and that switch is not in transparent mode). In particular, if the revision number of SwX is lower than that of Sw-Ac3, the answer should be “C – The VLANs Servers, Management, Production and no-where will replace the VLANs on SwX”.
Also, some recent comments have said that the new switch’s VTP Operating Mode is Server but the answer is still the same.
Note: If a switch is in client mode and has a higher Revision number, it can still update other Server switches (with lower Revision numbers).
Question 8
Out of which ports will a frame be forwarded that has source mac-address 0010.5a0c.fd86 and destination mac-address 000a.8a47.e612? (Choose three)
A – Fa0/8
B – Fa0/3
C – Fa0/1
D – Fa0/12
Answer: B C D
Explanation:
First we check to see which ports the source mac-address and the destination mac-address belong to by using show mac-address-table command
We notice that the source mac-address 0010.5a0c.fd86 is listed in the table and it belongs to Vlan 33 but we can’t find the destination mac-address 000a.8a47.e612 in this table. In this case, the switch will flood to all ports of Vlan 33 and flood to all the trunk links, except the port it received this frame (port Fa0/6). Therefore from the output above, we can figure out it will flood this frame to Fa0/1, Fa0/3 and Fa0/12.
Please notice that the “show mac-address-table” command just lists information that was learned by the switch, it means that there can be other ports besides Fa0/1, Fa0/3 and Fa0/12 belong to Vlan 33. You can use the show vlan command to see which ports belong to vlan 33
And we found other ports which belong to vlan 33, they are Fa0/2, Fa0/5 and Fa0/7. Our switch will flood the frame to these ports, too.
And we can check which trunk ports will receive this frame by the show interface trunk command
-> Port Fa0/9 will also receive this frame!
Note: Some reports said there is another version of this question. A reader on 9tut commented:
Another question on the VTP SIM was” What will be the destination MAC address of a packet with Source IP address 192.168.44.1 and destination IP address 192.0.2.X (doesn’t really matter what will be the Dest. IP address, since it will be sent to the router).
The answer is simple:
Since the source IP address belongs to VLAN 44, the default gw of the sender is the Router’s Subinterface 192.168.44.254, and this is where the packet will be sent. Thus, you need to perform a ‘show cdp nei’ on the Sw-AC3 in order to find the local FastEthernet port where the router is connected. Then execute a “show mac address-table” (this command was functioning) and find the mac address associated with the previous port. This is the answer.
Question 9
If one of the host connected to Sw-AC3 wants to send something for the ip 190.0.2.5 (or any ip that is not on the same subnet) what will be the destination MAC address?
Answer and Explanation:
Because the destination address is not on the same subnet with the switch, it will forward the packet to its default gateway. So we have to find out who is the default gateway of this switch by using the show running-config command
From the output, we notice that its default-gateway is 192.168.1.254. In fact, we can easily guess that its default gateway should be a layer 3 device like a router; and in this case, the VLAN-R1 router. To verify our theory, use the show cdp neighbor detail command and focus on the description of VLAN-R1 router
From this output, we can confirm the switch’s default gateway is VLAN-R1 router (with the IP address of 192.168.1.254). And “the interface: FastEthernet0/3″ tells us that the switch is connected to VLAN-R1 router through Fa0/3 port (Fa0/3 is the port on the switch).
Finally we just need to use the show mac-address-table command to find out which MAC address is associated with this interface
(Notice that in the real CCNA exam the MAC address or port may be different)
And we find out the corresponding MAC address is 000a.b7e9.8360. Although there are some entries of port Fa0/3 with different Vlans but they have the same MAC address

Question 9
If one of the host connected to Sw-AC3 wants to send something for the ip 190.0.2.5 (or any ip that is not on the same subnet) what will be the destination MAC address?
Answer and Explanation:
Because the destination address is not on the same subnet with the switch, it will forward the packet to its default gateway. So we have to find out who is the default gateway of this switch by using the show running-config command
@farrukh
I am facing same difficulties… can any one please clarify it.
@farrukh, @Michael,
in the provided packet tracer file here, they have not set the default gateway. That’s why you don’t see it by running “show run”. give it a try by setting it yourself with “ip default gateway x.x.x.x” global config command and you’ll see that the default gateway you set appears on sh run after that.
The answer for Question 9 is correct but the explanation is not correct!
“Because the destination address is not on the same subnet with the switch, it will forward the packet to its default gateway.” => OK, TRUE
“So we have to find out who is the default gateway of this switch by using the show running-config command.” => WRONG EXPLANATION!
Reason: The attached host can belong to any of the vlans available. Only if the host belongs to the same management VLAN as the switches, is when it will have the same DG as the switches.
A better way to understand this can be found at this link Sameer above has posted:
http://blog.acmeinfotek.in/2013/08/ccna-vlan-simulation.html
Basically we have the router-on-a-stick scenario here, with the switch having multple vlans. So there will be a trunk link to the Router where it(the Router) uses sub-interfaces to support dot1Q encapsulation. These sub-interfaces are shown in the figure above.
What we need to unserstand is that with routers, all sub-interfaces of a main interface have the SAME mac-address as the main interface. So for exame fa0/0.44 above will have the same mac-address as fa0/0.
So any host attached to the switch, when it wants to send a packet outside it’s subnet will be sending it to it’s default gateway. which will be either one of the fa0/0 subinterfaces listen in the above picture.
but as mentioned, the detination mac address will be the same for any of those gateways as it’s the same MAC address as the fa0/0 interface
so we just have to found the MAC address of the Router interface that is connected to the switch. To do this we simply use “show cdp neighbors” command to find which port of the switch is connected to the router.
Then a simply “show mac address-table” command to find the mac-address of the router interface connected to the switched port will do the trick! As this will be the mac address used by the host to send the packet.
here’s another very interesting discussion and especially note this helpful answer where alternative solutions to find the DG are listed:
https://learningnetwork.cisco.com/message/102762#102762
@ faruk @michael and friends …..
the reason the mac address 0010.5a0c.ffba and the default gateway is not showing is very simple reasons. no ip adds have been configured in the host computers and default gateway is also not configured. So when u type sh mac address table command it is showing only directly connected devices i.e. Sw-AC2,Vlan-r1 ,Swds1 .etc .the sh cdp ne shows exactly the same info as sh mac add-table. So the switch or any device for that matter will know about the mac of the host comps in its vlan 1 when it successfully pings and gets reply. then the entry is made into the mac address table. so the simul packet we downloaded is incomplete or not configured completely ..in short not fully configured topology as shown above in this site.!!!. I asigned ip for vlan 1 and assigned ip address to host comp and made a ping request from the switch to the host .After successfully reply the mac address showed up in the mac address table !! u can try it too !
Hi All,
passed yesterday with 933/1000.. I studied Cisco.Acme.640-802.v2013-08-06.by.Acme.649q.vce dumps and its 100% valid and i got only one new question out of this dump. Simulations were VTP, ACL, EIGRP with AS 222 and one Passive Interface towards the ISP.
i also used acme blog from vce.
http://blog.acmeinfotek.in/2013/08/ccna-eigrp-simulation.html
could you please answer this questions for me Please!!
1) In the sims after I put copy running-config startup – config do you hit enter or space bar to save it. please answer clearly.
2)I hear lot of comments about the tab key. Is this to auto complete the commands in labs?
If I use is it ok or will the take points off?
3) What is the ? for in lab sims and when is it necessary to use it
please answer
hi all,
i passed yesterday with 973/1000…i followed spike 670q nd 9tut..all the question was easy..but there is little to worry about question no 9 of vtp sim..i did not get the ans as told by this explanation..
@Sonagre
You should master the SIM’s and dumps. If topic is confusing you can go to the video tutorials or search the topic on google. Pray also for blessings to pass the exam. Good Luck!
p.s.
for SIMS go to 9tut
for dumps try spike 662
Hi All,
I am going to take my exam in the middle of this week, but i am nervous about WLANs questions. can anyone please tell me if it is more important for 640-802 exam? if yes, then i need to start my focus on it. Thanks in advance.
Hi there! Question 9 explication has no logic what so ever! The switch will never look for IPs inside the frames, it will only look at MAC and VLANs!
For both the initial Arp and afterwards comunication the MAC destination will be the MAC of the hosts default gateway not of the switch!!! Because we do not know more detail on the host belongings we know that definetely it will go towards Vlan-R1 router.
1. Now we only have to see what is the local switch port connected to the router using SW#show cdp neighbors
2. With the local port determined we issue SW#show mac address-table and see what MAC’s were learned via that port. Because it is a network segment with only 2 devices of course there will be a single MAC learned no matter if it is for fa0/0.1;0/0.22;0/0.33 or fa0/0 and VLANs on which they were learned.
Once again I state: there’s no IP operations involved in a L2 switch for the hosts. The default-gateway of the switch is only for communications originating for or from the switch.
@Alex
check this one. I got this link from above post.
http://blog.acmeinfotek.in/2013/08/ccna-vlan-simulation.html
I am going to write my CCNA soon n i feel confident already :D….thnx in advance 9tut
FOr Question 9, The MAC address is 000a.b7e9.8360 is the source MAC address right?
Question ask for destination MAC address, it should the MAC address for the port connected to the switch right?
Does the drag and drop is to be answered following order? (where no order is mentioned)
@ PrankProxy on Sept 2nd FRAME RELAY really on the SIMs? That would be 4 SIMs. Is this a prank or are you serious? Most everyone is saying only ACL2, VTP and EIGRP on SIMs. Please do not mess with us. It is not funny. If anyone else got Frame Relay please confirm even though anyone can make up names. I did not play to study FRAME RELAY SIMs.
**It’s a Rubicon**
took ccna exam 9/6/13 labs were acl2,eigrp,VTP. Show mac-address-table command wasn’t working in VTP lab. FYI
@CiscoEr – NO Frame Relay Sim on exam again only acl2,vtp,eigrp
@Terry thank you. Many questions from 9tut? Exam collections? for EIRGP passive-interface?
When using SHOW RUNNING-CONFIG How you see a broader or entire output other than having to repeatedly hit CR or ENTER on keyboard at every —- more —- I have tried some key combinations but none works and hitting CR so many times just to get to the end of the commands output is very time consuming. Thank you
** It’s a Rubicon**
tab option works in sims………….not work in vtp sim……….I passed with 881 ………read spike 670 and 9tut……….you will pass easily……..just be cool ……and rock the exam……..
Today on exam !!! Cool !!
EXAM IS SO VERY HARD!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! STUDY STUDY AND STUDY !!!!!! WISH YOU GOODLUCK TO ALL !!!!!!!!!!
Cleared the exam today with 922…thanks 9tut more power! God bless..
Sim (ACL2, EIGRP with AS12, VTP)
Study harder + Prayers = Success
CCna is up
Sat exam today failed ;( 750-820 eigrp lab I done multiple choice lab I done access_list I messed up can someone help me thomasbulloch1988@gmail.com
i’ve failed this test 6 times. It’s down to the wire now since the test is changing. MEMORIZE every word of EVERY question! Unless you work with this stuff it’s confusing.
Before actual exam start (there is a tutorial first) exactly like this
http://www.cisco.com/web/learning/wwtraining/certprog/training/cert_exam_tutorial.html
@ Ragol congrats and thanks for the tutorial link. Watching it now. Yikes, cannot revisit a question!! That confirms it. Many questions from 9tut? How long did it take you?
**It’s a Rubicon**
@CiscoER thanks and your welcome. Right from the start Q2 I got acl2 sim it shocked me. 50 Questions all in all, right in middle or in between or last the sim question will appear just be ready at all times and lastly read the question carefully because some question are here in 9tut but they reconstruct it although same thought but the most important things is understand every question.
Tutorial – 15mins
Actual Exam – 120mins (I took it about 1hr and 45mins)
Surevey – 5mins
Hope this info would help you.
I passed today with 907 points. Thanx for 9tut. There were some tricky ipv6 and frame-relay question, but most of all were from here. Labs: ACL2, VTP, EIGRP.
Thanks 9tut. Passed today with 986 points. VTP, ACL 2 and EIGRP were there. Valid dumps are spike, sekhar acme. Special thanks to CBT Nuggets video series. Todd Lamle and evry body that commented on 9tut. Starting preparation for CCNP right away.wao!!!!!!!!!!!!!!!!!!!!!!!!!!
Review approved 894/1000, ACL Laboratories LAB EIGRP VTP sim2, the questions are the same that appear in examcollection and 9tut, I recommend studying quite the drag and drop and logically We understand and memorize the questions well, success to all who are to give their 640-802
Examen aprobado 894/1000, laboratorios VTP EIGRP ACL LAB sim2, las preguntas son las mismas que salen en examcollection y 9tut, recomiendo estudiar bastante los drag and drop y logicamente enteder y memorizar bien las preguntas, exito a todos los que estan por dar su examen 640-802
oye cual de examcolletion ?
hi am taking exam on 30/9 please update me
Hey guys, just put it to bed with 1000 out 1000 :) I just want to make a few comments here. Acme and Spike dumps are valid, all the questions were from there. There are several wrong answers in these dumps so I would recommend checking Karven’s dump, now he is working on these issues. The Labs were all from 9tut, quite easy deal. In ACL, the last request was all hosts should have access to Public Serve, I used “permit ip any any“ so this should be the right choice. In VTP lab, when I entered the show spanning-tree vlan 1 command, initially I was not able to find the root port, as it was the last line in the output, so you will need to hit “enter” a few times and it will show up. The EIGRP lab, easy as hell, the same as the one in 9tut, but with AS 2.
Thanks Acme, Spike, Kraven and 9tut :) Good luck guys, and remember that you have 2 weeks more to take this already very well known exam :)
@vasil
hi, i’m about to take the exam by friday. do you know where to find karven’s dump. thanks.
Just cleared the exam today courtesy of 9TUTS.com……….got a score of 1000 my labs were ACL,VTP and EIGRP did my exam before 55 minutes……….
Passed today with 960/1000.
Lab sims as indicated MAXWELL were VTP, ACL 2 and EIGRP.
In VTP lab, for some reason command #show vtp status didn’t show line “Configuration last modified by” so had to guess correct option.
I used Mashti, Kraven and Acme dumps for preparation. Some questions in these dumps are wrong, but 97% of them are correct and helped a lot.
Please are the labs displayed above the same in real exams. they are dated February 2012. please respond urgently.
Alhamdulilah.
Today i make it, passed CCNA 640-802 with 907/1000.
Goold Luck to All.
I have a question, I took 640-802exam yesterday and scored 762, too bad, wasted allot of time in VTP finding where my switch got his information, before I knew it I have only 20mins, I started rushing things and I believe I didn’t do well on that VTP SIM, my bad. Am planning to retake it again. will the SIM and the exam be alike or will it be more harder ? Please assist me on this, am ready to face it again, am not backing down.
Thanks.
kaycee, labs are mostly the same (well, topology doesn’t differ at least), there might be slight changes like in ACL2 Lab host which is allowed to access Finance Web server or some specific values but if you got the main idea and understanding it doesn’t matter that much.
I was scared when the site went down. Welcome back 9tut.com. Life is beautiful now.
@ wang the Karven’s dumps are at http://www.examcollection.com you will need a VCE reader to read the questions. Cost about $30.00 Download it right there from the site. Its VALID.
Okay, I got it to work under Mac OS X. It is pretty raw, but groovy anyway.
Renewed my CCNA after so many years, EIGRP LAB SIM (wrong AS and missing network statement) and Access-list SIM came up.
Many many thanks to 9tut! God bless you guys…
i have cleared the exam successfully i got material from this link all the best for you all (( http://demo.urlshortenerscript.net/2f5 )) all the best
There are 8 incorrect questions in dumps. Please refer
