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

Upon further checking, the Server who propagates all the vtp update and whose updates used by other client/servers will also use the md5 digest of that Server from show vtp status.
md5 digest is a composition of domain name, password etc. based on what I read.
passed today. Show VTP status command for Q6 in the exam didnt show the “configuration last modified by” line. I thought i am using the wrong command so i checked back here. I just made a guess based on 9tut question.
its over passed today and all was fine thanks 9tut
@ Phillip and Shashidhar
What SIM questions were inside the test ?
Was any other strange question for VTP sim beside the one referred by phillip ?
is this correct..?? there are 790 questions in that vce..can anyone please tell me how many questions actually have to study…
Cisco.ActualTests.640-802.v2012-09-27.by.nguinasoft.790q.vce
can anyone please give me a latest updated vce link to download…i have my exam in this 17th…
@9tut
please help me out with this question I’ve just finish my exam and i failed with 788/1000
(implement, verify and troubleshoot NAT and ACLs in medium-size Enterprise branch office network) is this question belong to ACL2 simulation? because i have done every thing in simulation accordingly i don’t know why they didn’t give me 100% or it is not allowed to ping every thing when checking that your configuration is well done.
please I’m taking back the exam on Monday.
tkx
Hi,
In one of the questions before questiong 9, The question asked us to identify 3 trunk ports and fa0/3 happens to be one of the trunk ports. I can understand if the question is from a different switch, but sw-ac3 has that port configured as a trunk port. How can another question on the same sim wants to identify the port as an access port? Please help out.
was there any option available????
@Mike
Please comment on dim’s post
“implement, verify and troubleshoot NAT and ACLs in medium-size Enterprise branch office network” is this question belong to ACL2 simulation? or how to solve this??
Please do something I am taking exam on 22 Oct.
@Arif
He must done something wrong, it is hard to say what exactly.
@dim
Would you please tell us the full question.
What was the requirements and you did what? Waiting for your replay.
@arif
Actually that came out on the score point from my result and it is showing that i got 0%, and im my exam i didn’t leave any blank and i was even confident with the respond i gave , my question is this which part of the exam this question”(implement, verify, and troubleshoot NAT and ACLs in medium-size Enterprise branch office network)” belong to? tkx again
@Phillip
Congrats on your successful test pass! I had the same problem. I am still waiting on Cisco and Pearson to return my dispute about this issue. I am sure you were using the same commands as you would need to answer the question like I did. Report it to Cisco and Pearson, please. Your report will make it known there could be an issue with the Sim.
@dim
I got a 40% on “implement, verify, and troubleshoot NAT and ACLs in medium-size Enterprise branch office network” even with me verifying my ACL worked. I was just as surprised as you were.
@9tut . I did my CCNA exam yesterday 15th October but i scored 788/1000. My score in implement, verify, and trouble shooting NAT and ACLs in a medium-size Entrprise branch office network was 40%. i was wondering where the problem came from coz in this segment my question was (2,4, 6, 7, 8). But Q8: had a slight changes
Q8: Which of the ports will a frame be forwarded that has a source mac-address (changed)0010.5aoc ff9f (fa 0/1) and destination mac-address 0008a.88a47.e612 (not present in the mac-address table). (Choose two)
1. – Fa0/8
B – Fa0/3
C – Fa0/1
D – Fa0/12
B and C is the answer based on this question.
The thing is that u just have to understand the concept , don’t crame the answers coz there might be some changes.
@anonymous , i think the problem has to do with the Access-list Lab question. i was sure i created my access-lit very well, but i did not verify my configuration. i think we need to verify the configuration by typing the http address of the finance server, on the system and make sure that it is only the computer that is allowed access that will access the browser , and also go to other hosts on the LAN and typ the http address of the Finance web server(http://address) and make sure they can not access the browser.
Another thing i forgot to do was that i didn’t save my configuration.
I did not know if that affected my score..
@zee,
Please tell me what are some of the questions that you have seen in your exam sim(vtp and acl scenario)? Please help me i have exam tomorow
@Anonymous . Did Cisco and Pearsonvue gave you any reply based on your request. Or probably there was a problem with the Lab Question.
@Zee, @Dim
I think when the question is about ” verify, and trouble shooting NAT and ACLs in a medium-size Entrprise branch office network” This has something to do in troubleshooting or implementing Network Address Translations(NAT) and not just focus on ACL because most of the ACL on NAT are just standard access list.
Hi guys..im from Sri Lanka,,i did my CCNA exam 2day,,all the questions are very similar to 9tut questions,,passed my exam with 960/1000,,,great to pass my xam..for all the CCNA candidates,,im saying don’t be afraid or don’t hesitate to do the exam..i faced to 50 questions with 3 labs,,all the labs are same as here only the ips and some details are changed,,sims are VTP,EIGRP,ACL 2,,so go on guys..cheers,,,,,
;
Zinchemosh pls, which dumps did you used to prepare for the ccna exam. Did you also see the question verify and trobleshoot NAT and ACL
I appeared for the exam and had the trouble typing Letter C in show mac address-table and could not complete my lab and had a very huge issue with CISCO & Pearson and finally gor a retake voucher for free. My question is what should I do if again I am unbale to type letter C Is there other command besides show mac address-table or show mac-address-table. My retake is on 18th Oct. Any guidance would be really appreciated
Hey I am not sure if we need to verify anything after the configurations are done. For ex, with acls… I did verify the connectivity by trying to reach server (for example). But still I see around 40% score on that. Something seems to be wrong.. or I am missing something..
Any help is greatly appreciated.
@Richard I used shekar and napolean dumps mostly..nope i didnt find any NAT but got ACL,,believe me CCNA is not that hard,,:) all the questions are very similar to 9tut and these dumps..im planning to to do CCNA security now..
Pls can any one who passed ccna exam recently tell me the dumps he used.
Hi guys! Just want to ask to those who take their exam last week. What was the topics included in the lab? Thanks.
@Richard just search in google u can find a lots of thm,,o this is the link for shekar dump..http://www.examcollection.com/cisco/Cisco.ActualTests.640-802.v2012-07-15.by.Sekhar.697q.vce.file.html
it’s really complicated … i didn’t understand how this will come in the exam ??
@9tut and @All
Some people say that they got a strange sim about NAT and ACL
“Implement, verify, and trouble shooting NAT and ACLs in a medium-size Entrprise branch office network”
and also they can’t get above 40% marks.
What is the requirements of this question and how to solve it.
Please answer this question. I am taking exam on next week. Please…
@Zee
“Implement, verify, and trouble shooting NAT and ACLs in a medium-size Entrprise branch office network”
was this a sim or just questions? n how many questions please
Attention everyone! I have news from the Cisco front in regards to the last line being missing from the VTP Status page. I have been given a voucher towards a retake due to the simulation being faulty. I am taking it again this Friday. If I see any other further errors on this same matter, I will let you all know!
wow that’s great hope we all make it this week
@Anonymous
Great. Good luck for your exam and please share your experience after exam.
@ Anonymous
thats awesome and good luck on Friday.
@Arif & @ @ Anonymous
whats alll about this question?
“Implement, verify, and trouble shooting NAT and ACLs in a medium-size Entrprise branch office network”
is anyone else having a problem seeing the the mac address on question 1 on packet tracer?
Hi guys, would like to ask about an update regarding the exam.. what are the latest set of laboratory simulations on the actual ccna exam? is it still EIGRP, VTP and ACL2? will be havin my exam by monday 22nd of oct..
thanks and best regards.. :)
@ Eric
Actually i do not know about
“Implement, verify, and trouble shooting NAT and ACLs in a medium-size Entrprise branch office network”
Please see posts of @dim, @zee, @CCNA and @Oct29.
@Phillip
How is that possible ? the line “configuration last modified by” not shown. ?
may be they did a trick and change the vtp password on both end switches.
if vtp password on both switches are change no info will be shown.
Passed my ccna exam just now and scored 881/1000. All 3 lab are the same, only ip add differ, but becareful there some strange question which are not in the dumps. Thanks to 9tut, cbtnugget and examcollection.
@Waleed
It is very possible. The line”Configuration Last Modified…” was not shown on my last exam. I reported it to Cisco, and they are paying for my retake. I do not know about any tricks. I will let you all know about it tomorrow when I take the exam again.
Guys,
I have passed CCNA a few days ago with ~980/1000.
SIMs were VTP, ACL2 and EIGRP.
On VTP SIM I experienced the known issue with the missing line “Configuration Last Modified…” while executing the “show vtp stat” command. This is probably a bug, since after executing 3 times the same command the “Configuration Last Modified…” was still missing. During the 4th execution of the “show vtp stat” command and after pressing 2-3 times the “enter” key, the “Configuration Last Modified by…” line finally appeared.
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.
A little advice to you guys.
It does not worth to learn by letter all of the questions from 9tut or from any dump. Try to study and get tne concept of CCNA.
Buhari pls tell me, which of the dumps did you use. And what are the 3 lab sim you saw.
@Anonymous
Thanks for sharing your experience.
@Anonymous
Thanks for sharing your experience :)
can anyone give me the latest dumbs pls.. psanathanan@yahoo.com
i will take the exam soon
Hi Guys,
My CCNA exam is tomorrow ,can you help me with the SIM’s that are being asked.
for the ACL2 THIS WAS MY Q
Host C should be able to use a web browser(HTTP)to access the Finance Web Server
- Other types of access from host C to the Finance Web Server should be blocked
– All access from hosts in the Core or local LAN to the Finance Web Server should be blocked
- All hosts in the Core and local LAN should be able to access the Public Web Server
Only the ip address changes
my answer was
access-list 100 permit tcp host 192.168.175.3 host 172.22.81.17 eq 80
access-list 100 deny ip any host 172.22.81.17
access-list 100 permit ip any any
int fa0/1
ip access-list 100 out
end
copy running-config startup-config and i got 100% on the sim
remember-
the Implement, verify and troubleshoot NAT and Acls in a medium -size Enterprise branch office network is the ACL,NAT question in general BUT cisco is only using ACL2 FOR NOW WHICH IS THE ON ABOVE,so no need to worry,but my advice is you just have to know them all in case cisco changes their questions,
my eigrp was the same as here only the ip address that changes
my vtp was QUESTION,1,5,6,7 AND (8) but the 8 question was change to ip address which i would like guys to comment about the question says—
Out of which ports will a frame be forwarded that has source ip-address 192.168.34.2 and destination ip-address 192.0.23.1? (Choose three) i just guess on this one.
finaly my score was 967,my dumps were brar,sekhar,cbt neget,examcollection and above all 9tut thank u a
@Richard,
I used Jerico and Sekhar Dumps from examcollection.com they are valid one, regarding the Labs I saw Access-list 2, vtp and EIGRP Lab they are the same with the one in 9tut the difference is only in ip address. also try to download packet tracer v5 and these 3 lab to practice.
Goodluck.
@ (Other) Anonymous,
Thank you for the insight to your sh vtp stat issue that I ran into. I will try hitting the enter key like you did if it happens again to me in less than 3 hours. Congrats on your passing the exam!
@ Everybody
Is it necessary to maintain sequence for drag and drop?
In dumps when i practice and arrange correct answer but not in sequence loose points.
Any comments please.
