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

Didn’t make it with a 788,
Little strange, acl2 sim was Q5. Freaked me out a bit, then it was worded a little differently then what I’ve seen… I spent too much time on it…
Anyways, what happens on the retake? am I guaranteed different SIMs/questions, or is it still random? Thanks
@ ragol on Sept 11, thank you. WOW exam 120 mins? That’s much better than the 90 minutes I thought it was. An additional 30 minutes is gigantic. I hope there is some count down timer on the computer to let us know our time.
@CiscoER not sure whats going on here but it’s always 90 mins
Going to write my exam on 23rd of sep…. Can i get a video Tutorial for this simulation.
if any one knows the link for the video tutorial,pls let me know

i just pass CCNA today with 973 point! thanks 9tut! thank you for providing us with the questions and complete explanations. very, very nice!
in my exam are the vtp sim, eigrp sim and the access-list sim.
good luck everybody.
I just passed CCNA today with a score of 828!
Thanks 9tut@ Most of the questions from here and the dump by Spike is valid!
VTP, ACL2, EIGRP Sim..
Just wanted to ask.. in my preliminary score it’s written that after review and analysis if score is not good, it will be classified as indeterminate.. what does that mean???
hi Nik, just go towww.pearsonvue.com/authenticate to check the offical result. i have checked it
after 2 hours from exam completion and i can see my grade is PASS!
i think cisco need time to confirm with the test centre before offical confirmation.
Hi, Anonymous.
Yeah, I went there.. it showed pass.. but then there was something written in preliminary score card, what was that?
I was just cleared with the margin of 3 marks..
dony worry nik, i can see the same thing(indeterminate) written on my prelim score sheet too!
it said score over 825 is a pass, then it is a pass! you have calculated it with top
precision. well done.
Please can someone help me on this question, I took the exam on Wednesday and scored 762 and am planning to retake it again next week Friday, will the sim be ACL,EIGRP,VTP or any other thing ?
ive got confused how to answer those questions ?
should i have type it ? ex fa0/8 ? like that
can anyone who has tried to take the exam answer this question:
when taking the actual exam on vtp sim or any sim what if you have your own shortcut of finding the answers (like not following the steps here or what commands to run), is that a deduction on your final score? or do you have to follow every command that is explained here?
thanks.
hi wang,
i just passed the ccna yesterday. my feeling is that the sim need you to answer 5 mc questions,
as long as you get the correct answer you will get points.
i dont think cisco will count you how many command typed are related to solving the question or
how many are not to adjust the point. or someone typed the ? command will get less point than
anyone who doesnt.
its’ just my feeling though.
@anonymous:
thanks for that and congrats btw :)
9tut – Your statement on Q7 is: “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)”. I thought this to be plainly INCORRECT. How can VTP Clients in the domain update VTP Servers? But then I went back and reviewed “How a Recently Inserted Switch Can Cause Network Problems” in Design Tehnotes, “Troubleshooting VLAN Trunk Protocol (VTP)”, Document ID: 98155,
http://www.cisco.com/en/US/tech/tk389/tk689/technologies_tech_note09186a0080890613.shtml
Clearly stated there, “This occurs whether the switch is a VTP client or a VTP server. A VTP client can erase VLAN information on a VTP server. You can tell that this has occurred when many of the ports in your network go into inactive state but continue to be assigned to a nonexistent VLAN.” All because the Revision ID of the inserted switch is higher. WOW! Thanks for a great SIM.
what will be the time given for exam to complete – “CCNA 640-802″
can anyone help me pls …….
I am at to write CCNA exam.. I am having a doubt … whether all the nine questions appear in the exam or out of this only 5 questions appear?
please reply
I just passed CCNA today with score 894.
Thanks 9tut!
Tips:
> just study the latest dumps (even one dump). keep on answering and understand it with supplement books like todd and wendell.
> study all the questions in at 9tut. Sims here at 9tut : ACL, EIGRP, swithing (about AC-SW3) came out on my exam.
> Don’t be tense during the exams. if you master the dumps, it seems like your answering the dump questions.
Good luck ccna takers!

I just passed CCNA with 933/1000. I used Cisco.Acme.640-802.v2013-08-06.by.Acme.649q.vce, 9tut.com, blog.acmeinfotek.in.
This dumps and simulation are so valid.
nain,
my exam this morning was 90mins with 50 questions. i finished my exam with 30min left. may be all the exams are 90 minutes. don’t stay too long on one questions. you have to manage your time.
Just read my post to day.
Good luck!
cleared my exam and i got the pass4sure dump from this link study material also
avaiable (( http://demo.urlshortenerscript.net/2f5 )) all the best..
hi nain,
the ccna exam is 90 mins, but if your native language is not english, you will be given
an additional of 30 mins.
@Richard & Anonymous,
Thanks a lot, I will try to do my best.. :)
Hello everyone
i passed the exam 640-802. the labs were (ACL , EIGRP, VTP)
a special thanks to 9tut for their efforts.
i got 5 question on vtp ,2 of them were same as here.
EIGRP was similar too and i got a passive interface on one of the routers
dont ask me about the ACL coz i did it in only 2min! was 4 statements and you should’ve done it in only 3 lines.if your taking the exam before 30SEP focus on the labs and try different situations, lots of questions from spike dump (its valid), and remember time is your enemy specially on the labs.
hello,
In exams, whether we should type the commands only once ? Or we can try many times, if it becomes mistake first time ?
can you suggest me pls.
Hi Maice,
You can try it many times only for VTP simulations(if u have enough time to do that).
But for doing this in EIGRP and ACL2, will cost marks i suppose.
i dont think it will cost you mark if you type more command than necessary or you come across
some bad commands, even in the simulations eigrp/acl.
you can even revert some wrong configurations by using the no command. as long as your final
configuration is correct. you will get full marks.
cleared my exam and i got the pass4sure dump from this link study material also

Hi,
I took the exam today and the labs are VTP (as just said here, MACs and ports are different), ACL2 (with all the variances) and EIGRP. Practice a lot on them. Another great link for help is http://blog.acmeinfotek.in/2013/09/incorrect-questions-in-ciscoacme640.html
nain,
don’t just try your best. just study the dump most of the questions are there. i tried many dumps, but most are the same.
hi,
does anyone know where to download vce but not the trial one? i have been looking for one but i always get the trial version. thanks.
Hello guys, I have a question… In the exam, do I have to save the configuration in the VTP lab?
I’ve seen two comments so far..one being on 9tut and the other one Exam Collection saying that the ACL2 Sim in the exact asked for FOUR ACL statements instead of THREE. Has anyone recently done this seen this in the CCNA 640-802? If so, what could the fourth statement be? I can’t seem to think of one that would match this ACL2 scenario. Thanks!
Dan,
I took mine on 9/14/13 and I had ACL 2 sim and was asked for only 3 statements.
I passed the ccna 947 score.
On this Sim I got 4 questions which I only answer 2 correctly and the other 2 the questions were hiding due to the size of the window screen and I could not make the window bigger to read them.
So, there is a bug on this sim which I made sure I put it as a “comment” on that question on the exam.
I got question 2, 7
One of the hidden question was the number 6 which I could barely read it but when I did the “show vtp status” command, the IP address did not show up on my screen due to the stupid bug, so be aware.
wang
There is a clip on youtube which shows how to download cracked version of VCE
@Richard,
OK, as you said I will study questions from the dumps -”lead2pass by spike”
Thank you.
what is the correct answer for the 7th question from this vtp sim, given above?
Is it is,
A – All VLANs except the default VLAN will be removed from all switches
OR
D – The VLANs Servers, Management, Production and no-where will be removed from existing switches.
just clarify this to me.
hi maice,
the correct answer should be D.
because the newly added switch SWCHX has a higher serial no. the answer in my exam is a bit
different. the correct answer is “all the switches now has vlan student, ? , ? vlan configurated.
sorry i cant remember exactly the vlan names, but the idea is all the switches will have only
the vlan configured in SWCHX and other vlans like server, management, production were deleted.
i took the exam on 14 Sep.
@ Anonymous,
ok
http://blog.acmeinfotek.in/2013/09/incorrect-questions-in-ciscoacme640.html
I hope in this above link are correct answers.
@vicky: thnx
whether these three are correct commands, can anyone suggest about this pls.. ?
(1) “sh mac address-table”. This will give which MAC is connected to which port.
(2) “sh ip device tracking interface gigabitEthernet “. This will give which IP is connectd to a port.
(3) “sh ip arp” will give you a IP to MAC table
I wanted to clarify about the 3rd command “sh ip arp”
the ios command sh mac-address-table is not working in the ccna exam simulator
you have to type sh mac address-table!
show arp will show you your Ethernet/ARPA/MAC addresses which are mapped to IP addresses for the hosts which have previously ARPed your router. They basically display the same info. The show arp will show you not only your IP-MAC, but other L3-MAC addresses, e.g. Appletalk. While show ip arp , will by definition show you only your IP-MAC bindings.
Hi. I have a question. For the VTP Sim, do you have to enable first before putting in the commands? Or do you just put in the commands? I noticed that in the examples that it has the # symbol before the commands. Please help
passed CCNA this morning (the old one) and can confirm as someone else stated that the show vtp status on the sim didn’t show the ‘configuration last updated by section’ as shown above and in real life!
everything else was there, not sure how I was supposed to get that information in another way?
hi worto03,
i passed CCNA last saturday. regarding the show vtp status command, i also cannot see the ip
address which update the switch vlan on the first time, but then i type in one more time, and
scroll the screen back up, amazingly, the ip address come out!
this may be a bug of the exam simulator.
also in the acl simulation, after completed everything i type the command copy running-config
startup-config to round things up. but when i check with the show startup-config command, i
cant see the outbound acl configured on interface fa0/0. but i can see still see it in running-config.
i copy it again but still the same!
