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

Quoting Rahmat:
“@show vtp status
I took exam yesterday .. Show vtp status was not show ip address from VTP server.,but i tried this command several times ..alhamdulillah I have Ip address from VTP server”
This happened to me today. The “Configuration last modified line” was missing. Any explanation on how to get information about the Server Switch?
@Anonymous
If its was missing, means switch was in vtp server mode. When you issue this command, check first which mode is configured on a switch. If its cliend, look for cdp neighbour , but if it’s server – it’s modified locally, means switch did it by itself
hi,please somebody can tell what was tha task in ACL when he was writing his ccna?
@9tut, or anyone who alredy did the exam and face this very same lab.
Regarding 1st. question on this lab. I have tried many times to find what interface the MAC 0010.5a0c.ffba belongs to using: show mac……, just does not work. But now I realized that using: show run at the end it shows the MAC associated with fa0/8 and statically assigned, which happens to be the right answer.
Question: In the exam is it the same, I mean if show mac….. does not work, if I use show run, is it the same than here?. I could see the MAC statically assigned to certain interface?
Thanks in advance for your hlep!.
Funny thing is that: show mac-address-table static does not display anything either!.
Hi All, I just did the exam today with 973/1000 score, sim are ACL2, EIGRP & VTP, thanks to 9tut.
@Cesar, you can use show mac address-table or you can use “?” to check what is the valid command in the exam.
Alhamulillah!!! Passed the exam today with 960,thanx to almighty Allah, 9tut and exam collection. No need to get scared guys study SEKHER dumps and 9tut its too enough to pass the exam easily. Today had eigrp,acl,vtp simulations as same as in 9tut.
Wish u the best !!!
Helo 9tut. Passed my Exam 640-802 last Week whit 841/1000. Thank you very much for your excellent Work on this Site. Had the SIMS VTP, ACL2 and EIGRP. Did the Exam in Europe. I study off course whit 9tut and Examcollection *Jericho and SEKHER*. Both are still valid and the best for CCNA. Again Thank you very much 9tut, you Guys ROCK !
Passed CCNA today. Thank you very much 9TUT and exam collection. SIMS were VTP,ACL2 and EIGRP. Just like the same SIMS in 9TUT, nothing much different.
IMPORTANT
I have seen posts in 9TUT saying #show mac-address table command doesnt work in the exam.
Yeah that happened to me too. But I tried different versions of the command and finally got it working.
For me #show mac command worked.
Good luck guyss!!
Guys were the answers for the VTP question exactly the same as the dumps or different? Same with the eigrp question. When I took the exam yesterday the ip addresses were different for eigrp.
Please respond guys. thanks.
@Random
When you study at 9TUT don’t rely too much on IP addresses and exact answers. Get the concept.
In the exam IP addresses and answers for VTP can be different.
Thanks Warner…Have you experienced this?
@Mike
Thank you for the quick response. It was set to Client like it should have been. I am starting to think it was an simulator issue now. I tried many ways to get the information needed to get the correct answer, but without that line, it is impossible.
@Random
Like Warner said, if you understand the concept, you will do just fine. I drilled on the labs provided by this website and using Packet Tracer for two weeks. I did the labs without any worry!
@Anonymous
What IP address did you see, or it was all 0.0.0.0? Just wondering
Hi Anonymous,
I bassically just used this site, because the dumps that i saw were the same question that we found here.
thank you
@Mike
I saw nothing. The bottom line of the VTP Status was completely missing. The bottom line that I saw was the MD5 Digest line.
Had an exam scored 875. This lab was in. building1 was as server and you have to configure building2 as client mode. and use last usable ip address.
Could somebody please send latest dumps for CCNA and another question is are there only three labs access list, eigrp and switch

Q8. I took the exam today. “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)
The “Mac Addresses” were replaced with “ip addresses”. I could not figure that out. Any ideas anyone?
@9tut Please explain what Eugene said The “Mac Addresses” were replaced with “ip addresses”. In the frame, ip addresses??????????
@Mike
Yes. I tried everything I could including the space bar multiple times to get the last line to show to no avail. I am currently reporting the error to Cisco and Pearson. I will keep you all posted.
Another thing I just now remembered, they changed the wording of the Configuration Revision answers. I would watch for that, but for those who follow the advice of a lot of people who have commented before, the wording should not be an issue if you understand the concept!
@Anonymous
It’s really odd what is happened with you on exam. Must be a sim bugs.

Need Latest dumps. Taking exam on 18 Oct. Please send me to xpress.013@gmail.com
Need Shekhar dumps. Taking exam on 18 Oct. Please send me to xpress.013@gmail.com
Yesterday I did my CCNA, and I passed with 889/1000
We have the same exam content as Albert’s.
I recommend to review 9tut at least 2 rounds so that you’ll get score higher than mine, because I only review it at 1 round.
Thanks to God and to 9tut and to the profs of the academy
@Random
Yes I experienced it. For example the answer to the 1st question in this VTP sim was different in the exam. As i can remember answer was Fa0/12 not Fa0/8. So you shouldn’t memorize answers in 9tut.
@Rics
What are the sims? Any changes? specially EIGRP?
please tell us if there are changement in the sims(access-list or vtp)?
Q8: Out of which ports will a frame be forwarded that has source ip address __.__.__.__and destination ip address__.__.__.__? (Choose three)
A – Fa0/8
B – Fa0/3
C – Fa0/1
D – Fa0/12
Assuming the question is in this format and they just slot in the source and destination ip addresses. How will you figure out the answer?
Please, someone should reply this as quickly as possible..Thanks
@Zee. I did have this on my Test and could not answer. I have tried to figure it out ever since.
Anyone?
just now took CCNA exam 933/1000 great experience….simulations from 9tut …and sekar dump enough..thanks to 9tut once again
ALLIHAMDULILAhi,i wrote the ccna exam today 12/10/2012.I am certified.
The simulations that came out are Eigrp,ACL,VTP. but the questions are changed from what is here on 9tut.com.
E.g in the ACL,you have to write an ACL TO permit host c to the finance section via http and deny all other host and core.Also you have to deny host c any other access to the finance department apart from via http.Also you need to write ACL to permit core and LAN to the public web server.Also the dumbs is still valid but there are alot of questions that have been changed.
Best of luck in your exams
@ 9tut abd others
u have been ignoring this commment for the past days pls comment.
Out of which ports will a frame be forwarded that has source ip address __.__.__.__and destination ip address__.__.__.__? (Choose three
@wantono
I’m just thinking how you can do it with a switch :) answer NO how, it is no such a question. Switch layer 2 devise, can make forwarding desition only by using MAC addresses. And specially it is asking about three ports, no way to find out. Switch can flood the frame, but only to get an NAC address if it doent know it.
@ mike
this question was ask on my exam and i can’t answer it so and some other guys have ask this question which means they have faced such questions .
@wantono
Ok, let’s make it simple. They give you two ip addresses, right? So you have a source and destination. You can get information from source ip address on which VLAN it is. That’s fine. Then you are checking which ports belong to this VLAN. But here you are done. If destination ip in the same VLAN, only one port will be outgoing( switch getting frame (inbound) checking MAC table, sending it(outbound). If it is doesnt know MAC address, flood to all trunk ports and to ports in the same VLAN. If its different VLAN, from our topology, only two ports will be outgoing(getting frame- inbound), checking MAC table, sent it to router interface( outgoing), then router send it back to switch( inbound), switch check destination MAC, send it to appropriate port( outbound) This question doesnt make sense. You need to know MAC addresses to answer for this question, not ip.
@9tut and Mike
Out of which ports will a frame be forwarded that has source ip address __.__.__.__and destination ip address__.__.__.__? (Choose three)
How can I answer this question if it comes to my exam??? Any idea? please…
@Arif
Read above
Can we just study the free sims on the site or do we have to sign up to get real sims please let me know?
@mike
Please can you help me to resolve this question: 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?
Hi herman,
You should check the default-gateway configured on the switch. Then use show cdp neighbor detail and look for that IP Address. As stated above, that should be a router. If you found that IP address, look what interface it is connected to. E.g fa0/3. Then just use show mac-address-table command and look for port fa0/3. The mac-address in-line with that port should be the destination mac-address.
Hope that helps.
@herman
Default-gateway, in our topology, can be only a router, no need to check default-gateway on a switch, it will not help. Check “show cdp neighbour” which port switch is using for connection with router( in local interfaces), then get MAC address of that interface by issue “show mac” . Switch learned this MAC address from router physical interface. All router sub interfaces will have the same MAC address as physical.
ok thanks mike
@ABC i m not getting of your point please explain ???? Thanks
question on the adding switchX part. From the vtp status on the pkt tracer sim the md5 hash of the passwords doesn’t match so switchX wouldn’t update to others. Do the md5 hashes match on the real exam sim?
@J
I did a test based on your comment, even though the MD5 digest are not the same, they can have similar password like on the packet tracer.
If you will check the password, both have a password of home-office.
