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
Other lab-sims on this site:
and the persosns who are having a problem in the command to get mac address in real simulation in paper just use command..#show mac….or use show ? u will get all commands related to that…..
I am new to CCNA. If I come accross a simulation question that says: ” Click on the appropriate device to solve this simulation/ question”; so where exactly can I click? On the Console Host or Router/ Switch? Pls I want someone to help me with this.
i pass with 960 marks access-list,vtp and EIGRP are still vallid. BE VERY CAREFUL with the access-list
QUN faya click on the console host to access the routers
I COMMAND U NOT TO WAIST time on the question u have answered correctly,click next because if u do not take care u time will be up because of the labs so hurry-up.I salute u all
For those who have taken the exam, can we use the “?” and “tab” key? Some say we cant and some say we can.
I found this:
http://www.facebook.com/notes/cisco-certifications/august-9th-2012-mythbusting-the-ccna-simulatrions-with-dennis-masters/10151088084627521
how can a switch knows all the mac addresses connected to its interfaces, if no traffic have been issued. because issuing show mac-address-table from this lab ; does not show u all the connected hosts.
Greg u need to check the mode u are in before the ? will work, try to type more than 3 words of the name of the command.Actually it works in the exams but study ur commands very very well
Alino first assign ip address to the user before u can see the mac address in the mac address-table
24/7 online help,there is more blessing in giving than in receiving
@ lillymy: u mean the one not in the Vlans? it can be Ok. but i think it has to ping to the broadcast also so that the switch learn all host’s mac addresses.
before it works attach the user to the switch to suite the port number and assign the ip address to it
Just sat the exam and did not pass.
A note on the VTP sim, with question, From which switch did Sw-Ac3 receive VLAN information ?
When you type in show VTP status, it DOES NOT PROVIDE “CONFIGURATION LAST MODIFIED BY <>.
thanks Lillymy, i been studying so much and been using the shortcut commands like “config t” not “config terminal” so its hard to break that now. The hard commands for me to remember are the ones for NAT, i end of using ?.
JohnnyK,
what mode where you in?
SW-AC3#
or
SW-AC3(config)
Excuse me if I type the command sh mac address-table I can not find the answer fa 0/8 as shown what is the solution
HI Guys,
can anyone tel how many questions are the in the VTP sim , is it 9 t or 5?
Thank you Lillymy! I now feel very confident to face the sims.
@dane
If you can’t find it using ‘sh mac-address-table’ or ‘sh mac address-table’, use ‘sh run’. I found it there.
This is very important simulation for exam. This was in my exam this month including EIGRP and Access-list 2. I passed (907/1000), not to be scared. Exam is not as difficult as you might think but time management is crucial. THANKS A LOT to 9tut.com
I passed CCNA with 981..Still the dumps are valid but should have a deep look at the ACL Sim because in that Sim u have to permit a host to access the http from the finance server n you have to block all other type of access to the finance server. And deny other hosts from accessing finance server and should permit core and all hosts to access public server
Hey guys,
Today i passed the exam 854…. the dumps are still valid… and the sim’s are vtp, ACL, Eigrp…… be care full with the simulations….. i got less marks because of simulation only….. wish u all a luck….. im happy… see u all soon…… thanks a lot guys….. keep posting the codes and new changes in this forum so that all new takers can learn a lot…. once again thank you all… :-)
Passed CCNA, labs were with CCNA VTP SIM Question and the other CCNA Access lists Sim 2 modified with added request which includes not only finance server, though the other one (with no more than three lines).
I’ve noticed a bug in PT for this simulation as I took my certification exam.
I’ve tried to view the MAC Table but I had no luck with the command show mac-address table.
After 5 minutes I have tried a shorter commmand #sh mac …and it worked. Be careful with this bug
VTP sim question 8.
how would you find the VLAN# associated with a given IP address?
question 8:
“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.”
how can you tell the source IP address 192.168.44.1 belongs to VLAN 44?
Great site guys, thanks for the help.. Passed with 940, had VTP, ACL2 and EIGRP sims.
Acme, Sekhar and Spike are 100% valid, also 6 years of hands on experience and packet tracer labs greatly helped to truly understand all the concepts. Learn the material guys, don’t just regurgitate the answers…
On 2 CCNP!! Peace!
@Anonymous – by default, we assume that a class C has a default mask /24. So 192.168.44.1, belongs to VLAN 44.
Regarding to the last question, I think the answer in 9 tut is not corret…..
A host, connected to SW-AC3, will have a default gateway that will be the IP of a subint of the Router, acoording to VLAN. For instance, if host belong to VLAN 33, his default gateway is 182.168.33.254.
9Tut, say that the default gateway will be 192.168.1.254… I think is wrong…. This is the default gateway of the switch, and also the hosts that are in VLAN 1…. But hosts in other VLAN will not have this Default Gateway.
Hey Guyz I have a paper a head on Monday March,4 2013.. Please pray for me i have built up really very strong concepts as an associate. I Read so many reviews about the exam LAB which always be VTP, EIGRP & ACL.
@Marin @Anonymous:
I guess for the Question 9. It was asked about the MAC address, if we count the default gateway for the VLAN44 (which is 192.168.44.254) or the switch default gateway both are on the same port so the MAC would be same.. Yes!! definitely the tweeks of answer should be different if and only if the IP address was concern.
Correct me if I am wrong and pray for me thanks.
Nice forum for CCNA exam takers God Bless you all.
“Aspire 2 Inspire b4 U Expire” ;)
there is no print button on this page @owner
thanks i found
Hi Guys, where can I get the CCNA dumps? I am taking the test tomorrow and would appreciate it if someone can send it to me: longyanf@hotmail.com
Congrats to all those that recently passed it.
Does anyone out there have Packet Tracer 6 or later? Please send to aaegh7@gmail.com. My version (V5) does not support iBGP…I’m preparing for CCIE.
Thanks in advance.
in question no.7, how can we assume that the revision no. on other switches is lower than SwX? It does only compare on Sw-ac3.
Hi, everyone! I passed my CCNA exam last week. Big thank 9tut! You cleared to me a few facts that really made me confused.
And, about questions:
VTP was exactly the same (5 questions: 1) Out of which port will the SW-AC3 forward frame with MAC… 2) Which ports operate as trunks? 3) From which switch did AC-SW3 received VLAN information? 4) Which switch is the root bridge for VLAN1? and 5) Out of which ports will be forwarded a frame with unknown MAC…)
ACL – permit web access from host C to the Finance Web Server; all other types of access to Finance Web Server must be denied; allow other traffic
EIGRP – change AS number and configure the IP address at the central router’s Fa0/1 (i am not sure about the interface number, sorry); hence, an IP address was missed!
I want donate to this great site, but it is impossible from my county… :(
Please, give a permission to all VISA cards in the world.:)
@jake: good question!
regarding question 9: i think the host will forward the packet to its default-gateway not the switch’s default-gateway.
And because only VLAN-R1 provides subnet for VLANs, the packet will be forwarded to the trunk port connected to the Router. In this case the port is Fa0/3 and we can find the MAC-add for this port!
hey any one need any help
@jake
Actually we can’t be sure in a real world situation without checking the other switches. however if you look at the answers the all they refer to changes to all switches. Therefore we assume that the revision number on all switches is equal.
Studying to take the 640-822 next week. I am confused on what simulations I should be studying just for the ICND1 portion??? Thank You!
Finally, I Passed CCNA today with 920/1000. Studied PrepKing 680q (it ‘s really very valid right now) , Brar and 9tut. There are some questions in PrepKing 680 absents in Brar, I think you should learn Brar then PrepKing.
All Labs were the same as 9tut: 5 VTP , Acl 2 (
+Deny host C -> Finance Web server eq 80,
+all others access to Finance Web Server from hosts and corelan should be blocked
+All hosts in the Core and local LAN should be able to access the Public Web Server
)
EIGRP AS 222 ,change IP , and the rest exactly same as 9tut.
Thanks 9tut , and all nice guys here ^^.
tell me this sim is correct ? coz i coudnt find the answer for show mac address-table command….there was not the answer among thos mac addresses?
Thank 9tut. I passed the test this morning with 933/1000, Sims are ACL, VTP and EIGRP. Strongly recommend all questions in this website and find some newest VCE here: http://www.examcollection.com/640-802.html (Sekhar or sth else …..). So happy with this result !
Good luck for all future candidates ;-)
@Nera: This is a simulation, in the real test the mac-addresses are full…
Today i passed my exam & i score 960/1000,
Thanks to 9 tut for sim practice, but there is bug in exam that they asked in VTP to
“From which switch did Sw-Ac3 receive VLAN information ?”
i give command “show vtp status” but there is no ip address from which it modified & also sw-ac3 is client, therefore i give approx ans which i see here bcoz there is no option for me to give ans, & also a bug is there is not working “show mac-address-table” command when i give shortcut of “show mac” then it show mac table
Sim is ACL2, Eigrp & VTP, paper is very easy, i complete my paper in 1 hrs. therefore don’t be hurry in exam bcoz once u go to next Q. u don’t come back, therefore understand the Q. & then give confirm ans.
ACL2 :
allow host B to financial web server to access web browser
other services are deny to lan, core & also host B
to other permit all
EIGRP :
Configuration same as Here only IP address & Router name different.
Thank to 9tut, god bless u, u doing nice work to helping us.
guys today my exam can i get some advice
Can some please email me the latest Dumps at mnmshafi@ymail.com
If you cant find the answer by typing show mac-address-table than use this comand show running-config. Thanks
thank 9tut. i passed exam yesterday. About my exam one eigrp and one access list which are in the 9tut but they modified.good luck…
No need of “show run” command instead of “show mac-address-table” when not working bcoz “show mac” shortcut command work, i used it in yesterday exam & it work.
Yesterday i clear my exam with 960/1000 marks in just 1 hrs, paper is vary easy.
Sim is VTP, EIGRP & ACL2
EIGRP & ACL sim also easy,
In EIGRP there is no passive-interface between R1 to R2, R3 or R4, therefore no need to remove it, only the passive-interface is in between R1 & ISP but we don’t need to remove it, the AS no. is 221 & other configuration is same as shown here, I right here Router name R1, R2, R3 & R4 only just for ur understanding bcoz there is router name & IP addresses are different, but configuration is same.
In ACL they said
Host B should be able to use a web browser(HTTP)to access the Finance Web Server
Other types of access from host B 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
But there is much bugs in VTP :
First i tell u which Q. comes in it,
Q.1 What interface did Sw-AC3 associate with source MAC address 0010.5a0c.ffba ?
Bug : There is “Show mac-address-table” command not working therefore i used shortcut of it “show mac” & then it show me mac address but there is Fa 0/12 interface associate with it.
Q.2 Which switch is the root bridge for VLAN 1?
Ans : Ans same as here
Q.3 From which switch did Sw-Ac3 receive VLAN information ?
Bug : I used “show vtp status” command, the mode of switch is client but there is no IP address shown from which it take VLAN information therefore i have no idea what can i do, therefore i give approx ans which i seen here, i don’t know it is right or wrong in there.
Q.4 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?
Ans : Here is vary big twist bcoz ans is same but they right there in different form, they say that All existing switches will have only students, admin, faculty VLANs. There is no option of “The VLANs Servers, Management, Production and no-where will be removed from existing switches”
Q.5 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)?
Ans : Same as here shown.
I think it help u guys, best of luck to all, i share it bcoz happiness is increase when it share.
When u also give exam then it share may that help anyone.
From bottom of my heart thank you vary much 9tut, u guys doing vary nice job to helping us, god may bless you…….
@Umit – Congrats on becoming certified.
Could you please elaborate on the MODIFIED part?
Thanks!
@Ketan, Congrats !!! & much appreciated on the details provided. I am very sure the soon to be certified folks would really be greatful to you.
