CCNA – VTP Questions
Here you will find answers to VTP Questions
If you are not sure about VTP, please read my VTP tutorial
Question 1
Refer to the exhibit. After SwitchB was added to the network, VLAN connectivity problems started to occur. What caused this problem?
A. Both switches are in server mode in the same domain.
B. The revision number of SwitchB was higher than the revision number of SwitchA.
C. SwitchA was not rebooted prior to adding SwitchB to the network.
D. V2-mode is not enabled.
E. VTP pruning is not activated, so the new paths in the network have not been recalculated.
Answer: B
Explanation
SwitchB has the same VTP Domain Name with SwitchA and it has a higher Configuration Revision number (7 > 1) so it will overwrite VLAN information of SwitchA. Because SwitchB is a new switch so its VLAN information is different from SwitchA -> VLAN connectivity problem occurs.
Question 2
A network administrator is explaining VTP configuration to a new technician. What should the network administrator tell the new technician about VTP configuration? (Choose three)
A. A switch in the VTP client mode cannot update its local VLAN database.
B. A trunk link must be configured between the switches to forward VTP updates.
C. A switch in the VTP server mode can update a switch in the VTP transparent mode.
D. A switch in the VTP transparent mode will forward updates that it receives to other switches.
E. A switch in the VTP server mode only updates switches in the VTP client mode that have a higher VTP revision number.
F. A switch in the VTP server mode will update switches in the VTP client mode regardless of the configured VTP domain membership.
Answer: A B D
Question 3
What are two benefits of using VTP in a switching environment? (Choose two)
A.It allows switches to read frame tags.
B. It allows ports to be assigned to VLANs automatically.
C. It maintains VLAN consistency across a switched network.
D. It allows frames from multiple VLANs to use a single interface.
E. It allows VLAN information to be automatically propagated throughout the switching environment.
Answer: C E
Question 4
What is the name of the VTP mode of operation that enables a switch to forward only VTP advertisements while still permitting the editing of local VLAN information?
A. server
B. client
C. tunnel
D.transparent
Answer: D
Question 5
Which VTP mode is capable of creating only local VLANs and does not synchronize with other switches in the VTP domain?
A. client
B. dynamic
C. server
D. static
E. transparent
Answer: E
Question 6
An administrator is unsuccessful in adding VLAN 50 to a switch. While troubleshooting the problem, the administrator views the output of the show vtp status command, which is displayed in the graphic. What commands must be issued on this switch to add VLAN 50 to the database? (Choose two)
A. Switch(config-if)# switchport access vlan 50
B. Switch(config)#vtp mode server
C. Switch(config)# config-revision 20
D. Switch(config)#vlan 50 name Tech
E. Switch(vlan)# vlan 50
F. Switch(vlan)# switchport trunk vlan 50
Answer: B E
Explanation
First we notice that the “VTP Operating Mode” of this switch is “Client”. In this mode we can’t add new VLAN so we must change to “Server” mode -> B is correct.
Now we can add a new VLAN, E is the correct configuration for adding a new VLAN.
Question 7
To configure the VLAN trunking protocol to communicate VLAN information between two switches, what two requirements must be met? (Choose two)
A. Each end of the trunk line must be set to IEEE 802.1E encapsulation.
B. The VTP management domain name of both switches must be set the same.
C. All ports on both the switches must be set as access ports.
D. One of the two switches must be configured as a VTP server.
E. A rollover cable is required to connect the two switches together.
F. A router must be used to forward VTP traffic between VLANs.
Answer: B D
Explanation
In Cisco switches there are two encapsulations: 802.1q and ISL so we can set two ends to ISL instead -> A is not correct.
The ports between two switches must be set to trunk ports so that they can exchange VLAN information through VTP -> C is not correct.
To connect two switches we can use cross-over cable or straight-through cable (because modern Cisco switches can “auto-sense”) but not rollover cable -> E is not correct.
To forward traffic in the same VLAN (between two or more switches) we can use switches only. If we want to forward VTP traffic between different VLANs we can use either a router or a Layer 3 switch -> F is not correct.
Two switches can only communicate when they are set to the same VTP domain name (and the same VTP password) -> B is correct.
One of the two switches must be set to VTP Server so that it can create VTP updates and advertise its VLAN information.
Question 8
Which statements describe two of the benefits of VLAN Trunking Protocol? (Choose two)
A. VTP allows routing between VLANs.
B. VTP allows a single switch port to carry information to more than one VLAN.
C. VTP allows physically redundant links while preventing switching loops.
D. VTP simplifies switch administration by allowing switches to automatically share VLAN configuration information.
E. VTP helps to limit configuration errors by keeping VLAN naming consistent across the VTP domain.
F. VTP enhances security by preventing unauthorized hosts from connecting to the VTP domain.
Answer: D E
Explanation
The main purposes of VTP are to simplify switch administration and limit VLAN configuration errors by allowing switches to automatically share VLAN configuration information. It doesn’t require the administrator to go to every switch to configure VLANs.
Maybe you will feel F is also a correct answer but it is not true because VTP only enhances security by preventing unauthorized switches (not hosts) from connecting to the VTP domain (by configuring a VTP domain name & VTP password). An unauthorized host can easily use the network cable of an authorized host to access the network.
Question 9
What are two results of entering the Switch(config)#vtp mode client command on a Catalyst switch? (Choose two)
A. The switch will ignore VTP summary advertisements.
B. The switch will forward VTP summary advertisements.
C. The switch will process VTP summary advertisements.
D. The switch will originate VTP summary advertisements.
E. The switch will create, modify and delete VLANs for the entire VTP domain.
Answer: B C
Question 10
Refer to the exhibit. The show vtp status command is executed at a switch that is generating the exhibited output. Which statement is true for this switch?
A. The switch forwards its VLAN database to other switches in the ICND VTP domain.
B. The configuration revision number increments each time the VLAN database is updated,
C. The switch forwards VTP updates that are sent by other switches in the ICND domain,
D. The VLAN database is updated when VTP information is received from other switches.
Answer: C
Explanation
In Transparent mode switch just forwards update sent by other switches without reading it. It doesn’t update its VLAN database so the Configuration Revision doesn’t increase.
Question 11
Refer to the exhibit, The VLAN configuration of S1 is not being in this VTP enabled environment. The VTP and uplink port configurations for each switch are displayed. Which two command sets, if issued, resolve this failure and allow VTP to operate as expected? (choose two)
A. S2(config)#vtp mode transparent
B. S1(config)#vtp mode client
C. S2(config)#interface f0/24
S2(config-if)#switchport mode access
S2(config-if)#end
D. S2(config)#vtp mode client
E. S1(config)#interface f0/24
S1(config-if)#switchport mode trunk
S1(config-if)#end
Answer: B E
Explanation
First from the output of S1, we learn that it is running under “vtp transparent mode”. In this mode, S1 still receives VTP updates but not learns them. Also in this mode, no trunking is created -> It should be in client or server mode but S2 is already in server mode -> S1 should be in client mode -> B is correct.
Also, VTP updates are only sent on trunk links so the link between S1 and S2 must be set as trunk -> port f0/24 on S1 should be configured as trunked port -> E is correct.
@xallax
I thought ADF are the correct answers for smart68′s q1. Thank you for clarifying. AEF it is then. :)
guys in q10
y can’t we put s1 also in server mode, VTP should still work normally……right?
plz correct me if m wrong…………..
ohh sry i mean in q11
@ Ankushk it is ideal to have one server on the network so that it can update and advertise it vlan data base to other switches. if we have two servers the server with the higher configuration revision number will propagate it data base the other hence causing network instability. hope this help
Just cleared my exam with a perfect perfomance (1000/1000)…..GRATITUDES: First and foremost to the almighty God for everythng he has been since i started preparing for this exam abt a year ago! the Todd lamlle (6th edition), this book gave me the foundation i needed and i consider myself one of the fastest subnetting geek thanks to Todd’s chapter on subnetting…then seriously, who wud forget this guy (9tut) thanks alot man,i finished my exam 40 minutes before time thanks to the speed you gave me in simulations…examcollection, thanks alot guys i ddint see any qn that i hadnt met in the dumps before, then the CBT nuggets videos….they cleared (enhanced) all of the concepts i have learned from all of the materials i have already mentioned! thank you all so much…..i will DONATE when i get my credit card! keep the good work going 9tut
ABOUT MY EXAM:
I had total of 50 questions….
Had three simulations….ACL2, same as here at 9tut but modified as the third table of modifications above and i was dealing with host B plus different IP addresses, EIGRP almost the same as here, had to change the AS in router Home 2 from somethng 21 to 221 and add the appropriate networks also i had to delete and add some networks from router Home 1 (central router) and finaly the VTP…same as here just different question to follow the same procedures in resolving
NB: i ddnt see anythng that i had not come across before
for any other enquiries find me at ropamson@gmail.com …..best of luck for everybody working on CCNA
is a B the answer? Because the link is in acecss mode and is currently assigned to the Admin VLAN. You can see from the exhibit that Port Fa0/1 belong to VLAN 20, the Admin VLAN. That’s why Admin VLAN has no problem communicating across this acecss link. You need to make it a trunk before other VLANs’ frames can travel on it.Cheers
Do these people that ask for dumps actually get them?
Is the SDM used in the CCNA exam?
@9tut- in q6 option b should be :- switch(config)#vtp mode server
CJ good quetion 9tut is the SDM used in the exams?
@cj, CCNA Champion: No, SDM is not used in CCNA exam.
@riOt: Yes, I updated that question. Thanks for your detection.
hello All, need latest CCNA Dumps…… please Mail Me 360.faraz@gmail.com
thanks in advance….
can any 1 provide me the latest dumps anirban.mpsez@gmail.com
hi guys, i’m still a bit confused on question 6…..I think it should be A and not E. (as long as the switch has already been made a server). you can configure VLAN 50 like this as long as VLAN 50 is on the interface in the interface sub command. Why is “E” stated as the correct answer?
@Anybody
@9tut
Whether can we use tab key to fill the full cmds??
Also can we use shortcut cmds in exam like we use in gns3 or packet tracer??
eg:sh run, sh ip int br, sh ip rout…
thanks.
@warren
before u assign the vlan to the switchport how can u access the switchport.the concept is add vlan 50 to the database..so at first we saw the mode in client mode isn’t possible so change into server or transparent then add the vlan 50..
TY 9tut.
Today I have passed the CCNA. (860/825)
50 questions 3 labs (VTP, EIGRP, ACL). 35 from 9tut.
Also thanks a lot Brar and Sekhar (still valid from examcollection)
Ty again 9tut
from here none
Q.11
What do you mean by the statement, “Also in this mode, no trunking is created ” (from explanation section)?
Set the mode of a switch to transparent and tried to make a port as trunk port and could do it successfully…. Is this what the above statement contradicting?
Can some one resolve the confusion ?
1 new qn from VTP..
how vtp advertisements are sent across network
options -mc,bc,uc and anycast
answer is multicast
what vlans are used for normal operations?->new qn
Answer is 2-1005
@cowboy -Vlan 1, 1002,1003,1004,1005 are default vlan . Normal vlan are used from 2-1001 and extended range 1006-4095
@ DanielL i cant agree with you more. The cowboy had gotten it wrong.
@suresh
E. Switch(vlan)# vlan 50 not a correct command syntax.
It should be : Switch(config)#vlan 50
@Warren
A is a correct.
hi frinds i have a Q> Suppose there are 2 switches and everything is working fine. Server has revision no 2 and few vlans. while client has revision no. 7 with some other vlans configured. What will happen? server will wipe clients vlans(though its revision no is smaller), or client will overwrite server because it has higher revision no.
pls help .
thanx
Hey Anonymous read this: anwer and experimental in there:

HI GUYS iam planning ccna exam next week. kindly ccna 640-802 dumps and lab sim send to my email id : p.immanuel@ymail.com
thanks
Hey Friends in Q2 the option A is incorrect according to me …bec in client mode the switch can update its database……….i read the tutorials too and it also conveyed it…
..
Q2 For A : Hi Ankit .I think that switch in client mode doesnt create any own database so it doesnt have a local database . Just so It has a database but this database is learned information from server. Not local or own database.
I’m not sure if there is a guy (or most likely an attractive babe) going out and giving out the latest dumps, if you exist, will you please email me the “latest” dumps to frankyestrada12@gmail.com. I promise I am studying really hard, but I just cant afford to fail my upcoming exam on the Jan 28th. My current employer has given me an deadline until the end of January 2013 to get Cisco certify. (a one month notice). This will be my only opportunity to get into networking from desktop support. I have been studying networking in the past, but Cisco networking is on a whole different level. I would really appreciate any help or suggestions! Thank you!
@9tut, Q6 from this page needs to also be corrected in the flash quiz 1. Correct option in the quiz indicate Switch(vlan)#vtp server but it should actually be Switch(config)#vtp mode server.
@xallax or any one who is master in networking,
hello friends can anyone tell me the alternate command for sh mac-address-table because this commands sometimes does not work in ccna exam…..rock3400@gmail.com
@rick: Please use the “show mac address-table” command instead (without first “-”).
@Grendel: Yes, thanks for your detection. I updated it!
guys which of following is a characteristic of full-duplex communication?
A it is CSMA/CD network
B it is CSMA/CA network
C it is point to point only
D hub communication is done via full duplex
i think answer is B,any suggestion and views here?
If anyone has the latest lab sims, please email them to pmt44@live.com. I am taking CCNA exam next week. Thank you in advance..:)

ok, I believe I misread Q6 and thought there was an interface that needed to be added too…. you right 9tut… if no int needs to be added to the vlan then E is the correct answer.
Can you tell me, if a VTP SW Server can learn from a VTP SW client?
Note that, the revision number of VTP Client is greater than revision number of VTP server
@Marin Whoever has the highest revision (whether it is Server or Client) will update the VLAN info of the domain.
I need assistance for this vtp question -from the usual diagram-; Out of which port on a Sw-Ac3 would a frame containing an IP packet with destination address that is not on a local LAN be forwarded?
Passed CCNA, question 1 modified from here, comparing 2 switches, one server, one client, both without VTP Domain names, confusing answers.
@ jah rastafarai
i have the same ques in the exam . that ques is from the new update question from the pre membership from 9 tut
Any Question of VTP is in the exam??
Isn’t correct answer in Q6 – A and B ??, because (vlan)# is not a valid configuration mode. And (config-if)#switchport mode access vlan 50, will automatically create vlan that is not active.
@Q6
Well, there are 3 correct answers for this question: A, B and E :) But…
“SWITCH(vlan)#” IS a CORRECT config mode. You enter this mode by “vlan database” command from privileged mode. However, this command is being DEPRECIATED (you can’t even see it in available commands by entering “?” from privilege mode).
Nevertheless, I would choose A instead of E. According to Cisco, it is RECOMMENDED to configure VLANs from config mode.
yes the explanation is right
any ques from this???
None but similar to VTP sim
For Q6) Two ways of configuring vlans
switch# configure terminal
switch(config)# vlan 5
switch(config-vlan)# name ENG
switch# vlan database
switch(vlan)# vlan 5 name ENG
switch(vlan)# apply
switch(vlan)# exit
9 TUT i cant say Thank you enough. Did my exam today..just revised using your materials and nailed it with 881. Am now starting CCNP… from tomorrow.And anyone going to do the exam, just read the questions twice, even if they seem easy. It worked for me.
God bless
