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.

thanks steve i got it
@jane
VTP = Vlan Trunking Protocol :)
welcome to the cisco world jane
thanks 9tut and xallax.. i’ve been following this blog for 3 days now.. planning to take ccna soon.. this site really helps!
@xallax : which dumps would u suggest and do u have source frm were i can get latest dumps ? if you have could mail me in this just4techz@yahoo.com
9tut.com has been an incredible help, although I just took my test today and failed. The questions have changed. I’ve studied everything and gone over 400 + questions and sims. I don’t know where I went wrong. Kendhe@gmail.com
Hello all, I have a question for you….
Is it possible that in a vtp client can have higher revision value than the rest of the members without affecting the rest of the domain? This is contrary to what we have learnt us that a client/server which has higher revision that enters a domain will update all the others with its own configuration. But I have found a strange question on the web that doesn’t agree with that. Do you have any idea??
@Bruno: The switch in the client mode with higher revision value will update all switches in the VTP domain. At least it works so in my test network. AFAIK some dumps have errors.
@Bruno
It must be an error. These guys who write this tutorial sometime do make mistake, not intentionally.
My advice is read from a different a writer or maybe a couple of them, and then go with the majority.
Pls can u provide me wit a link to download the latest ccna dumps 640-802

@ahmad: All tools for the exam are listed here: http://www.certprepare.com/forum/index.php?showtopic=1664
i’ve often see in dumps the possible trunking modes are
Auto
on
desirable
what are they???Plz any one expalin ths??
@ciscocraze
auto – it will wait for someone else to initiate trunking on that interface
on – it will always be in trunking mode on that interface
desirable – it will initiate trunking on that interface. if the device on the other side accepts trunking then it will become a trunking port. if the device on the other side does not accept trunking then it will continue to work in access mode.
how many cuestion is about VTP on CCNA EXAM ?
i would be attempting CCNA 642-802 this week can anybody answer me on latest dumps

@xallax
Please, bare with me. This might be a little lengthy. I have a couple of questions and scenarios regarding VTP. Thanks.
Q1 above.
The problem with Vlan having connectivity issue is due to incorrect revision numbers.
So basically, connectivity issues might be a switch failing to exchange valn information, failing to process valn information or failing to forward vlan information. (Not participating in the VTP management process)
What happens if two switches in a server mode with different revision numbers and different domain name fail to exchange vlan information.
Will this create a connectivity issue? Cos, basically once domain name is rectified, is then a matter of one switch over written the other.
So ideally, is it safe to say what causes connectivity issues is different domain name, different version number and different password on the switches.
What role exactly does different revision number plays in connectivity issues?
Lastly, when a switch in a client mode in a VTP management domain receives a summary advertisement with a revision number higher than its current revision number, the switch will issue an advertisement request for new Vlan information. (No connectivity Issue)
@koffy
different domain name and different passwords will not allow the switches to exchange VLAN information
the revision number dictates which switch will be the origin of the VTP updates that will flood the switched network.
as for “when a switch in a client mode in a VTP management domain receives a summary advertisement with a revision number higher than its current revision number”…
client gets the frame, reads it, sees a greater revision number, updates its vlan.dat, send the vtp update on other trunk links.
@xallax
Thank you.
@Xallax
is it update its database or replace the current with new database.
@francis
replaces it, you are correct, thank you
@xallax
my Exam on 31 october advice me please I Postponed it many times and I am very worried about it >>>>
@mouhammad
if you don’t feel you ca do perfect on switches, security, routing protocols, wireless, ipv6, subnetting, basic protocols and their usage, then you should postpone it because there;s no point in just throwing money away if you’re not properly prepared for the exam
@xallax
pass my CCNA 31-10-2011
sim:
VTP
EIGRP
ACL2
and the rest was mcq
Thanks for you and 9tut ;-) :-)
Q2 is stupid.
New technician already must know all stuff about VTP. :)
In the CCNA test I took today, there was a question about VTP showing two sites, one ws server and the other client, yet both with domain and revision in blank (nothing specified). There were five choices to pick; I was clueless, so I pick something around the term of debugging the VTP. Have anyone seen this question? How can you work around a VTP that doesn’t have the Domain or revision number at both sites?
@ Raul: If the domain name is NULL on all switches on a broadcast domain then they will not exchange VTP advertisements between them; i.e. VTP is not in action there.
In this case, as soon as you configure a VTP domain name on one of the VTP servers, it will propagate the VTP domain name to all other switches which have a NULL domain name.
Just for the record, at Q9, answer C is correct too.
Switches in CLIENT mode DO originate summary advertisements. This is how a switch with an identical domain name as that used on your network and a higher configuration revision number, can mess up your VLANs on the local network if added without resetting its revision number to 0.
Don’t take my word for it, check the CCNA course at section 4.2.3.3 (second paragraph, under “Summary Advertisements”) and also check this web page: http://ptgmedia.pearsoncmg.com/images/9781587201967/downloads/VTP-issues.pdf
Therefore, as far as I can tell answers B,C, and D are correct at Q9. Nonetheless, they only ask to pick 2, so it seems that the authors of this question screwed it up unintentionally.
pls where can i get the WAN encapsulation commands?
thanks a lot. will u please send me the latest ccna dump. email is—sukhjit.kandola@yahoo.com
thanks…

Hi 9Tut
This question seems to be based on the old catalyst OS is this still being tested on? The newer switches are they not all a type of IOS. So the equivalent today would be….
Swtich(config)#vtp mode server
Switch(config)#vlan 50
Switch(config)#int fa #/#
Switch(config-if)# switchport access vlan 50
very 9c, Exaud from Tz
