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.
Shouldn’t question 10 be the answer C?
thanks
I’ve checked in Packet tracer – revision number stayed 0, when I changed local vlans and on server SW.
Correct answer – C.
dear 9tut i think also that the correct answer is c
Yes, the answer should be C. I updated it, thanks for your detection!
@9tut,
Thank you for the good stuff.could you kindly send me the latest CCNA dumps:mkisochi@yahoo.com
Dear 9tut.com,
I have simulated the environment of the question #1 (I added to the same VTP domain another switch with the same VTP domain name and password but with a higher revision number) and it looks like that the answer “B” is not the correct one. It’s weird because, at the same time, the other answers are wrong.
Could you help me with a more detailed explanation or could you try to simulate this scenario not in Packet Tracer but in a real live environment please?
@LatinDancer: Is your link between two switches trunk link? because VTP needs to be run on trunk link. You can check if the link between 2 switches is trunk link with the “show int trunk” command.
@9tut
Yes it… I created a well-working VTP domain between 3 switches with a router (route-on-a-stick like the configuration visible at this link:”http://www.orbit-computer-solutions.com/images/onstick.jpg” with 9 VLANs: 10, 20, 30, 99 which is the Management VLAN, plus the default ones: 1, 1002, 1003, 1004, and 1005).
The trunking protocol used was 802.1q and the revision number in the VTP domain was “9″.
Then, once everything was completed and well working, I have:
1. Created a new switch Cisco 2960
2. Setup the same VTP domain name and VTP domain password on it
3. Setup its port (the one used for the physical connection to one of the switches belonging to the existing VTP domain already configured (let’s say a switch called “SW1″ – like the one in the figure from the link mentioned above)) using the following commands:
“Switch(config-if)# switchport mode trunk”
and then
“Switch(config-if)# switchport trunk native vlan 99″
4. I did messy around the new switch by creating 7 or 8 fake VLANs (along with the correct Management VLAN with the number 99)…. obtaining, afterwards, a switch with a configuration number of “16″
5. Configured the port on the switch “SW1″ in trunk mode (same 2 commands as mentioned above)
6. Established the physical connection using a cross-over ethernet cable between the new messied switch (just configured) and the switch “SW1″
Then the configuration revision number in the new switch changed from “16″ to “9″. The fake VLANs went away and no network connections have been experiencing between the hosts belonging to the different VLANs.
NOTES:
#1: Before connecting the new switch to the existing VTP domain, I have connected a server to it and, afterwards, the connection between the hosts in other VLANs and this server behind the new switch (which belongs to one of the existing VLANs) was OK
#2: The new switch added to the existing VTP domain was configure in “VTP Server” mode
#3: The switch SW1 was configured in “VTP Server” mode already before connecting the new switch itself to it
Sorry for the long description!!!!
Today i made the exame and Pass with 920. The exame came from Ti 640-802 v218_New Question and Lab 14. Just a two questions were new and the simulations are the same ACL2 VTP and EIGRP. the first question was asking the ipv6 multicast address to all routers (FExx::1,FExx::2,FExx::3,FExx::4) while “xx” i do not remember what they was.
the second question was easy and it was two connected switches and no vtp connection between them, the first switch was vtp transparent and it’s port which connected this switch to the another switch was access port, the question asked you to solve the connection, i selected the two commands which make the swtich client (there was not a choice to make it server) and the other choice make the accessport to trunk mode
Finally, I am glad and soooooooo thaaaaaaaaaaanks to 9tut.com, special geating and u deserve moooooooooooooooooore.
can anyone give me the latest dumps link plz… my paper will be on next sunday(7th aug)
Dear 9tut,can u email me latest dumps at vpatel1788@yahoo.com
I have exam next week.
It would be a great help.
Thank You
question 6
Switch(config) vtp mode server
Switch(config) vlan 50
not Switch(vlan) vtp server
Switch(vlan) valn 50
Dear 9tut,
can u please email me latest dumps at shom.entc21@gmail.com
My exam is day after tomorrow. It would be of great help.
Thanks in advance.
Which 2 commands can be used to verify a trunk link configration status on a given cisco switch?
a) show interfaces interface trunk
b)show interfaces interface switchport
c)show ip interface brief
d)show interface vlan
What would be the appropreate ans. plz tell me………
Hie Shweta
i think a AND c are correct , not sure i there is no typo error on your question
@shweta
I think the answer is a and b.
Hello,
can anyone tell me that, these questions just answing or need configureation too, in the Routers?
AbdulAhmad.barakzi@yahoo.com
@ shwera arora . la bonne reponse a ta question est a et b
@shweta arora show interfaces trunk will verify trunk links on a switch. Show running-config should also show trunk links as well. I think there are typos in your answers and they make it confusing.
Question 6
Switch>enable
Switch#vlan database
% Warning: It is recommended to configure VLAN from config mode,
as VLAN database mode is being deprecated. Please consult user
documentation for configuring VTP/VLAN in config mode.
Switch(vlan)#vtp server
Device mode already VTP SERVER.
Switch(vlan)#vtp domain cisco
Changing VTP domain name from NULL to cisco
;)
To @9tut: Correct explanation to Q7, please. “To connect two switches we can use straight-through cable but not rollover cable -> E is not correct.”
Suppose you mean: “…we can use cross-over cable but not rollover cable…”
@DimS: I meant we can use straight-through cable in modern Cisco switches because they can detect automatically. I updated the explanation to make it a bit clearer. Thanks for your detection!
Hi all, i saw that the Exam questions was changed 30% can somebody tell me about the Exam or that the exam was changed? or can tell me list of the Simulations or how many simulation are in the exam?? i wana write my exam after one week, Plz help me i am highly appreciated you all.
CCNA Exam question asked: What happen if 2 switches is connected trough trunk link operational, but they don´t have domain name ?
Help, please!!!
@9tut: You are right but on an exam it may be critical. )))
@Claudio from Chile: Is it the full question?
@Dim
Show Q1 similar: show vtp status, but one switch between A y B and both don´t have name domain (a y B)
How do i can answer?
question 6 answer b
Switch(config)#vtp mode server
Setting device to VTP SERVER mode.
@arikaz
that only sets the switch as vtp server, it doesn’t create VLAN50. you need the second command too
xallax you are completely correct about that….. I was just showing the correct syntax for the command:
correct: Switch(config)#vtp mode server
not correct: Switch(vlan)# vtp server
it’s under the vlan configuration mode
switch> en
switch# vlan data
switch(vlan)# vtp server
it’s similar to
switch> en
switch# conf t
switch(config)# vtp mode server
@Claudio : AFAIK, if we don’t set vtp domain name on switches A & B then vtp domain name is ‘undef’. It means: switches will not exchange vlan info. So the answer must be something alike: “VTP domain name must be configured and must be same on both switches.” You can test this Q in the Packet Tracer, moreover I advise to test it in case of misundestanding.
@DimS
Thanks DimS.
Can exist several switches in a server mode in a only vtp domain?
In accordance your previous answer if a swtich are in a same vtp domain in any mode (transparent, client, server) with higher revision number othe switches overwritte information vtp..
@claudio
yes, there can be multiple switches in server mode in the same vtp domain.
@Claudio:
1. You can have multiple switches in server mode in VTP domain.
2. If you add switch in transparent mode in VTP domain: its rev. number is locally significant and will not affect for other switches. If you add switch in server mode with rev. number higher – VLAN info will be overwritten.If you add switch in VTP domain in client mode with rev. number higher – VLAN info from this switch will overwrite VLAN info on other switches.
Thanks for your contributions. Could you please help me the latest Dums. I am taking my exams Allah ‘will this month.
sani cmc Trivandrum India.
9tut, could you send me the latest Dumps to jamaicanvibes@hotmail.com , I will be taking the exam on September 15th.
Thanks in advance.
Q2.
“A switch in the VTP client mode cannot update its local VLAN database”, but if a switch in server mode have a higher revision number overwritte information Vlan (Question LabSim).
I don´t understand it . Clear me please!!!
@claudio
client = i can’t do it on my own (can’t update VLAN database – flash:vlan.dat), i let others teach me (receive VTP updates from switches running in server mode)
server = i am so smart that i teach others if my information is newer than theirs (higher revision number)
transparent = i study on my own and don’t care about what others, i can pass the information from one another, but i keep my own studies (has an independent VLAN database, does not process VTP frames, forwards VTP frames out interfaces in trunk mode)
@Kareem
It´s right? dou you need to permit encapsulation into trunk?
S#config terminal
S(config)#vtp mode client
S#copy running-config startup-config
S(config)#interface fa0/0
S(config-if)#no switchport mode access
S(config-if)#switchport mode trunk
@claudio
no need for “no switchport mode access”, the “switchport mode trunk” command will overwrite the old mode.
the interfaces used to connect switches should be set to trunk on at least one end because they don’t autonegotiate the trunk mode if both (or all on that node) switches are set to autonegotiate
can someone plz send me latest dumps at e_cherisme@yahoo.fr
Hi, Appreciate if someone could send me the latest dumps at treepanel.ken@hotmail.com , i plan to take the exams at the end of sep.
Thanks.
@xallax.
VTP tutorial says: “By default, a switch operates in VTP Server mode with a NULL (blank) domain name with no password configured (the password field is not listed in the output)”
What situation does network have or don´t have name domain?
@claudio
it will not send or process VTP updates unless a VTP domain name has been configured
@xallax
If VTP mode has a NULL (blank) domain name, isn´t have domain name?
@claudio
NULL = 0 = nothing
yes, if VTP domain name is NULL that means the switch does not have a domain name configured.
@xallax.
VTP tutorial says: “By default, a switch operates in VTP Server mode with a NULL (blank) domain name with no password configured (the password field is not listed in the output)”
Clear please!!!
@claudio
ok, let’s “translate”
by default = new switch with no configuration
switch operates in VTP Server mode
a NULL (blank) domain name = it has NO domain name configured
no password configured = it has NO password set
even though it operates in server mode, the switch will not process VTP frames because there will be a domain name mismatch.
@ anyone can u send me the latest CCNA actual exam?
please send it to sab3001@hotmail.com
Appreciate anyone who will share it. Thanks!
