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?

show_vtp_status.jpg

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)

show_vtp_status_add_VLAN.jpg

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?

show_vtp_status_2.jpg

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)

VTP_mode_client.jpg

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.

    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

  4. sniffer
    September 16th, 2012

    @ 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

    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..

    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 ?

    @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 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…
    ..

  28. Agtrk
    January 6th, 2013

    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!

    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

  39. StudyMan
    February 20th, 2013

    @Marin Whoever has the highest revision (whether it is Server or Client) will update the VLAN info of the domain.

    Any Question of VTP is in the exam??

  44. Q6
    March 16th, 2013

    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.

  45. Roy
    March 18th, 2013

    @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.
