VTP Questions

May 1st, 2015 in SWITCH 300-115 Go to comments

Question 1

Explanation

VTP updates can only be forwarded on trunk links.

Question 2

Explanation

VTP version 1 and version 2 support VLANs 1 to 1000 only. Extended-range VLANs are supported only in VTP version 3. If converting from VTP version 3 to VTP version 2, VLANs in the range 1006 to 4094 are removed from VTP control.

Reference: http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/ios/12-2SX/configuration/guide/book/vtp.html

Question 3

Explanation

VTP Pruning makes more efficient use of trunk bandwidth by forwarding broadcast and unknown unicast frames on a VLAN only if the switch on the receiving end of the trunk has ports in that VLAN. In the below example, Server switch doesn’t send broadcast frame to Sw2 because Sw2 doesn’t have ports in VLAN 10.

Question 4

Explanation

Switch C can receive VLAN information from Switch A so Switch B can forward it to Switch C without updating its VLAN database -> Switch B is in VTP transparent mode.

Question 5

Explanation

VTP updates can only be forwarded on trunk links.

Question 6

Explanation

VTP version 1 and version 2 support VLANs 1 to 1000 only. Extended-range VLANs are supported only in VTP version 3. If converting from VTP version 3 to VTP version 2, VLANs in the range 1006 to 4094 are removed from VTP control.

Question 7

Explanation

VTP Pruning makes more efficient use of trunk bandwidth by forwarding broadcast and unknown unicast frames on a VLAN only if the switch on the receiving end of the trunk has ports in that VLAN

Question 8

Explanation

VTP version 1 and version 2 support VLANs 1 to 1000 only. Extended-range VLANs are supported only in VTP version 3. If converting from VTP version 3 to VTP version 2, VLANs in the range 1006 to 4094 are removed from VTP control.

Question 9

Explanation

If a VTP client or server with a null domain receives a VTP message with the domain populated, it will assume the domain of the received message and add applicable VLANs to its database.

Question 10

Explanation

VTP version 1 and version 2 support VLANs 1 to 1000 only. Extended-range VLANs are supported only in VTP version 3. If converting from VTP version 3 to VTP version 2, VLANs in the range 1006 to 4094 are removed from VTP control.

    Q10
    All your comments are true but the que asking about that particular switch not the switches outside that switch
    yes the switches outside that switch can use VTP v3 ad do the configs but the particular switch can not
    so the answer is D

    The answer to question 10 is transparent mode. In VTP versions 1 or 2 this is the only mode that allows extended vlans to be configured.

    Q.10 Answer A “Transparent”
    VTP version 1 and VTP version 2 do not propagate configuration information for extended-range VLANs (VLAN numbers 1006 to 4094). You must configure extended-range VLANs manually on each network device.

    To me this on of o “trick” questions from Cisco, I assume that: before you consider that switch needs to be in Transparent mode you need to realize that VTP version that supports extended vlans is version 3, therefore in my mind correct answer is D: Extended VLANs are only supported in version 3 and not in versions 1 or 2.

    This explanation has been gotten from the CISCO Document. “In VTP version 1 and 2, a switch must be in VTP transparent mode when you create extended-range VLANs. If VTP mode is server or client, an error message is generated, and the extended-range VLAN is rejected. VTP version 3 supports extended VLANs in server and transparent modes.” So correct answer is for the Q10 is “A” i.e. transparent mode.
    Because the question ask which VTP mode, not to version.

  11. Question 8
    July 25th, 2016

    Am I missing something? The explanation says…

    VTP version 1 and version 2 support VLANs 1 to 1000 only. Extended-range VLANs are supported only in VTP version 3. If converting from VTP version 3 to VTP version 2, VLANs in the range 1006 to 4094 are removed from VTP control.

    1 to 1000 = 1000 right? How is the answer 1001? Zero is not included

    No believe it should State VTP version 1 and version 2 support VLANs 1 to 1001 only.

  13. Bullet.Speed

    Answer for Q10 should be 1000. According to Q&A pdf file answer is 1001. Can someone please confirm?

    hi all

    Q.8

    VTP v2 supports range 1-1001 and not range 1-1000.
    Therefore, there are 1001 VLANs from 1-1001, both included

    Some Cisco docs state that the supported vl range is only 1-1000, but that leaves out VLAN 1001. And VLAN 1001 is neither a reserved VLAN nor an extended-range VLAN.

    Tested on (C3550-IPBASE-M), Version 12.2(44)SE6

    Q10 corresct answer is A

    In VTP versions 1 and 2, the switch must be in VTP transparent mode when you create extended-range VLANs. VTP version 3 also supports creating extended-range VLANs in client or server mode

    for question 10, in actualtest.com says that the correct answer is “Transparent” can anyone confirm this?

  20. brcdhacksaw

    I sent support an email to weigh in on Q10, transparent seems to be the answer, but wonder what Cisco testing peeps say..

  21. brcdhacksaw
    September 29th, 2016

    support dept of the site confirmed that transparent is answer…
    according to cisco docs http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3560/software/release/12-2_52_se/configuration/guide/3560scg/swvtp.html

    Q7
    the question asks for an enhancement to stp-design. I do not think vtp pruning prevents BPDUs (which could turn out in being no good). So changing the stp-designs points to eliminating vlans which in turn means manual pruning.

Like how he has packet tracer available for 3 of the simulations. It was good practice. No new questions.

    Q10 – asks which VTP mode : 4 modes – client, server, transparent, no : so when a switch is configured to use VTP version 1 or 2 – only mode is transparent to use extended vlans on these switches

    Passed my Switch Exam! 191Q is valid. I’m pretty sure information on this site is helpful but I used study materials from this ebay seller I came across on my CCNA/CCNP Route cert prep journey. He tends to have the latest updates for all the exams he provides. He seems to not have the TShoot Cert Prep but will see if he has that lol. Onto completing my CCNP Certification!

    Information to the exam:

    37 Multiple Choice Questions
    OSPF TShoot Simlet
    LACP-STP Simulation
    AAAdot1x Simulation

    If you would like to use the study materials I used, here is the ebay link:

    Cheers and Good Luck!
