October 11th, 2018 in Lab Sim Go to comments

You have been asked to install and configure a new switch in a customer network. Use the console access to the existing and new switches to configure and verify correct device configuration.

VTP_Topology.jpg

Question 1

Explanation

To comply with the configuration of other switches, we need to get VTP configuration of Sw1 or Sw2. On Sw1 use the “show vtp status” command:

Sw1_show_vtp_status.jpg

From this output we learn on Sw1:
+ VTP is running version 3
+ VTP Domain is “CCNP”
+ Sw1 is the VTP Primary Server (we will explain about Primary Server later. Now just understand it is in VTP Server mode)

So on the New_Switch, the VTP Domain must match. New_Switch should run VTP version 3 if if can (but it is not a must as VTP version 2 is compatible with VTP version 3). The New_Switch is connecting to hosts so it is in Access Layer so it should be configured as a VTP Client (although Transparent mode is acceptable) so there are only two suitable choices D & E.

From the exhibit, the New_Switch is connecting to a host in VLAN 100 so its E0/0 interface should be in VLAN 100 -> only D is correct.

Question 2

Explanation

On Sw1 & Sw2 we can check with the “show interfaces trunk” command:

Sw1_show_interfaces_trunk.jpg

Sw2_show_interfaces_trunk.jpg

Sw1 & Sw2 are connected through E2/3 & E2/3 so we can see the native Vlan on these trunks are 99. We should check both Sw1 & Sw2 to see if the Native Vlan on both sides match.

Question 3

Explanation

Use the “show vtp status” on SW1 and SW2 we notice both of them are in “Server” mode so we should choose: A. Configure VLAN 500 & VLAN 600 on both SW1 & SW2.

In practical we only need to create VLANs on one of the “Server” switch and these VLANs will be propagated automatically to others “Server” and “Client” switch. But maybe it is not the answer Cisco wants (as it makes both answers B & C are correct).

Question 4

Explanation

To configure private VLAN we have to change VTP (even version 3) to Transparent mode. In fact, to disable VTP pruning on Sw4 (in Client mode) we also have to change to VTP Transparent mode so answer C can be understood as “change SW4 to Transparent mode” so it is the best choice.

Note: Unlike VTP version 1 and 2 in which VTP pruning is enabled on VTP Server only, VTP version 3 requires VTP pruning must be enabled on all the switches in the VTP domain so we can also disable VTP pruning on each switch separately. Here is the link for your reference: http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750x_3560x/software/release/12-2_55_se/configuration/guide/3750xscg/swvtp.html

“With VTP versions 1 and 2, when you enable pruning on the VTP server, it is enabled for the entire VTP domain. In VTP version 3, you must manually enable pruning on each switch in the domain.”

    I’m sorry for my ignorance.

    Question 1, PC1 is in VLAN 100, PC2 is in VLAN 200. How can they communicate with each other without a Layer 3 device?

    @antran SW1/2 are layer 3 switches

    @ccnp expires: Thank you! So the goal is to get a right VTP configuration for SW4 so it can join VTP domains of SW1 and SW2, which will allow communication between VLAN 100 and VLAN 200.

    Ok guys, with regards to Questions 3. It is all in the wording.

    If we look at the question, it clearly implies that vlans 500 and 600 are necessary for both SW1 and SW2 (we know this now).

    Now, obviously we know that if we were to apply a command for VLAN500 and 600 to SW1 (if it is primary server) then SW2 will also receive this via VTP and have VLAN 500 and 600 also. No one is disputing this fact.

    HOWEVER! Cisco is not asking us were to apply a command, it is asking ‘what configuration step is valid’.

    No matter what way it is done, no matter what command is used or were it is applied THE BOTTOM LINE IS that we MUST have Vlan 500 and 600 configured on both SW1 & SW2 in order to fulfil the STP requirements later. (obviously we don’t do this but this is the goal of the question)

    So the answer is:

    A. Configure VLAN 500 & VLAN 600 on both SW1 & SW2

    NOTE : none of the answers say ‘APPLY the command for VLAN 500 & 600 on both SW1 & SW2.’ etc.

    Simply put – We require VLAN 500 and 600 to be configured on both switches, how we choose to go about this and the commands we use to do it is completely irrelevant.

    Cisco are very sneaky with there wording, and this is a perfect example of it.

    Hi. For those who already took the exam? What is the answer for this ?

    SW2 as primary root for VLAN 600 and secondary for VLAN 500. Which configuration step is valid?
    A. Configure VLAN 500 & VLAN 600 on both SW1 & SW2
    B. Configure VLAN 500 and VLAN 600 on SW1 only
    C. Configure VLAN 500 and VLAN 600 on SW2 only
    D. Configure VLAN 500 and VLAN 600 on SW1 ,SW2 and SW4
    E. On SW2; configure vtp mode as off and configure VLAN 500 and VLAN 600; configure back to vtp server mode.

    Note: Some said that when they use the “show vtp status”, both sw1 and sw2 are in server mode. But how will i know where to config the vlan 500 and 600 if they are both servers? Is it based on the revision number, if which one is higher? Thank you so much in advance!

    isn’t Q3 about SPT root bridge priority? if it was ,we should launch “show spanning-tree ” to see priority of both switches SW1 & SW2.
    how can we configure vlan 500 as primary root and vlan 600 as secondary root on SW1 and
    viceversa fow SW2 without see SPT bridge priority?

  19. Cisco Kid
    June 1st, 2019

    Q3 is about creating the vlans, with VTP version 3 that needs to be done on the Primary Server which distributes the vlans over the other switches.

    With ‘show vtp status’ you can see which switch version is running and if it is the Primary Server in VTP Operation Mode
    (see example in Q1).

    is there a packet tracer lab for Vtpv3 sim?
    can you please post the link?

  21. pichy
    June 5th, 2019

    Q3 isn’t the answer the switch in VTP primary server mode only?
    one of the best things about vtp v3 was to try and prevent another newly connected switch to take over the server role in a vtp domain by creating a primary server. the other one is a secondary server and only a primary server can make configuration changes

    Passed with 904 yesterday!
    I got this lab, HSRP & AAA – Labs are valid.
    I also studied the IPHelper dump it includes some new questions.

    Question 3
    It’s VTPv3 so only 1 server should add VLANs. And in the “show vtp status” “Primary Description” says “SW1”.

    Q3. You are adding new VLANs: VLAN500 and VLAN600 to the topology in such way that you need to configure SW1 as primary root for VLAN 500 and secondary for VLAN 600 and SW2 as primary root for VLAN 600 and secondary for VLAN 500. Which configuration step is valid?

    A. Configure VLAN 500 & VLAN 600 on both SW1 & SW2
    B. Configure VLAN 500 and VLAN 600 on SW1 only
    C. Configure VLAN 500 and VLAN 600 on SW2 only
    D. Configure VLAN 500 and VLAN 600 on SW1 ,SW2 and SW4
    E. On SW2 configure VTP mode as off and configure VLAN 500 and VLAN 600; configure back to vtp server mode.

    According to the feedback received and simulation that what i think:

    – To create VLAN 500 and VLAN 600 you can do it only on SW1 because it is the primary server for the CCNP domain.
    – Once u create these VLANs on SW1, they will show up on SW2 as expected (trasnmitted over the domain…SW1 has the command)
    – The 3rd point and crucial on this question is the word @configure@. To configure VLANs as primary and secondary root we have to do it on each SW.

    With that said, A is correct in my opinion.

  27. masters90
    July 3rd, 2019

    Q4. Examine the VTP configuration. You are required to configure private VLANs for a new server deployment connecting to the SW4 switch. Which of the following configuration steps will allow creating private VLANs?

    A. Disable VTP pruning on SW1 only
    B. Disable VTP pruning on SW2 only
    C. Disable VTP pruning on SW4 only
    D. Disable VTP pruning on SW2, SW4 and New_Switch
    E. Disable VTP pruning on New_Switch and SW4 only.

    Regarding this question, here are my thoughts:

    – SW1 is the primary server for the domain so the private VLANs have to be configured here and then will be propagated throughout CCNP domain devices including SW4.
    – In order to create VLANs in VTP v3, mode has to be server/trasnparent (SW1 is primary server so this part is OK) and Pruning has to be turned OFF (not the case).
    – By Turning OFF Pruning on SW1, we can then create the private VLANs. SW4 and the others will inherit automatically that config even if PRUNING is enabled on SW4 (i simulated it).
    – BTW, SW4 has or should have VTP v3 mode Client since it connects to a host (similar to NEW _ SWITCH). Disabling here pruning would not bring any point.

    Well, looking forward for feedback and thoughts.

    About Q3
    You can only create VLAN 500 and 600 on SW1 because it is the Primary Server for VTPv3 domain.
    But the requirement is “that you need to configure SW1 as primary root for VLAN 500 and
    secondary for VLAN 600 and SW2 as primary root for VLAN 600 and secondary for VLAN 500”

    To do that the best choice is A: “Configure VLAN 500 & VLAN 600 on both SW1 & SW2”

    The answer is “Configure” not “Create VLAN”, isn’t it ?

  31. Scylla
    July 14th, 2019

    Q4.

    01.In order to configure private VLAN it is required to set VTP mode of the relevant SW to Transparent mode (this is a prerequisite of Private VLAN).

    02. VTP pruning is not designed to operate in transparent mode.Therefore if you operate one or more SWs in transparent mode it is required to disable VTP pruning on entire network if its run VTP Version 1 or 2. But if its run VTP V3, you can disable VTP pruning on individual SW.

    therefor in this case we need to configure private VLAN on SW4 and we need to set the VTP mode of SW4 as Transparent and as this network operate with VTP v3 we can disable VTP pruning on only SW4.

    Passed Yesterday with 867. All questions from Dumps (Little Modifications)
    Lab- HSRP (With Interface to R5). VTP V3. LACP with STP (After all Configurations, 3 vlan interfaces didn’t come up).

  39. Q4 answer
    August 11th, 2019

    Q4 answer C is fine.

    VTP pruning is not compatible with PVLAN so we need to disable it on switch.
    In VTPv3 enabling/diabling vtp pruning has to be done on every switch in the domain unlike it was in v1 and v2. So we nned to disable vtp pruning on SW4. Answer C.

    http://www.cisco.com/en/US/docs/switches/lan/catalyst3750x_3560x/software/release/12.2_55_se/configuration/guide/swvtp.html#wp1072526

    “With VTP versions 1 and 2, when you enable pruning on the VTP server, it is enabled for the entire VTP domain. In VTP version 3, you must manually enable pruning on each switch in the domain.”

  41. Lime
    September 5th, 2019

    Hi everyone,

    On question 3, the correct answer should be “B- Configure VLAN 500 and VLAN 600 on SW1 only “.

    -This is in reference to question 1, which shows that SW1 is the PRIMARY SERVER for the domain.

    -I’m also referencing Cisco’s White Paper on VTPv3 which states that “only one server per domain can be prompted to be a primary server.”
    -source: https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-6500-series-switches/solution_guide_c78_508010.html

    Hope this helps guys.

  42. Lime
    September 5th, 2019

    Oops, I stand corrected and I agree with Phonnv.

    You “create” VLANs 500 and 600 on SW1, the Primary Server. But you “configure” them as primary and secondary root on both switches, as STP config is not propagated by VTP.

    And the questions is asking for us to “configure” and not “create”. So the correct answer is actually “A – Configure VLAN 500 & VLAN 600 on both SW1 & SW2”

    Darn Cisco and their way with words.
