VTPv3 Sim

February 11th, 2017 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

In VTP version 3, there are two additional fields under the output of “show vtp status” command. They are:
+ “Primary ID”: The MAC address of the Primary Server
+ “Primary Description”: The hostname of the Primary Server

The Primary Server is used on VTP version 3 to avoid the bad behavior in version 2. In VTP version 2, a VTP client (or Server) can be taken out of the network. When it comes back, it can overwrite a VTP Server if its Revision number is higher. This problem no longer exists in VTP version 3 because there is only one VTP Primary Server at a time. Only a VTP Primary Server can create new VLAN.

After creating new VLAN, the VTP Primary Server will advertise its VLAN database to other VTP clients/servers so in fact answer A is not correct. In this question you just need to check if Sw1 or Sw2 is the VTP Primary Server then we can create both VLAN 500 & 600 on it. Then it will advertise these VLANs to other switches.

Sw1_show_vtp_status_primary_server.jpg

From the output we see Sw1 is the Primary Server so we should configure VLAN 500 & 600 only on this switch.

Note: If the above output shows the roles of Sw1 and Sw2 are “Server” only (not “Primary Server”) then we should choose: A. Configure VLAN 500 & VLAN 600 on both SW1 & SW2

Note: To make a switch a Primary Server, issue the “vtp primary vlan” under privilege exec mode. For example:

Sw1#vtp primary vlan

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.”

    Q3 – can be A or B
    if VTP operating mode of both SW1 and SW2 are server and version 3, answer is A
    if VTP operating mode of SW1 is primary server on version 3, answer is B

    April 13th, 2015

    might be an easy question but i should ask: in the answer to Q1 it says “although Transparent mode is acceptable”. Why? and what has vtp got to do anything with PC1 communication with PC2?

  3. Yvos21
    April 14th, 2015

    @asker
    if vtp configuration is not correct, PC1 cannot communicate to PC2. That’s the goal, so correct VTP config is required.

    April 17th, 2015

    I think the Q3 should be in SW1 and SW2 it I do not think primary influences that can be ROOT for a vlan and root for other albeit SECONDARY.
    -I have tried it in GNS3 with MLSIOU and let me do a root switch AS ROOT FOR OTHER PRIMARY and SECONDARY BEING VTP

    boys-some idea? thanks

    Question 3 answer in another PDF dumps was A, because switch 1 and 2 both server mode.
    here the answer is B because switch1 is the primary one.
    I got confused, please provide the help in this question.

    let me share my little experience with you in this :

    why we need to create vlans 500 and 600 on both switches while both switches in server mode so already if the vlans created on switch 1 or 2 it will move to another switch . ” as I know switch in server mode can send and receive vlans ”

    so that make the answer B more sense to me.
    but I still confused :d

    Q3 Correct Answer: A
    Explanation:By issuing the “show vtp status command on SW2, SW2, and SW4 we see that both SW1 and SW2 are operating in VTP server mode, but SW4 is a client, so we will need to add both VLANs to SW1 and SW2.

    Question 3 discussion – Don’t over-complicate it.

    Read the question – specifically the last sentence – which is the question. “Which configuration step is valid?” This question implies which ONE step is a valid step in achieving the configuration?

    Look at the VTP status – SW1 is the primary server. Since we must create the VLANS, and since we create VLANS on the primary server in VTP version 3, we create both VLANS 500 and 600 on SW1. This is THE valid step.

    Q3

    SW1 – Primary Server SW2 – Server -> ans “B”

    SW1 – Server SW2 – Server -> ans “A”

    ;)

  12. 3Aor3B
    May 16th, 2015

    Come on folks – this question is cisco way of tricking you … they have included “spanning-tree” to throw you off the obvious VTP v3 related answer which is “B” as SW1 is the primary VTP server and the only place to add the vlans !!! … if it were a “choose 2” options then then F would look something like .. “modify spanning tree on SW1 and SW2” in which case the answer would b and f but since the wording is the way it is it can only be “B”

    As those who think that if Sw1 is primary then B or if just a server then A, again you are wrong .. to add vlans one of them has to be a primary under vtp 3 rules if you don’t make it a primary then all vtp servers are secondary and you have no way of adding new vlans !!!

    Hi there,

    i did the exam recently and there is no primary server as mentioned above.

    On Q3 you couldn’t just check show vtp status and check which one of the switches is primary and that’s it.

    although vtp was version 3 on both switches, there was no primary server configured.

    Just check “primary ID” under vtp operating mode and you will see which switch is chosen as the primary one. the answer will be the same as above.Answer B

    Regarding q3 – Sam (February 27th, 2015) is right, in Galvins dumps there is different output of show vtp status on SW1 – mode: server, not Primary server like here, so it all depends on the output of these command on SW1 and 2
    so
    choose A if a show command on sw1 and sw2 are server mode
    choose B if a show command on sw1 is primary server mode
    choose C if a show command on sw2 is primary server mode

    Labs dot1x,hsrp,lacp with stp and vtp v3. Please use vtp v3 show in galvin dump.

    I failed because:
    1. i configured vlan map on ASW1 instead of DSW1
    2. i forgot to configure portfast on the LACP sim
    3. i forgot to make switchA the root on LACP simulation

    4. I DID THE EXAM WITHOUT READING INSTRUCTIONS SINCE I HAD READ EVERYTHING ON certprepare

    Guys please take these sims very seriously but use galving for the vtp v3 sim

    Hi There,

    I’m bit lot about the Q4. The comments above are valid, but I cannot the answer with best match !!
    Two facts:
    1) private Vlan are propagated by VTP v3. Not supported in v1/2, there is required transparent mode setting
    2) in v1/2 pruning is propagated but not in v3, where manual enabling is required on each switch.

    PLs can anyone help me ? Txs

    Question 3 answer is incorrect. The answer should be A.

    This question has two parts:

    Part 1: Adding VLANS
    Part 2: Setting STP Root priority values.

    Part 1 is as other commenters described. VLANs can only be added on the VTP version3 primary server (SW1). If the question ended here, B would be the correct answer ***BUT*** PART 2 specifies that SW1 is the primary Spanning-Tree root for VLAN 500 and secondary for VLAN 600 ***AND*** SW2 is the primary STP root for VLAN 600 and secondary for VLAN 500. You cannot modify the Spanning-Tree VLAN priority through VTPv3….it is a Spanning-Tree global config command.

    To configure the STP vlan root priority, you use the global config command “spanning-tree vlan {#} root {primary/secondary}. This command changes the STP priority for the vlan from default to 24576 for primary and 28672 for secondary. This must be done on each switch you wish to have as the root in a spanning-tree bridged network, in this case both SW1 & SW2.

    SW1#(config) vlan 500
    SW1#(config) vlan 600
    //Vlans are created and propagated by VTPv3 to all Switches

    SW1#(config) spanning-tree vlan 500 root primary
    SW1#(config) spanning-tree vlan 600 root secondary

    SW2#(config) spanning-tree vlan 500 root secondary
    SW2#(config) spanning-tree vlan 600 root primary

  33. superuser

    Q3. You are adding new VLANs: VLAN500 and VLAN600 to the topology IN SUCH A 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?

    its say ADDING new VLAN – you can configure only in the primary server because there is only one primary server in one domain.

    The choices in the question says CONFIGURE VLAN. so ignore the question says ” IN SUCH A 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.”

    so answer is whosoever the Primary Server

    Verify each switch by show vtp status on switch 1, 2 and 3. 1 and 2 are operating in server mode and 4 is operating in client mode. So VLAN 500 and 600 must be created on both switches.

    But if switch 1 is running in primary server mode then both vlans 500 and 600 would only be create on switch 1.

    In primary server we would create all the vlans on primary server.

    In regards to Q3
    http://www.cisco.com/c/en/us/products/collateral/switches/catalyst-6500-series-switches/solution_guide_c78_508010.html

    client and secondary server devices receive a configuration from a primary server. A secondary server stores the received configuration in a local permanent storage space (for example, NVRAM) and updates other devices in the same domain and for the same instance. In the case of VTP version 1 or VTP version 2, a server can be manually configured via command-line interface (CLI) or Simple Network Management Protocol (SNMP). In VTP version 3, a secondary server cannot be configured manually but can receive updates, similar to a device owning the client role.

    so look for the primary and choose the correct answer.

    i set this up in packet tracer using only vtp ver 2 but if your switches are in client mode the server propagates the vlans across and you would not have to create vlans on other client switches only the server

    i am sure the same for vtp ver 3 server mode. i agree with another poster above that the spanning-tree part if just there to throw you off a little

    What about question 3 from the VTPv3 Sim? Since there are also primary and secondary root requirements, wouldn’t the configurations need to be completed on both SW1 and SW2 – hence answer A? If the question was only asking for the creation of the VLANs without the primary and secondary root requirements, then the VLANs could be configured on the VTPv3 primary server and the answer would be B, correct?

  49. whoooaa
    September 1st, 2015

    Hi guys as its my first da to switch i read comments. and i think the question is asking about configuring the vlans. and not creating vlans.
    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?

    So if we create new vlans it will be just done on SW-1.. But configuring vlans as pri/sec on both switches. we have to configure on both as it cant be done via SW-1
    Reffering to @WALLY comment

    Sw1(config)#vtp primary vlan 500 (automatic secondary for any other vlan, ie vlan 600)
    Sw2(config)#vtp primary vlan 600 (automatic secondary for any other vlan, ie vlan 500)
    Thus, the closest answer is A.

    What you guys think.. that is my point of view

  50. whoooaa
