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.

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.”

    Thanks god just pass SW 300-115.
    TestKing dump is valid, labs are the same as cerprepare: LACP and HSRP. Not many new questions which similar to the dumps.

    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.

    just want to confirm this lab will be included in the ccnp exam right?

    Nobody knows if this lab will be in the exam. There are several exams but if you read the comments you get a general idea

    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!
