• Question 307:

  Your customer has asked you to come in and verify the operation of routers R1 and R2 which are configured to use HSRP. They have questions about how these two devices will perform in the event of a device failure.

  

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

  ---

  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.
