    c.       vtp mode client
    d.      vtp client mode

    b.      Stop unnecessary VTP adverts
    c.       Limit the extent of broadcast traffc
    d.      Limit the size of the virtual tree

    c.       1000
    d.      1001

    b.      All other switches in the domain must be version 2 capable
    c.       All other switches must be configured for VTP version 2

  13. How are VTP advertisements sent?
    Using multicast frames.
  14. What gets advertised during a VLAN advertisement??
    VLANs 1-1005, Rev numbers, and VLAN parameters.
  15. T/F  By default, are management domains set to use  non-secure adverts without a password?
  16. What increment does a VTP advert start with?
  17. What 2 ways can be used to initialize a VTP  rev number back to 0?
    1.       Change sw mode to transparent then back to server.

    2.       Change vtp domain to bogus name, then change back to correct name.
  18. Describe VTP synchronization problem.
    Where a new sw is put on the lan without its VTP database being zeroized. If it has a higher rev number, all other switches sync to it.  This will flush all your VLAN info from all switches. 
  19. What are the 3 forms of VTP adverts?
    1.       Summary adverts.  Every 300 seconds or when a change occurs.

    2.       Subset adverts.  These list specific changes to the VLAN database.

    3.       Advert request from client.
  20. What cmds config VTP?
    • vtp mode {server | client | transparent}
    • vtp password newt

    Note.  If in secure mode, MD5 algo hash is sent.  Other switches also need to have the password added to them.
  21. How many versions of VTP can be run? 

    Can they interoperate?
    2,  VTP ver 1 and VTP ver 2.      

  22. What does VTP ver 2 add over VTP ver 1?
    Version-dependent  transparent mode – ver 1 had to check domain mode before forwarding.

    Consistency checks – checks for errors when using CLI

    Token ring support (ver 2 only)

    Unrecognized Type-Length-Value(TLV) support –
  23. What cli cmds allow you to see VTP status and sequence?
    sh vtp status

    sh vtp counters
  24. Is VTP pruning enabled or disabled by default on IOS based switches?

    Note:  when VTP pruning is enabled, there is an instance of STP running on the trunk link for every VLAN.  You should manually prune unneeded VLANs from the trunk.  Use cli:  int fa 0/1Switchport trunk pruning vlan (add/except/remove) vlan-list  (none)
  25. What are the VTP troubleshooting commands?
    sh vtp status

    sh vtp counters

    sh vlan brief

    sh int fa 0/1 switchport

    sh int fa 0/1 pruning
