• Question 933:

  While doing network discovery using Cisco Discovery Protocol, it is found that rapid error tracking is not currently enabled. Which option must be enabled to allow for enhanced reporting mechanisms using Cisco Discovery Protocol?

  A. Cisco Discovery Protocol version 2
  B. Cisco IOS Embedded Event Manager
  C. logging buffered
  D. Cisco Discovery Protocol source interface
  E. Cisco Discovery Protocol logging options
  A. Cisco Discovery Protocol version 2

  CDP Version 1 -- This is the first version of CDP which was used for the discovery of Cisco devices in the network. This version is mainly used for backward compatibility.

  CDP Version 2 -- This is the most recent version of CDP which has enhanced features such as rapid reporting mechanism, which is used to track down errors and minimize costly downtime. It allows you to track instances even if the native

  VLAN ID or port duplex states do not match between connecting devices.

  This is the default version on all switches.

• Question 935:

  

  VTP Domain name : cisco VLAN Ids 20 31 IP Addresses 172.16.71.1/24 172.16.132.1/24 These are your specific tasks:

  1.

  Configure the VTP information with the distribution layer switch as the VTP server

  2.

  Configure the VTP information with the access layer switch as a VTP client

  3.

  Configure VLANs on the distribution layer switch

  4.

  Configure inter-VLAN routing on the distribution layer switch

  5.

  Specific VLAN port assignments will be made as users are added to the access layer switches in the future.

  6.

  All VLANs and VTP configurations are to completed in the global configuration To configure the switch click on the host icon that is connected to the switch be way of a serial console cable.
