In which situation would the Cisco Discovery Protocol be disabled?

  • when a Cisco VoIP phone attaches to a Cisco switch
  • when a Cisco switch connects to another Cisco switch
  • when a Cisco switch connects to a Cisco router
  • when a PC with Cisco IP Communicator installed connects to a Cisco switch

Explanation: Cisco Discovery Protocol should be disabled on ports that do not connect to other Cisco devices. Even though the PC has a Cisco software product installed, the port to which the PC connects should have Cisco Discovery Protocol disabled because of the network information that can be derived from capturing Cisco Discovery Protocol messages.
