Which combination of modes establishes an EtherChannel?

  • Switch 1 set to auto; switch 2 set to auto.
  • Switch 1 set to auto; switch 2 set to on.
  • Switch 1 set to desirable; switch 2 set to desirable.
  • Switch 1 set to on; switch 2 set to desirable

Explanation: Switch 1 and switch 2 establish an EtherChannel if both sides are set to desirable as both sides will negotiate the link. A channel can also be established if both sides are set to on, or if one side is set to auto and the other to desirable. Setting one switch to on prevents that switch from negotiating the formation of an EtherChannel bundle.
