Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. What are two reasons why the ping messages that are issued from Laptop0 towards Laptop1 are failing? (Choose two.)
- The two interfaces on each of the switches belong to different VLANs.*
- The interface VLAN 1 is shut down on both switches.
- The channel group mode is not set correctly on the switches.
- The wrong cable types are connecting the two switches.
- The channel group should be configured as a trunk on each switch.
Explanation: Port-channel 1 needs to be configured as a trunk in order to carry data about two different VLANs. The channel group is set as auto and desirable. The SVI has not been configured on the switches, but this does not affect the creation of an EtherChannel. The use of straight-through cables between switches is not an issue when using a Cisco Catalyst 2960 switch.
