D. switch1 channel-group 1 mode desirable switch2 channel-group 1 mode auto uestion 2 After an EtherChannel is configured between two Cisco switches, interface port channel 1 is in the down/down state. Switch A is configured with “channel-group 1 mode active”, while Switch B is configured with “channel-group 1 mode desirable”. Why is the EtherChannel bundle not working? A. The switches are using mismatched EtherChannel negotiation modes. Question 3 An EtherChannel bundle has been established between a Cisco switch and a corporate web server. The network administrator noticed that only one of the EtherChannel links is being utilized to reach the web server. What should be done on the Cisco switch to allow for better EtherChannel utilization to the corporate web server? E. Adjust the EtherChannel load-balancing method based on source IP addresses. Question 4 An access switch has been configured with an EtherChannel port.
