• Question 32:

  A network administrator has configured a 4-port port-channel between two Dell EMC Campus networking switches. The physical interfaces show as administratively up and operationally up on both switches. However, the port-channel shows as operationally up on Switch A and operationally down on Switch B.

  What is a potential reason for the inconsistent port-channel state?

  A. Switch A is configured to use dynamic port-channels and Switch B is configured to use static port-channels

  B. Ports in the port-channel on Switch A are all the same speed but the ports in the port-channel on Switch B are a mix of speeds

  C. Switch A is configured using channel-group # mode on and Switch B is configured using channel-group # mode auto

  D. N-Series supports a maximum number of physical interfaces that can be included in port-channels on a per-device basis

  Correct Answer: C
