A. B. C. D. E.DE.
The EtherChannel technology allows the bundling of multiple physical links between two switches into a single logical link. This provides higher bandwidth, better utilization of available links, and redundancy.
To configure EtherChannel negotiation, there are four modes available:
- On: the channel is created without negotiation.
- Passive: the channel listens to negotiation requests from the other end but does not initiate them.
- Active: the channel actively initiates negotiation requests.
- Desirable: the channel initiates negotiation if the other end is set to active or desirable, but not if it is set to on or passive.
Based on the above description, the correct answers are B (channel-group 10 mode auto) and D (channel-group 10 mode desirable). These two commands allow the switch to negotiate the creation of the EtherChannel link with the remote switch, ensuring that both ends agree on the parameters before the link is established.
Option A (channel-group 10 mode on) creates the EtherChannel without negotiation, so it does not allow negotiation with the remote switch.
Option C (channel-group 10 mode passive) allows negotiation requests from the remote switch but does not initiate them, so it is not a suitable option for actively negotiating EtherChannel.
Option E (channel-group 10 mode active) actively initiates negotiation requests, but it does not ensure that the remote switch is set to a compatible mode, which could cause negotiation failure.
