LACP Port Negotiation 1) Active - Passive 2) Active - Active 3) ON - ON

No only Active - Active or Active - Passive ON means that the port will become part of the EtherChannel without negotiating with the other end (neither LACP nor PAgP).

C is correct. London is configured at LACP but New York is PAGP. New York needs to be reconfigured for LACP. Active - Passive or Active - Active.

C is correct As we have LACP on the London side. Then we have to remove the PAgp on the NY side and configure it as passive for LACP. Active and Passive are forming etherchannel for LACP.

Answer is C. New York is currently in PAgp mode, and London has been configured as LACP. So we need to change NewYork to LACP, which makes the answer C.

I think the ans should be D. LACP - Active/Passive. PAGP - Desirable/auto.

Right, so answer D won't work, since for D, you're setting it back to PaGp which has been the problem all along. London is Active (LACP) so NY also has to be LACP

London is LACP Protocol, NewYork is PAgP Protocol. None of the answers are correct.

Right, so that's why for NY, which all answers have you reconfigure, you want to set as LACP, which answer C does. Granted C has it set to passive, but London is active so that's OK.
