Hi

It should be A, C and D.

[jonk34567]

is DTP cisco proprietary ?

[Julio E. Moisa]

Hi

Yes, it is.

DTP is a Cisco proprietary protocol that is automatically enabled on Catalyst 2960 and Catalyst 3560 Series switches. Switches from other vendors do not support DTP. DTP manages trunk negotiation only if the port on the neighbor switch is configured in a trunk mode that supports DTP.

if we have to establish a trunk link between cisco and hp devices what protocol do we have to use ?

Hi 

You should use encapsulation dot1q and mode trunk.
