Q6. Frame Relay DLCIs must be unique in a Frame Relay network.



Correct Answer: B


DLCI stands for Data-Link Connection Identifier. Frame Relay DLCIs have local significance, which means that the values themselves are not unique in the Frame Relay WAN. DLCIs must be unique on a given access link, i.e. the physical channel on which they reside.
