Answer: D - Frame Relay uses Inverse ARP to map DLCIs to IP addresses.

Key Takeaway: The locally significant DLCI must be mapped to the destination router's IP address. The two options to do this are Inverse ARP and static mapping. Inverse ARP runs by default once Frame Relay is enabled and starts working as soon as an interface is opened. If the show frame-relay map shows a dynamic mapping, it indicates that Inverse ARP was used for mapping.
