A.
to map a known IP address to a MAC address

B.
to map a known DLCI to a MAC address

C.
to map a known MAC address to an IP address

D.
to map a known DLCI to an IP address

E.
to map a known IP address to a SPID

F.
to map a known SPID to a MAC address

Explanation:
Dynamic address mapping relies on the Frame Relay Inverse Address Resolution Protocol
(Inverse ARP), defined by RFC 1293, to resolve a next hop network protocol (IP) address to a
local DLCI value. The Frame Relay router sends out Inverse ARP requests on its Frame Relay
PVC to discover the protocol address of the remote device connected to the Frame Relay network.
The responses to the Inverse ARP requests are used to populate an address-to-DLCI mapping
table on the Frame Relay router or access server. The router builds and maintains this address-toDLCI mapping table, which contains all resolved Inverse ARP requests, including both dynamic
and static mapping entries.
