It has become necessary to configure an existing serial interface to accept a second Frame Relay virtual circuit. Which of the following processes are required to accomplish this task?(choose three)
A.
configure static frame relay map entries for each subinterface network.
B.
remove the ip address from the physical interface
C.
create the virtual interfaces with the interface command
D.
configure each subinterface with its own IP address
E.
disable split horizon to prevent routing loops between the subinterface networks
F.
encapsulate the physical interface with multipoint PPP
different dump give different answer, I see some mention ACD. Any confirm answer?

A is not required due to inverse arp. in point-to-point there is only one host on the remote end. To be honest this command is necessary only on point-to-multipoint subinterfaces which assigns DLCIs to corresponding remote IP addresses, and also can indicate the encapsulation type (cisco or ietf) on the end of the command, and also the option of broadcast keyword to send routing protocols’ updates.
