a) frame-relay switch-type
b) frame-relay lmi-type switch
c) frame-relay switching
d) frame-relay map

Answer
c) frame-relay switching

Explanation
In order to configure a Cisco router to act as a Frame Relay switch, you need to use the frame-relay switching command in global configuration mode. This command enables Frame Relay switching on the router, but does not provide a data-link layer path between the PVCs configured on the switch, which is done using the frame-relay route command.

Question 3.
Which of the following characteristics differentiate a WAN from a LAN?

a) geographic scope
b) cost
c) administrative control
d) speed

Answer
a) geographic scope
c) administrative control

Explanation
Several characteristics of WANs differentiate them from LANs. WANs certainly span a larger geographic scope than LANs. While a LAN is limited to a single building or group of buildings on a campus, a WAN often consists of sites in multiple cities or countries. Another distinguishing factor is administrative control. While a LAN is usually controlled entirely by the company that uses it, WAN links are subject to administrative control from the carriers that provide or lease the lines to the company that uses them. Cost is not a distinguishing factor, since both LANs and WANs can vary widely in cost, depending on the technology implemented. Speed alone is not a distinguishing factor. Currently, there are WANs that operate at very high speed, comparable to today's LAN operating speeds.
