Q. 7
Exhibit:
Which Frame Relay feature allows the point-to-point Frame Relay PVC between Router A and Router B
to be identified at Router A as 100 and at Router B as 200?
A. Locally significant DLCI
B. Globally significant DLCI
C. Locally significant LMI
D. Globally significant LMI
Answer: A
Explanation:
The DLCI (Data-Link Connection Identifier) is a number that identifies the logical circuit between the router
and the Frame Relay switch. The Frame Relay switch maps the DLCIs between each pair of routers to create a
PVC. DLCIs have local significance in that the identifier references the point between the local router and the
Frame Relay switch, which it is connected.
