3. You run the "Show frame pvc 200" command on your router which has a VC connected to another router. The Local DLCI on your router's VC is 200. The status code is "Deleted" What does this code mean?

5. Router-A has a Virtual circuit number of 100 and sends a packet across this circuit and to Router-B who waits on the other side. Router-B's virtual circuit number for this connection is idenitifed by 200. When the packet left router A and went through the cloud and to Router-B, how many fields in the frame relay header were used to identify the VC?

One

Two

None

Three

There is only one DLCI field in the FR header and this field would have started off as 100 in this example. Then as it traversed the cloud, the provider would have removed 100 and put DLCI 200 in its place. The end to end DTE devices would not have been aware of this as DLCIs are locally significant

16. If you type the "no keepalive" command on your router's serial interface connected to the frame relay network. How will this effect the VC status when you run the show frame pvc

Static

Deleted

Active

Inactive

No keepalive will disable LMI messages being sent which means the FR switch cannot tell the DTE if the VC is active,inactive or deleted. So it reverts to static status.
