What is used to identify the path to the next Frame Relay switch in a Frame Relay network? |
DLCI |
|
|
Why are Frame Relay paths referred to as virtual? |
There are no dedicated circuits inside the Frame Relay carrier cloud. |
|
|
Which statement accurately describes the split horizon problem with regard to a multipoint topology? |
Split horizon prevents any interface from accepting a valid update and forwarding to all the other interfaces. |
|
|
Why is Frame Relay more cost-effective than leased lines? (Choose two.) |
It uses less equipment. It shares bandwidth across a large customer base. |
|
|
What reliability advantage does Frame Relay offer over leased lines? |
The pathways for virtual circuits inside the carrier are meshed. |
|
Refer to Figure below. What is placed in the Address field of a frame that will travel from the Orlando office to the DC office? |
DLCI 100 |
|
|
Which situation favors a multipoint topology over point to point? |
When VLSM cannot be used to conserve addresses |
|
|
What is an advantage of configuring subinterfaces in a Frame Relay environment? |
It solves split horizon issues. |
|
|
Which protocol can provide error correction for data that is transmitted over a Frame Relay link? |
TCP |
|
|
At which rate does a service provider guarantee to transfer data into the Frame Relay network? |
Committed information rate |
|
|
How are DLCI numbers assigned? |
They are assigned by the service provider |
|
|
A router can reach multiple networks through a Frame Relay interface. How does the router know which DLCI to assign to the IP address of the destination network? |
It consults the Frame Relay map. |
|
|
Compare and contrast the following terms: DLCI, LMI, and Inverse ARP |
DLCI – Data-link connection identifier LMI – Local management Inverse ARP – address resolution protocol |
|
|
17) Compare and contrast the following terms: access rate, CIR, CBIR, and Be. |
Access rate or port speedCIR: committed information rateCBIR: committed burst information rateBe: Excess burst |
|
