Which protocol communicates between a router and the local Frame Relay switch?
24
a. ILMI
b. MAP
c. NNI
d. LMI
Which feature uses BECN bits as input to control the flow of frames into the network?
25
a. The DE bit
b. Traffic shaping
c. Priority queuing
d. Compression
What is Frame Relay's advantage over X.25?
26
a. Its advanced error checking features.
b. It is connection-oriented.
c. It adds less overhead; therefore, it is available at greater speeds.
d. It is designed to run over bad cable systems.
You have a Frame Relay network between Router A and Router B. Host 1 and Router A
are on one side, and Host 2 and Router B are on the other. Host 1 transmits a packet to
Host 2. The frame is discarded in the wide-area network. Which device is responsible for
retransmitting?
27
a. Host 1
b. Router A
c. Router B
d. The link-layer protocol on the Frame Relay switch
You have an X.25 network between Router A and Router B. Host 1 and Router A are on
one side, and Host 2 and Router B are on the other. Host 1 transmits a packet to Host 2.
Router A forwards the frame into the network, and the frame is discarded. Which device
is responsible for retransmitting?
28
a. Host 1
b. Router A
c. Router B
d. Host 2
