27. Which type of bridge is used on token ring networks?
[A] Transparent Bridge
[B] Translational Bridge
[C] Source Route Bridge
[D] All of the Above
Show Answer
Correct Answer: D [All of the Above]
Notes:
Source route bridge is used on token ring networks. Bridge derives the entire path of the frame embedded in the header of the frame and decides how to forward the frame through out the network till it reaches its destination.
28. What is the time needed by each device on a network, to hold the message before processing, called as?
[A] Propagation time
[B] Queuing time
[C] Transmission time
[D] Jitter
Show Answer
Correct Answer: B [Queuing time]
Notes:
The time needed for each intermediate or end device to hold the message before it can be processed. The queuing time is not constant as it changes with the load imposed on the network.

30. Which of the following is a disadvantage of using twisted paired cables for transmitting data?
[A] High cost
[B] Installation is difficult
[C] Delay Skew
[D] All of the above
Show Answer
Correct Answer: C [Delay Skew]
Notes:
Twisted paired cables are cost-effective and easy to install. But different pairs within the cable have different delays, due to different twist rates that are used to minimize crosstalk between the pairs.
