What is the distance limitation for 100BaseT?

640 - 607

Incorrect Answers:

A is incorrect; this would require all NICs to be upgraded, and result in a large collision domain with possible poor performance.

B is incorrect; a router would become a bottleneck, and not allow efficient performance.

D is incorrect; a bridge would be a bottleneck, and not be able to provide the necessary performance and throughput.

Q. 101

A network is very congested. Currently all the devices are connected through a hub. Which solution would best decrease congestion on the network?

A.Add a second hub

B.Replace the hub with a router.

C.Replace the hub with a switch.

D.Replace the hub with a repeater.

Answer: B

Explanation: A router would break each segment into their own collision domains and broadcast domains. This would reduce network congestion the most.

Incorrect Answers:

A is incorrect; there will still be one collision domain which would mean that the network would still be congested.

C is incorrect; if money were a factor in your solution to network congestion then this would be the best option. D is incorrect; a repeater does not affect congestion.
