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.
