Answers

1.	A, D, F Media problems are related to utilization, protocol problems are usually caused by excessive broadcasts, and transport problems can be caused by bandwidth limitations.
2.	A Protocol problems defined in Cisco’s Small- to Medium-Sized Business Solutions Framework are usually related to excessive broadcasts.
3.	B According to Cisco’s Small- to Medium-Sized Business Solutions Framework, media problems can be solved by reducing the size of collision domains.
