MIS 3200 Networking FundamentalsReview ExerciseConsider the network design illustrated in Figure 3-18, and answer the following questions.Q.1.. Suppose that, due to some renovations done in the building, the distance between the Workstation and the Hub is now more than 100 meters. What kind of problem this could create? a) Interference b) Attenuation c) Shadow zones d) None of the aboveQ.2. Now, suppose that in order to solve the problem created by the building renovation, a decision is made to replace the Category-5 UTP by a fiber optic cable. Will this solve the problem? Discuss the consequences of that decision in terms of cost. Be very specific in determining the components of the cost.Answer: __________________________________________________________________ __________________________________________________________________ __________________________________________________________________ __________________________________________________________________ __________________________________________________________________ __________________________________________________________________Q.3. Now, suppose that before the building renovation, the Category-5 UTP cable that connects the Workstation and the Hub passes near a heating and cooling mechanical system. What kind of problem(s) this can create? (Choose one)a. Attenuationb. Noisec. Interferenced. None of the above Page 1 of 2Crossover cableQ.4 In data transmission, noise refers toa. Receiving a direct and an indirect signalb. Radiation emitted by one wire and picked up by a second wirec. Random electric energy generated in the transmission media when the signal is being transmitted.d. None of the aboveQ.5. Which of the following is true if a signal loses 1/2 of its power during the course of a transmission over Category 5 cable?a) The decibel lost is - 2 dbb) The decibel lost is - 4 dbc) The decibel lost is - 5 dbd) None of the aboveQ.6. Which of the following is true if in a wireless transmission using radio waves, the distance between the sender and the receiver is to double?a) There will be too much interferenceb) The receiver will only get about half of the original signal strengthc) The receiver will only get about 1/3 of the original signal strengthd) None of the aboveQ.7 Shadow zones can be a major issue with wireless transmission. Explain shadow zone in wireless transmission and provide some examples of situation where it may occur.Q.8. Which of the following is true if a signal loses 1/4 of its power during the course of a transmission over Category 5 cable?a) The decibel lost is - 2 dbb) The decibel lost is - 4 dbc) The decibel lost is - 5 dbd) None of the above Page 2 of 2If needed, you can use any the following equations in answering some of the questions.Attenuation in dB = 10 log10 (P2/P1) (Formula 1)Distance multiplier Signal strengthN 1/2N (Formula
