iii. The diagram given below depicts the switched network in SLTC Padukka premises. F0/1 S1 F0/6 FO/1 S2 F0/18 PC-A PC-B M Figure 1: The LAN of SLTC Padukka premises a. Assume that the MAC address of each PC holds its letter i.e. A for PC-A and B for PC- B) for all the hex decimal values. Define the MAC address of each PC. (2 marks) b. Draw the Ethernet frame structure generated at PC-A destined to PC-B. (2 marks) c. Build the Content-Addressable Memory (CAM) table in switch S1, when the above frame arrives at S1. Assume that the CAM table is empty. (2 marks) d. Build the CAM table in switch S2, when the above frame arrives at S2. Assume that the CAM table is empty. (2 marks) iv. Compare and contrast two well-known ALOHA methods. Illustrate necessary diagrams for your explanation. (3 marks) v. Briefly explain the behaviour of three persistent methods used in CSMA with relevant timing diagrams or flow diagrams. (3 marks) vi. Describe the overall operation of CSMA/CD protocol with suitable diagram. Explain key strategies used to mitigate further vulnerability for frame transmission. Provide a technology application of this protocol
