How many bytes of overhead are there in an Ethernet frame? Include the header and trailer. but do not include the preamble in the frame. You will need to look up the length of the header and trailer. , An Ethermet frame contains 600 bytes of payload data., Calculate the percentage of the frame that is overhead (do not include the preamble in the frame). ( number of overhead bytes calculated in the problem above.) You will need to use the Assume an Ethernet frame is to carry only 30 bytes of payload data. How many bytes of padding must be added to the frame? 9. 10. State whether there will there be a collision in each of the following situations. a. Two hosts ransamit through a hub simutancously. b. Two hosts transmit through a full-duplex switched Ethernet switch simultaneously c. A host and the switch transmit through a half-duplex switched Ethernet simultaneously. A switched Ethernet local area network contains the following devices: - A switch with 4 ports, numbered 1-4. - Host A (MAC address AA-AA-AA-AA-AA-AA) connected to port 1 - Host B (MAC address BB-BB-BB-BB-BB-BB) connected to port 2 - Host C (MAC address CC-CC-cc-cc-CC-CC) connected to port 3 - A gateway router (MAC address DD-DD-DD-DD-DD-DD) connected to port 4 11. a. Sketch the LAN. b. Show the forwarding table inside the switch 12. A switch and a NIC are negotiating a connection. The switch operates at 100Mbps and 1000 Mbps. The switch supports both half-duplex and full-duplex connections. The NIC operates at 1000 Mbps and 10000 Mbps. The NIC supports both half-duplex and full- duplex connections a. After the negotiation, what speed will the link operate at? b. Will it be full-duplex or half-duplex? 13. Your boss wants to upgrade your full-duplex switched Ethernet local area network from 100BaseT to 1000BaseT a. Assume the existing NICs in your hosts are full-duplex and operate at 10Mbps and 100Mbps. Will you need to upgrade the NICs to be able to run at 1000 Mbps? b. Assume the existing switch is full duplex and operates at 10Mbps, 100Mbps, and 1000Mbps. Will you need to upgrade the switch to be able to run at 1000 Mbps
