Ethernet defines MAC addresses, but when used in a TCP/IP network, it does not use the addresses, instead relying on IP addresses. c. Ethernet works as a broadcast network, with no data-link addresses, so all devices (including PC2) receive the data. d. PC1 cannot send data directly to PC2 in this network. 14. Which of the following are true facts about IP addresses? (Choose two answers.) a. 48 bits in length b. Can be written in DDN format c. Are listed in the data-link trailer d. Used by routers to make a forwarding decision 16. Which of the following statements is true comparing LANs and WANs? (Choose two answers.) a. LANs generally connect devices that are nearer to each other, compared to WANs. b. WANs are purchased, and LANs are leased. c. WANs generally connect devices that are nearer to each other, compared to LANs. d. LANs are purchased, and WANs are leased. 18. Which of the following answers list true facts about the network layer of TCP/IP? (Choose two answers.) a. It focuses mostly on the network between endpoints, rather than the endpoints. b. The two primary protocols are TCP and IP. c. IP provides logical addressing and routing
