1.A and B are correct. Both Ethernet and Wi-Fi are Layer 1 and 2 protocol solutions. They define a Layer 2 solution that is usually called a MAC layer and a Layer 1 solution that is usually called a PHY layer. C and D are incorrect. Both TCP and UDP are Layer 4 protocols in the OSI model, and they are Transport layer protocols in the TCP/IP model.
2.A is correct. When FDDI was first released, it was a very fast solution for the backbone of modern networks. Today, Ethernet is just as fast or faster thanks to Gigabit Ethernet and 10 Gigabit Ethernet. B, C, and D are incorrect. Ethernet has actually been around longer than FDDI. FDDI is still available, and you can run a version of FDDI on copper, though it is usually called CDDI in that case.
