Which media type is described as broadband coaxial cable carrying multiple baseband channels for a maximum length of 3600 meters at 10 Mbps?

• A. 10BASE-36, 10 Megabit Ethernet, 3600 meters
• B. 10BASE-T, 10 Megabit Ethernet, 100 meters
• C. 100BASE-TX, 100 Megabit Ethernet, 100 meters
• D. 1000BASE-LX, 1 Gigabit Ethernet, 500 meters

Answer: (A)

This question tests knowledge of Ethernet media types and their maximum segment lengths. The description specifies broadband coaxial cable carrying multiple baseband channels for a maximum length of 3600 meters at 10 Mbps. That exactly describes 10BASE-36, an older Ethernet standard that used a broadband coaxial cable to multiplex several baseband channels and could run up to about 3.6 kilometers at 10 Mbps. The other options involve different media and speeds: 10BASE-T uses twisted pair with a 100-meter limit; 100BASE-TX is Fast Ethernet over copper with 100 meters; and 1000BASE-LX is Gigabit Ethernet over fiber with about 500 meters (or more depending on the fiber). So the match is clear: 10BASE-36.
