What is a similarity between 1000BASE-LX and 1000BASE-T standards? (CCNA 200-301)
What is a similarity between 1000BASE-LX and 1000BASE-T standards?
A. Both use the same data-link header and trailer formats.
B. Both cable types support RJ-45 connectors.
C. Both support up to 550 meters between nodes.
D. Both cable types support LR connectors.
Solution
Correct answer: A. Both use the same data-link header and trailer formats.
1000BASE-LX and 1000BASE-T are both Ethernet standards that operate at the data link layer and use the same Ethernet frame format, which includes the same data-link header and trailer. However, they differ in terms of the physical medium used, maximum distances, and connector types. 1000BASE-T uses twisted-pair cabling with RJ-45 connectors, while 1000BASE-LX uses fiber optic cabling.
