B. ITU-T

C. IETF

D. IEEE

E. DoD

2. The network span (maximum distance) of a 1GBaseT network (25 meters) is approximately one tenth (1/100) of the network span of a 10BaseT network (2500 meters) because

A. Higher-speed data signals attenuate (lose power) more quickly, so it cannot be transmitted as far.

B. Both networks have minimum frame sizes and the network spans are tied directly to the minimum frame transmission time to detect collisions.

C. 1GBaseT signals travel 100 times faster (in meters per second) over network cable as compared with 10BaseT signals.

D. 1GBaseT uses higher frequency which has shorter wave length, so the span is shorter.

E. None of the above
