The station to hub distance in which it is 2000 metres.

  • A.100 Base-Tx
  • B.100 Base-Fx
  • C.100 Base-T4
  • D.100 Base-T1

Answer: B

A station-to-hub distance of 2000 metres is possible with 100 Base-Fx.

100 Base-FX is Fast Ethernet over two strands of multimode optical fibre, and full duplex links can run up to 2000 metres. 100 Base-TX and 100 Base-T4 run on twisted pair copper (two pairs of category 5, and four pairs of category 3) and are limited to about 100 metres. There is no standard called 100 Base-T1 for this purpose.
