A network designer is asked to recommend a media type. The customer desires a Fast Ethernet network, but wishes to keep costs at a minimum. Which of the following media types should be recommended?

A. Cat3 UTP

B. Cat5 UTP

C. SMF

D. MMF

Solution

E is correct. NIC pinouts have pins 1 and 2 set to transmit, and 3 and 6 set to receive. Since both devices have different pinouts, a straight-through (pin 1 to 1, 2 to 2, and so on) cable would be used.

A, B, C, and D are incorrect. A and B are incorrect because pin 1 on the PC NIC is set to transmit, not receive. C and D are incorrect because the pinouts listed indicate a crossover cable.
