Which of the following is a true statement concerning the UT

Which of the following is a true statement concerning the UTP cable connection between a PC and a switch?

A. Pin 1 on the PC end is set to receive and is connected to pin 1 on the switch end.

B. Pin 3 on the PC end is set to receive and is connected to pin 3 on the switch end.

C. Pin 1 on the PC end is set to transmit and is connected to pin 3 on the switch end.

D. Pin 3 on the PC end is set to transmit and is connected to pin 1 on the switch end.

E. None of the above.

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.
