Question 1

A technician installs and connects some spare switches in a network closet by using crossover cables. Auto-MDI/MDIX is not supported. For some reason, the switches are not communicating with each other. What does the technician note about the configuration while troubleshooting the issue? (Select all that apply.)
A. Transmit occurs on pins 3 and 6 of the switch.
B. The crossover cable uses T568A on both ends.
C. Transmit occurs on pins 1 and 2 of the switch.
D. The crossover cable uses T568A on one end and T568B on the other end.

Answer 1

A. Transmit occurs on pins 3 and 6 of the switch.
