Which UTP cable connects a pin pair on one end to the opposite pin pair on the other end?

• A. Straight-through cable
• B. Crossover cable
• C. Coaxial cable
• D. Shielded twisted pair cable

Answer: (B)

A crossover cable is designed to connect two similar devices directly by connecting specific pin pairs on one end to the corresponding pairs on the opposite end. For example, it connects the transmit pins of one device to the receive pins of the other. This configuration is essential when connecting devices like switches to switches, or computers to computers, as it allows for proper data transmission between them without requiring additional network equipment, such as a switch or router, to mediate. In contrast, a straight-through cable is used to connect different types of devices, such as a computer to a switch or router. Coaxial cable and shielded twisted pair cable refer to different types of networking cable that have distinct purposes and characteristics but do not adhere to the specific pin-pairing arrangement that a crossover cable implements. Thus, the function and configuration of a crossover cable are what make it the right choice for this question.
