Which ports can be used to connect devices to a switch?

• A. Only straight-through UTP cables
• B. Only crossover UTP cables
• C. Rollover, straight-through, and crossover
• D. Only fiber optic cables

Answer: (C)

The correct choice encompasses various cable types that facilitate connectivity in a network. Rollover, straight-through, and crossover cables can all be used to connect devices to a switch, albeit in different scenarios. Straight-through cables are most commonly used to connect devices of different types, such as a computer to a switch or a switch to a router. They have the same wiring on both ends, making them ideal for this type of connection. Crossover cables are used for connecting similar devices directly, such as switch to switch or computer to computer. The wiring is arranged differently on each end, allowing the transmitting pins on one end to connect with the receiving pins on the other. Rollover cables, while less common in practice, can connect a computer (specifically a console terminal) to a router or switch's console port for management purposes. This type is largely used for configuration and management rather than normal data traffic. Thus, the inclusion of all three types in the correct answer highlights their utility in providing various connection scenarios based on the devices being interconnected.
