Which cable type would you use to connect a switch to a switch?
Answer Options
Straight-through cable
Crossover cable
Rolled cable
Shielded cable
Correct Answer: B
Explanation
You would use a crossover cable because a switch is a data communications equipment (DCE) Ethernet device. When connecting a DCE Ethernet device to another DCE Ethernet device, you would need to cross the connection with a crossover cable. Newer switches have medium dependent interface-crossover (MDI-X) capabilities to detect the need for a crossover cable and will automatically switch the cable over if a straight-through cable is used. A straight-through cable is used to connect a DCE Ethernet device such as a switch to data terminal equipment (DTE) such as a host. A rolled cable is used for serial communication between a router or switch and a modem or serial adapter for configuration. A shielded cable has either a metal webbed shield or foil shield to filter out electrical magnetic interference (EMI).
