An administrator is wiring some Cat 5 cable into a serial cable. Which of the following wiring types should the administrator use?

A rollover cable reverses every pin end to end (pin 1 maps to pin 8, pin 2 to pin 7, etc.) and is the standard wiring used for out-of-band serial console access to Cisco routers and switches. When an administrator converts Cat 5 into a serial cable for console connectivity, rollover wiring is the required standard for that interface type.

A crossover cable swaps transmit and receive pairs and is used to connect two similar network devices such as switch to switch, not for serial console connections.

Using EIA 568A on both ends produces a straight-through cable under the 568A standard, which is for connecting unlike devices on a LAN, not for serial console access.

A straight-through cable (568A on one end, 568B on the other) is used to connect a host to a switch or hub and has no application in a serial console connection.
