Yost, Cisco, and console cable are also known as?

• A. Roll-Over Cables
• B. Straight-Through Cables
• C. Crossover Cables
• D. USB Cables

Answer: (A)

The idea being tested is the specific type of serial cable used to reach a device’s management console. This cable is known as a roll-over cable because the pinout on one end is inverted relative to the other end, effectively mirroring the connections. That reversal lets a PC’s serial port talk to a Cisco device’s console port for configuration and management. The terms Yost and Cisco are common historical names for this same cable, and “console cable” is the practical description of its purpose, so all refer to the same roll-over cable. Straight-through and crossover cables are used for regular network data paths (connecting different or similar devices in standard Ethernet roles), not for console access, and USB cables aren’t the standard serial console cable, except when paired with a USB-to-serial adapter.
