Roll-Over Cables are used to connect a computer to which type of port?

• A. Networking equipment console port
• B. Printer port
• C. USB port
• D. HDMI port

Answer: (A)

Roll-over cables are used for out-of-band management of network devices by connecting a computer to the device’s console port. This serial connection lets you access the device’s command-line interface to configure and troubleshoot routers, switches, and similar equipment. The cable is wired so that the TX and RX lines cross, allowing the computer to communicate with the device’s serial console. The console port on networking gear is typically an RJ-45 jack labeled Console and is not the same as ordinary USB, printer, or display ports. That’s why a roll-over cable isn’t used for USB, HDMI, or printer connections; it’s specifically for accessing the device’s management console. If your PC lacks a serial port, you’d use a USB-to-serial adapter to connect through the console port.
