Which type of console port connection requires a rollover cable?

The correct answer for the type of console port connection that requires a rollover cable is the RJ45 connection. A rollover cable, also known as a console cable, is specifically designed to connect a computer's serial port to the console port of a router or switch.

In this context, the RJ45 connection refers to the physical connector used for network interfaces, including console ports on Cisco devices. The rollover cable typically has RJ45 connectors on both ends but is wired in a specific manner where the pinouts are reversed. This allows for the proper communication between the device and the terminal or PC used for configuration.

Understanding this is crucial for network setup and management since Cisco devices commonly use this type of connection for administrative access, allowing network engineers to configure devices directly through the command line interface. Other types of connections listed, like USB and Ethernet, do not require a rollover cable and serve different purposes in networking.
