Which of the following connectors provides console access to a switch?
Correct Answer: B
* Console Access: * Purpose: Console access to a switch allows administrators to configure and manage the device directly. This is typically done using a terminal emulator program on a computer. * RJ45 Connector: * Common Use: The RJ45 connector is widely used for Ethernet cables and also for console connections to network devices like switches and routers. * Console Cables: Console cables often have an RJ45 connector on one end (for the switch) and a DB9 serial connector on the other end (for the computer). * Comparison with Other Connectors: * ST (Straight Tip): A fiber optic connector used for networking, not for console access. * BNC (Bayonet Neill-Concelman): A connector used for coaxial cable, typically in older network setups and not for console access. * SFP (Small Form-factor Pluggable): A modular transceiver used for network interfaces, not for console access. * Practical Application: * Connection Process: Connect the RJ45 end of the console cable to the console port of the switch. Connect the DB9 end (or USB via adapter) to the computer. Use a terminal emulator (e.g., PuTTY, Tera Term) to access the switch's command-line interface (CLI). References: * CompTIA Network+ study materials on network devices and connectors.
