Which port is commonly used to connect a management console to a router?

• A. Console Port
• B. Auxiliary Port
• C. Network Interfaces
• D. Power Port

Answer: (A)

Connecting to a router’s management interface is done through the console port. This dedicated port is designed for local configuration, monitoring, and troubleshooting, providing a direct serial path to the device even when the network isn’t up. It’s what technicians use during initial setup or when recovering a device, using a terminal program on a computer. The other ports serve different roles: network interfaces carry data traffic, not management access; the auxiliary port is typically for an out-of-band dial-in connection via modem, which is less common for everyday management; and the power port simply supplies power.
