Which connection can be used to perform the initial configurstion of a router?

The initial configuration of a router can typically be performed using a console connection. This involves connecting a computer or terminal directly to the router's console port using a serial cable. Through this connection, administrators can access the router's command-line interface to set up basic configurations. Alternatively, some routers may also support configuration via a web interface using an Ethernet connection, but the console connection is the most common for initial setups.
