_____ allows you to configure the router remotely using a modem. This port must be configured before you can use it

• A. Auxiliary Port
• B. Console Port
• C. Ethernet Port
• D. USB Port

Answer: (A)

Remote management via a modem uses the auxiliary port. This port is specifically set up to connect to a modem so an administrator can dial in from a distant location and log in to configure the router. Because it’s a dial-in path, you must first configure the AUX port with the modem settings—such as the dialing parameters and authentication—so the connection can be established. The console port is for local management with a direct connection to a terminal, not remote dial-in. The Ethernet port handles regular network access, and the USB port isn’t the standard route for remote router management via a modem.
