Final answer:
Access points are commonly managed through Telnet/SSH for command line control, USB for direct connections, and built-in web servers for easy browser-based graphical interfaces.
Step-by-step explanation:
Common methods used to configure and manage access points include using Telnet or SSH (Secure Shell), USB (Universal Serial Bus), and a built-in web server for browser-based access. Configuring via Telnet or SSH allows administrators to access the command line interface of the access point over the network for more granular control. The USB method may involve directly connecting to the access point to transfer configurations or update firmware. Lastly, utilizing a built-in web server is a user-friendly way for administrators to configure and manage the device using a web browser; this method usually provides a graphical user interface for easy configuration.
