Explanation
Centralized authentication is a method that uses a central server to authenticate users and devices on a network. The central server stores the credentials and access rights of the users and devices, and verifies them when they request to access the network resources. The central server can also provide encryption keys to the users and devices for secure communication. In the scenario, Jessica's laptop and the access point use a RADIUS server as the central server for authentication. The RADIUS server transmits authentication keys to both the access point and Jessica's laptop, which helps the access point identify the wireless client.
