Why would a network administrator use RADIUS servers on a WLAN?

• A. To improve bandwidth for the network
• B. To restrict access to the WLAN to authorized, authenticated users only
• C. To manage DHCP assignments on the network
• D. To enhance the quality of service on wireless connections

Answer: (B)

Using RADIUS servers on a WLAN primarily serves the function of restricting access to the network to authorized, authenticated users only. RADIUS, which stands for Remote Authentication Dial-In User Service, is a protocol designed for network authentication. It provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service. When a user attempts to join a WLAN, the RADIUS server checks the user's credentials against a database of authorized users. If the credentials are valid, the user is granted access to the network. This process ensures that only those who are permitted can connect, significantly enhancing the security of the wireless network. In contrast, the other options do not accurately represent the primary role of RADIUS servers in a WLAN context. While bandwidth, DHCP assignments, and quality of service are important considerations in network management, they are not the primary functions of RADIUS servers. RADIUS focuses fundamentally on managing user authentication, making option B the most suitable answer.
