CCNA: Cisco Certified Network Associate — Question 462

What provides centralized control of authentication and roaming in an enterprise network?

Answer options

• A. a lightweight access point
• B. a wireless LAN controller
• C. a firewall
• D. a LAN switch

Correct answer: B

Explanation

The correct answer is B, the wireless LAN controller, as it manages the authentication processes and enables seamless roaming for users across the network. Options A, C, and D do not provide centralized control for user authentication and mobility; a lightweight access point requires a controller, a firewall focuses on security, and a LAN switch primarily handles data transfer without authentication management.
