Why would a network administrator use a WLAN controller?

• A. To facilitate group configuration and management of multiple WLANs through a WLC
• B. To enhance the security of the WLAN connections
• C. To increase the transmission power of individual access points
• D. To decrease latency in the wireless network

Answer: (A)

A WLAN controller is primarily used to manage and configure multiple wireless access points within a network. By centralizing the management through a Wireless LAN Controller (WLC), network administrators can streamline the configuration and enforcement of policies across all access points in a network. This group management capability simplifies tasks such as firmware upgrades, security settings, and additional network policies, ensuring consistency and reducing the administrative burden. While enhancing security and potentially influencing latency can be aspects of a WLAN's functionality, they are not the primary reasons for employing a WLAN controller. Security measures are typically handled by protocols and configurations rather than the controller itself, and latency reduction is more dependent on network design and traffic management rather than solely the presence of a controller. Increasing transmission power falls within the capabilities of individual access points rather than the controller’s direct function.
