What is the role of each Wireless LAN Controller (WLC) in wireless networks?

The role of each Wireless LAN Controller (WLC) in wireless networks centers on managing access points (APs) and their configurations. A WLC simplifies and centralizes the administration of multiple access points, ensuring consistent configuration and policies across the entire wireless network.

In practical terms, this management encompasses tasks such as:

• Deploying firmware updates across all APs from a single interface.

• Configuring wireless network settings, including SSIDs, security protocols, and quality of service (QoS) parameters.

• Monitoring network performance and providing troubleshooting capabilities, helping administrators to identify issues related to connectivity, performance, or security.

By leveraging a WLC, network efficiency and security can be significantly enhanced, allowing for more streamlined management and operation as opposed to managing each access point individually.

The other choices presented do not accurately reflect the primary function of a WLC. While some aspects of network infrastructure and management may overlap with other devices or systems, the primary and most critical role of a WLC remains the centralized management of access points.
