What is a function of Wireless LAN Controller?
Click on the arrows to vote for the correct answerA. B. C. D.
A Wireless LAN Controller (WLC) is a network device that is responsible for managing and controlling wireless access points (APs) within a wireless local area network (WLAN). The primary function of a WLC is to provide centralized management and control of all wireless traffic in the network.
Option A: Register with a single access point that controls traffic between wired and wireless endpoints This answer is incorrect because a WLC does not register with a single access point. Instead, the WLC is responsible for managing and controlling multiple access points in a WLAN.
Option B: Use SSIDs to distinguish between wireless clients This answer is incorrect because the function of distinguishing between wireless clients is performed by the access points, not the WLC. The WLC does not use SSIDs to distinguish between wireless clients.
Option C: Send LWAPP packets to access points This answer is partially correct. A WLC sends Lightweight Access Point Protocol (LWAPP) packets to access points to manage and control them. LWAPP is a protocol used to control and manage wireless APs.
Option D: Monitor activity on wireless and wired LANs This answer is correct. One of the primary functions of a WLC is to monitor the activity on both wired and wireless LANs. The WLC monitors network performance, identifies network issues, and provides real-time alerts when issues arise.
In summary, the correct answer is D.
