A. B. C. D.A.
A. The correct answer is A, "It eliminates the need to configure each access point individually."
A Cisco Wireless LAN Controller (WLC) provides centralized management for a network of wireless access points (APs). Instead of individually configuring each AP, the WLC allows for simplified management and configuration of multiple APs from a single console. This results in significant time and cost savings for network administrators.
B. Answer B, "Central AP management requires more complex configurations," is incorrect. In fact, central AP management simplifies configurations by allowing administrators to configure APs from a single location.
C. Answer C, "Unique SSIDs cannot use the same authentication method," is incorrect. The WLC allows for multiple SSIDs, each with their own authentication method.
D. Answer D, "It supports autonomous and lightweight APs," is partially correct. A WLC supports lightweight APs, which have reduced functionality and rely on the WLC for most functions. Autonomous APs, on the other hand, have their own built-in management and configuration capabilities and do not require a WLC. However, as autonomous APs cannot benefit from centralized management and configuration, they are not commonly used in enterprise wireless networks.
