Which two statements about wireless LAN controllers are true? (Choose two.)
Click on the arrows to vote for the correct answer
A. B. C. D. E.AE
A. They can simplify the management and deployment of wireless LANs. Wireless LAN controllers (WLCs) are devices that manage and control access points (APs) in a wireless LAN (WLAN). They simplify the management and deployment of WLANs by providing centralized management of wireless networks, including configuration, monitoring, and troubleshooting of APs. With WLCs, administrators can manage wireless networks from a single console, making it easier to maintain and troubleshoot.
C. They are best suited to smaller wireless networks. Wireless LAN controllers are typically used in larger wireless networks, where managing individual access points can become cumbersome. WLCs provide a centralized management platform, which is especially beneficial in larger networks, making them better suited to managing larger WLANs.
B. They rely on external firewalls for WLAN security. Wireless LAN controllers do not rely on external firewalls for WLAN security. Instead, they have built-in security features, such as wireless intrusion prevention, rogue access point detection, and client authentication. These features help ensure the security and integrity of the WLAN.
D. They must be configured through a GUI over HTTP or HTTPS. Wireless LAN controllers can be configured using either a graphical user interface (GUI) or a command-line interface (CLI). The GUI can be accessed over HTTP or HTTPS, providing a user-friendly interface for managing and configuring the WLC.
E. They can manage mobility policies at a systemwide level. Wireless LAN controllers can manage mobility policies at a systemwide level. This means that administrators can define policies and rules that apply to all access points in the WLAN, providing a consistent and unified user experience. Mobility policies can include things like client roaming, load balancing, and radio resource management.
