A. B. C. D.A.
A secondary WLC (Wireless LAN Controller) is a backup controller that takes over the control of the APs (Access Points) in the event of a failure of the primary controller. The primary WLC is responsible for managing and controlling the APs, while the secondary WLC acts as a standby controller, ready to take over the control if the primary WLC fails.
Option B is correct because one of the primary responsibilities of a secondary WLC is to register the LAPs (Lightweight Access Points) if the primary controller fails. When the APs lose their connection to the primary controller, they will automatically try to connect to the secondary controller, and the secondary WLC will take over the control of the APs. The secondary WLC will register the LAPs and will continue to manage them until the primary controller becomes available again.
Option A is incorrect because Layer 2 and Layer 3 roaming between controllers is handled by the Mobility Group, which is a collection of WLCs that work together to provide seamless mobility and roaming between wireless networks. The Mobility Group enables clients to roam between controllers without losing their connection or experiencing any interruption in service.
Option C is incorrect because the load balancing of LAPs is not the responsibility of the secondary WLC. The primary WLC is responsible for managing the APs and balancing the load across them. However, the secondary WLC can assist in load balancing by taking over the control of some of the APs in the event of a failure of the primary controller.
Option D is incorrect because the traffic load balancing is not the responsibility of the secondary WLC. The primary WLC is responsible for managing the APs and balancing the traffic load across them. However, the secondary WLC can assist in traffic load balancing by taking over the control of some of the APs in the event of a failure of the primary controller.
