Exam 300-425 topic 1 question 201 discussion

B. Round-robin load balancing: ❌ This is not accurate; the load balancing mechanism is more dynamic and based on factors like current load—not a simple round-robin scheme. C. WLAN card driver upgrades: ❌ Upgrading controller code does not require user devices to update their WLAN drivers. This is unrelated to the infrastructure upgrade. D. Anchors with the highest priority: ❌ The selection is not based strictly on priority but depends on the defined primary/secondary configuration and availability.

A and E are the right choices, we can load balance clients between WLCs also designate one WLC as primary and another as secondary

Releases Prior to 8.1 All guest clients are load balanced in round robin fashion amongst anchor WLCs. If an anchor fails, guest clients will be load balanced amongst remaining anchor WLCs. With Release 8.1 All guest clients are sent to anchor controller with highest priority in relation to local internal WLC. If an anchor fails, guest clients will be sent to the next highest priority or round robin if remaining anchors have same priority value.

A+D , 8.1 and higher - clients go to anchor with highest priority, if same priority then load balanced

A and E are correct

Correct Answer A and E A. The foreign controller load balances guest clients across the list of anchor controllers: Upgrading to version 8.10 or later provides the ability for the foreign controller to distribute guest clients across multiple anchor controllers. This helps to optimize network resources and ensures better performance and reliability by preventing any single anchor controller from becoming a bottleneck. Primary and Secondary Anchor Designation: E. The foreign controller designates one anchor as primary and one or more anchors as secondary: With the newer code, the foreign controller can designate a primary anchor controller and one or more secondary anchor controllers. This provides redundancy and ensures that if the primary anchor controller fails, the secondary controllers can take over, thus maintaining service availability for guest clients.
