The correct answer is B. Connect a second 10-GB interface on the WLC and implement LAG. The Cisco 5520 WLC supports Link Aggregation (LAG), which allows multiple physical interfaces to be treated as a single logical channel.

Question
A customer uses a Cisco 5520 WLC that is connected via a single 10-GB interface to manage the wireless network. The wireless network includes 500 APs for the campus network. The customer wants to add 300 APs and is concerned about traffic load and lack of redundancy. The purchase of a second controller is not an option. Which design approach mitigates the customer concerns?
Options
- AConnect a second 10-GB interface on the WLC and set the port as a secondary port.
- BConnect a second 10-GB interface on the WLC and implement LAG.
- CImplement a vWLC and configure SSO with the WLC.
- DImplement a vWLC and configure N+1 redundancy with the WLC.

Explanation
The Cisco 5520 WLC supports Link Aggregation (LAG), which allows multiple physical interfaces to be treated as a single logical channel. By connecting a second 10-GB interface and implementing LAG, the customer can increase the throughput capacity and provide redundancy without the need for a second controller. This approach also simplifies network design and management by reducing the number of IP addresses needed for the controllers and APs.
