Question :-

An architect is planning an HP Wired-WLAN solution for an office with approximately 4000 users who will use the wireless network rather heavily and also need to roam seamlessly. The solution will have 256 MSM 460 access points (APs). What is one reason for using two Hp Wired-WLAN controllers for this solution?
Each Wired-WLAN controller can only support 128 APs
The customer needs fast roaming, which requires a mobility solution between two controllers
Each Wired-WLAN controller can only support 2000 users
The controller can be licensed and configured to provide redundancy for each other
