The correct answer is A. It minimizes inter-controller roaming of clients. Placing all APs in each building on a dedicated WLC keeps client roaming within each building as intra-controller roaming, which minimizes the slower and more complex inter-controller roaming events.
Question
An engineer has deployed two Cisco 2504 WLCs to support the wireless network in two newly added buildings on a campus. The engineer puts 70 APs in the first building on one WLC and 70 APs in the second building on the other Cisco 2504 WLC. Which result does this design achieve?
Options
- AIt minimizes inter-controller roaming of clients.
- BIn ensures that the number of clients does not exceed the maximum limit of 70 on Cisco 2504
- CIt minimizes intra-controller roaming of clients.
- DIn ensures that the number of APs does not exceed the maximum limit of 70 on Cisco 2504

Why each option
Placing all APs in each building on a dedicated WLC keeps client roaming within each building as intra-controller roaming, which minimizes the slower and more complex inter-controller roaming events.
When all APs in Building 1 are on WLC1 and all APs in Building 2 are on WLC2, clients moving between APs within the same building perform intra-controller roaming, which is handled locally and is seamless. Inter-controller roaming is minimized because clients would only cross controller boundaries when physically moving between the two buildings, which is a rare event.
The Cisco 2504 WLC supports a maximum of 75 APs, not 70, so the stated maximum limit of 70 is factually incorrect.
Concentrating all building APs on one WLC actually maximizes intra-controller roaming within that building rather than minimizing it.
The Cisco 2504 WLC maximum AP limit is 75, not 70, making this statement factually incorrect about the platform's capacity.
