Explanation

With 4 buildings × 75 APs = 300 total APs, the optimal strategy is centralized deployment in the data center with N+1 redundancy. Centralized deployment consolidates all controllers in one location, minimizing per-building rack space and simplifying management (single pane of glass). N+1 redundancy uses one backup controller to cover all N primary controllers - this provides high availability with the fewest total controllers. For example, two 5508 controllers (each handling 150 APs) plus one backup 5508 = 3 total controllers for 300 APs. N+N would double the controller count. The 1+1 model provides less granular redundancy. Distributed deployment (per-building MDF) increases rack space needs, management complexity, and hardware costs.
