A wireless engineer is hired to design a network for six buildings with a WLC in each building to support the access points. Which type of wireless architecture is being used?

A distributed deployment places WLC resources at multiple local sites - one per building in this case - so that APs in each building are managed by a local controller, reducing WAN dependency and keeping client data traffic local to each site rather than backhauling it to a central point.

Autonomous deployment uses standalone APs that require no WLC at all, with each AP managing itself independently without a centralized controller.

Unified deployment is a general term for the Cisco controller-based architecture as a whole and does not specifically describe the per-site controller placement model used here.

Centralized deployment consolidates all WLCs into a single location such as a data center, which is the opposite of distributing one controller per building.
