An Extended Service Set (ESS) is the correct configuration for this scenario as it involves multiple access points across a larger coverage area such as a campus. ESS allows users to roam seamlessly between access points without losing connection, assuming all access points are configured under the same SSID and security settings. In contrast, a BSS (Basic Service Set) is a single access point defining a single wireless network, IBSS (Independent Basic Service Set) is an ad hoc network without an access point, and SSID does not refer to a network architecture but rather to the network name itself.
