Multiple Choice

The concept of an ESS describes:

ESS stands for Extended Service Set. It describes a wireless LAN setup that uses multiple access points all sharing the same SSID, connected through a common wired backbone, so devices can roam between APs without dropping the connection. Each AP creates its own basic service area, but the network presents a single SSID to users, allowing seamless handoff as you move around. This contrasts with a single AP serving a network, which doesn’t support roaming across multiple APs. A wired Ethernet switch alone isn’t about roaming between APs, and a cloud-managed WLAN refers to how the network is managed, not the roaming capability itself.
