An engineer has deployed a WLAN in a high-density auditorium and expects the number of clients to grow. Which WLC configuration can be used increase the IP space without any service disruptions?

RF groups manage radio resource coordination between WLCs and have no effect on DHCP scope size or the number of available IP addresses.

An interface group associates multiple dynamic interfaces, each backed by its own DHCP scope, with a single WLAN. A new dynamic interface and DHCP pool can be created and added to the existing interface group without taking the WLAN offline or affecting connected clients. This makes interface groups the correct tool for non-disruptively scaling IP capacity in high-density environments.

A single dynamic interface is bound to one VLAN and one DHCP scope; replacing or resizing it requires reconfiguring the WLAN, which causes a service disruption.

AP groups determine which WLANs are advertised by which APs and do not influence DHCP pool capacity or IP address availability.
