An engineer must implement Cisco Identity-Based Networking Services at a remote site using ISE to dynamically assign groups of users to specific IP subnets.
If the subnet assigned to a client is available at the remote site, then traffic must be offloaded locally, and subnets are unavailable at the remote site must be tunneled back to the WLC.
Which feature meets these requirements?

A. B. C. D.C.
The feature that meets the given requirements is FlexConnect local authentication, which enables local switching and local authentication for clients at remote sites.
FlexConnect is a feature of Cisco wireless LAN controllers (WLCs) that enables local switching and local authentication for clients at remote sites. It allows traffic to be offloaded locally at the remote site when the client's assigned IP subnet is available there, and it tunnels traffic back to the WLC when the subnet is unavailable. This ensures that clients receive the appropriate services regardless of their location.
In this scenario, Cisco Identity-Based Networking Services (IBNS) is being implemented to dynamically assign groups of users to specific IP subnets. This means that users will be assigned to specific subnets based on their identity, such as their role or department within the organization. FlexConnect local authentication will allow these users to be authenticated and authorized locally at the remote site, while also allowing traffic to be offloaded locally if the appropriate subnet is available.
The other answer options are not relevant to the given requirements. "Learn client IP address" is not a feature or capability of Cisco wireless networks. VLAN-based central switching is a feature that enables central switching of client traffic based on VLAN tags, but it does not address the requirement for local switching at remote sites. Central DHCP processing is a feature that enables the WLC to act as a DHCP server for clients, but it does not address the requirement for local authentication or offloading of traffic at remote sites.
