Different Types of Roaming in Cisco Wireless Networks

D.

The type of roam that occurs in this scenario is intra-controller roam.

Roaming is the process by which a wireless client moves from one access point to another while maintaining network connectivity. In this scenario, the client device is moving between access points located on different floors in an atrium. The access points are joined to the same controller and configured in local mode.

Local mode is a deployment model in which the access points are managed by a wireless LAN controller (WLC). In local mode, the access points send all client traffic to the WLC, which forwards it to the appropriate destination. The access points are in different AP groups and have different IP addresses, but the client VLAN in the groups is the same.

An AP group is a collection of access points that share the same configuration. Access points can belong to multiple AP groups, but they can only have one active AP group at a time. In this scenario, the access points are in different AP groups but have the same client VLAN.

Intra-controller roam occurs when a wireless client moves between access points that are managed by the same wireless LAN controller. In this scenario, since the access points are joined to the same controller and configured in local mode, the client device will perform an intra-controller roam when it moves between the access points.

Inter-controller roam occurs when a wireless client moves between access points that are managed by different wireless LAN controllers. Inter-subnet roam occurs when a wireless client moves between access points that are on different IP subnets. Intra-VLAN roam occurs when a wireless client moves between access points on the same VLAN.

Therefore, the correct answer to the question is option D, intra-controller roam.
