Why each option

During Layer 2 intercontroller roaming, a wireless client moves between different access points and controllers while maintaining its original IP address and VLAN.

ASSID

The SSID remains the same during roaming to ensure a seamless client experience and maintain the network connection.

BVLAN

Layer 2 roaming implies that the client stays within the same broadcast domain and VLAN, meaning the VLAN does not change.

CIP address

In Layer 2 roaming, the client retains its original IP address because it remains within the same VLAN and subnet.

DAPCorrect

As a client roams across a wireless network, it always connects to a different access point (AP) to maintain connectivity in its new location.

EcontrollerCorrect

Intercontroller roaming specifically means the client transitions its connection from an AP managed by one Wireless LAN Controller (WLC) to an AP managed by a different WLC.
