Question
Which action occurs during a Layer 3 roam?
A. The client receives a new IP address after authentication occurs.
B. The client is marked as “Foreign” on the original controller.
C. The client database entry is moved from the old controller to the new controller.
D. Client traffic is tunneled back to the original controller after a Layer 3 roam occurs.
Answer
D. Client traffic is tunneled back to the original controller after a Layer 3 roam occurs.
Explanation
In a Layer 3 roam, the client moves between access points that are on different subnets. To maintain the client’s connection and allow it to continue accessing the network without interruption, the client’s traffic is tunneled back to the original controller where it first connected. This is done to ensure that the client can still access the original network after roaming15. The client does not receive a new IP address after authentication, and the client database entry is not moved from the old controller to the new controller.
