Which action occurs during a Layer 3 roam?
During a Layer 3 roam, client traffic is tunneled back to the original controller after the roam occurs. This is because the original controller becomes the anchor controller, and the new controller that the client roams to is treated as the foreign controller. The client maintains its original IP address, and data traffic is tunneled between the new and the original controllers to ensure uninterrupted service. This ensures that the roaming process is transparent to the client.
maybe D is right because , from cisco Layer 3 roaming is similar to Layer 2 roaming in that the controllers exchange mobility messages on the client roam. However, instead of moving the client database entry to the new controller, the original controller marks the client with an “Anchor” entry in its own client database. The database entry is copied to the new controller client database and marked with a “Foreign” entry in the new controller. The roam remains transparent to the wireless client, and the client maintains its original IP address. https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-5/config-guide/b_cg85/overview.html
Answer is D based on the definition of a layer 3 roam from the official cert guide: "A Layer 3 intercontroller roam consists of an extra tunnel that is built between the client’s original controller and the controller it has roamed to. The tunnel carries data to and from the client as if it is still associated with the original controller and IP subnet. Figure 19-9 shows the results of a Layer 3 roam. The original controller (WLC 1) is called the anchor controller, and the controller with the roamed client is called the foreign controller. Think of the client being anchored to the original controller no matter where it roams later. When the client roams away from its anchor, it moves into foreign territory."
Original Controller would have it anchored New Controller would have it listed as foreign.
Answer is C The database entry is copied to the new controller client database and marked with a “Foreign” entry in the new controller. Option B says : as a Foreign in OLD controller , So wrong.
the database entry is copied (not moved) with layer 3 roaming, so, i think the answer C is not correct. "Layer 3 roaming is similar to Layer 2 roaming in that the controllers exchange mobility messages on the client roam.

Answer D
answer is c
I read it wrong, it should be b
B is wrong, the original AP would not label it as "foreign". The NEW AP would mark the client as "foreign"
The correct answer is D
It is a tricky question, in choice C the word "moved" is wrong it should be "copied" because after the client roaming from AP1 to AP2; the database entry in this case copied from WLC1 to WLC2 (All WLC share the same database entry), NOT moved, MOVED meaning is the database of WLC1 became clear. so C is incorrect. The correct answer is D.
after reading this, im going with D https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-5/config-guide/b_cg85/overview.html#:~:text=Layer%203%20roaming%20is%20similar,in%20its%20own%20client%20database.
C is correct

D is the correct answer, Client traffic is tunneled back to the original WLC via CAPWAP Tunnel.
