Roaming between AP Groups and Corporate SSID
Question
AP A is in AP group ONE and AP B in is AP group TWO.
AP group ONE assigns the interface Marketing to the corporate WLAN, whereas AP group TWO assigns the interface Sales to the same WLAN.
What happens if a client roams from AP A to AP B while connected to the corporate SSID?

A. B. C. D. E.D.
In this scenario, the client is connected to the corporate WLAN, and AP A is in AP group ONE, which assigns the interface Marketing to the corporate WLAN. AP B is in AP group TWO, which assigns the interface Sales to the same WLAN. When the client roams from AP A to AP B while connected to the corporate SSID, several things can happen, depending on the network configuration.
A. No roaming is possible: This option is not possible because the client is already connected to the corporate WLAN, and roaming is expected to occur.
B. The client will reconnect with a new IP address from the Sales subnet: This option is possible if the WLAN is configured with different subnets for Marketing and Sales. When the client roams from AP A to AP B, it will need to obtain a new IP address from the Sales subnet, which is assigned to AP group TWO. This can cause a disruption in the connection and may require the client to re-authenticate with the network.
C. The client will keep its Marketing subnet IP address, but roaming will not be seamless: This option is possible if the WLAN is configured with the same subnet for Marketing and Sales. In this case, the client will keep its IP address from the Marketing subnet, but the roaming process may not be seamless. The client may experience a short disruption in the connection and may need to re-authenticate with the network.
D. The client will keep its Marketing subnet IP address, and roaming will be seamless if the appropriate key management is used: This option is possible if the WLAN is configured with the same subnet for Marketing and Sales, and the appropriate key management is used. For example, if the WLAN is configured with WPA2-PSK, the client will be able to roam seamlessly between AP A and AP B while keeping its IP address from the Marketing subnet.
E. A mobility tunnel will be established between the two APs, and the client will be allowed to keep its IP address: This option is possible if the WLAN is configured with a mobility group and the appropriate key management is used. When the client roams from AP A to AP B, a mobility tunnel will be established between the two APs, and the client will be allowed to keep its IP address from the Marketing subnet. This can provide seamless roaming for the client.
In conclusion, the correct answer depends on the network configuration and the key management used for the WLAN. Option D is the most likely answer if the WLAN is configured with the same subnet for Marketing and Sales and the appropriate key management is used. However, if different subnets are used, option B may be the correct answer. Option C is also possible but may not provide seamless roaming. Option E is possible but requires the configuration of a mobility group.
