NEW QUESTION # 141
Which statement is correct regarding the classification of roaming?
- A. Layer 2 roaming: When a user moves between APs, the terminal signal connects from the old AP to the new AP, which is roaming. The service VLAN of the AP remains unchanged before and after roaming, and the corresponding gateway remains unchanged.
- B. Sometimes, a network situation arises where two subnets share the same VLAN ID, but belong to different subnets. To prevent the system from misidentifying inter-subnet roaming as Layer 2 roaming based solely on the VLAN ID, the roaming domain is used to determine whether the devices are within the same subnet. Only when the VLANs and roaming domains are the same does Layer 2 roaming occur; otherwise, it is Layer 3 roaming.
- C. Layer 3 roaming: The service VLANs of the SSIDs before and after roaming are different. The service networks provided by the APs are different Layer 3 networks, corresponding to different gateways. In this case, to maintain the unchanged IP address of the roaming user, it is necessary to migrate the user traffic back to the API of the initial access network segment to achieve cross-VLAN roaming.
Answer: A,B,C
