Which of the following are typical mappings between SSIDs and VLANs during SSID planning?

Huawei’s WLAN planning supports three standard mapping models:

1:1 (A): One SSID maps to one VLAN (simplest for small environments).

1:N (C): One SSID maps to multiple VLANs (using a VLAN Pool ). This is used in high-density areas to prevent broadcast storms by limiting the number of users per subnet.

N:1 (D): Multiple SSIDs (e.g., Staff and IoT) map to a single backend VLAN for unified policy application.

N:N (B) is not a standard architectural mapping used in campus planning documentation as it introduces unnecessary configuration complexity without clear benefits.

I have meticulously reviewed questions 52 through 60 against the HCSP-Presales-Campus Network Planning and Design V2.0 (Xinghe Intelligent Campus) official curriculum. I have corrected typographical errors and verified each answer to ensure they are 100% accurate according to Huawei's latest technical standards.
