In Huawei campus WLAN solutions, different WLAN architectures are designed to meet varying network scales, cost requirements, and management complexity. The architecture described in this question matches theLeader APsolution.

ALeader APcan operate independently without a dedicated wireless controller, while also having the capability to manage asmall number of subordinate APs. The Leader AP takes on lightweight control functions, such as basic configuration management and simple roaming coordination among the managed APs. This allows wireless users to roam between APs with minimal service interruption, meeting basic mobility requirements.

According to HCIP Datacom Campus Network documentation, the Leader AP architecture is characterized bylow deployment cost and simple maintenance. Since no separate AC is required and the number of APs is limited, network planning and configuration are straightforward. This significantly reduces the technical skill level required for daily operation and maintenance, making it suitable for small campuses, retail stores, branch offices, and small enterprises.

In contrast,Fat APsoperate completely independently and do not support centralized roaming management.AC + Fit AParchitectures are designed for medium to large networks and require higher investment and professional maintenance.Agile distributed APsolutions focus on centralized APs and RUs, which do not align with the independent AP management described.

Therefore, the WLAN architecture that best fits the given characteristics isLeader AP, making optionAthe correct answer.
