Explanation
Huawei DME (Data Management Engine) Storage uses southbound APIs to communicate downward to the devices it directly manages and controls. Fibre Channel switches (B), third-party storage arrays (C), and Huawei storage systems (D) all sit below DME in the management hierarchy, making them the proper targets of southbound API calls that provision, monitor, and control these resources.
Option A is wrong because a third-party cloud management platform sits above DME in the stack, not below it. That platform would interact with DME via northbound APIs, using DME as a managed service rather than being managed by it.
Memory tip: Southbound = south = below = the devices DME controls. Northbound = north = above = the platforms that control DME. When in doubt, ask which direction the management flow travels.
