Which of the following devices can be managed through the southbound APIs of DME Storage?

Question

Options

• AThird-party cloud management platform
• BFibre Channel Switch
• CThirdparty storage
• DHuawei storage

• A
  16% (9)
• B
  84% (46)

Explanation

DME (Data Management Engine) Storage uses southbound APIs to communicate with and manage the devices that sit below it in the management hierarchy. Fibre Channel Switches (B), third-party storage (C), and Huawei storage (D) are all infrastructure-layer devices that DME Storage directly administers through these downward-facing interfaces, enabling unified management of heterogeneous storage environments.

Option A is incorrect because a third-party cloud management platform sits above DME Storage in the hierarchy and would interact with DME through its northbound APIs, not the other way around. In management architecture, northbound APIs serve upper-layer systems that consume or orchestrate DME, while southbound APIs reach down to managed resources.

Memory tip: Think of "south" as "down the stack." Southbound APIs go down to the devices DME controls. Northbound APIs go up to the systems that control DME. A cloud management platform is a controller, so it belongs on the northbound (north = up) side.
