What are the plug-ins on the home smart gateway ()? (Multiple choice)

In the context of Huawei's IoT architecture, a smart gateway's software is modular. It includes southbound drivers (A) to communicate with and control various end devices. It uses northbound agents (B) to connect and report data to cloud platforms like Huawei's OceanConnect. It also supports application plugins (D) which are local applications running on the gateway to perform tasks like edge computing, data filtering, or providing specific services. Protocol handling is typically considered part of the driver's function.

C. While the gateway performs protocol translation, in the specific terminology of the HCIA-IoT curriculum, "Protocol plugins" are generally abstracted within the "Driver" component, which handles communication with southbound devices.
