As part of an IoT solution, you have to deploy image recognition logic to certain field devices, in order to complete computation-intensive tasks locally. The devices are already registered in the IoT Hub as edge devices. Your task is to go on with their configuration and deploying the logic. 
Which software component of the edge device should you use to accommodate the logic?

Answer options:

A.IoT Edge module
B.IoT Edge hub
C.IoT Edge agent
D.IoT Edge runtime

Correct Answer: A
Option A is CORRECT because the executable packages to be deployed on edge devices are implemented as containers. These containerized logics deployed on the device are the IoT Edge modules.
Option B is incorrect because, being a part of the IoT Edge runtime, the task of the IoT Edge hub is to manage the communication between the modules.
Option C is incorrect because the IoT Edge agent is responsible for the deployment and monitoring of the modules. It is a part of the IoT Edge runtime.
Option D is incorrect because IoT Edge hub, IoT Edge agent and IoT Edge security daemon together make up the IoT Edge runtime.
