Explanation

The correct interaction identifies the core functional tasks required for an automated quality detection, product removal, and cloud reporting system, leveraging sensor and cloud SDKs.

Approach. The scenario describes an application that captures data from a sensor, performs quality checks, activates automation for product removal, and reports to the cloud using an SDK. Based on this, the following options must be selected and dragged to the right panel:

1. 'code function for detection': The application needs to 'calculate if the product meets a determined quality specification,' which necessitates coding logic to perform this detection.
2. 'quality specification of product': To perform the detection, the specific quality standards or 'specification' must be defined and available to the detection function. This is a critical prerequisite 'task' or definition that must be 'completed' for the system to work.
3. 'sensor function with sensor SDK': Data is 'captured from an application that is connected to a sensor.' Interacting with the sensor to acquire data will require implementing a 'sensor function' often utilizing a 'sensor SDK'.
4. 'cloud function communication with cloud SDK': The application needs to 'report detailed results back to the cloud' and explicitly states 'Using the SDK of the cloud provider'. This means communication with cloud services will be a core 'task' implemented via the 'cloud SDK'.
5. 'product removal function': The application needs to 'activate an automation to remove poor quality products.' This direct requirement implies a 'product removal function' must be implemented to trigger or manage this automation.

Common mistakes.

• common_mistake. Leaving 'credentials for network and cloud operations' on the left side is correct because while credentials are essential for authentication and authorization, they are typically a configuration item or an input to an SDK call, not a 'task' or 'function' that is implemented directly by the application developer in the same sense as the others. The question asks for 'tasks that must be completed'. Similarly, 'user interaction with the application' is correctly left out because the scenario emphasizes automation ('activate an automation to remove poor quality products') and the core functions of detection, removal, and reporting, none of which explicitly require or imply direct user interaction as a core 'task' to be implemented for this specific problem statement. A common mistake would be to drag credentials because they are necessary for operations, overlooking the distinction between a 'task' or 'function' and a configuration requirement.

Concept tested. This question tests the understanding of an end-to-end IoT/edge solution architecture, including data acquisition from sensors, local processing/decision-making, automation/actuation, and cloud integration. It also assesses the ability to differentiate between core functional tasks/components, necessary configuration elements (like credentials), and non-essential features (like user interaction for this specific automated scenario). The role of SDKs for specific hardware (sensors) and cloud platforms is also implied.
