In the IoT architecture, which components are endpoints that acquire data for a use case when remotely controlled by mobile apps?

• A. Cloud servers
• B. Mobile phones
• C. IoT devices
• D. IoT gateways

Answer: (C)

The main thing being tested is which component acts as the data-collecting endpoint in an IoT setup. IoT devices are the endpoints that acquire data from the real world—think sensors measuring temperature, humidity, motion, or cameras capturing imagery—and they can also carry out commands issued from a mobile app. These devices can be remotely controlled by mobile applications through a cloud backend or a gateway, which handles communication and sometimes edge processing. Cloud servers provide storage and processing, and mobile phones are the user interface that sends commands and views data. IoT gateways bridge different network protocols and can perform some local processing, but they are not the primary data-collection endpoints. So, the component that best fits “endpoints that acquire data for a use case when remotely controlled by mobile apps” is the IoT device.
