200-901 Question 181
Select 3You are developing an IoT solution that requires communication between devices in a local network and a cloud-based service. To ensure proper communication, you need to configure a gateway. Which of the following statements are true about the role of the gateway in this scenario?
- A
The gateway acts as a bridge between the local network and the cloud service.
- B
The gateway is responsible for authenticating devices on the local network before allowing communication.
- C
The gateway is only responsible for routing traffic within the local network.
- D
The gateway can perform data processing and filtering before sending data to the cloud.
- E
The gateway replaces the need for application programming interfaces (APIs) to communicate with the cloud.
Show answer and explanation
Correct answers: A, B, D
Explanation
In IoT architectures, gateways play a critical role in bridging the gap between local devices and cloud-based services. They ensure secure communication, provide data processing capabilities, and enable seamless integration with external platforms. However, gateways complement APIs rather than replacing them, as APIs are necessary for structured communication between systems.
- A. Correct.
Correct: A gateway serves as a bridge between the local network and the cloud, enabling communication between devices and cloud-based services.
- B. Correct.
Correct: Gateways often include security features such as device authentication to ensure only trusted devices communicate with the cloud.
- C. Incorrect.
Incorrect: While gateways can route traffic, their role is not limited to routing within the local network. They also facilitate communication to external systems like the cloud.
- D. Correct.
Correct: Gateways often include edge computing capabilities, which allow them to perform data processing and filtering locally before transmitting data to the cloud to reduce latency and bandwidth usage.
- E. Incorrect.
Incorrect: Gateways do not replace APIs; rather, they work in conjunction with APIs to facilitate communication between systems.
