AWS Lambda
- E
AWS IoT Greengrass
Show answer and explanation
Correct answers: A, C, E
Explanation
To manage IoT devices securely and efficiently, AWS IoT Core provides connectivity and messaging capabilities, AWS IoT Device Management offers features for onboarding and monitoring devices, and AWS IoT Greengrass allows edge computing for IoT devices. These services collectively address the needs of registering, monitoring, and managing IoT devices at scale. Amazon EC2 and AWS Lambda are general-purpose services and are not specifically designed for managing IoT devices.
- A. Correct.
AWS IoT Core is a managed service that allows IoT devices to connect securely to the cloud and interact with AWS services. It is a key service for managing IoT devices.
- B. Incorrect.
Amazon EC2 is a compute service that provides virtual servers in the cloud. While it can be used to build custom IoT solutions, it does not directly manage IoT devices.
- C. Correct.
AWS IoT Device Management is designed to help you onboard, organize, monitor, and manage IoT devices at scale, making it a suitable service for this use case.
- D. Incorrect.
AWS Lambda is a serverless compute service that runs code in response to events. While it can process IoT data, it is not specifically designed for managing IoT devices.
- E. Correct.
AWS IoT Greengrass extends AWS capabilities to edge devices, allowing them to act locally on data they generate. It is a suitable service for managing IoT devices, especially in scenarios requiring edge computing.
