Topic 1 Question 323
A company’s facility has badge readers at every entrance throughout the building. When badges are scanned, the readers send a message over HTTPS to indicate who attempted to access that particular entrance.
A solutions architect must design a system to process these messages from the sensors. The solution must be highly available, and the results must be made available for the company’s security team to analyze.
Which system architecture should the solutions architect recommend?
Launch an Amazon EC2 instance to serve as the HTTPS endpoint and to process the messages. Configure the EC2 instance to save the results to an Amazon S3 bucket.
Create an HTTPS endpoint in Amazon API Gateway. Configure the API Gateway endpoint to invoke an AWS Lambda function to process the messages and save the results to an Amazon DynamoDB table.
Use Amazon Route 53 to direct incoming sensor messages to an AWS Lambda function. Configure the Lambda function to process the messages and save the results to an Amazon DynamoDB table.
Create a gateway VPC endpoint for Amazon S3. Configure a Site-to-Site VPN connection from the facility network to the VPC so that sensor data can be written directly to an S3 bucket by way of the VPC endpoint.

- 正解だと思う選択肢: B
- Option A would not provide high availability. A single EC2 instance is a single point of failure.
- Option B provides a scalable, highly available solution using serverless services. API Gateway and Lambda can scale automatically, and DynamoDB provides a durable data store.
- Option C would expose the Lambda function directly to the public Internet, which is not a recommended architecture. API Gateway provides an abstraction layer and additional features like access control.
- Option D requires configuring a VPN to AWS which adds complexity. It also saves the raw sensor data to S3, rather than processing it and storing the results.

Deploy Amazon API Gateway as an HTTPS endpoint and AWS Lambda to process and save the messages to an Amazon DynamoDB table. This option provides a highly available and scalable solution that can easily handle large amounts of data. It also integrates with other AWS services, making it easier to analyze and visualize the data for the security team.
