Topic 1 Question 991
A company uses GPS trackers to document the migration patterns of thousands of sea turtles. The trackers check every 5 minutes to see if a turtle has moved more than 100 yards (91.4 meters). If a turtle has moved, its tracker sends the new coordinates to a web application running on three Amazon EC2 instances that are in multiple Availability Zones in one AWS Region.
Recently, the web application was overwhelmed while processing an unexpected volume of tracker data. Data was lost with no way to replay the events. A solutions architect must prevent this problem from happening again and needs a solution with the least operational overhead.
What should the solutions architect do to meet these requirements?
Create an Amazon S3 bucket to store the data. Configure the application to scan for new data in the bucket for processing.
Create an Amazon API Gateway endpoint to handle transmitted location coordinates. Use an AWS Lambda function to process each item concurrently.
Create an Amazon Simple Queue Service (Amazon SQS) queue to store the incoming data. Configure the application to poll for new messages for processing.
Create an Amazon DynamoDB table to store transmitted location coordinates. Configure the application to query the table for new data for processing. Use TTL to remove data that has been processed.

Answer: C Amazon SQS provides a reliable and scalable way to decouple the components of the application. By using a queue, the incoming tracker data can be buffered, ensuring that if the web application is overwhelmed with data, the messages will still be retained in the queue until they can be processed.

The correct Answer is C. Amazon SQS is a fully managed message queuing service that allows you to decouple and scale applications by buffering the incoming data. This would ensure that data is stored in a reliable, scalable queue until the web application is ready to process it. SQS provides high availability and fault tolerance, and guarantees that no data will be lost, as the messages remain in the queue until they are processed. The web application can poll the SQS queue for new messages and process them at its own pace, preventing the application from being overwhelmed by large volumes of tracker data. Operational overhead is minimal because SQS is a fully managed service. The application only needs to poll the queue for messages, and there is no need to manage infrastructure.
