Question

An image-processing company has a web application that users use to upload images. The application uploads the images into an Amazon S3 bucket. The company has set up S3 event notifications to publish the object creation events to an Amazon Simple Queue Service (Amazon SQS) standard queue. The SQS queue serves as the event source for an AWS Lambda function that processes the images and sends the results to users through email. Users report that they are receiving multiple email messages for every uploaded image. A solutions architect determines that SQS messages are invoking the Lambda function more than once, resulting in multiple email messages. What should the solutions architect do to resolve this issue with the LEAST operational overhead?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Increase the visibility timeout in the SQS queue to a value that is greater than the total of the function timeout and the batch window timeout. AWS Batch schedules and runs batch computing jobs at any scale without managing clusters. Amazon SQS is a fully managed message queue that decouples components and absorbs traffic spikes.
