Development with AWS Services III
Explore how to configure event-driven AWS applications using Lambda with retry and dead letter strategies. Understand asynchronous messaging with EventBridge for scalable microservices. Learn caching and storage solutions like ElastiCache and EFS to optimize performance and scalability in cloud environments.
We'll cover the following...
Question 11
A developer is building a serverless application where an Amazon S3 event (e.g., a new object upload) triggers an AWS Lambda function. The Lambda function processes the S3 event and operates. The developer must ensure that if the Lambda function fails during processing, the event is automatically retried twice before being sent to a designated queue for manual inspection.
Which combination of configurations should the developer implement? (Select any two options.)
A. Ensure the Lambda function’s invocation type is set to asynchronous.
B. Enable a Dead Letter Queue (DLQ) on the Lambda function and set the maximum retry attempts. ... ...
