A company wants to implement a continuous integration for its workloads on AWS. The company wants to trigger unit test in its pipeline for commits-on its code repository, and wants to be notified of failure events in the pipeline. How can these requirements be met? A. Store the source code in AWS CodeCommit. Create a CodePipeline to automate unit testing. Use Amazon SNS to trigger notifications ..

An application stores images in an S3 bucket. Amazon S3 event notifications are used to trigger a Lambda function that resizes the images. Processing each image takes less than a second. How will AWS Lambda handle the additional traffic? A. Lambda will scale out to execute the requests concurrently. B. Lambda will handle the requests sequentially in the order received. C.

Which AWS Service can help refactor and manage the state machine? A. AWS Data Pipeline B. AWS SNS with AWS SQS C. Amazon Elastic MapReduce D. AWS Step Functions 현재의 아키텍처는 대형 상태 기계로서 서로를 호출하는 많은 람다 기능을 사용한다. 이 상태 기계의 조정은 쉽게..

A Developer has implemented a Lambda function that needs to add new customers to an RDS database that is expected to run hundreds of times per hour. The Lambda function is configured to use 512MB of RAM and is based on the following pseudo code: After testing the Lambda function, the Developer notices that the Lambda execution time is much longer than expected. What should the Developer do to im..

An application takes 40 seconds to process instructions received in an Amazon SQS message. Assuming the SQS queue is configured with the default VisibilityTimeout value, what is the BEST way, upon receiving a message, to ensure that no other instances can retrieve a message that has already been processed or is currently being processed? A. Use the ChangeMessageVisibility API to increase the Vis..
