A company manages 500 AWS accounts that are in an organization in AWS Organizations.The company discovers many unattached Amazon Elastic Block Store (Amazon EBS) volumes in all the accounts.The company wants to automatically tag the unattached EBS volumes for investigation.A DevOps engineer needs to deploy an AWS Lambda function to all the AWS accounts.The Lambda function must run every 30 minutes to tag all the EBS volumes that have been unattached for a period of 7 days or more.Which solution will meet these requirements in the MOST operationally efficient manner?Read More →

A space exploration company receives telemetry data from multiple satellites.Small packets of data are received through Amazon API Gateway and are placed directly into an Amazon Simple Queue Service (Amazon SQS) standard queue.A custom application is subscribed to the queue and transforms the data into a standard format.Because of inconsistencies in the data that the satellites produce, the application is occasionally unable to transform the data.In these cases, the messages remain in the SQS queue.A DevOps engineer must develop a solution that retains the failed messages and makes them available to scientists for review and future processing.Which solution will meet these requirements?Read More →

A company is implementing an Amazon Elastic Container Service (Amazon ECS) cluster to run its workload.The company architecture will run multiple ECS services on the cluster.The architecture includes an Application Load Balancer on the front end and uses multiple target groups to route traffic.A DevOps engineer must collect application and access logs.The DevOps engineer then needs to send the logs to an Amazon S3 bucket for near-real-time analysis.Which combination of steps must the DevOps engineer take to meet these requirements? (Choose three.)Read More →

A company has migrated its container-based applications to Amazon EKS and want to establish automated email notifications.The notifications sent to each email address are for specific activities related to EKS components.The solution will include Amazon SNS topics and an AWS Lambda function to evaluate incoming log events and publish messages to the correct SNS topic.Which logging solution will support these requirements?Read More →

A company is using AWS CodePipeline to automate its release pipeline.AWS CodeDeploy is being used in the pipeline to deploy an application to Amazon Elastic Container Service (Amazon ECS) using the blue/green deployment model.The company wants to implement scripts to test the green version of the application before shifting traffic.These scripts will complete in 5 minutes or less.If errors are discovered during these tests, the application must be rolled back.Which strategy will meet these requirements?Read More →

A company has an on-premises application that is written in Go.A DevOps engineer must move the application to AWS.The company’s development team wants to enable blue/green deployments and perform A/B testing.Which solution will meet these requirements?Read More →

A DevOps engineer is working on a data archival project that requires the migration of on-premises data to an Amazon S3 bucket.The DevOps engineer develops a script that incrementally archives on-premises data that is older than 1 month to Amazon S3.Data that is transferred to Amazon S3 is deleted from the on-premises location.The script uses the S3 PutObject operation.During a code review, the DevOps engineer notices that the script does not verify whether the data was successfully copied to Amazon S3.The DevOps engineer must update the script to ensure that data is not corrupted during transmission.The script must use MD5 checksums to verify data integrity before the on-premises data is deleted.Which solutions for the script will meet these requirements? (Choose two.)Read More →

A company uses AWS Key Management Service (AWS KMS) keys and manual key rotation to meet regulatory compliance requirements.The security team wants to be notified when any keys have not been rotated after 90 days.Which solution will accomplish this?Read More →

A company is performing vulnerability scanning for all Amazon EC2 instances across many accounts.The accounts are in an organization in AWS Organizations.Each account’s VPCs are attached to a shared transit gateway.The VPCs send traffic to the internet through a central egress VPC.The company has enabled Amazon Inspector in a delegated administrator account and has enabled scanning for all member accounts.A DevOps engineer discovers that some EC2 instances are listed in the “not scanning” tab in Amazon Inspector.Which combination of actions should the DevOps engineer take to resolve this issue?
