A development team uses AWS CodeCommit, AWS CodePipeline, and AWS CodeBuild to develop and deploy an application.Changes to the code are submitted by pull requests.The development team reviews and merges the pull requests, and then the pipeline builds and tests the application.Over time, the number of pull requests has increased.The pipeline is frequently blocked because of failing tests.To prevent this blockage, the development team wants to run the unit and integration tests on each pull request before it is merged.Which solution will meet these requirements?Read More →

A company uses AWS CodePipeline pipelines to automate releases of its application.A typical pipeline consists of three stages: build, test, and deployment.The company has been using a separate AWS CodeBuild project to run scripts for each stage.However, the company now wants to use AWS CodeDeploy to handle the deployment stage of the pipelines.The company has packaged the application as an RPM package and must deploy the application to a fleet of Amazon EC2 instances.The EC2 instances are in an EC2 Auto Scaling group and are launched from a common AMI.Which combination of steps should a DevOps engineer perform to meet these requirements? (Choose two.)Read More →

A company has a data ingestion application that runs across multiple AWS accounts.The accounts are in an organization in AWS Organizations.The company needs to monitor the application and consolidate access to the application.Currently, the company is running the application on Amazon EC2 instances from several Auto Scaling groups.The EC2 instances have no access to the internet because the data is sensitive.Engineers have deployed the necessary VPC endpoints.The EC2 instances run a custom AMI that is built specifically for the application.To maintain and troubleshoot the application, system administrators need the ability to log in to the EC2 instances.This access must be automated and controlled centrally.The company’s security team must receive a notification whenever the instances are accessed.Which solution will meet these requirements?Read More →

A company wants to use AWS CloudFormation for infrastructure deployment.The company has strict tagging and resource requirements and wants to limit the deployment to two Regions.Developers will need to deploy multiple versions of the same application.Which solution ensures resources are deployed in accordance with company policy?Read More →

The Development team has grown substantially in recent months and so has the number of projects that use separate code repositories.The current process involves configuring AWS CodePipeline manually.There have been service limit alerts regarding the number of Amazon S3 buckets that exist.Which pipeline option will reduce S3 bucket sprawl alerts?Read More →

A company recently migrated its legacy application from on-premises to AWS.The application is hosted on Amazon EC2 instances behind an Application LoadBalancer, which is behind Amazon API Gateway.The company wants to ensure users experience minimal disruptions during any deployment of a new version of the application.The company also wants to ensure it can quickly roll back updates if there is an issue.Which solution will meet these requirements with MINIMAL changes to the application?Read More →

A company has deployed an application on AWS Elastic Beanstalk by using an all-at-once deployment method.The deployment failed recently because of an application misconfiguration and resulted in significant downtime.To prevent such downtime in the future, a DevOps engineer needs to revise the deployment method while maintaining the application performance.The DevOps engineer must ensure that application versions are consistently configured across all instances without creating new environments.Which deployment solution will meet these requirements?Read More →

A DevOps team supports many accounts across an organization in AWS Organizations.The DevOps team has decided to use AWS Coring across the organization to implement centralized automatic remediation of Amazon S3 buckets that have public ACLs.Individual accounts must not be able to modify the remediation strategy.Which solution will meet these requirements?Read More →

A DevOps engineer notices that all Amazon EC2 instances running behind an Application Load Balancer in an Auto Scaling group are failing to respond to user requests.The EC2 instances are also failing target group HTTP health checks.Upon inspection, the engineer notices the application process was not running in any EC2 instances.There are a significant number of out of memory messages in the system logs.The engineer needs to improve the resilience of the application to cope with a potential application memory leak.Monitoring and notifications should be enabled to alert when there is an issue.Which combination of actions will meet these requirements? (Choose two.)Read More →

A company has developed an AWS Lambda function that handles orders received through an API.The company is using AWS CodeDeploy to deploy the Lambda function as the final stage of a CI/CD pipeline.A DevOps Engineer has noticed there are intermittent failures of the ordering API for a few seconds after deployment.After some investigation, the DevOpsEngineer believes the failures are due to database changes not having fully propagated before the Lambda function begins executing.How should the DevOps Engineer overcome this?Read More →
