A DevOps engineer is creating a CI/CD pipeline for an Amazon ECS service.The ECS container instances run behind an Application Load Balancer as the web tier of a three-tier application.An acceptance criterion for a successful deployment is the verification that the web tier can communicate with the database and middleware tiers of the application upon deployment.How can this be accomplished in an automated fashion?Read More →

A DevOps engineer must create a Linux AMI in an automated fashion.The newly created AMI identification must be stored in a location where other build pipelines can access the new identification programmatically.What is the MOST cost-effective way to do this?Read More →

A company’s application is currently deployed to a single AWS Region.Recently, the company opened a new office on a different continent.The users in the new office are experiencing high latency.The company’s application runs on Amazon EC2 instances behind an Application Load Balancer (ALB) and uses AmazonDynamoDB as the database layer.The instances run in an EC2 Auto Scaling group across multiple Availability Zones.A DevOps Engineer is tasked with minimizing application response times and improving availability for users in both Regions.Which combination of actions should be taken to address the latency issues? (Choose three.)Read More →

A company wants to migrate its content sharing web application hosted on Amazon EC2 to a serverless architecture.The company currently deploys changes to its application by creating a new Auto Scaling group of EC2 instances and a new Elastic Load Balancer, and then shifting the traffic away using an Amazon Route53 weighted routing policy.For its new serverless application, the company is planning to use Amazon API Gateway and AWS Lambda.The company will need to update its deployment processes to work with the new application.It will also need to retain the ability to test new features on a small number of users before rolling the features out to the entire user base.Which deployment strategy will meet these requirements?Read More →

A development team manages website deployments using AWS CodeDeploy blue/green deployments.The application is running on Amazon EC2 instances behind an Application Load Balancer in an Auto Scaling group.When deploying a new revision, the team notices the deployment eventually fails, but it takes a long time to fail.After further inspection, the team discovers the AllowTraffic lifecycle event ran for an hour and eventually failed without providing any other information.The team wants to ensure failure notices are delivered more quickly while maintaining application availability even upon failure.Which combination of actions should be taken to meet these requirements? (Choose two.)Read More →

An application is deployed on Amazon EC2 instances running in an Auto Scaling group.During the bootstrapping process, the instances register their private IP addresses with a monitoring system.The monitoring system performs health checks frequently by sending ping requests to those IP addresses and sending alerts if an instance becomes non-responsive.The existing deployment strategy replaces the current EC2 instances with new ones.A DevOps Engineer has noticed that the monitoring system is sending false alarms during a deployment, and is tasked with stopping these false alarms.Which solution will meet these requirements without affecting the current deployment method?Read More →

An online retail company based in the United States plans to expand its operations to Europe and Asia in the next six months.Its product currently runs onAmazon EC2 instances behind an Application Load Balancer.The instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones.All data is stored in an Amazon Aurora database instance.When the product is deployed in multiple regions, the company wants a single product catalog across all regions, but for compliance purposes, its customer information and purchases must be kept in each region.How should the company meet these requirements with the LEAST amount of application changes?Read More →

A company runs an application with an Amazon EC2 and on-premises configuration.A DevOps Engineer needs to standardize patching across both environments.Company policy dictates that patching only happens during non-business hours.Which combination of actions will meet these requirements? (Choose three.)Read More →

A company plans to stop using Amazon EC2 key pairs for SSH access, and instead plans to use AWS Systems Manager Session Manager.To further enhance security, access to Session Manager must take place over a private network only.Which combinations of actions will accomplish this?
