A law firm is running a web application on AWS. The system manages legal documents uploaded by users, and stores the documents in Amazon S3. Users have complained that file uploads are taking too long and there are timeouts during peak usage. A DevOps engineer found that web servers are managing concurrent uploads and are overloaded. Which actions should be taken to troubleshoot the issue in the MOST cost-effective manner?
A DevOps engineer has automated a web service deployment using AWS CodePipelme with the following steps: • An AWS CodeBuild project compiles the deployment artifact and runs unit tests. • An AWS CodeDeploy deployment group deploys the web service to Amazon EC2 instances in the staging environment. • A CodeDeploy deployment group deploys the web service to EC2 instances in the production environment The quality assurance (QA) team has asked for permission to inspect the build artifact before the deployment to the production environment occurs. The OA team wants to run an internal automated penetration testing tool (invoked using a REST API call) to run some manual tests. Which combination of actions will fulfill this request? (Select TWO.)
A company's application is running on Amazon EC2 instances in an Auto Scaling group. A DevOps engineer needs to ensure there are at least four application servers running at all times. Whenever an update has to be made to the application, the engineer creates a new AMI with the updated configuration and updates the AWS CloudFormation template with the new AMI ID. After the stack update finishes, the engineer manually terminates the old instances one by one. verifying that the new instance is operational before proceeding. The engineer needs to automate this process. Which action will allow for the LEAST number of manual steps moving forward?
A development team manually builds an artifact locally and then places it in an Amazon S3 bucket. The application has a local cache that must be cleared when a deployment occurs. The team executes a command to do this, downloads the artifact from Amazon S3, and unzips the artifact to complete the deployment. A DevOps team wants to migrate to a CI/CD process and build in checks to stop and roll back the deployment when a failure occurs. This requires the team to track the progression ot the deployment. Which combination of actions will accomplish this? (Select THREE.)
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? (Select TWO.)
To run an application, a DevOps Engineer launches an Amazon EC2 instances with public IP addresses in a public subnet. A user data script obtains the application artifacts and installs them on the instances upon launch. A change to the security classification of the application now requires the instances to run wi th no access to the Internet. While the instances launch successfully and show as healthy, the application does not seem to be installed. Which of the following should successfully install the application while complying with the new rule?
