A company builds an application that uses an Application Load Balancer in front of Amazon EC2 instances that are in an Auto Scaling group. The application is stateless. The Auto Scaling group uses a custom AMI that is fully prebuilt. The EC2 instances do not have a custom bootstrapping process.
The AMI that the Auto Scaling group uses was recently deleted. The Auto Scaling group's scaling activities show failures because the AMI ID does not exist.
Which combination of steps should a DevOps engineer take to meet these requirements? (Choose three.)

  1. Create a new launch template that uses the new AMI.
  2. Update the Auto Scaling group to use the new launch template.
  3. Reduce the Auto Scaling group's desired capacity to 0.
  4. Increase the Auto Scaling group's desired capacity by 1.
  5. Create a new AMI from a running EC2 instance in the Auto Scaling group.
  6. Create a new AMI by copying the most recent public AMI of the operating system that the EC2 instances use.

Answer(s): A,B,E



A company deploys a web application on Amazon EC2 instances that are behind an Application Load Balancer (ALB). The company stores the application code in an AWS CodeCommit repository. When code is merged to the main branch, an AWS Lambda function invokes an AWS CodeBuild project. The CodeBuild project packages the code, stores the packaged code in AWS CodeArtifact, and invokes AWS Systems Manager Run Command to deploy the packaged code to the EC2 instances.
Previous deployments have resulted in defects, EC2 instances that are not running the latest version of the packaged code, and inconsistencies between instances.
Which combination of actions should a DevOps engineer take to implement a more reliable deployment solution? (Choose two.)

  1. Create a pipeline in AWS CodePipeline that uses the CodeCommit repository as a source provider. Configure pipeline stages that run the CodeBuild project in parallel to build and test the application. In the pipeline, pass the CodeBuild project output artifact to an AWS CodeDeploy action.
  2. Create a pipeline in AWS CodePipeline that uses the CodeCommit repository as a source provider. Create separate pipeline stages that run a CodeBuild project to build and then test the application. In the pipeline, pass the CodeBuild project output artifact to an AWS CodeDeploy action.
  3. Create an AWS CodeDeploy application and a deployment group to deploy the packaged code to the EC2 instances. Configure the ALB for the deployment group.
  4. Create individual Lambda functions that use AWS CodeDeploy instead of Systems Manager to run build, test, and deploy actions.
  5. Create an Amazon S3 bucket. Modify the CodeBuild project to store the packages in the S3 bucket instead of in CodeArtifact. Use deploy actions in CodeDeploy to deploy the artifact to the EC2 instances.

Answer(s): B,C



A company uses an organization in AWS Organizations to manage its AWS accounts. The company's automation account contains a CI/CD pipeline that creates and configures new AWS accounts.
The company has a group of internal service teams that provide services to accounts in the organization. The service teams operate out of a set of services accounts. The service teams want to receive an AWS CloudTrail event in their services accounts when the CreateAccount API call creates a new account.
How should the company share this CloudTrail event with the service accounts?

  1. Create an Amazon EventBridge rule in the automation account to send account creation events to the default event bus in the services accounts. Update the default event bus in the services accounts to allow events from the automation account.
  2. Create a custom Amazon EventBridge event bus in the services accounts. Update the custom event bus to allow events from the automation account. Create an EventBridge rule in the services account that directly listens to CloudTrail events from the automation account.
  3. Create a custom Amazon EventBridge event bus in the automation account and the services accounts. Create an EventBridge rule and policy that connects the custom event buses that are in the automation account and the services accounts.
  4. Create a custom Amazon EventBridge event bus in the automation account. Create an EventBridge rule and policy that connects the custom event bus to the default event buses in the services accounts.

Answer(s): A



A DevOps engineer is building a solution that uses Amazon Simple Queue Service (Amazon SQS) standard queues. The solution also includes an AWS Lambda function and an Amazon DynamoDB table. The Lambda function pulls content from an SQS queue event source and writes the content to the DynamoDB table.
The solution must maximize the scalability of Lambda and must prevent successfully processed SQS messages from being processed multiple times.
Which solution will meet these requirements?

  1. Decrease the batch window to 1 second when configuring the Lambda function's event source mapping.
  2. Decrease the batch size to 1 when configuring the Lambda function's event source mapping.
  3. Include the ReportBatchItemFailures value in the FunctionResponseTypes list in the Lambda function's event source mapping.
  4. Set the queue visibility timeout on the Lambda function's event source mapping to account for invocation throttling of the Lambda function.

Answer(s): C
