A DevOps Engineer Is Tasked with Creating a More Stable

question 147

Multiple Choice

A DevOps engineer is tasked with creating a more stable deployment solution for a web application in AWS. Previous deployments have resulted in user-facing bugs, premature user traffic, and inconsistencies between web servers running behind an Application Load Balancer. The current strategy uses AWS CodeCommit to store the code for the application. When developers push to the master branch of the repository, CodeCommit triggers an AWS Lambda deploy function, which invokes an AWS Systems Manager run command to build and deploy the new code to all Amazon EC2 instances. Which combination of actions should be taken to implement a more stable deployment solution? (Choose two.)

• A) Create a pipeline in AWS CodePipeline with CodeCommit as a source provider. Create parallel pipeline stages to build and test the application. Pass the build artifact to AWS CodeDeploy.
• B) Create a pipeline in AWS CodePipeline with CodeCommit as a source provider. Create separate pipeline stages to build and then test the application. Pass the build artifact to AWS CodeDeploy.
• C) Create and use an AWS CodeDeploy application and deployment group to deploy code updates to the EC2 fleet. Select the Application Load Balancer for the deployment group.
• D) Create individual Lambda functions to run all build, test, and deploy actions using AWS CodeDeploy instead of AWS Systems Manager.
• E) Modify the Lambda function to build a single application package to be shared by all instances. Use AWS CodeDeploy instead of AWS Systems Manager to update the code on the EC2 fleet.
