AWS Certified DevOps Engineer – Professional — Question 126

An application team has three environments for their application: development, pre-production, and production. The team recently adopted AWS CodePipeline. However, the team has had several deployments of misconfigured or nonfunctional development code into the production environment, resulting in user disruption and downtime. The DevOps engineer must review the pipeline and add steps to identify problems with the application before it is deployed.

What should the engineer do to identify functional issues during the deployment process? (Choose two.)

Answer options

• A. Use Amazon Inspector to add a test action to the pipeline. Use the Amazon Inspector Runtime Behavior Analysis Inspector rules package to check that the deployed code complies with company security standards before deploying it to production.
• B. Using AWS CodeBuild to add a test action to the pipeline to replicate common user activities and ensure that the results are as expected before progressing to production deployment.
• C. Create an AWS CodeDeploy action in the pipeline with a deployment configuration that automatically deploys the application code to a limited number of instances. The action then pauses the deployment so that the QA team can review the application functionality. When the review is complete, CodeDeploy resumes and deploys the application to the remaining production Amazon EC2 instances.
• D. After the deployment process is complete, run a testing activity on an Amazon EC2 instance in a different region that accesses the application to simulate user behavior. If unexpected results occur the testing activity sends a warning to an Amazon SNS topic. Subscribe to the topic to get updates.
• E. Add an AWS CodeDeploy action in the pipeline to deploy the latest version of the development code to pre-production Add a manual approval action in the pipeline so that the QA team can test and confirm the expected functionality. After the manual approval action, add a second CodeDeploy action that deploys the approved code to the production environment.

Correct answer: B, E

Explanation

The correct answers B and E focus on proactive measures to ensure application functionality before deployment. Option B uses AWS CodeBuild to simulate user interactions, validating the code's performance, while option E establishes a pre-production environment for thorough testing and a manual approval step to confirm readiness for production. Options A, C, and D do not provide the same proactive testing capabilities within the deployment pipeline, making them less effective for this scenario.
