Question 1

A company has deployed an application on AWS Elastic Beanstalk. The company has configured the AutoScaling group that is associated with the Elastic Beanstalk environment to have five Amazon EC2 instances.If the capacity is fewer than four EC2 instances during the deployment, application performance degrades.The company is using the all-at-once deployment policy.What is the MOST cost-effective way to solve the deployment issue?

A : Change the Auto Scaling group to six desired instances.

B : Change the deployment policy to traffic splitting. Specify an evaluation time of 1 hour.

C : Change the deployment policy to rolling with additional batch. Specify a batch size of 1.

D : Change the deployment policy to rolling. Specify a batch size of 2.

Answer: C

Question 2

A company has a serverless application that uses Amazon API Gateway and AWS Lambda functions to expose a RESTful API. The company uses a continuous integration and continuous delivery (CI/CD) workflow to deploy the application to multiple environments. The company wants to implement automated integration tests after deployment. A developer needs to set up the necessary infrastructure and processes to automate the deployment and integration tests for the serverless application.

A : Configure API Gateway stages to represent each application environment. Use AWS SAM templates to manage the infrastructure for the Lambda functions and API resources. Use AWS CodeBuild to implement automated deployment tests to validate the deployments in each stage.

B : Configure API Gateway stages to represent each application environment. Use AWS CloudFormation to manage the infrastructure for the Lambda functions and API resources. Use AWS CodeBuild to implement automated deployment tests to validate the deployments in each stage.

C : Use AWS CodePipeline to create a CI/CD pipeline. Configure API Gateway stages to represent each application environment. Use AWS CloudFormation templates to manage the infrastructure for the Lambda functions and API resources. Use AWS CodeBuild to implement automated deployment tests to validate the deployments in each stage.

D : Use AWS CloudFormation to create and deploy the application infrastructure in each application environment. Use the AWS CLI to invoke Lambda functions to perform deployment tests after each deployment.

Answer: C

Question 3

A developer is setting up AWS CodePipeline for a new application. During each build, the developer mustgenerate a test report.Which solution will meet this requirement?

A : Create an AWS CodeBuild build project that runs tests. Configure the buildspec file with the test reportinformation.

B : Create an AWS CodeDeploy deployment that runs tests. Configure the AppSpec file with the test reportinformation.

C : Run the builds on an Amazon EC2 instance that has AWS Systems Manager Agent (SSM Agent)installed and activated.

D : Create a repository in AWS CodeArtifact. Select the test report template.

Answer: A

Question 4

A development team uses AWS CodeBuild as part of a CI/CD pipeline. The project includes hundreds of unitand integration tests, and total build time continues to increase. The team wants faster feedback and loweroverall testing duration without managing additional infrastructure.Which solution will meet these requirements with the LEAST operational overhead ?

A : Configure multiple CodeBuild projects and manually split tests across them.

B : Configure CodeBuild to split tests across multiple parallel compute environments.

C : Run all tests sequentially in a single CodeBuild environment.

D : Use Amazon EC2 instances with a custom test runner to distribute tests.

Answer: B

Question 5

A developer is building a serverless application by using AWS Serverless Application Model (AWS SAM) onmultiple AWS Lambda functions.When the application is deployed, the developer wants to shift 10% of the traffic to the new deployment ofthe application for the first 10 minutes after deployment. If there are no issues, all traffic must switch over tothe new version.Which change to the AWS SAM template will meet these requirements?

A : Set the Deployment Preference Type to Canary10Percent10Minutes. Set the AutoPublishAlias propertyto the Lambda alias.

B : Set the Deployment Preference Type to LinearlOPercentEvery10Minutes. Set AutoPubIishAIiasproperty to the Lambda alias.

C : Set the Deployment Preference Type to CanaryIOPercentIOMinutes. Set the PreTraffic and PostTrafficproperties to the Lambda alias.

D : Set the Deployment Preference Type to LinearlOPercentEveryIOMinutes. Set PreTraffic and PostTraffic properties to the Lambda alias.

Answer: A
