DOP-C02 Exam Question 106

A company uses the AWS Cloud Development Kit (AWS CDK) to define its application. The company uses a pipeline that consists of AWS CodePipeline and AWS CodeBuild to deploy the CDK application. The company wants to introduce unit tests to the pipeline to test various infrastructure components. The company wants to ensure that a deployment proceeds if no unit tests result in a failure.
Which combination of steps will enforce the testing requirement in the pipeline? (Select TWO.)

A.Update the CodeBuild build phase commands to run the tests then to deploy the application. Set the OnFailure phase property to ABORT.

B.Update the CodeBuild build phase commands to run the tests then to deploy the application. Add the -- rollback true flag to the cdk deploy command.

C.Update the CodeBuild build phase commands to run the tests then to deploy the application. Add the -- require-approval any-change flag to the cdk deploy command.

D.Create a test that uses the AWS CDK assertions module. Use the template.hasResourceProperties assertion to test that resources have the expected properties.

E.Create a test that uses the cdk diff command. Configure the test to fail if any resources have changed.

DOP-C02 Exam Question 107

A company is building a new pipeline by using AWS CodePipeline and AWS CodeBuild in a build account.
The pipeline consists of two stages. The first stage is a CodeBuild job to build and package an AWS Lambda function. The second stage consists of deployment actions that operate on two different AWS accounts a development environment account and a production environment account. The deployment stages use the AWS Cloud Format ion action that CodePipeline invokes to deploy the infrastructure that the Lambda function requires.
A DevOps engineer creates the CodePipeline pipeline and configures the pipeline to encrypt build artifacts by using the AWS Key Management Service (AWS KMS) AWS managed key for Amazon S3 (the aws/s3 key).
The artifacts are stored in an S3 bucket When the pipeline runs, the Cloud Formation actions fail with an access denied error.
Which combination of actions must the DevOps engineer perform to resolve this error? (Select TWO.)

A.Create an AWS managed KMS key Configure the KMS key policy to allow the development account and the production account to perform decrypt operations. Modify the pipeline to use the KMS key to encrypt artifacts.

B.Create an S3 bucket in each AWS account for the artifacts Allow the pipeline to write to the S3 buckets.
Create a CodePipeline S3 action to copy the artifacts to the S3 bucket in each AWS account Update the CloudFormation actions to reference the artifacts S3 bucket in the production account.

C.In the development account and in the production account create an IAM role for CodePipeline Configure the roles with permissions to perform CloudFormation operations and with permissions to retrieve and decrypt objects from the artifacts S3 bucket. In the CodePipelme account modify the artifacts S3 bucket policy to allow the roles access Configure the CodePipeline CloudFormation action to use the roles.

D.Create a customer managed KMS key Configure the KMS key policy to allow the IAM roles used by the CloudFormation action to perform decrypt operations Modify the pipeline to use the customer managed KMS key to encrypt artifacts.

E.In the development account and in the production account create an IAM role for CodePipeline.
Configure the roles with permissions to perform CloudFormation operations and with permissions to retrieve and decrypt objects from the artifacts S3 bucket. In the CodePipeline account configure the CodePipeline CloudFormation action to use the roles.

DOP-C02 Exam Question 108

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?

A.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.

B.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.

C.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.

D.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.

DOP-C02 Exam Question 109

A software engineering team is using AWS CodeDeploy to deploy a new version of an application. The team wants to ensure that if any issues arise during the deployment, the process can automatically roll back to the previous version.
During the deployment process, a health check confirms the application's stability. If the health check fails, the deployment must revert automatically.
Which solution will meet these requirements?

A.Implement lifecycle event hooks in the deployment configuration.

B.Use AWS CloudFormation to monitor the health of the deployment.

C.Set up alarms in Amazon CloudWatch to start a rollback.

D.Configure automatic rollback settings in AWS CodeDeploy.

DOP-C02 Exam Question 110

A DevOps team operates an integration service that runs on an Amazon EC2 instance. The DevOps team uses Amazon Route 53 to manage the integration service's domain name by using a simple routing record. The integration service is stateful and uses Amazon Elastic File System (Amazon EFS) for data storage and state storage. The integration service does not support load balancing between multiple nodes. The DevOps team deploys the integration service on a new EC2 instance as a warm standby to reduce the mean time to recovery.
The DevOps team wants the integration service to automatically fail over to the standby EC2 instance. Which solution will meet these requirements?

A.Create an Application Load Balancer (ALB). Update the existing Route 53 record to point to the ALB.
Create a target group for each EC2 instance. Configure an application health check on each target group. Associate both target groups with the same ALB listener. Set the primary target group's weighting to 100. Set the standby target group's weighting to 0.

B.Create an Application Load Balancer (ALB). Update the existing Route 53 record to point to the ALB.Create a target group for each EC2 instance. Configure an application health check on each target group. Associate both target groups with the same ALB listener. Set the primary target group's weighting to 99. Set the standby target group's weighting to 1.

C.Update the existing Route 53 DNS record's routing policy to weighted. Set the existing DNS record's weighting to 99. For the same domain, add a new DNS record that points to the standby EC2 instance.
Set the new DNS record's weighting to 1. Associate an application health check with each record.

D.Update the existing Route 53 DNS record's routing policy to weighted. Set the existing DNS record's weighting to 100. For the same domain, add a new DNS record that points to the standby EC2 instance.
Set the new DNS record's weighting to 0. Associate an application health check with each record.
