AWS Certified DevOps Engineer - Professional Questions and Answers

Question 1

A company is using AWS CodePipeline to automate its release pipeline. AWS CodeDeploy is being used in the pipeline to deploy an application to Amazon Elastic Container Service (Amazon ECS) using the blue/green deployment model. The company wants to implement scripts to test the green version of the application before shifting traffic. These scripts will complete in 5 minutes or less. If errors are discovered during these tests, the application must be rolled back.

Which strategy will meet these requirements?

Options:

A.

Add a stage to the CodePipeline pipeline between the source and deploy stages. Use AWS CodeBuild to create a runtime environment and build commands in the buildspec file to invoke test scripts. If errors are found, use the aws deploy stop-deployment command to stop the deployment.

B.

Add a stage to the CodePipeline pipeline between the source and deploy stages. Use this stage to invoke an AWS Lambda function that will run the test scripts. If errors are found, use the aws deploy stop-deployment command to stop the deployment.

C.

Add a hooks section to the CodeDeploy AppSpec file. Use the AfterAllowTestTraffic lifecycle event to invoke an AWS Lambda function to run the test scripts. If errors are found, exit the Lambda function with an error to initiate rollback.

D.

Add a hooks section to the CodeDeploy AppSpec file. Use the AfterAllowTraffic lifecycle event to invoke the test scripts. If errors are found, use the aws deploy stop-deployment CLI command to stop the deployment.

Question 2

A company uses an organization in AWS Organizations that has all features enabled to manage multiple AWS accounts. The company has enabled AWS Config in all accounts. The company requires developers to create AWS CloudFormation stacks in a new AWS account to test features for a new application that the developers are building.

The company wants to ensure that the developers can use only approved Amazon EC2 instance types for the application.

Which solution will meet these requirements?

Options:

A.

Create an AWS Lambda function that returns SUCCESS when the EC2 instance type property matches a value from a list of approved instance types. Activate a CloudFormation Guard Hook in the new AWS account to run the Lambda function.

B.

Create an AWS Config rule that uses the desired-instance-type rule in the new AWS account. Provide the list of approved instance types in the rule configuration. Create a remediation for the AWS Config rule that uses the AWS-StopEC2Instance remediation action.

C.

Create an SCP that includes a Deny effect for ec2:RunInstances when the ec2:InstanceType property does not match a value from a list of approved instance types. Attach the SCP to the root of the organization.

D.

Create a CloudFormation Guard rule to ensure that the EC2 instance type matches a value from a list of approved instance types. Activate a Guard Hook in the new AWS account to run the Guard rule.

Question 3

A company hosts a security auditing application in an AWS account. The auditing application uses an IAM role to access other AWS accounts. All the accounts are in the same organization in AWS Organizations.

A recent security audit revealed that users in the audited AWS accounts could modify or delete the auditing application ' s IAM role. The company needs to prevent any modification to the auditing application ' s IAM role by any entity other than a trusted administrator IAM role.

Which solution will meet these requirements?

Options:

A.

Create an SCP that includes a Deny statement for changes to the auditing application ' s IAM role. Include a condition that allows the trusted administrator IAM role to make changes. Attach the SCP to the root of the organization.

B.

Create an SCP that includes an Allow statement for changes to the auditing application ' s IAM role by the trusted administrator IAM role. Include a Deny statement for changes by all other IAM principals. Attach the SCP to the IAM service in each AWS account where the auditing application has an IAM role.

C.

Create an IAM permissions boundary that includes a Deny statement for changes to the auditing application ' s IAM role. Include a condition that allows the trusted administrator IAM role to make changes. Attach the permissions boundary to the audited AWS accounts.

D.

Create an IAM permissions boundary that includes a Deny statement for changes to the auditing application’s IAM role. Include a condition that allows the trusted administrator IAM role to make changes. Attach the permissions boundary to the auditing application ' s IAM role in the AWS accounts.
