Free Amazon DOP-C02 Exam Questions

Question 1

A DevOps engineer is supporting early-stage development for a developer platform running on Amazon EKS. Recently, the platform has experienced an increased rate of container restart failures. The DevOps engineer wants diagnostic information to isolate and resolve issues. Which solution will meet this requirement?

A : Configure CloudWatch dashboards using default EKS service metrics.

B : Configure AWS CloudTrail for the EKS cluster.

C : Configure CloudTrail Insights for the EKS cluster.

D : Configure Amazon CloudWatch Container Insights for the EKS cluster by enabling the CloudWatch Observability add-on.

Answer: D

Question 2

A DevOps engineer manages a web application that runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances run in an EC2 Auto Scaling group across multiple Availability Zones. The engineer needs to implement a deployment strategy that:

Launches a second fleet of instances with the same capacity as the original fleet.

Maintains the original fleet unchanged while the second fleet is launched.

Transitions traffic to the second fleet when the second fleet is fully deployed.

Terminates the original fleet automatically 1 hour after transition.

Which solution will satisfy these requirements?

A : an AWS CloudFormation template with a retention policy for the ALB set to 1 hour. Update the Amazon Route 53 record to reflect the new ALB

B : two AWS Elastic Beanstalk environments to perform a blue/green deployment from the original environment to the new one. Create an application version lifecycle policy to terminate the original environment in 1 hour.

C : AWS CodeDeploy with a deployment group configured with a blue/green deployment configuration Select the option Terminate the original instances in the deployment group with a waiting period of 1 hour.

D : AWS Elastic Beanstalk with the configuration set to Immutable. Create an .ebextension using the Resources key that sets the deletion policy of the ALB to 1 hour, and deploy the application.

Answer: C

Question 3

A company runs an Amazon EKS cluster and must implement comprehensive logging for the control plane and nodes. The company must analyze API requests and monitor container performance. Which solution will meet these requirements with the LEAST operational overhead?

A : Enable AWS CloudTrail for control plane logging and deploy Logstash on nodes.

B : Enable control plane logging to CloudWatch and use CloudWatch Container Insights for node and pod metrics.

C : Enable API server logging to S3 and deploy Kubernetes Event Exporter to nodes.

D : Use AWS Distro for OpenTelemetry and stream logs to Amazon Redshift.

Answer: B

Question 4

A development team manually builds a local artifact. The development team moves the artifact to an Amazon S3 bucket to support an application. The application has a local cache that must be cleared when the development team deploys the application to Amazon EC2 instances. For each deployment, the development team runs a command to clear the cache, download the artifact from the S3 bucket, and unzip the artifact to complete the deployment. The development team wants to migrate the deployment process to a CI/CD process and to track the progress of each deployment. Which combination of actions will meet these requirements with the MOST operational efficiency? (Select THREE.)

A : Set up an AWS CodeConnections compatible Git repository. Allow developers to merge code into the repository. Use AWS CodeBuild to build an artifact and copy the object into the S3 bucket. Configure CodeBuild to run for every merge into the main branch.

B : Create a custom script to clear the cache. Specify the script in the BeforeInstall lifecycle hook in the AppSpec file.

C : Create user data for each EC2 instance that contains the cache clearing script. Test the application after deployment. If the deployment is not successful, then redeploy.

D : Use AWS CodePipeline to deploy the application. Set up an AWS CodeConnections compatible Git repository. Allow developers to merge code into the repository as a source for the pipeline.

E : Use AWS CodeBuild to build the artifact and place the artifact in the S3 bucket. Use AWS CodeDeploy to deploy the artifact to EC2 instances.

F : Use AWS Systems Manager to fetch the artifact from the S3 bucket and to deploy the artifact to all the EC2 instances.

Answer: B,D,E

Question 5

A company must encrypt all AMIs that the company shares across accounts. A DevOps engineer has access to a source account where an unencrypted custom AMI has been built. The DevOps engineer also has access to a target account where an Amazon EC2 Auto Scaling group will launch EC2 instances from the AMI. The DevOps engineer must share the AMI with the target account.

The company has created an AWS Key Management Service (AWS KMS) key in the source account.

Which additional steps should the DevOps engineer perform to meet the requirements? (Choose three.)

A : the source account, copy the unencrypted AMI to an encrypted AMI. Specify the KMS key in the copy action.

B : the source account, copy the unencrypted AMI to an encrypted AMI. Specify the default Amazon Elastic Block Store (Amazon EBS) encryption key in the copy action.

C : the source account, create a KMS grant that delegates permissions to the Auto Scaling group service-linked role in the target account.

D : the source account, modify the key policy to give the target account permissions to create a grant. In the target account, create a KMS grant that delegates permissions to the Auto Scaling group service-linked role

E : the source account, share the unencrypted AMI with the target account.

F : the source account, share the encrypted AMI with the target account.

Answer: A,D
