Free Amazon DOP-C02 Exam Questions

Question 1

An American tech company used an AWS CloudFormation template to deploy its static corporate website hosted on Amazon S3 in the US East (N. Virginia) region. The template defines an Amazon S3 bucket with a Lambda-backed custom resource that downloads the content from a file server into the bucket. There is a new task for the DevOps Engineer to move the website to the US West (Oregon) region to better serve its customers on the West Coast with lower latency. However, the application stack could not be deleted successfully in CloudFormation.

Which among the following options shows the root cause of this issue, and how can the DevOps Engineer mitigate this problem for current and future versions of the website?

A : CloudFormation stack deletion fails for an S3 bucket that is used as a static web hosting. To fix the issue, modify the CloudFormation template to remove the website configuration for the S3 bucket.

B : CloudFormation stack deletion fails for an S3 bucket because the DeletionPolicy attribute is set to Snapshot. To fix the issue, set the DeletionPolicy to Delete instead.

C : CloudFormation stack deletion fails for an S3 bucket that still has contents. To fix the issue, modify the Lambda function code of the custom resource to recursively empty the bucket if the stack is selected for deletion.

D : CloudFormation stack deletion fails for an S3 bucket because it is not yet empty. To fix the issue, set the DeletionPolicy to ForceDelete instead.

Answer: C

Question 2

A DevOps engineer needs a resilient CI/CD pipeline that builds container images, stores them in ECR, scans images for vulnerabilities, and is resilient to outages in upstream source image repositories. Which solution meets this?

A : Create a private ECR repo, scan images on push, replicate images from upstream repos with a replication rule.

B : Create a private ECR repo, scan images on push, replicate images from upstream repos with a replication rule

C : Create a public ECR repo, configure a pull-through cache rule, create a private repo to store images, enable basic scanning.

D : Create a private ECR repo, enable basic scanning, create a pull-through cache rule.

Answer: D

Question 3

A company uses AWS Control Tower and Organizations for a multi-account environment. It needs to create new accounts and ensure they receive a consistent baseline configuration. Which solution meets the requirement with the least overhead?

A : Use Account Factory Customization (AFC) blueprints for baseline setup.

B : Use Account Factory + StackSets post-setup.

C : Use Organizations with Lambda applying baseline via access role.

D : Use Organizations + StackSets manually.

Answer: A

Question 4

A DevOps engineer needs to configure an AWS CodePipeline pipeline that publishes container images to an Amazon ECR repository. The pipeline must wait for the previous run to finish and must run when new Git tags are pushed to a Git repository connected to AWS CodeConnections. An existing deployment pipeline must run in response to new container image publications. Which solution will meet these requirements?

A : Configure a CodePipeline V2 type pipeline that uses QUEUED mode. Add a trigger filter to the pipeline definition that includes all tags. Configure an EventBridge rule that matches container image pushes to start the existing deployment pipeline.

B : Configure a CodePipeline V2 type pipeline that uses SUPERSEDED mode. Add a trigger filter to the pipeline definition that includes all branches. Configure an EventBridge rule that matches container image pushes to start the existing deployment pipeline.

C : Configure a CodePipeline V1 type pipeline that uses SUPERSEDED mode. Add a trigger filter to the pipeline definition that includes all tags. Add a stage at the end of the pipeline to invoke the existing deployment pipeline.

D : Configure a CodePipeline V1 type pipeline that uses QUEUED mode. Add a trigger filter to the pipeline definition that includes all branches. Add a stage at the end of the pipeline to invoke the existing deployment pipeline.

Answer: A

Question 5

A company has several AWS accounts. An Amazon Connect instance runs in each account. The company uses an Amazon EventBridge default event bus in each account for event handling. A DevOps team needs to receive all the Amazon Connect events in a single DevOps account. Which solution meets these requirements?

A : Update the resource-based policy of the default event bus in each account to allow the DevOps account to replay events. Configure an EventBridge rule in the DevOps account that matches Amazon Connect events and has a target of the default event bus in the other accounts.

B : Update the resource-based policy of the default event bus in each account to allow the DevOps account to receive events. Configure an EventBridge rule in the DevOps account that matches Amazon Connect events and has a target of the default event bus in the other accounts.

C : Update the resource-based policy of the default event bus in the DevOps account. Update the policy to allow events to be received from the accounts. Configure an EventBridge rule in each account that matches Amazon Connect events and has a target of the DevOps account's default event bus

D : Update the resource-based policy of the default event bus in the DevOps account. Update the policy to allow events to be replayed by the accounts. Configure an EventBridge rule in each account that matches Amazon Connect events and has a target of the DevOps account's default event bus.

Answer: C
