Free Amazon DOP-C02 Exam Questions

Question 1

A software development company is using AWS CodeCommit, AWS CodeBuild, AWS CodeDeploy, and AWS CodePipeline for its CI/CD process. To further improve their systems, they need to implement a solution that automatically detects and reacts to changes in the state of their deployments in AWS CodeDeploy. Any changes must be rolled back automatically if the deployment process fails, and a notification must be sent to the DevOps Team's Slack channel for easy monitoring.

Which of the following is the MOST suitable configuration that you should implement to satisfy this requirement?

A : t up a CloudWatch Events rule to monitor AWS CodeDeploy operations with a Lambda function as a target. Configure the rule to send out a message to the DevOps Team's Slack Channel in the event that the deployment fails. Configure AWS CodeDeploy to use the Roll back when a deployment fails setting.

B : nitor the API calls in the CodeDeploy project using AWS CloudTrail. Send a message to the DevOps Team's Slack Channel when the PutLifecycleEventHookExecutionStatus API call has been detected. Rollback the changes by using the AWS CLI.

C : t up a CloudWatch Alarm that tracks the CloudWatch metrics of the CodeDeploy project. Configure the CloudWatch Alarm to automatically send out a message to the DevOps Team's Slack Channel when the deployment fails. Configure AWS CodeDeploy to use the Roll back when alarm thresholds are met setting.

D : nfigure a CodeDeploy agent to send notification to the DevOps Team's Slack Channel when the deployment fails. Configure AWS CodeDeploy to automatically roll back whenever the deployment is not successful.

Answer: A

Question 2

A company has a suite of applications that are hosted in AWS and each app has its own AMI. Currently, a new AMI must be manually created and deployed to the server if there is a new application version. A DevOps engineer was instructed to automate the process of generating the AMIs to streamline the company's CI/CD workflow. The ID of the newly created AMI must be stored in a centralized location where other build pipelines can programmatically access it.

Which of the following is the MOST cost-effective way to accomplish this requirement with the LEAST amount of overhead?

A : t up a brand new pipeline in AWS CodePipeline with several EC2 instances for processing. Configure it to download and save the latest operating system of the application in an Open Virtualization Format (OVF) image format and then store the image in an S3 bucket. Customize the image using guestfish interactive shell or the virt-rescue shell. Convert the OVF to an AMI using the virtual machine (VM) import command and then store the AMI IDs in AWS Systems Manager Parameter Store.

B : ing AWS Systems Manager, create an Automation document with values that configure how the machine image should be created. Launch a new pipeline with a custom action in AWS CodePipeline and integrate it with Amazon Eventbridge to execute the automation document. Build the AMI when the process is triggered. Store the AMI IDs in Systems Manager Parameter Store.

C : an open-source machine image creation tool such as Packer then configure it with values defining how the AMI should be created. Set up a Jenkins pipeline hosted in a large EC2 instance to start the Packer when triggered to build an AMI. Store the AMI IDs to an Amazon DynamoDB table.

D : ing AWS CodePipeline, set up a new pipeline that will take an EBS snapshot of the EBS-backed EC2 instance which runs the latest version of each application. Launch a new EC2 instance from the generated snapshot and update the running instance using a Lambda function. Take a snapshot of the updated EC2 instance and then afterward, convert it to an Amazon Machine Image (AMI). Store all of the AMI IDs in an S3 bucket.

Answer: B

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 software team is using AWS CodePipeline to automate its Java application release pipeline. The pipeline consists of a source stage, then a build stage, and then a deploy stage. Each stage contains a single action that has a runOrder value of 1.

The team wants to integrate unit tests into the existing release pipeline. The team needs a solution that deploys only the code changes that pass all unit tests.

Which solution will meet these requirements?

A : Modify the build stage. Add a test action that has a runOrder value of 1. Use AWS CodeDeploy as the action provider to run unit tests.

B : Modify the build stage. Add a test action that has a runOrder value of 2. Use AWS CodeBuild as the action provider to run unit tests.

C : Modify the deploy stage. Add a test action that has a runOrder value of 1. Use AWS CodeDeploy as the action provider to run unit tests.

D : Modify the deploy stage. Add a test action that has a runOrder value of 2. Use AWS CodeBuild as the action provider to run unit tests.

Answer: C

Question 5

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
