Free Amazon DOP-C02 Exam Questions

Question 1

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

Question 2

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 3

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 4

A leading media company has recently moved its .NET web application from its on-premises network to AWS Elastic Beanstalk for easier deployment and management. An Amazon S3 bucket stores static contents such as PDF files, images, videos, and the likes. An Amazon DynamoDB table stores all of the data of the application. The company has recently launched a series of global marketing campaigns that resulted in unpredictable spikes of incoming traffic. Upon checking, the Operations team discovered that over 80% of the traffic is just duplicate read requests.

As a DevOps Engineer, how can you improve the application's performance for its users around the world?

A : Lambda@Edge to cache the images stored in the S3 bucket. Use DynamoDB Accelerator (DAX) to cache repeated read requests on the web application.

B : che the images stored in the S3 bucket using the AWS Elemental MediaPackage. Set up a distributed cache layer using an ElastiCache for Memcached Cluster to serve the repeated read requests on the web application.

C : eate a CloudFront web distribution to cache images stored in the S3 bucket. Use DynamoDB Accelerator (DAX) to cache repeated read requests on the web application.

D : che the images stored in the S3 bucket using the AWS Elemental MediaStore. Set up a distributed cache layer using an ElastiCache for Redis Cluster to serve the repeated read requests on the web application.

Answer: C

Question 5

A leading software development company has various web applications hosted in an Auto Scaling group of EC2 instances which are designed for high availability and fault tolerance. They are using AWS CloudFormation to easily manage their cloud infrastructure as code as well as for deployment. Currently, they have to manually update their CloudFormation templates for every new available AMI of their application. This procedure is prone to human errors and entails a high management overhead on their deployment process.

Which of the following is the MOST suitable and cost-effective solution that the DevOps engineer should implement to automate this process?

A : ll the new AMI IDs using an AWS Lambda-backed custom resource in the CloudFormation template. Reference the AMI ID that the custom resource fetched in the launch configuration resource block.

B : nfigure the CloudFormation template to use AMI mappings. Integrate AWS Lambda and Amazon CloudWatch Events to create a function that regularly runs every hour to detect new AMIs as well as update the mapping in the template. Reference the AMI mappings in the launch configuration resource block.

C : nfigure the AWS CloudFormation template to use conditional statements to check if new AMIs are available. Fetch the new AMI ID using the cfn-init helper script and reference it in the launch configuration resource block.

D : unch an EC2 instance to run a custom shell script every hour to check for new AMIs. The script should update the launch configuration resource block of the CloudFormation template with the new AMI ID if there are new ones available.

Answer: A
