AWS Certified DevOps Engineer - Professional Questions and Answers

Question 1

A company deploys an application to two AWS Regions. The application creates and stores objects in an Amazon S3 bucket that is in the same Region as the application. Both deployments of the application need to have access to all the objects and their metadata from both Regions. The company has configured two-way replication between the S3 buckets and has enabled S3 Replication metrics on each S3 bucket.

A DevOps engineer needs to implement a solution that retries the replication process if an object fails to replicate.

Which solution will meet these requirements?

Options:

A.

Create an Amazon EventBridge rule that listens to S3 event notifications for failed replication events. Create an AWS Lambda function that downloads the failed replication object and then runs a PutObject command for the object to the destination bucket. Configure the EventBridge rule to invoke the Lambda function to handle the object that failed to replicate.

B.

Create an Amazon Simple Queue Service (Amazon SQS) queue. Configure S3 event notifications to send failed replication notifications to the SQS queue. Create an AWS Lambda function that downloads the failed replication object and then runs a PutObject command for the object to the destination bucket. Configure the Lambda function to poll the queue for notifications to process.

C.

Create an Amazon EventBridge rule that listens to S3 event notifications for failed replications. Create an AWS Lambda function that downloads the failed replication object and then runs a PutObject command for the object to the destination bucket.

D.

Create an AWS Lambda function that will use S3 Batch Operations to retry the replication on the existing object for a failed replication. Configure S3 event notifications to send failed replication notifications to the Lambda function.

Question 2

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?

Options:

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.

Question 3

A company uses AWS CloudFormation stacks to deploy updates to its application. The stacks consist of different resources. The resources include AWS Auto Scaling groups, Amazon EC2 instances, Application Load Balancers (ALBs), and other resources that are necessary to launch and maintain independent stacks. Changes to application resources outside of CloudFormation stack updates are not allowed.

The company recently attempted to update the application stack by using the AWS CLI. The stack failed to update and produced the following error message: " ERROR: both the deployment and the CloudFormation stack rollback failed. The deployment failed because the following resource(s) failed to update: [AutoScalingGroup]. "

The stack remains in a status of UPDATE_ROLLBACK_FAILED. *

Which solution will resolve this issue?

Options:

A.

Update the subnet mappings that are configured for the ALBs. Run the aws cloudformation update-stack-set AWS CLI command.

B.

Update the 1AM role by providing the necessary permissions to update the stack. Run the aws cloudformation continue-update-rollback AWS CLI command.

C.

Submit a request for a quota increase for the number of EC2 instances for the account. Run the aws cloudformation cancel-update-stack AWS CLI command.

D.

Delete the Auto Scaling group resource. Run the aws cloudformation rollback-stack AWS CLI command.
