AWS Certified DevOps Engineer - Professional Questions and Answers

Question 77

A DevOps engineer successfully creates an Amazon Elastic Kubernetes Service (Amazon EKS) cluster that includes managed node groups. When the DevOps engineer tries to add node groups to the cluster, the cluster returns an error that states, "NodeCreationFailure: Instances failed to join the Kubernetes cluster." The DevOps engineer confirms that the EC2 worker nodes are running and that the EKS cluster is in an active state. How should the DevOps engineer troubleshoot this issue?

Options:

A.

Ensure that the EKS cluster's VPC subnets do not overlap with the 172.17.0.0/16 CIDR range.

B.

Use kubectl to update the kubeconfig file to use the credentials that created the cluster.

C.

Run the AWSSupport-TroubleshootEKSWorkerNode runbook.

D.

Create an AWS Identity and Access Management (IAM) OpenID Connect (OIDC) provider for the cluster.

Question 78

A DevOps engineer has developed an AWS Lambda function The Lambda function starts an AWS CloudFormation drift detection operation on all supported resources for a specific CloudFormation stack The Lambda function then exits Its invocation The DevOps engineer has created an Amazon EventBrdge scheduled rule that Invokes the Lambda function every hour. An Amazon Simple Notification Service (Amazon SNS) topic already exists In the AWS account. The DevOps engineer has subscribed to the SNS topic to receive notifications

The DevOps engineer needs to receive a notification as soon as possible when drift is detected in this specific stack configuration.

Which solution Will meet these requirements?

Options:

A.

Configure the existing EventBridge rule to also target the SNS topic Configure an SNS subscription filter policy to match the Cloud Formation stack. Attach the subscription filter policy to the SNS tomc

B.

Create a second Lambda function to query the CloudFormation API for the drift detection results for the stack Configure the second Lambda function to publish a message to the SNS topic If drift ts detected Adjust the existing EventBridge rule to also target the second Lambda function

C.

Configure Amazon GuardDuty in the account with drift detection for all CloudFormation stacks. Create a second EventBndge rule that reacts to the GuardDuty drift detection event finding for the specific CloudFormation stack. Configure the SNS topic as a target of the second EventBridge rule.

D.

Configure AWS Config in the account. Use the cloudformation-stack-drift-detection-check managed rule. Create a second EventBndge rule that reacts to a compliance change event for the CloudFormaUon stack. Configure the SNS topc as a target of the second EventBridge rule.

Question 79

A company has an on-premises application that is written in Go. A DevOps engineer must move the application to AWS. The company's development team wants to enable blue/green deployments and perform A/B testing.

Which solution will meet these requirements?

Options:

A.

Deploy the application on an Amazon EC2 instance, and create an AMI of the instance. Use the AMI to create an automatic scaling launch configuration that is used in an Auto Scaling group. Use Elastic Load Balancing to distribute traffic. When changes are made to the application, a new AMI will be created, which will initiate an EC2 instance refresh.

B.

Use Amazon Lightsail to deploy the application. Store the application in a zipped format in an Amazon S3 bucket. Use this zipped version to deploy new versions of the application to Lightsail. Use Lightsail deployment options to manage the deployment.

C.

Use AWS CodeArtifact to store the application code. Use AWS CodeDeploy to deploy the application to a fleet of Amazon EC2 instances. Use Elastic Load Balancing to distribute the traffic to the EC2 instances. When making changes to the application, upload a new version to CodeArtifact and create a new CodeDeploy deployment.

D.

Use AWS Elastic Beanstalk to host the application. Store a zipped version of the application in Amazon S3. Use that location to deploy new versions of the application. Use Elastic Beanstalk to manage the deployment options.

Question 80

A company runs an application in an Auto Scaling group of Amazon EC2 instances behind an Application Load Balancer (ALB). The EC2 instances run Docker containers that make requests to a MySQL database that runs on separate EC2 instances. A DevOps engineer needs to update the application to use a serverless architecture. Which solution will meet this requirement with the FEWEST changes?

Options:

A.

Replace the containers that run on EC2 instances and the ALB with AWS Lambda functions. Replace the MySQL database with an Amazon Aurora Serverless v2 database that is compatible with MySQL.

B.

Replace the containers that run on EC2 instances with AWS Fargate. Replace the MySQL database with an Amazon Aurora Serverless v2 database that is compatible with MySQL.

C.

Replace the containers that run on EC2 instances and the ALB with AWS Lambda functions. Replace the MySQL database with Amazon DynamoDB tables.

D.

Replace the containers that run on EC2 instances with AWS Fargate. Replace the MySQL database with Amazon DynamoDB tables.
