I used Cramkey Dumps to prepare and a lot of the questions on the exam were exactly what I found in their study materials.

Eric Jul 23, 2026

Really? That's great to hear! I used Cramkey Dumps too and I had the same experience. The questions were almost identical.

Osian

Dumps are fantastic! I recently passed my certification exam using these dumps and I must say, they are 100% valid.

Azaan Jul 11, 2026

They are incredibly accurate and valid. I felt confident going into my exam because the dumps covered all the important topics and the questions were very similar to what I saw on the actual exam. The team of experts behind Cramkey Dumps make sure the information is relevant and up-to-date.

Ilyas

Definitely. I felt much more confident and prepared because of the Cramkey Dumps. I was able to answer most of the questions with ease and I think that helped me to score well on the exam.

That's amazing. I'm glad you found something that worked for you. Maybe I should try them out for my next exam.

I want to ask about their study material and Customer support? Can anybody guide me?

Zayd Jul 24, 2026

Yes, the dumps or study material provided by them are authentic and up to date. They have a dedicated team to assist students and make sure they have a positive experience.

Question 37

A global company manages multiple AWS accounts by using AWS Control Tower. The company hosts internal applications and public applications.

Each application team in the company has its own AWS account for application hosting. The accounts are consolidated in an organization in AWS Organizations. One of the AWS Control Tower member accounts serves as a centralized DevOps account with CI/CD pipelines that application teams use to deploy applications to their respective target AWS accounts. An 1AM role for deployment exists in the centralized DevOps account.

An application team is attempting to deploy its application to an Amazon Elastic Kubernetes Service (Amazon EKS) cluster in an application AWS account. An 1AM role for deployment exists in the application AWS account. The deployment is through an AWS CodeBuild project that is set up in the centralized DevOps account. The CodeBuild project uses an 1AM service role for CodeBuild. The deployment is failing with an Unauthorized error during attempts to connect to the cross-account EKS cluster from CodeBuild.

Which solution will resolve this error?

Options:

Configure the application account ' s deployment 1AM role to have a trust relationship with the centralized DevOps account. Configure the trust relationship to allow the sts:AssumeRole action. Configure the application account ' s deployment 1AM role to have the required access to the EKS cluster. Configure the EKS cluster aws-auth ConfigMap to map the role to the appropriate system permissions.

Configure the centralized DevOps account ' s deployment I AM role to have a trust relationship with the application account. Configure the trust relationship to allow the sts:AssumeRole action. Configure the centralized DevOps account ' s deployment 1AM role to allow the required access to CodeBuild.

Configure the centralized DevOps account ' s deployment 1AM role to have a trust relationship with the application account. Configure the trust relationship to allow the sts:AssumeRoleWithSAML action. Configure the centralized DevOps account ' s deployment 1AM role to allow the required access to CodeBuild.

Configure the application account ' s deployment 1AM role to have a trust relationship with the AWS Control Tower management account. Configure the trust relationship to allow the sts:AssumeRole action. Configure the application account ' s deployment 1AM role to have the required access to the EKS cluster. Configure the EKS cluster aws-auth ConfigMap to map the role to the appropriate system permissions.

Question 38

A DevOps engineer uses AWS WAF to manage web ACLs across an AWS account. The DevOps engineer must ensure that AWS WAF is enabled for all Application Load Balancers (ALBs) in the account. The DevOps engineer uses an AWS CloudFormation template to deploy an individual ALB and AWS WAF as part of each application stack ' s deployment process. If AWS WAF is removed from the ALB after the ALB is deployed, AWS WAF must be added to the ALB automatically.

Which solution will meet these requirements with the MOST operational efficiency?

Options:

Enable AWS Config. Add the alb-waf-enabled managed rule. Create an AWS Systems Manager Automation document to add AWS WAF to an ALB. Edit the rule to automatically remediate. Select the Systems Manager Automation document as the remediation action.

Enable AWS Config. Add the alb-waf-enabled managed rule. Create an Amazon EventBridge rule to send all AWS Config ConfigurationItemChangeNotification notification types to an AWS Lambda function. Configure the Lambda function to call the AWS Config start-resource-evaluation API in detective mode.

Configure an Amazon EventBridge rule to periodically call an AWS Lambda function that calls the detect-stack-drift API on the CloudFormation template. Configure the Lambda function to modify the ALB attributes with waf.fail_open.enabled set to true if the AWS::WAFv2::WebACLAssociation resource shows a status of drifted.

Configure an Amazon EventBridge rule to periodically call an AWS Lambda function that calls the detect-stack-drift API on the CloudFormation template. Configure the Lambda function to delete and redeploy the CloudFormation stack if the AWS::WAFv2::WebACLAssociation resource shows a status of drifted.

Question 39

A company is running an application on Amazon EC2 instances in an Auto Scaling group. Recently an issue occurred that prevented EC2 instances from launching successfully and it took several hours for the support team to discover the issue. The support team wants to be notified by email whenever an EC2 instance does not start successfully.

Which action will accomplish this?

Options:

Add a health check to the Auto Scaling group to invoke an AWS Lambda function whenever an instance status is impaired.

Configure the Auto Scaling group to send a notification to an Amazon SNS topic whenever a failed instance launch occurs.

Create an Amazon CloudWatch alarm that invokes an AWS Lambda function when a failed Attachinstances Auto Scaling API call is made.

Create a status check alarm on Amazon EC2 to send a notification to an Amazon SNS topic whenever a status check fail occurs.
