AWS Certified DevOps Engineer - Professional Questions and Answers

Question 1

A company uses an organization in AWS Organizations with all features enabled to manage a fleet of AWS accounts. The company expects to create many new accounts for an upcoming project.

The company wants to ensure that the new accounts will not have default VPCs and that users can develop only in specific AWS Regions. The company must monitor the new accounts for compliance with the Center for Internet Security (CIS) AWS Foundations Benchmark framework.

Which combination of solutions will meet these requirements with the LEAST operational effort? (Select TWO.)

Options:

A.

Activate AWS Control Tower. Configure AWS Control Tower to disable internet-accessible subnets. Set the maximum number of private subnets to zero. Configure Region denies, and ensure that users can access only the specified Regions.

B.

Activate AWS Control Tower. Install Customizations for AWS Control Tower (CfCT). Develop a custom AWS CloudFormation template to delete default VPCs. Configure Region denies, and ensure that users can access only the specified Regions.

C.

Write an SCP that denies access to all Regions except the specified Regions. Create an AWS Lambda function that assumes an IAM role by using the Organizations default service role in each member account to identify and delete default VPCs. Create an Amazon EventBridge rule that invokes the Lambda function when the company creates a new AWS account.

D.

Activate AWS Security Hub at the organization level. Select the CIS AWS Foundations Benchmark framework, and apply the framework to the organization.

E.

B.

Enhanced scanning, Lambda invokes Inspector for SBOM, exports to S3, Athena queries SBOM, rejects manual approval on critical findings.

C.

Enhanced scanning, EventBridge listens to Detective scan findings, Lambda rejects manual approval on critical vulnerabilities.

D.

Question 3

A DevOps engineer has implemented a Cl/CO pipeline to deploy an AWS Cloud Format ion template that provisions a web application. The web application consists of an Application Load Balancer (ALB) a target group, a launch template that uses an Amazon Linux 2 AMI an Auto Scaling group of Amazon EC2 instances, a security group and an Amazon RDS for MySQL database The launch template includes user data that specifies a script to install and start the application.

The initial deployment of the application was successful. The DevOps engineer made changes to update the version of the application with the user data. The CI/CD pipeline has deployed a new version of the template However, the health checks on the ALB are now failing The health checks have marked all targets as unhealthy.

During investigation the DevOps engineer notices that the Cloud Formation stack has a status of UPDATE_COMPLETE. However, when the DevOps engineer connects to one of the EC2 instances and checks /varar/log messages, the DevOps engineer notices that the Apache web server failed to start successfully because of a configuration error

How can the DevOps engineer ensure that the CloudFormation deployment will fail if the user data fails to successfully finish running?

Options:

A.

Use the cfn-signal helper script to signal success or failure to CloudFormation Use the WaitOnResourceSignals update policy within the CloudFormation template Set an appropriate timeout for the update policy.

B.

Create an Amazon CloudWatch alarm for the UnhealthyHostCount metric. Include an appropriate alarm threshold for the target group Create an Amazon Simple Notification Service (Amazon SNS) topic as the target to signal success or failure to CloudFormation

C.

Create a lifecycle hook on the Auto Scaling group by using the AWS AutoScaling LifecycleHook resource Create an Amazon Simple Notification Service (Amazon SNS) topic as the target to signal success or failure to CloudFormation Set an appropriate timeout on the lifecycle hook.

D.

Use the Amazon CloudWatch agent to stream the cloud-init logs Create a subscription filter that includes an AWS Lambda function with an appropriate invocation timeout Configure the Lambda function to use the SignalResource API operation to signal success or failure to CloudFormation.
