Question 1

A DevOps engineer must implement a solution that immediately terminates Amazon EC2 instances in Auto Scaling groups when cryptocurrency mining activity is detected. Which solution will meet these requirements with the LEAST development effort?

A : Configure Amazon Route 53 query logs # CloudWatch # Lambda every 5 mins to detect mining-related domains and terminate EC2 instances.

B : Configure VPC Flow Logs # S3 # Lambda every 5 mins # Athena query # terminate EC2 instances.

C : Enable Amazon GuardDuty. Monitor EC2 findings. Create an EventBridge rule triggered by GuardDuty. Invoke a Lambda function that terminates the affected EC2 instances.

D : Enable AWS Security Hub. Monitor EC2 findings. Create an EventBridge rule triggered by SecurityHub. Invoke Lambda to terminate EC2 instances.

Answer: C

Question 3

A DevOps engineer is implementing governance controls for a company that requires its infrastructure to be

housed within the United States. The engineer must restrict which AWS Regions can be used, and ensure an

alert is sent as soon as possible if any activity outside the governance policy takes place. The controls should

be automatically enabled on any new Region outside the United States (US).

Which combination of actions will meet these requirements? (Select TWO.)

A : Create an AWS Organizations SCP that denies access to all non-global services in non-US Regions. Attach the policy to the root of the organization.

B : Configure AWS CloudTrail to send logs to Amazon CloudWatch Logs and enable it for all Regions. Use a CloudWatch Logs metric filter to send an alert on any service activity in non-US Regions.

C : Use an AWS Lambda function that checks for AWS service activity and deploy it to all Regions. Write an Amazon EventBridge rule that runs the Lambda function every hour, sending an alert if activity is found in a non-US Region.

D : Use an AWS Lambda function to query Amazon Inspector to look for service activity in non-US Regions and send alerts if any activity is found.

E : Write an SCP using the aws: RequestedRegion condition key limiting access to US Regions. Apply the policy to all users, groups, and roles

Answer: A,B

Question 4

A DevOps engineer needs a resilient CI/CD pipeline that builds container images, stores them in ECR, scans images for vulnerabilities, and is resilient to outages in upstream source image repositories. Which solution meets this?

A : Create a private ECR repo, scan images on push, replicate images from upstream repos with a replication rule.

B : Create a private ECR repo, scan images on push, replicate images from upstream repos with a replication rule

C : Create a public ECR repo, configure a pull-through cache rule, create a private repo to store images, enable basic scanning.

D : Create a private ECR repo, enable basic scanning, create a pull-through cache rule.

Answer: D

Question 5

A company is building a new pipeline by using AWS CodePipeline and AWS CodeBuild in a build account. The pipeline consists of two stages. The first stage is a CodeBuild job to build and package an AWS Lambda function. The second stage consists of deployment actions that operate on two different AWS accounts: a development environment account and a production environment account. The deployment stages use the AWS CloudFormation action that CodePipeline invokes to deploy the infrastructure that the Lambda function requires.

A DevOps engineer creates the CodePipeline pipeline and configures the pipeline to encrypt build artifacts by using the AWS Key Management Service (AWS KMS) AWS managed key for Amazon S3 (the aws/s3 key). The artifacts are stored in an S3 bucket. When the pipeline runs, the CloudFormation actions fail with an access denied error.

Which combination of actions must the DevOps engineer perform to resolve this error? (Choose two.)

A : eate an S3 bucket in each AWS account for the artifacts. Allow the pipeline to write to the S3 buckets. Create a CodePipeline S3 action to copy the artifacts to the S3 bucket in each AWS account. Update the CloudFormation actions to reference the artifacts S3 bucket in the production account.

B : eate a customer managed KMS key. Configure the KMS key policy to allow the IAM roles used by the CloudFormation action to perform decrypt operations. Modify the pipeline to use the customer managed KMS key to encrypt artifacts.

C : eate an AWS managed KMS key. Configure the KMS key policy to allow the development account and the production account to perform decrypt operations. Modify the pipeline to use the KMS key to encrypt artifacts.

D : the development account and in the production account, create an IAM role for CodePipeline. Configure the roles with permissions to perform CloudFormation operations and with permissions to retrieve and decrypt objects from the artifacts S3 bucket. In the CodePipeline account, configure the CodePipeline CloudFormation action to use the roles.

E : the development account and in the production account, create an IAM role for CodePipeline. Configure the roles with permissions to perform CloudFormation operations and with permissions to retrieve and decrypt objects from the artifacts S3 bucket. In the CodePipeline account, modify the artifacts S3 bucket policy to allow the roles access. Configure the CodePipeline CloudFormation action to use the roles.
