A company uses containers for its applications. The company learns that some container images are missing required security configurations.
A DevOps engineer needs to implement a solution to create a standard base image. The solution must publish the base image weekly to the us-west-2 Region, us-east-2 Region, and eu-central-1 Region.
Which solution will meet these requirements?

  1. Create an EC2 Image Builder pipeline that uses a container recipe to build the image. Configure the pipeline to distribute the image to an Amazon Elastic Container Registry (Amazon ECR) repository in us-west-2. Configure ECR replication from us-west-2 to us-east-2 and from us-east-2 to eu-central-1. Configure the pipeline to run weekly.
  2. Create an AWS CodePipeline pipeline that uses an AWS CodeBuild project to build the image. Use AWS CodeDeploy to publish the image to an Amazon Elastic Container Registry (Amazon ECR) repository in us-west-2. Configure ECR replication from us-west-2 to us-east-2 and from us-east-2 to eu-central-1. Configure the pipeline to run weekly.
  3. Create an EC2 Image Builder pipeline that uses a container recipe to build the image. Configure the pipeline to distribute the image to Amazon Elastic Container Registry (Amazon ECR) repositories in all three Regions. Configure the pipeline to run weekly.
  4. Create an AWS CodePipeline pipeline that uses an AWS CodeBuild project to build the image. Use AWS CodeDeploy to publish the image to Amazon Elastic Container Registry (Amazon ECR) repositories in all three Regions. Configure the pipeline to run weekly.

Answer(s): C



A company has configured Amazon RDS storage autoscaling for its RDS DB instances. A DevOps team needs to visualize the autoscaling events on an Amazon CloudWatch dashboard.
Which solution will meet this requirement?

  1. Create an Amazon EventBridge rule that reacts to RDS storage autoscaling events from RDS events. Create an AWS Lambda function that publishes a CloudWatch custom metric. Configure the EventBridge rule to invoke the Lambda function. Visualize the custom metric by using the CloudWatch dashboard.
  2. Create a trail by using AWS CloudTrail with management events configured. Configure the trail to send the management events to Amazon CloudWatch Logs. Create a metric filter in CloudWatch Logs to match the RDS storage autoscaling events. Visualize the metric filter by using the CloudWatch dashboard.
  3. Create an Amazon EventBridge rule that reacts to RDS storage autoscaling events from the RDS events. Create a CloudWatch alarm. Configure the EventBridge rule to change the status of the CloudWatch alarm. Visualize the alarm status by using the CloudWatch dashboard.
  4. Create a trail by using AWS CloudTrail with data events configured. Configure the trail to send the data events to Amazon CloudWatch Logs. Create a metric filter in CloudWatch Logs to match the RDS storage autoscaling events. Visualize the metric filter by using the CloudWatch dashboard.

Answer(s): A



A company has deployed an application in a single AWS Region. The application backend uses Amazon DynamoDB tables and Amazon S3 buckets.
The company wants to deploy the application in a secondary Region. The company must ensure that the data in the DynamoDB tables and the S3 buckets persists across both Regions. The data must also immediately propagate across Regions.
Which solution will meet these requirements with the MOST operational efficiency?

  1. Implement two-way S3 bucket replication between the primary Region's S3 buckets and the secondary Region’s S3 buckets. Convert the DynamoDB tables into global tables. Set the secondary Region as the additional Region.
  2. Implement S3 Batch Operations copy jobs between the primary Region and the secondary Region for all S3 buckets. Convert the DynamoDB tables into global tables. Set the secondary Region as the additional Region.
  3. Implement two-way S3 bucket replication between the primary Region's S3 buckets and the secondary Region's S3 buckets. Enable DynamoDB streams on the DynamoDB tables in both Regions. In each Region, create an AWS Lambda function that subscribes to the DynamoDB streams. Configure the Lambda function to copy new records to the DynamoDB tables in the other Region.
  4. Implement S3 Batch Operations copy jobs between the primary Region and the secondary Region for all S3 buckets. Enable DynamoDB streams on the DynamoDB tables in both Regions. In each Region, create an AWS Lambda function that subscribes to the DynamoDB streams. Configure the Lambda function to copy new records to the DynamoDB tables in the other Region.

Answer(s): A



A company uses an organization in AWS Organizations to manage its AWS accounts. The company's DevOps team has developed an AWS Lambda function that calls the Organizations API to create new AWS accounts.
The Lambda function runs in the organization's management account. The DevOps team needs to move the Lambda function from the management account to a dedicated AWS account. The DevOps team must ensure that the Lambda function has the ability to create new AWS accounts only in Organizations before the team deploys the Lambda function to the new account.
Which solution will meet these requirements?

  1. In the management account, create a new IAM role that has the necessary permission to create new accounts in Organizations. Allow the role to be assumed by the Lambda execution role in the new AWS account. Update the Lambda function code to assume the role when the Lambda function creates new AWS accounts. Update the Lambda execution role to ensure that it has permission to assume the new role.
  2. In the management account, turn on delegated administration for Organizations. Create a new delegation policy that grants the new AWS account permission to create new AWS accounts in Organizations. Ensure that the Lambda execution role has the organizations:CreateAccount permission.
  3. In the management account, create a new IAM role that has the necessary permission to create new accounts in Organizations. Allow the role to be assumed by the Lambda service principal. Update the Lambda function code to assume the role when the Lambda function creates new AWS accounts. Update the Lambda execution role to ensure that it has permission to assume the new role.
  4. In the management account, enable AWS Control Tower. Turn on delegated administration for AWS Control Tower. Create a resource policy that allows the new AWS account to create new AWS accounts in AWS Control Tower. Update the Lambda function code to use the AWS Control Tower API in the new AWS account. Ensure that the Lambda execution role has the controltower:CreateManagedAccount permission.

Answer(s): A



A DevOps engineer is setting up an Amazon Elastic Container Service (Amazon ECS) blue/green deployment for an application by using AWS CodeDeploy and AWS CloudFormation. During the deployment window, the application must be highly available and CodeDeploy must shift 10% of traffic to a new version of the application every minute until all traffic is shifted.
Which configuration should the DevOps engineer add in the CloudFormation template to meet these requirements?

  1. Add an AppSpec file with the CodeDeployDefault.ECSLinearl OPercentEveryl Minutes deployment configuration.
  2. Add the AWS::CodeDeployBlueGreen transform and the AWS::CodeDeploy::BlueGreen hook parameter with the CodeDeployDefault.ECSLinear10PercentEvery1Minutes deployment configuration.
  3. Add an AppSpec file with the ECSCanary10Percent5Minutes deployment configuration.
  4. Add the AWS::CodeDeployBlueGreen transform and the AWS::CodeDepioy::BlueGreen hook parameter with the ECSCanary10Percent5Minutes deployment configuration.
