AWS Certified Advanced Networking - Specialty

  • Topic 1 Question 207

    A network engineer is working on a large migration effort from an on-premises data center to an AWS Control Tower based multi-account environment. The environment has a transit gateway that is deployed to a central network services account. The central network services account has been shared with an organization in AWS Organizations through AWS Resource Access Manager (AWS RAM).

    A shared services account also exists in the environment. The shared services account hosts workloads that need to be shared with the entire organization.

    The network engineer needs to create a solution to automate the deployment of common network components across the environment. The solution must provision a VPC for application workloads to each new and existing member account. The VPCs must be connected to the transit gateway in the central network services account.

    Which combination of steps will meet these requirements with the LEAST operational overhead?

    • Deploy an AWS Lambda function to the shared services account. Program the Lambda function to assume a role in the new and existing member accounts to provision the necessary network infrastructure.

    • Update the existing accounts with an Account Factory Customization (AFC). Select the same AFC when provisioning new accounts.

    • Create an AWS CloudFormation template that describes the infrastructure that needs to be created in each account. Upload the template as an AWS Service Catalog product to the shared services account.

    • Deploy an Amazon EventBridge rule on a default event bus in the shared services account. Configure the EventBridge rule to react to AWS Control Tower CreateManagedAccount lifecycle events and to invoke the AWS Lambda function.

    • Create an AWSControlTowerBiueprintAccess role in the shared services account. F Create an AWSControlTowerBiueprintAccess role in each member account.
