How should a secured S3 CloudFormation template be shared across AWS Organizations?

Implement a secure and consistent deployment strategy for cloud resources.

Answer Correct answer: A — Use AWS Service Catalog to create a portfolio and product from the secured S3 CloudFormation template, then grant end users access to the portfolio.

A security engineer writes an AWS CloudFormation template for a company. The template deploys a secured Amazon S3 bucket. The company wants to use the S3 bucket as a standardized template for all other S3 buckets. The template needs to be available to all the AWS accounts that are part of a single organization in AWS Organizations. Then, all end users can use the template to deploy new S3 buckets. Which solution will meet these requirements?

Use AWS Service Catalog to create a portfolio. Within the portfolio, create a new product by uploading the CloudFormation template for the secure S3 configuration. Grant access to end users by allowing access to the portfolio. Correct Answer
Use AWS Resource Access Manager (AWS RAM) to create a new resource share for the template. Select customer managed permissions and specify which IAM principals are allowed to access the shared resource.
Use AWS Resource Access Manager (AWS RAM) to create a new resource share for the template. Select AWS managed permissions for Amazon S3. Grant access to all AWS accounts in the organization.
Deploy the S3 bucket by using the template in an AWS account owned by the security engineer. Use AWS Resource Access Manager (AWS RAM) to share the bucket with all the other accounts within the organization for end users to use.

Community Insight

This question tests Service Catalog versus AWS RAM for distributing an approved CloudFormation template; the trap is treating an S3 resource share as a template-delivery mechanism.

A secured Amazon S3 CloudFormation template must be distributed to every account in an AWS Organization so end users can deploy standardized buckets. AWS Service Catalog meets this by publishing the template as an approved product in a shared portfolio, rather than sharing an S3 bucket through AWS RAM.

Candidates often pick AWS RAM because the scenario emphasizes cross-account sharing in AWS Organizations, but RAM shares supported resources such as S3 buckets, not CloudFormation templates.

AWS Service Catalog es el servicio ideal para este escenario porque: Permite crear y administrar catálogos de productos aprobados (como plantillas CloudFormation). Los usuarios finales pueden lanzar productos desde la cartera sin modificar la plantilla. Se puede compartir la cartera con todas las cuentas de la organización de AWS Organizations. Garantiza consistencia, seguridad y control sobre las configuraciones desplegadas. AWS Resource Access Manager (RAM) sirve para compartir recursos existentes, no para distribuir plantillas CloudFormation.

Expert Analysis

Why the Answer Is Correct

AWS Service Catalog is designed to let an administrator curate approved CloudFormation templates as products inside a portfolio, and end users launch those products without editing the underlying template. AWS Service Catalog supports sharing portfolios with accounts, organizational units, or an entire AWS Organization, which matches the requirement that every account in the single organization can use the secured S3 template. Each launch creates a new S3 bucket with the standardized configuration, preserving consistency and security. This is the correct mechanism for distributing a template as a governed self-service product, not merely sharing an existing S3 resource.

Why the Other Options Are Wrong

AWS RAM shares supported AWS resources and permissions, but it does not publish or distribute CloudFormation templates as launchable products. Option B's customer managed permissions and Option C's AWS managed permissions for Amazon S3 apply to resource sharing, so neither can make the template available for end users to deploy new S3 buckets. Option D shares the already-deployed S3 bucket itself, which means users would consume one shared bucket rather than instantiate new buckets from the standardized template. The template also should not be tied to a single security engineer's account for organization-wide deployment.

Community Comment Notes

Amantux selects A and explains that Service Catalog is the ideal service because it manages approved product catalogs such as CloudFormation templates. The comment notes that “Los usuarios finales pueden lanzar productos desde la cartera sin modificar la plantilla” and that the portfolio can be shared with all accounts in AWS Organizations. That aligns with the governance and standardization requirement in the question rather than with resource sharing through AWS RAM.

Exam Strategy

When a scenario asks for a standardized, approved artifact that other accounts can launch repeatedly, map it to Service Catalog rather than AWS RAM. AWS RAM is the right answer only when the shared item is a supported resource itself, such as a subnet, Transit Gateway, or S3 bucket, not a CloudFormation template.

Frequently Asked Questions

Why can't AWS RAM share the CloudFormation template across the organization?

AWS RAM shares supported AWS resources, not CloudFormation templates. To distribute an approved template for repeated deployments, use a Service Catalog product in a shared portfolio.

How does Service Catalog keep the secured S3 configuration standardized?

End users launch the product from the portfolio but cannot modify the underlying CloudFormation template. Each launch creates a new S3 bucket with the approved secure settings.
