A platform team has an approved CloudFormation template for operational monitoring. It must deploy and update that template across several AWS Organizations member accounts and two Regions from one management workflow. Which feature is designed for this task?

1. Create a nested stack in the management account and assume it deploys resources into all member accounts.
2. A CloudFormation export in one Region that automatically creates matching resources in every account.
3. An S3 replication rule on the template object alone.
4. CloudFormation StackSets with the appropriate service-managed permissions and deployment targets.
