A company has 50 member AWS accounts and wants to use AWS Transit Gateway to connect VPCs across those accounts. When a new member account is created, the company wants to automate creating a new VPC and attaching it to the Transit Gateway. Which combination of actions will achieve this? (Choose two.)

Sharing the Transit Gateway (TGW) from the management account to member accounts using AWS Resource Access Manager (RAM) is essential. RAM allows you to share AWS resources, including TGWs, across accounts within an AWS Organization. This enables member accounts to create attachments to the shared TGW. Deploying an AWS CloudFormation StackSet from the management account automates the creation of a new VPC and the TGW VPC attachment in the new member account. The StackSet can reference the shared TGW's ID to establish the connection. Incorrect options: AWS Organizations service control policies (SCPs) manage permissions but don't share resources like TGWs. Creating a peering TGW attachment is not the standard way to connect VPCs within the same TGW, and a service-linked role isn't used for sharing attachments in this manner. AWS Service Catalog is for sharing curated IT services, not for sharing infrastructure resources like TGWs directly for connectivity.
