Question
A company has many AWS accounts and uses AWS Organizations to manage all of them. A solutions architect must implement a solution that the company can use to share a common network across multiple accounts.
The company’s infrastructure team has a dedicated infrastructure account that has a VPC. The infrastructure team must use this account to manage the network. Individual accounts cannot have the ability to manage their own networks. However, individual accounts must be able to create AWS resources within subnets.
Which combination of actions should the solutions architect perform to meet these requirements? (Choose two.)
- A. Create a transit gateway in the infrastructure account.
- B. Enable resource sharing from the AWS Organizations management account. Correct
- C. Create VPCs in each AWS account within the organization in AWS Organizations. Configure the VPCs to share the same CIDR range and subnets as the VPC in the infrastructure account. Peer the VPCs in each individual account with the VPC in the infrastructure account.
- D. Create a resource share in AWS Resource Access Manager in the infrastructure account. Select the specific AWS Organizations OU that will use the shared network. Select each subnet to associate with the resource share. Correct
- E. Create a resource share in AWS Resource Access Manager in the infrastructure account. Select the specific AWS Organizations OU that will use the shared network. Select each prefix list to associate with the resource share.
Explanation
Option B is correct because enabling resource sharing from the AWS Organizations management account allows for cross-account access within the organization. Option D is correct as it involves creating a resource share in AWS Resource Access Manager within the infrastructure account to share specific subnets with designated AWS Organizations units (OUs), thereby allowing individual accounts to use these shared network resources without managing their own networks.
