Knowledge Hut Bank has a security requirement that all bank employees are required to log into a central identity solution, so that when they log on they gain access to central bank resources.

Each bank runs their VPC in the US-West-1 region, requires a high availability solution, and regulation does not allow each bank access to the others’ resources. How would you best design this solution? Create a Direct Connect connection from each VPC endpoint to the main Knowledge Hut Bank VPC. Migrate the acquired banks' AWS accounts to the main Knowledge Hut Bank account using migration tools such as Import/Export, Snapshot, AMI Copy, and S3 sharing. Create an OpenVPN instance in Knowledge Hut Bank ‘s VPC and establish an IPSec tunnel between VPCs. Create a VPC peering connection with Knowledge Hut Bank’s VPC peered to each branch's AWS account, ensuring that the peered subnets do not have an overlapping CIDR block range 20 / 20 An organization has created 15 IAM users.
