Suggested Answer: B, C

To use AWS PrivateLink, you need to create interface type VPC endpoints for the services that you want to access privately from your VPC1. These endpoints appear as elastic network interfaces (ENIs) with private IPs in your subnets2. To enable DNS resolution for these endpoints, you need to set the enableDnsSupport attribute to True for your VPC, and enable DNS support for each endpoint3. You also need to ensure that the VPC endpoint policy allows communication between your VPC and the service4. You do not need to create any route table entries or Route 53 hosted zones for the endpoints, as they are not required for PrivateLink5.

I think the best solution is to configure VPC peering with static routing between the VPCs.
