A is incorrect: Adding routes to the PrivateLink endpoints in the route table is not necessary for endpoint communication D is incorrect: Creating a public hosted zone is not the right approach for private connectivity E is incorrect: While private hosted zones can be useful, they are not directly required to restore PrivateLink endpoint communication
The most effective steps are B and C. Ensuring that DNS support is enabled for both the VPC and the PrivateLink endpoints, along with verifying that the VPC endpoint policy permits the required access, will restore the necessary communication between the EC2 instances and the AWS services over the private network. These steps ensure that the services are correctly resolved and accessible while maintaining security and privacy through the AWS network.
A. This is not a VPC Gateway Endpoint. B. You need to use AmazonProvidedDNS, so this is doable option. C. VPC endpoint policy might block the connection, so possible cause. D & E. You don't need to use the R53 Hosted Zone for this scenario.
