How does Route 53 Resolver enable DNS resolution between a VPC and on premises networks?

Advanced

Answer

Route 53 Resolver automatically answers DNS queries for AWS resources within a VPC, and through Resolver endpoints and forwarding rules, it can also route DNS queries between your VPC and an on premises network connected through Direct Connect or VPN, allowing resources in either environment to resolve domain names hosted in the other, which is essential for hybrid cloud architectures.
