The correct response is 'AWS Direct Connect' as it provides a private route from an on-premises network to the cloud provider's network, resulting in better bandwidth throughput and a more reliable network experience than internet connections. The Virtual Private Network (VPN) employs the public internet and is therefore not dedicated. Amazon Route 53 is not a connectivity service; it is a DNS web service. While AWS Transit Gateway does aid in managing network connectivity, it does not offer a dedicated physical link.
