How to Connect AWS Services and VPCs Without Public Internet Exposure?

Why the Answer Is Correct

AWS PrivateLink provides private connectivity between VPCs and supported AWS services using endpoints inside the AWS network, so traffic does not traverse the public internet. It is designed for securely exposing services to many VPCs without requiring VPC peering, public IP addresses, or internet gateways. This directly satisfies the requirement to connect supported AWS services and VPCs while keeping internal traffic private. As alokdixit2006 noted, PrivateLink "provides a private network connection between VPCs and AWS services."

Why the Other Options Are Wrong

Amazon Inspector is a vulnerability management service that scans workloads for security issues; it does not establish private network connectivity between VPCs and AWS services. Amazon Connect is a cloud contact center service and has no role in private VPC-to-service networking. AWS Internet Gateway attaches a VPC to the public internet, which is the opposite of the stated requirement because it can expose internal traffic. One learner summarized the reasoning simply: "B is the right answer by the process of elimination."

Community Comment Notes

Community responses consistently favor AWS PrivateLink, with Nikmah describing it as the "most secure & scalable way to expose a service to 1000s of VPCs." Another commenter, d00b229, explained that PrivateLink allows secure connections to supported AWS services and VPCs "without exposing your internal traffic to the public internet." The consensus aligns with the AWS documentation and with the wording of the question, which explicitly rules out public internet exposure. No commenter defended Amazon Inspector, Amazon Connect, or an internet gateway as the correct answer.
