Identify AWS network services. Identify components and resources for security.

Short answer

B AWS PrivateLink provides private connectivity between VPCs and supported AWS services without exposing internal traffic to the public internet.

Question

A company wants to connect its supported AWS services and VPCs. The company does not want to expose its internal traffic to the public internet. Which AWS service will meet these requirements?
  1. Amazon Inspector
  2. AWS PrivateLink Correct Answer
  3. Amazon Connect
  4. AWS Internet Gateway

Key Takeaways

The question tests private service-to-VPC connectivity versus public internet exposure, and the trap is selecting an internet gateway simply because it provides connectivity.

AWS PrivateLink enables private connectivity between VPCs, supported AWS services, and on-premises networks without routing traffic over the public internet. This page confirms why PrivateLink is the correct choice over Amazon Inspector, Amazon Connect, and an internet gateway.

Common mistake: A common wrong choice is AWS Internet Gateway because it connects a VPC to the internet, but that is exactly what the company wants to avoid since it exposes traffic publicly.

Expert Analysis

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.

Exam Strategy

When a question says traffic must not go over the public internet, immediately eliminate internet gateway and any service that is not a private connectivity feature. Match the remaining options to the exact workload, here VPC-to-supported-AWS-service connectivity, which points to AWS PrivateLink.

Frequently Asked Questions

Why is an AWS Internet Gateway wrong for private VPC-to-service connectivity?

An internet gateway connects a VPC to the public internet, which risks exposing internal traffic. The question explicitly requires avoiding public internet exposure, so PrivateLink is the appropriate service.

Does AWS PrivateLink require VPC peering to connect to supported AWS services?

No. PrivateLink uses interface VPC endpoints to provide private access to supported AWS services without VPC peering, public IP addresses, or internet gateways.
