Explanation

AWS PrivateLink is the correct solution because:

• Secure Private Connectivity: AWS PrivateLink enables you to privately access AWS services and other services hosted on AWS without exposing your traffic to the public internet
• VPC Endpoints: It uses VPC endpoints to create private connections between your VPC and AWS services
• No Internet Gateway Required: Traffic stays within the AWS network and never traverses the public internet
• Enhanced Security: Eliminates exposure to common internet-based threats

Why other options are incorrect:

• Amazon Connect: A cloud-based contact center service, not for VPC connectivity
• Amazon Inspector: A security vulnerability assessment service, not for network connectivity
• Internet Gateway: Actually exposes traffic to the public internet, which is the opposite of what's required

AWS PrivateLink provides the secure, private connectivity needed to connect on-premises VPCs to AWS services while keeping all traffic within the AWS network.
