AWS PrivateLink enables private connectivity between VPCs and AWS services without exposing traffic to the public internet. This feature is critical for meeting regulatory compliance standards that require isolation from public internet traffic.

Option A (Correct): "AWS PrivateLink": This is the correct answer because it allows secure access to Amazon Bedrock and other AWS services from a VPC without internet access, ensuring compliance with regulatory standards.

Option B: "Amazon Macie" is incorrect because it is a security service for data classification and protection, not for managing private network traffic.

Option C: "Amazon CloudFront" is incorrect because it is a content delivery network service and does not provide private network connectivity.

Option D: "Internet gateway" is incorrect as it enables internet access, which violates the VPC's no-internet-traffic policy.
