Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 835 discussion

A company is expanding a secure on-premises network to the AWS Cloud by using an AWS Direct Connect connection. The on-premises network has no direct internet access. An application that runs on the on-premises network needs to use an Amazon S3 bucket.

Which solution will meet these requirements MOST cost-effectively?

  • A. Create a public virtual interface (VIF). Route the AWS traffic over the public VIF.
  • B. Create a VPC and a NAT gateway. Route the AWS traffic from the on-premises network to the NAT gateway.
  • C. Create a VPC and an Amazon S3 interface endpoint. Route the AWS traffic from the on-premises network to the S3 interface endpoint.
  • D. Create a VPC peering connection between the on-premises network and Direct Connect. Route the AWS traffic over the peering connection.

Selected Answer: C
A - Public VIFs route traffic over the public internet, but on-premises network has no direct internet access. B - NAT gateways provide internet access for resources within a VPC, but, again, on-premises network has no direct internet access. C - The traffic stays within AWS and the Direct Connect connection, ensuring security and compliance with the no-internet requirement. Also, this is cost-effective because it avoids the need for additional NAT gateways or public VIFs. D - Peering connections don't even support access to AWS public services like S3.

Option A is the correct answer: 1) I need to connect to public services only, thus public VIF will be enough. 2) Interface endpoints is charged per hour, not cost effective.

AnswerC Amazon S3 interface endpoint seems to be the best and only option as we are forced to use Private IP addressation. Interface endpoints for Amazon S3 Your network traffic remains on the AWS network. Use private IP addresses from your VPC to access Amazon S3 Require endpoint-specific Amazon S3 DNS names Allow access from on premises Allow access from a VPC in another AWS Region by using VPC peering or AWS Transit Gateway https://docs.aws.amazon.com/AmazonS3/latest/userguide/privatelink-interface-endpoints.html#types-of-vpc-endpoints-for-s3
