Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 562 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C02
Question #: 562
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C02 Questions]

A solutions architect is creating an application. The application will run on Amazon EC2 instances in private subnets across multiple Availability Zones in a VPC.
The EC2 instances will frequently access large files that contain confidential information. These files are stored in Amazon S3 buckets for processing. The solutions architect must optimize the network architecture to minimize data transfer costs.
What should the solutions architect do to meet these requirements?

  • A. Create a gateway endpoint for Amazon S3 in the VPC. In the route tables for the private subnets, add an entry for the gateway endpoint.
  • B. Create a single NAT gateway in a public subnet. In the route tables for the private subnets, add a default route that points to the NAT gateway.
  • C. Create an AWS PrivateLink interface endpoint for Amazon S3 in the VPC. In the route tables for the private subnets, add an entry for the interface endpoint.
  • D. Create one NAT gateway for each Availability Zone in public subnets. In each of the route tables for the private subnets, add a default route that points to the NAT gateway in the same Availability Zone.

Both Answer A that uses GW VPC Endpoint and Answer C that uses Interface VPC Endpoint are actually routing traffic via the AWS PrivateLink containing the traffic within AWS cloud without traversing to the public internet. Thus both would reduce the data transmission cost. S3 does support both type but I think it is preferable to use GW VPC Interface. So I opt for Answer A.
