AWS Certified Solutions Architect – Associate (SAA-C03) — Question 83

A company runs a photo processing application that needs to frequently upload and download pictures from Amazon S3 buckets that are located in the same AWS Region. A solutions architect has noticed an increased cost in data transfer fees and needs to implement a solution to reduce these costs.
How can the solutions architect meet this requirement?

Answer options

• A. Deploy Amazon API Gateway into a public subnet and adjust the route table to route S3 calls through it.
• B. Deploy a NAT gateway into a public subnet and attach an endpoint policy that allows access to the S3 buckets.
• C. Deploy the application into a public subnet and allow it to route through an internet gateway to access the S3 buckets.
• D. Deploy an S3 VPC gateway endpoint into the VPC and attach an endpoint policy that allows access to the S3 buckets.

Correct answer: D

Explanation

The correct answer is D because deploying an S3 VPC gateway endpoint allows the application to connect to S3 without incurring data transfer costs associated with traversing the internet. Options A and C would increase costs due to internet data transfer, and option B does not effectively eliminate data transfer fees since a NAT gateway is primarily used for outbound internet traffic.
