Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 72 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 72
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

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?

  • 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*** The correct answer is Option D. Deploy an S3 VPC gateway endpoint into the VPC and attach an endpoint policy that allows access to the S3 buckets. By deploying an S3 VPC gateway endpoint, the application can access the S3 buckets over a private network connection within the VPC, eliminating the need for data transfer over the internet. This can help reduce data transfer fees as well as improve the performance of the application. The endpoint policy can be used to specify which S3 buckets the application has access to.

***WRONG*** Option A, deploying Amazon API Gateway into a public subnet and adjusting the route table, would not address the issue of data transfer fees as the application would still be transferring data over the internet. Option B, deploying a NAT gateway into a public subnet and attaching an endpoint policy, would not address the issue of data transfer fees either as the NAT gateway is used to enable outbound internet access for instances in a private subnet, rather than for connecting to S3. Option C, deploying the application into a public subnet and allowing it to route through an internet gateway, would not reduce data transfer fees as the application would still be transferring data over the internet.

Selected Answer: D
The best solution to reduce data transfer costs for an application frequently accessing S3 buckets in the same region is option D - Deploy an S3 VPC gateway endpoint into the VPC and attach an endpoint policy that allows access to the S3 buckets. The key points: - S3 gateway endpoints allow private connections between VPCs and S3 without going over the public internet. - This avoids data transfer fees for traffic between the VPC and S3 within the same region. - An endpoint policy controls access to specific S3 buckets.

Selected Answer: D
A. API Gateway can serve as a proxy for S3 requests, it adds unnecessary complexity and additional costs compared to a direct VPC endpoint. B. Using a NAT gateway for accessing S3 introduces unnecessary data transfer costs as traffic would still flow over the internet. C. This approach would incur data transfer fees as the traffic would go through the public internet. In comparison, option D using an S3 VPC gateway endpoint provides a direct and cost-effective solution for accessing S3 buckets within the same Region. By keeping the data transfer within the AWS network infrastructure, it helps reduce data transfer fees and provides secure access to the S3 resources.

The answer is D:- Actually, the Application (EC2) is running in the same region...instead of going to the internet, data can be copied through the VPC endpoint...so there will be no cost because data is not leaving the AWS infra

Can somebody please explain this question? Are we assuming the application is running in AWS and that adding the gateway endpoint avoids the need for the EC2 instance to access the internet and thus avoid costs? Thanks a lot.

Selected Answer: D FYI : -There is no additional charge for using gateway endpoints. -Interface endpoints are priced at ~ $0.01/per AZ/per hour. Cost depends on the Region - S3 Interface Endpoints resolve to private VPC IP addresses and are routable from outside the VPC (e.g via VPN, Direct Connect, Transit Gateway, etc). S3 Gateway Endpoints use public IP ranges and are only routable from resources within the VPC.
