Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 471 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 471
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company is creating an application that runs on containers in a VPC. The application stores and accesses data in an Amazon S3 bucket. During the development phase, the application will store and access 1 TB of data in Amazon S3 each day. The company wants to minimize costs and wants to prevent traffic from traversing the internet whenever possible.

Which solution will meet these requirements?

  • A. Enable S3 Intelligent-Tiering for the S3 bucket
  • B. Enable S3 Transfer Acceleration for the S3 bucket
  • C. Create a gateway VPC endpoint for Amazon S3. Associate this endpoint with all route tables in the VPC
  • D. Create an interface endpoint for Amazon S3 in the VPC. Associate this endpoint with all route tables in the VPC

Amazon S3 supports both gateway endpoints and interface endpoints. With a gateway endpoint, you can access Amazon S3 from your VPC, without requiring an internet gateway or NAT device for your VPC, and with no additional cost. However, gateway endpoints do not allow access from on-premises networks, from peered VPCs in other AWS Regions, or through a transit gateway. For those scenarios, you must use an interface endpoint, which is available for an additional cost.

Selected Answer: C
Gateway VPC Endpoint: A gateway VPC endpoint enables private connectivity between a VPC and Amazon S3. It allows direct access to Amazon S3 without the need for internet gateways, NAT devices, VPN connections, or AWS Direct Connect. Minimize Internet Traffic: By creating a gateway VPC endpoint for Amazon S3 and associating it with all route tables in the VPC, the traffic between the VPC and Amazon S3 will be kept within the AWS network. This helps in minimizing data transfer costs and prevents the need for traffic to traverse the internet. Cost-Effective: With a gateway VPC endpoint, the data transfer between the application running in the VPC and the S3 bucket stays within the AWS network, reducing the need for data transfer across the internet. This can result in cost savings, especially when dealing with large amounts of data.

Option B (Enable S3 Transfer Acceleration for the S3 bucket) is a feature that uses the CloudFront global network to accelerate data transfers to and from Amazon S3. While it can improve data transfer speed, it still involves traffic traversing the internet and doesn't directly address the goal of minimizing costs and preventing internet traffic whenever possible.

https://aws.amazon.com/blogs/architecture/choosing-your-vpc-endpoint-strategy-for-amazon-s3/ A: Storage cost is not described as an issue here B: Tx Accelerator is for external (global user) traffic acceleration D: Interface endpoint is on-prem to S3 C: gateway VPC is specifically for S3 to AWS resources

Interface endpoints are not exclusively for on-prem to S3. The only reason why option D is wrong is because "Associate this endpoint with all route tables in the VPC" makes no sense.

I think both C&D will works. But D will have extra cost. So C is correct.
