Question 431 - SAA-C03 discussion

A gateway VPC endpoint for Amazon S3 enables private connections between the VPC and Amazon S3 that do not require an internet gateway or NAT device. This minimizes costs and prevents traffic from traversing the internet. A gateway VPC endpoint uses a prefix list as the route target in a VPC route table to route traffic privately to Amazon S31. Associating the endpoint with all route tables in the VPC ensures that all subnets can access Amazon S3 through the endpoint.

Option A is incorrect because S3 Intelligent-Tiering is a storage class that optimizes storage costs by automatically moving objects between two access tiers based on changing access patterns. It does not affect the network traffic between the VPC and Amazon S32.

Option B is incorrect because S3 Transfer Acceleration is a feature that enables fast, easy, and secure transfers of files over long distances between clients and an S3 bucket. It does not prevent traffic from traversing the internet3.

Option D is incorrect because an interface VPC endpoint for Amazon S3 is powered by AWS PrivateLink, which requires an elastic network interface (ENI) with a private IP address in each subnet. This adds complexity and cost to the solution. Moreover, an interface VPC endpoint does not support cross-Region access to Amazon S3.
