A company’s application team wants to replace an internal application with a new AWS architecture...

Comprehensive and Detailed 100to 150 words of Explanation From AWS Certified Security – Specialty topics:

To keep application traffic off the public internet, EC2 and Lambda resources must reach S3 through private VPC networking. An S3 gateway endpoint provides private access from the VPC to S3 without using an internet gateway or NAT gateway. An S3 access point can also be restricted to VPC origin so S3 rejects requests that do not originate from the configured VPC path. The Lambda function must run inside the VPC so its S3 traffic can use the private endpoint path. Lambda “block public access” is not the relevant S3 network control. Security groups cannot target S3 gateway endpoints or S3 access points as destination resources in the way the distractors describe.
