[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company runs an application in a private subnet behind an Application Load Balancer (ALB) in a VPC. The VPC has a NAT gateway and an internet gateway. The application calls the Amazon S3 API to store objects.

Which solution will meet these requirements MOST cost-effectively?

  • A. Configure an S3 interface endpoint. Create a security group that allows outbound traffic to Amazon S3.
  • B. Configure an S3 gateway endpoint. Update the VPC route table to use the endpoint.
  • C. Configure an S3 bucket policy to allow traffic from the Elastic IP address that is assigned to the NAT gateway.
  • D. Create a second NAT gateway in the same subnet where the legacy application is deployed. Update the VPC route table to use the second NAT gateway.
