QuestionQ108

Content Domain 3: Cloud Technology and Services

A company wants to securely access an Amazon S3 bucket from an Amazon EC2 instance without accessing the internet.

What should the company use to accomplish this goal?

  • A VPN connection
  • B Internet gateway
  • C VPC endpoint
  • D NAT gateway

A VPN connection, internet gateway, and NAT gateway all route traffic through, or require, internet connectivity, which the requirement explicitly rules out.
