AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 56

A company provisions an AWS Direct Connect connection to permit access to Amazon EC2 resources in several Amazon VPCs and to data stored in private
Amazon S3 buckets. The Network Engineer needs to configure the company's on-premises router for this Direct Connect connection.
Which of the following actions will require the LEAST amount of configuration overhead on the customer router?

Answer options

• A. Configure private virtual interfaces for the VPC resources and for Amazon S3.
• B. Configure private virtual interfaces for the VPC resources and a public virtual interface for Amazon S3.
• C. Configure a private virtual interface to a Direct Connect gateway for the VPC resources and for Amazon S3.
• D. Configure a private virtual interface to a Direct Connect gateway for the VPC resources and a public virtual interface for Amazon S3.

Correct answer: D

Explanation

Option D is correct because using a Direct Connect gateway simplifies the routing configuration for the VPC resources while allowing public access for Amazon S3 through a public virtual interface. The other options require more complex setups, either by introducing additional private virtual interfaces or not utilizing the Direct Connect gateway effectively, leading to increased configuration overhead.
