Your company is planning to move its files from its on-premises location onto S3. The services hosted in the on-premises environment would need low latency access to these files. How can you achieve this?

Answer options:

A.Create a VPN connection that would allow the services on-premises to access S3.
B.Create a Direct Connect connection along with a Public VIF.C.Create a Direct Connect connection along with a Private VIF.D.Create a VPN connection along with a VPC endpoint.

Answer – B
This is also given in the AWS Documentation.
To connect to AWS public endpoints, such as an Amazon Elastic Compute Cloud (Amazon EC2) or Amazon Simple Storage Service (Amazon S3), with dedicated network performance, use a public virtual interface.
Option A is invalid since VPN connections don’t ensure low latency.
Option C is invalid since you need to have a Public VIF for public services such as S3.
Option D is invalid since VPC endpoints are invalid in this configuration.
