Your company has an AWS Direct Connect connection in the us-west region.
They are currently using a public VIF to access an S3 bucket in the us-west region.
They now want to make use of AWS Direct Connect to access an S3 bucket in the us-east region.
How can this be achieved most economically?

A. B. C. D.Answer - C.
The AWS Documentation mentions the following to support this.
AWS Direct Connect locations in public regions or AWS GovCloud (US) can access public services in any other public region (excluding China (Beijing))
In addition, AWS Direct Connect connections in public regions or AWS GovCloud (US) can be configured to access a VPC in your account in any other public region (excluding China (Beijing))
You can therefore use a single AWS Direct Connect connection to build multi-region services.
All networking traffic remains on the AWS global network backbone, regardless of whether you access public AWS services or a VPC in another region.
Option A is possible but is not the most economical route.
Option B is incorrect since a Private VIF cannot be used for public resources.
Option D is incorrect since you can make use of the current AWS Direct Connect connection.

https://docs.aws.amazon.com/directconnect/latest/UserGuide/remote_regions.htmlThe most economical way to access an S3 bucket in a different region through AWS Direct Connect is to create another Private VIF from the existing AWS Direct Connect connection. Option B is the correct answer.
Explanation: AWS Direct Connect allows you to establish a dedicated network connection between your on-premises data center and AWS. With Direct Connect, you can access resources in your Amazon Virtual Private Cloud (Amazon VPC) and also other AWS services such as Amazon S3.
In this scenario, the company already has an AWS Direct Connect connection in the us-west region and is currently using a public VIF to access an S3 bucket in the same region. Now they want to access an S3 bucket in the us-east region.
Option A, creating another AWS Direct Connect connection from the on-premises network in the us-east region, is not the most economical solution because it involves additional costs for setting up and maintaining another Direct Connect connection.
Option B, creating another Private VIF from the current AWS Direct connect connection, is the most economical option as it does not require additional Direct Connect connections. A Private VIF can be used to access resources in any region within the same AWS account as the existing Direct Connect connection. Therefore, the company can create a Private VIF to access the S3 bucket in the us-east region without incurring additional costs.
Option C, using the same Public VIF from the current AWS Direct Connect connection, is not feasible because public VIFs are used to access AWS services that have public endpoints. However, Amazon S3 does not have a public endpoint. Therefore, using a public VIF to access S3 buckets is not possible.
Option D, creating a VPN IPsec connection, is not the most economical solution because it involves additional costs for setting up and maintaining a VPN connection. Additionally, VPN connections have more overhead than Direct Connect connections, which can impact performance.
