Your company is planning to deploy EC2 Instances across multiple regions.
These instances will make calls to the Simple Storage service.
You are trying to understand the data transfer costs which are incurred in such an implementation.
Which of the following is not charged by AWS?
Click on the arrows to vote for the correct answer
A. B. C. D.Answer - B.
All data transfer into AWS via the Internet is not charged.
The AWS Documentation mentions the following on data transfer rates.
Billing prices are based on the location of your bucket.
There is no Data Transfer charge for data transferred within an Amazon S3 Region via a COPY request.
Data transferred via a COPY request between AWS Regions is charged at rates specified in the pricing section of the Amazon S3 detail page.
There is no Data Transfer charge for data transferred between Amazon EC2 and Amazon S3 within the same region, for example, data transferred within the US East (Northern Virginia) Region.
However, data transferred between Amazon EC2 and Amazon S3 across all other regions is charged at rates specified on the Amazon S3 pricing page, for example, data transferred between Amazon EC2 US East (Northern Virginia) and Amazon S3 US West (Northern California).
Options A, C and D are all invalid because all of the options will incur data charges.

https://aws.amazon.com/ec2/pricing/When you transfer data between different AWS services and regions, there may be additional data transfer fees. These fees vary depending on the source and destination of the data transfer.
The AWS data transfer pricing model is based on the source and destination regions, as well as the total amount of data transferred. The pricing model distinguishes between the following transfer types:
Intra-region data transfer: This refers to data transfers between AWS services located in the same region. Intra-region data transfer is usually free.
Inter-region data transfer: This refers to data transfers between AWS services located in different regions. Inter-region data transfer fees are based on the source and destination regions, and the total amount of data transferred.
Internet data transfer: This refers to data transfers between AWS services and the internet. Internet data transfer fees are based on the amount of data transferred.
Now let's look at each option:
A. From an Elastic Compute Cloud (Amazon EC2) in eu-west-1 to Amazon Simple Storage Service (Amazon S3) in us-east-1 This option involves inter-region data transfer, so there will be charges based on the amount of data transferred between eu-west-1 and us-east-1. Therefore, this option is not the correct answer.
B. From your on-premises data center to Amazon S3 in us-east-1 This option involves internet data transfer, so there will be charges based on the amount of data transferred between your on-premises data center and us-east-1. Therefore, this option is not the correct answer.
C. From Amazon EC2 in eu-west-1 to your on-premises data center This option involves internet data transfer, so there will be charges based on the amount of data transferred between eu-west-1 and your on-premises data center. Therefore, this option is not the correct answer.
D. From Amazon S3 in us-east-1 to Amazon EC2 in eu-west-1 This option involves inter-region data transfer, but it is different from option A because the data is being transferred from S3 to EC2 instead of from EC2 to S3. AWS does not charge for data transferred into EC2 instances, so this option is the correct answer.
