What response would you expect to receive from AWS?

You receive a bill from AWS but are confused because you see you are incurring different costs for the exact same storage size in different regions on Amazon S3. You ask AWS why this is so.

What response would you expect to receive from AWS?
A . We charge less in different time zones.
B . We charge less where our costs are less.
C . This will balance out next bill.
D . It must be a mistake.

Answer: B

Explanation:

Amazon S3 is storage for the internet. It’s a simple storage service that offers software developers a highly-scalable, reliable, and low-latency data storage infrastructure at very low costs.

AWS charges less where their costs are less.

For example, their costs are lower in the US Standard Region than in the US West (Northern California) Region.
