A user has an S3 object in the US Standard region with the content “color=red”. The user updates the object with the
content as “color=”white”. If the user tries to read the value 1 minute after it was uploaded, what will S3 return?

A.
It will return “color=white”

B.
It will return “color=red”

C.
It will return an error saying that the object was not found

D.
It may return either “color=red” or “color=white” i.e. any of the value

Explanation:
AWS S3 follows the eventual consistent model in the US Standard Region. Once the object is updated it may return the
new value or the old value based on whether all the content is replicated across multiple servers until it becomes
consistent (eventual).
